I am trying to run my pharo2.0 application on CentoOS which was previously been installed in a mac. The original version is pharo2.0 so I need to run the same image CentoOS too, but I get an error which says this below :
/lib/libc.so.6: version `GLIBC_2.15' not found (required by xxxxx)
Should I be trying to upgrade the CentoOS and see if pharo2.0 works or port my whole application to a later version of pharo?
There is now a VM build especially for systems with an older libc version. In fact there is a build for Centos specifically (which has a slight variation in linkages from Debian), the latest version of which is permalinked here. See http://pharo.org/download#custom for more info.

I've inherited an application server which I need to maintain/upgrade.
It's currently running Windows Server 2008R2, ColdFusion 9.02 32-bit and Apache 2.4 32-bit.
Because I want to upgrade/debug/alter the CF source code, I want to use FusionReactor to help me, especially the (line)debugging part.
Unfortunately, FusionReactor only runs (well, the debugging part) on 64bit java. Because the CF application is quite old, it's not ready to run on a newer CF version yet (and I want to port it to Lucee eventually). So, that leaves me the option of CF 9.02 64bit. Problem there is, that it won't run out of the box on Apache 2.4 (only 2.2).
CF 9.02 32bit is currently running on Apache 2.4 because I compiled/patched an Apache 2.2 module (mod_jrun22.so) so it works on Apache 2.4 (with the help of this https://g0blin.co.uk/mod_jrun-on-apache-2-4-ubuntu-14-04-coldfusion-9/ )
Unfortunately, I'm unable to do the same for Apache 2.4 64bit, because there seems to be no apxs 64bit available.
I could downgrade Apache 2.4 -> 2.2, but that's only my last resort.
Now my question. Is somebody able to recompile this module for 64bit, or give me some guidelines to do so? Is apxs available for 64bit? If not, Is there a simple way to compile (custom) modules for Apache 2.4 64bit?
Thanks!

Run it by ./apache_connectors.sh
If you get a GCC not found error, you might have to install some development tools,
to allow you to build the connector.
yum groupinstall 'Development Tools'
You might reach out to Gavin, the author of that article to see if he has any further notes. It's been forever and a day since I had to deal w/ 32-bit CF. I know I managed to get CF 8 to run on 64-bit, which was never officially supported IIRC, but I don't have any of those notes anymore.
You might look to using CommandBox to run your server instead of Apache. It might make your conversion to Lucee easier too. The only reason to convert the engine depends on how much new code is being written for this application. You can get away with CF 9 without the effort of upgrading or converting.
I am currently working from Mono Version 3.2.8 and am running into trouble finding any documentation on this version. I have no idea what code will run until after I get the exceptions. Either a compatibility list to what works or an idea of what version I can compile that works would be great. Any one have experience with this?
You can manually install the latest version. I was easily able to install
Mono version 4.6.2 on Raspbian.
The http://www.mono-project.com/docs/ site gives a general answer for which major libraries work. Letting you know when there isn't full compatibility but doesn't give specifics.
A penetration test has recently identified that one of our RHEL(6.7) servers running Apache 2.2.15 is vulnerable on a number of points and needs to be updated to the latest version 2.4. I have run yum update and it says that there are no packages marked for update. I understand that I will need to download the updates manually. There are a few questions I have around the requirement to upgrade Apache.
I am up to date on the 2.2 version tree. Does this mean that any security patches made to version 2.4 will be back patched to version 2.2.X as well?
I am running PHP (version 5.3.3) and MySQL (version 5.1.73) - will these be affected by upgrading the Apache version (Google tells me that there is no problem on both fronts - but I thought I'd ask before I started down this route).
If you experts tell me that I have no other choice but to upgrade, then I'm planning on using the instruction set here: https://unix.stackexchange.com/questions/138899/centos-install-using-yum-apache-2-4
Thank you in advance for your advice.
You could download the 2.4 source code from the Apache site and compile it. There's a setting which will configure for RedHat:
--enable-layout=RedHat
This setting will configure the paths for executables, configuration files, libraries etc in one go.
The following should be a reasonable starting point for a configuration line:
sh ./configure --enable-layout=RedHat --enable-mods-shared=all
then perform a make and make install
Do the same with a newer version of PHP (5.3.29 is available in the "old downloads" section, but try a newer version. Check the changes first though) and your problems should be lessened. Finally, MySQL or MariaDB is available for download and compilation too
Obviously, try all of this on a test machine first and back everything up. Your test machine should be as close as possible to your production machine. If you use something like VirtualBox to try it, you can take a snapshot at each point of the process and rollback if something goes wrong
I am attempting to start Apache Geronimo using the command:
./bin/geronimo run
When I do this, it spins for a minute, issues the message "Main not found" and exits.
This article suggests that it is a system resource issue:
http://apache-geronimo.328035.n3.nabble.com/jira-Created-GERONIMO-5551-Failing-to-start-the-server-with-the-error-quot-Main-not-found-quot-td1324013.html
I have tried it on both an Amazon EC2 box (running Linux), and an Azure A1 box (running Windows Server), and I have tried the "Full Profile Release" and "Web Profile Release" of Geronimo, all with no change.
I'm at a complete loss as to what I could try. I am led to believe that the EC2 box, at the very least, should have the muscle to run Geronimo.
Any suggestions would be welcome.
Version 3 of Apache Geronimo is designed to run on JRE 1.7 instead of JRE 1.8. As stated in the other answers, the issue was caused by Geronimo being run on JRE 1.7 instead of 1.8.
You are not limited to JRE 1.7 and earlier in order to run Geronimo though. Therefore, all you have to do is to rename or copy the property jre-1.7 in the file etc/config.properties in your installation to jre-1.8. Afterwards, you should be able to run Geronimo without an error.
This has a huge benefit, since now you will be able to run programs on Geronimo that use Java 8 features.
It turns out that the issue is that I had the wrong version of the JDK installed. I had installed the most recent version (8), but Geronimo apparently won't work with that. When I instead installed version 6, everything worked fine.
I was getting the same error with Java 8. I tried the latest version of Java SE 7 and that resolved the problem. So I wouldn't use Java 6, since it is and has been out of support for awhile now (read: security issue).
I attempted to update my version of SVN from 1.7 to 1.8 as per this guide:
http://snippets.khromov.se/subversion-1-8-centos-6/
All seemed to install fine, however now I have an issue when I try to restart Apache:
/usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_crypto_init
Does anyone know how to solve this?
Which packages need to be updated?
I had same issue after installing some perl modules.
I did the following to resolve it:
yum remove vulture-common-3.2-185.1.x86_64
cd /usr/lib
ln -sf libaprutil-1.so.0.2.9 libaprutil-1.so.0
ln -sf libapr-1.so.0.2.9 libapr-1.so.0
apr_crypto_init is new with APR-Util 1.4.x. CentOS 6 should already have APR-Util 1.4.x. So either you're not using CentOS 6 which those instructions are made for or you're not using the apr-util/httpd version that comes with CentOS 6.
If you're not using CentOS 6 then I suggest you go get a version built for your distribution from WANdisco's download site (the script that the site you linked to actually is from WANdisco).
If you're using your own httpd version you'll either have to switch or you'll have to build your own copy of Subversion.
I have had similar experiences with other applications using this library and Centos 6.x. I have tracked most of the problems down to using the 'minimum install' version of the OS. From what I have been able to determine, the minimum or light install versions of Centos have a tendency to have older versions of the binaries. For example, my version of APR-Utils are 1.3x even though I am using version 6.6.
This is supposedly done for better stability and backward compatibility from what I can find but it causes some headaches if you aren't aware. You may need to use a more 'complete' version of the OS in order for this library to be the latest version, provided you are starting from scratch.
