how to get trac to run with apache? - apache

i have some problems getting trac to be running with apache.
have no idea of how to do and the tutorial i followed doesnt work.
http://trac.edgewall.org/wiki/TracModPython
i have an empty /etc/apache2/httpd.conf. should it be empty?
then i followed the tutorial and typed in:
LoadModule python_module modules/mod_python.so
so now it contains one row. i have ubuntu and i installed mod_python with:
apt-get install libapache2-mod-python libapache2-mod-python-doc
however, when i run a2enmod mod_python it says:
ERROR: Module mod_python does not exist!
but i have checked that it exists in /usr/lib/apache2/modules/mod_python.so.
so whats the problem?

Usually, installing mod_python via:
apt-get install libapache2-mod-python
will enable it. If it does not, the correct command is:
a2enmod python
note, the module is 'python', not 'mod_python'.

First, your httpd.conf may be empty, but you should also have a apache2.conf in the same directory that actually contains all the server directives.
As for the module, I was having the same issue and then did some digging. If you look in /etc/apache2/mods-enabled, you should have one in there called "python.load" (I do at least). If you open that up with vi, you will notice the following line in that file:
LoadModule python_module /usr/lib/apache2/modules/mod_python.so
I think that it may just be that its installed with a different name. If someone else knows different, I would be interested in hearing their views as well.

How do I compile Tomcat mod_jk on a MacBook Pro M1 chip?

I have Homebrew Apache installed and trying to connect Coldfusion Server 2016 with Tomcat mod_jk.
I downloaded the source code from https://tomcat.apache.org/download-connectors.cgi
I followed the directions to compile it, tried few different ways, but when I get to the "make" command, I keep getting the same error:
In file included from jk_ajp12_worker.c:26:
In file included from ./jk_ajp12_worker.h:26:

#error Can not determine the proper size for pthread_t
^
2 errors generated.
make[1]: *** [jk_ajp12_worker.lo] Error 1
make: *** [all-recursive] Error 1
These are the different commands I've tried to compile:
./configure --with-apxs=/opt/homebrew/bin/apxs
./configure CFLAGS='-arch arm64e' APXSLDFLAGS='-arch arm64e' --with-apxs=/opt/homebrew/bin/apxs
./configure CFLAGS='-arch arm64e' APXSLDFLAGS='-arch arm64e' --with-apxs=/opt/homebrew/bin/apxs --host=arm
I recently got this new MacBook Pro 16" and migrated everything over from my 2017 MacBook Pro (Intel chip). I was running stock Apache with Coldfusion Server 2016, but when I tried to start up Apache on the new MacBook, it didn't like my mod_jk.so file and threw an error:
httpd: Syntax error on line 542 of /opt/homebrew/etc/httpd/httpd.conf: Syntax error on line 2 of /opt/homebrew/etc/httpd/mod_jk.conf:
Cannot load /Applications/ColdFusion2016/config/wsconfig/2/mod_jk.so into server: dlopen(/Applications/ColdFusion2016/config/wsconfig/2/mod_jk.so, 0x000A):
tried: '/Applications/ColdFusion2016/config/wsconfig/2/mod_jk.so'
(mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e'))
I appreciate any help or input. Thank you.
I've finally installed Apache2 with Tomcat on my M1 and it all works.
The one thing you must do is to install a fresh Apache from Macports or HomeBrew. This is because most old installations copied from your old mac to your new one will now be in the read-only part of your file system and SIP won't let you near them. You will find weird and wonderful workarounds (apachectl told me I had to codesign mod_jk.so for example and I wasted a lot of time doing it and in the end it was pointless) and you will attempt to get the old installation to work, but trust me it's not worth it.
You will need to compile a fresh jk_module (mod_jk.so). This is what I did:
Download latest connector https://dlcdn.apache.org/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.48-src.tar.gz, save the .gz and unzip it.
Change directory to the native folder.
run which apxs to tell you the path to apxs for the ./configure command
The path mine gave was: /opt/local/bin/apxs. Use it as the path in the ./configure command below.
The commands are as follows (actually don't bother running them yet because they will fail):
./configure --with-apxs=/opt/local/bin/apxs
make
However make will fail with:
./jk_types.h:56:2: error: Can not determine the proper size for pid_t
#error Can not determine the proper size for pid_t
^
./jk_types.h:62:2: error: Can not determine the proper size for pthread_t
#error Can not determine the proper size for pthread_t
^
2 errors generated.
make[1]: *** [jk_ajp12_worker.lo] Error 1
make: *** [all-recursive] Error 1
This is a problem for M1 macs that has been fixed. So for the moment we will abandon the 1.2.48 source and download the source with the fix.
But don't delete the 1.2.48 source because the fix source is missing a few files which you will copy straight over from the 1.2.48 source.
The page to download the fix for Mac OS is here: https://github.com/apache/tomcat-connectors, which is commit e719874 on Jun 30, 2021.
Click on the green 'Code' button and then on 'Download ZIP'.
Unzip the new source and cd to 'native'
Run the commands:
./configure --with-apxs=/opt/local/bin/apxs
make
And whenever it stops and complains that something is missing, find it in the 1.2.48 source and copy it over to the same position in the new source and try again. It will happen two or three times.
I got this error at one point:
/home/myuser/source/mod_auth_cas/mod_auth_cas/missing: line 81: aclocal-1.15: command not found
WARNING: 'aclocal-1.15' is missing on your system.
You should only need it if you modified 'acinclude.m4' or
'configure.ac' or m4 files included by 'configure.ac'.
The 'aclocal' program is part of the GNU Automake package:
<http://www.gnu.org/software/automake>
It also requires GNU Autoconf, GNU m4 and Perl in order to run:
<http://www.gnu.org/software/autoconf>
<http://www.gnu.org/software/m4/>
<http://www.perl.org/>
make: *** [aclocal.m4] Error 127
Then I read somewhere to run autoreconf -f -i (which fixed it).
When make finishes, find your nice new mod_jk.so file in the native/apache-2.0 folder and copy it to where all your other modules are. I have a Macports installation so Homebrew is probably different, but my modules are in /opt/local/lib/apache2/modules.
Don't forget to add the LoadModule line in httpd.conf if it isn't already there:
LoadModule jk_module /opt/local/lib/apache2/modules/mod_jk.so
You might have some trouble working out which apache2 folders contain the new install, and not an old installation - I found two other installations knocking about trying to confuse me.
My config is here: /opt/local/etc/apache2/httpd.conf
apachectl is very useful for configuration.
apachectl -t -D DUMP_INCLUDES will find all the configuration files it is using. This totally saved me because it showed me that my httpd.conf file, which I had copied from elsewhere, was still pointing via 'Include' commands at other old config files in the wrong place.
apachectl configtest will test your config for you and print out any mistakes it finds. It pointed at 4 modules that it didn't like so I just excluded them. Though obviously read the messages carefully and google if you are not sure why apachectl doesn't like something. If it replies 'Syntax OK' you are ready to go.
This is a mysterious message I got a lot until I worked out that it was because httpd.conf was pointing at the wrong modules folder (an old install of apache2) for each module, so it was loading stuff that presumably was not compiled for 64bit
httpd: Syntax error on line 76 of /opt/local/etc/apache2/httpd.conf:
Cannot load libexec/apache2/mod_authz_owner.so into server:
dlopen(/usr/libexec/apache2/mod_authz_owner.so, 0x000A): symbol not
found in flat namespace '_apr_stat$INODE64'
This is my launch command using the plist which Macports automatically created:
sudo launchctl load -w /opt/local/etc/LaunchDaemons/org.macports.apache2/org.macports.apache2.plist
And to unload:
sudo launchctl unload /opt/local/etc/LaunchDaemons/org.macports.apache2/org.macports.apache2.plist
run ps ax|grep httpd to see if it's running.
Logging: Don't forget to sudo to create the jk folder in /var/log/apache2 if it doesn't already exist, otherwise apache or tomcat will have mysterious problems or won't start or something (the /var/log/apache2/jk folder is needed for jk.log).
Another problem cropped up just as I thought I had it made: apache
was unable to write its pid file on startup. Again this was because the position set in my config for the pid file was from the configuration on my old mac, and the position chosen was in a read-only location.
To change this you need to set the PidFile parameter, which I found in the following file:
/opt/local/etc/apache2/extra/httpd-mpm.conf
and it looks like this:
# PidFile: The file in which the server should record its process
# identification number when it starts.
#
# Note that this is the default PidFile for most MPMs.
#
<IfModule !mpm_netware_module>
PidFile "local/run/apache2/httpd.pid"
</IfModule>
Don't worry about what the IfModule thing is doing, just set the PidFile to a writeable location, which as you can see is a relative path. You may be wondering what goes in front of the local folder.
What goes in front is the ServerRoot parameter set in httpd.conf:
ServerRoot "/usr"
So my pid will be written at /usr/local/run/apache2/httpd.pid. I had to create the run and apache2 folders.
That's about it. There are various logs that might indicate errors if you are stuck:
/var/log/apache2/error_log
And the jk.log for the apache/tomcat connector:
/var/log/apache2/jk/jk.log
And there's always the system log which just might tell you something:
/var/log/system.log
I hope very much that this helps someone. However it was very long and complicated and I have surely missed something that I did along the way, so if you come across some new problem I will see if I can help.
Running ColdFusion on a Mac is consistently a PITA. Doesn't matter if it's CF 9, 10, 11, all the way to current. Especially when you're dealing with a non-Intel based chipset. You are also trying to get an older and custom build of Toncat running on a chipset that likely isn't supported. You're also not the only one having this issue with CF 2016 on the M1 chip (they didn't find a solution either).
Try using CommandBox to run CF. It will download the server as a JAR file and run it on the Glassfish servlet container (IIRC). You won't need Apache either. It's really quite simple to get up and running.
https://commandbox.ortusbooks.com/embedded-server/multi-engine-support
Once you have it installed, go to your application's root folder in the CLI:
start cfengine=adobe#2016
It will download & install the server, then start the application.
Check the docs for more info.

Apache - ScriptAlias: Command not found

When I try to run the command ScriptAlias, I always get the error:
ScriptAlias: command not found
I have made sure that the alias mod is enabled through a2enmod alias, and I have ran apt-get update a few times as well. Does anyone know what could be causing this?
I realized that I did not understand how the module worked, and was trying to use the command directly into the command line. I needed to edit the 000-default.conf file instead.

apache2.4 , where to setup mod_ssl, dont see any mod_ssl.so file

Problem is the plain vanila apache is working, the moment I say sslEngine ON
it gives error, I am not able to find where any ssl setup is?
it does not create any log as well..
How this ssl setup is done? will copying a mod_ssl.so file from outside will work?
Apache version : 2.4.29
Os is RHEL 6.7
If this Red Hat documentation is not wrong the RHEL 6.x releases include Apache/2.2. Since you have Apache/2.4 I'd say you probably have an unofficial binary. Such binaries could of course have been installed in any conceivable way so this answer can easily be wrong. Yet making the hopefully safe assumption that you're still using the package manager and you just switched to a third-party repository you can try this:
yum install mod_ssl
Then tweak /etc/httpd/conf.d/ssl.conf to your liking and restart the service:
service httpd graceful
After a lot of research, I found below command which can help you show the actual issue while restarting. when I ran this it told me that .csr which I was using were wrong. I could not get this when I normally started the Apache but this command helped.
replace below with location where apache is installed and conf file is located, this will print the error ( if any).
/xxx/app/xxx/apache22/0/bin/apachectl_worker -DSSL -k start -f /xxx/app/xxx/apache22/0/conf/xxx.conf

Create local debian repository

My goal is to demonstrate creating a local debian repository with controlled versions of tools used (e.g. compiler versions) to make a build system more predictable.
I've tried to follow this example: http://linuxconfig.org/easy-way-to-create-a-debian-package-and-local-package-repository
but when I get to the apt-get update stage, I always get a 404 not found on the repository I've added.
The apache2 server is running, I can view the default page installed at http://localhost/html/index.html.
I am trying this with the file fortune-mod_1%3a1.99.1-7_amd64.deb installed to /var/www/debs. I create the Packages.gz file as the tutorial suggests:
dpkg-scanpackages debs /dev/null | gzip -9c > debs/Packages.gz
I also add a new file: /etc/apt/sources.list.d/myppa.list with this line:
deb http://localhost debs/
I restart the apache2 service just in case:
sudo service apache2 restart
but running:
sudo apt-get update
still produces this error:
W: Failed to fetch http://localhost/debs/Packages 404 Not Found
Is there something basic I'm missing? Ultimately, I'd like to get this working over a LAN, but first have to get it working on a single machine.
EDIT: I'm doing this on Ubuntu 14.04.
EDIT: Show contents of file /etc/apt/sources.list.d/myppa.list
tldr; use aptly
It's the easiest apt repository management tool I've found and it comes with neat tutorial showing how to create, populate, and publish your own apt repository.
References:
https://www.aptly.info/
https://www.aptly.info/tutorial/repo/
I ended up solving the problem. It was an issue with the default document root being different for the tutorial than on my system. All I did was move my debs folder to html (document root turns out to be /var/www/html, not just /var/www on my install). That did the trick.

Apache is "Unable to initialize module" because of module's and PHP's API don't match after changing the PHP configuration

php -v gives this
PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20060613
PHP compiled with module API=20090626
These options need to match in Unknown on line 0

ps. i've upgraded from php 5.2 to 5.3. before this everything worked okay.
When you update the version of PHP (especially when going from version X.Y to version X.Z), you must update the PHP extensions as well.
This is because PHP extensions are developped in C, and are "close" to the internals of PHP -- which means that, if the APIs of those internals change, the extension must be re-compiled, to use the new versions.
And, between PHP 5.2 and PHP 5.3, for what I remember, there have been some modifications in the internal data-structures used by the PHP engine -- which means extensions must be re-compiled, in order to match that new version of those data-structures.
How to update your PHP extensions will depend on which system you are using.
If you are on windows, you can find the .dll for some extensions here : http://downloads.php.net/pierre/
For more informations about the different versions, you can take a look at what's said on the left-sidebar of windows.php.net.
If you are on Linux, you must either :
Check what your distribution provides
Or use the pecl command, to re-download the sources of the extensions in question, and re-compile them.
just
pecl uninstall module_name
then
pecl install module_name
Your problem is within the php5-dev package. I guess you went from php5.2 on an older linux version to php5.3. I did the same thing, and when I managed to install php 5.3 there was a conflict with php5-dev. For some reason it doesn't get upgraded to the new version. Dunno why is that and I don't care, however this makes your extension compiled with the older API version, while php ofc is with the newer api version. What I did to solve this problem was:
I removed php5-dev with
sudo apt-get remove php5-dev, then I ran sudo apt-get autoremove to get rid of the leftovers that were giving me the trouble, and after that I just installed php5-dev again.
sudo apt-get install php5-dev.
Once that was done, I removed my memcache with sudo pecl uninstall memcache and installed it again sudo pecl install memcache. Now both the module and the php had the same api version so I knew right away that I had the issue solved :)
Hope it helps.
It's possible that the modules are installed, but your PHP.ini still points to an old directory.
Check the contents of /usr/lib/php/extensions. In mine, there were two directories: no-debug-non-zts-20060613 and no-debug-non-zts-20060613. Around line 428 of your php.ini, change:
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613"
to
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"
Then restart apache. This should resolve the issue.
I struggled with this issue for a long time and found out that when you run configure, just pass it the path to the correct php-config tool.
In my case, it was
./configure --with-php-config=/usr/local/zend/bin/php-config
... If you're unsure, run a locate php-config on your machine and find the right one amongst the different versions installed.
Hope this helps somebody in the future.
PS. My default php-config was set to 20090926 which is PHP 5.3. The one I manually entered as a param for ./configure was for PHP 5.4 (2010...)
I had this part enabled in my php.ini
extension=php_memcache.dll
[Memcache]
memcache.allow_failover = 1
memcache.max_failover_attempts=20
memcache.chunk_size =8192
memcache.default_port = 11211
After commenting these lines composer was installed in my windows 10
I had a similar issue after upgrading from PHP 5.5 to PHP 5.6. The phpize and php-config libraries being used to compile the phalcon extension were still the ones from PHP 5.5. I had to run the command below:
sudo apt-get install php5.6-dev
There will be a long stacktrace, the key information I saw was this:
update-alternatives: using /usr/bin/php-config5.6 to provide /usr/bin/php-config (php-config) in auto mode
update-alternatives: using /usr/bin/phpize5.6 to provide /usr/bin/phpize (phpize) in auto mode
I hope this helps someone.
Before you phpize, make sure to update your path ($PS1) to point to the new PHP! phpize uses your environment, and if you still have vestiges of your old PHP in your path or other parts of the environment, things will get hairy!
I'd the same error even after recompiling the modules.
But I solved it you just have to specify the absolute path of your phpize.
Here is the one that works with php 5.5. Download xampp 1.8.3 from here and download memcache dll from here
In my case in php.ini
[CLDbg]
extension=php_cl_dbg_5_3_VC9.dll
clport=6000
I removed Codelobster which support different PHP version, so need to update to:
[CLDbg]
;extension=php_cl_dbg_5_3_VC9.dll
;clport=6000
This problem has just happened to me and has been solved simply by increasing
memory_limit from 32 M to 64 M
You can adjust the value on the file where php.ini exists
locate php.ini
then choose the right file and search for memory_limit and after modifying it
you must reboot the apache
/etc/init.d/httpd restart
All the best.
In my case, I used lnmp to install php with version 5.4.45. But maybe because I installed php5-dev after lnmp (which I guess is not necessary if you installed lnmp), my phpize and php-config both point to older version tools than php.
I solved this by change the soft link of /etc/alternatives/phpize and /etc/alternatives/php-config to /usr/local/php/bin/phpize and /usr/local/php/bin/php-config.
Hopes this is helpful.
What worked for me was simply to do the following:
open the php.ini file.
Under the DYNAMIC EXTENSIONS heading, comment out the following line as
;extension=php_java.dll
Restarted Apache and all was fine
