I'm a Digitalocean user and I'm trying to migrate mi infraestructre from Centos 7 to Centos 8
It implies moving DBs (mysql), set a Web Server and Java.
One of the steps is installing Apache and Tomcat making use of mod_jk.
All the steps I will describe end in a complete succes in Centos 7 but fails in Centos 8
The way i got Java installed was by a RPM package I downloaded from oracle itself.
# java -version
java version "14.0.1" 2020-04-14
Java(TM) SE Runtime Environment (build 14.0.1+7)
Java HotSpot(TM) 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)
These are all the steps I follow.
# dnf install httpd
#cd /tmp
# wget https://apache.zero.com.ar/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.48-src.tar.gz
# cd tomcat-connectors-1.2.48-src/native
# dnf install httpd-devel
# dnf install make
# dnf install libtool
# which apxs
/usr/bin/apxs
In this directory there's the file "BUILDING.txt" with instructions to install which I follow.
It looks like this.
# ./configure --with-apxs=/usr/bin/apxs
# make
And here there is seem to be the problem.
Some "redhat" directory not found in Centos.
Error when executing 'Make' screenshot
The next would be
# make install
But is fails in Centos 8
Does anyone know how to solve this?
Thanks in advance.
You need to install redhat-rpm-config. Install redhat-rpm-config and test.
yum install redhat-rpm-config

I have RedHat Enterprise Linux Server 7, and I downloaded the linux kernel version 4.12.10 which I am trying to compile but when I execute the following command:
make modules
I get the following error:
scripts/sign-file.c:25:30: fatal error: openssl/opensslv.h: No such file or directory
Does anyone have an idea to fix this please ?
To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.
To install OpenSSL development package on Debian, Ubuntu or their derivatives:
$ sudo apt-get install libssl-dev
To install OpenSSL development package on Fedora, CentOS or RHEL:
$ sudo yum install openssl-devel
Edit :
As #isapir has pointed out, for Fedora version>=22 use the DNF package manager :
dnf install openssl-devel
For Alpine Linux:
apk add openssl-dev
On CYGwin, you can install this as a typical package in the first screen. Look for
libssl-devel
for resolving this issue install:
# yum install openssl openssl-devel
and then try again to do make bzImage.
my setup,
am using virtual box vm for installation of weblogic server fmw_12.2.1.1.0_wls.jar on top of Ubuntu 16.04 server
installed oracle java using
sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
now java is installed in /usr/lib/jvm/java-8-oracle/jre/bin/java and i have set java_home = /usr/lib/jvm/java-8-oracle
have placed the file fmw_12.2.1.1.0_wls.jar in /usr/lib/jvm/java-8-oracle
when trying to install weblogic server from /usr/lib/jvm/java-8-oracle using java -jar fmw_12.2.1.1.0_wls.jar it fails with the error message as
preparing to launch the oracle universal installer from /tmp/OralInstall2016
Exception in thread "main" java.long.UnsatisifiedLinkError: /usr/lib/jvm/java-8-oracle/jrelib/amad64/libawt_xawt.so:libXender.so cannot open shared object file: no such file or directory
Please advise
You're missing pre-requisites. Perhaps there are more, but the one you're referred is because of missing X-Windows subsystem. Easiest just to invoke:
$ sudo apt install -y xterm

Introduction
I have a Web API writtten in python 3 and it uses flask. The code runs fine when I run the web API from the terminal and it is hosted from the following line in the code.
if __name__ == '__main__':
app.run(host='', port=8010, debug='true')
Current Situation
The code runs perfectly and I want to set it up on an Apache Server. However the Apache server already has websites that were built using python 2 and need mod_wsgi for python 2.
I looked up if there was a way to set up both mod-wsgi on the apache server but according to the following source you can't
mod_wsgi for Python 2 as well as Python 3 on one Apache server
Attempt at a solution
I 'm trying to install mod-wsgi into a virtual environment. I downloaded the package from here and tried to install it into the environment after activating it.
I ran sudo python setup.py install from the terminal but I got the error below
File "setup.py", line 139, in
'missing Apache httpd server packages.' % APXS)
RuntimeError: The 'apxs' command appears not to be installed or is not executable. Please check the list of prerequisites in the documentation for this package and install any missing Apache httpd server packages.
So I opened the Read Me file that was part of zipped package and found the following
If you wish to use a version of Apache which is installed into a non
standard location, you can set and export the APXS environment
variable to the location of the Apache apxs script for your Apache
installation before performing the installation.
Note that nothing will be copied into your Apache installation at this
point. As a result, you do not need to run this as the root user
unless installing it into a site wide Python installation rather than
a Python virtual environment.
To verify that the installation was successful, run the
mod_wsgi-express script with the start-server command::
mod_wsgi-express start-server
It seems to tackle my situation since Apache is not installed in the virtual environment that I'm running the command from but I have no idea how to do it
I presume they are talking about the setup.py file and that I should change the path but I do not know how to do it syntax wise or where my APXS script is located.
Here is snippet of the code that I think needs to be modified
APXS = os.environ.get('APXS')
WITH_HTTPD_PACKAGE = False
if APXS is None:
APXS = find_program(['mod_wsgi-apxs'],
paths=[os.path.dirname(sys.executable)])
if APXS is not None:
WITH_HTTPD_PACKAGE = True
if APXS is None:
APXS = find_program(['mod_wsgi-apxs', 'apxs2', 'apxs'],
'apxs', ['/usr/sbin', os.getcwd()])
elif not os.path.isabs(APXS):
APXS = find_program([APXS], APXS, ['/usr/sbin', os.getcwd()])
if not WITH_TARBALL_PACKAGE:
if not os.path.isabs(APXS) or not os.access(APXS, os.X_OK):
raise RuntimeError('The %r command appears not to be installed or '
'is not executable. Please check the list of prerequisites '
'in the documentation for this package and install any '
'missing Apache httpd server packages.' % APXS)
The Question
I'm doing all of this on a server running Ubuntu 12.04LTS if it helps. My question at the end are the following
Where is the APXS located usually in Ubuntu
How do I change the code snippet to make use the APXS script there
Thank you so much for Your time
Sorry for the inconvenience
Turns out I forgot to install APXS on my apache server. I simply ran the code from the terminal and it worked
sudo apt-get apache2-threaded-dev
Update
For Ubuntu 18 its (thank you #MagicLAMP)
sudo apt-get install apache2-dev
For Centos 7: (thank you #User)
yum install httpd-devel
For Centos 7:
yum install httpd-devel
I'd like to build packages using a build system (i.e. jenkins, travis, etc) but all I have are Ubuntu 12.04 VMs.
I've found this [1] instructions but mach does not support CentOS 7.0.
[1] http://blog.burghardt.pl/2008/12/how-to-build-rpm-packages-in-centos-chroot-on-debian/
http://mojo.codehaus.org/rpm-maven-plugin/ <- rpm plugin for the maven build system
sudo apt-get install rpm # for Ubuntu
Check out the command that it installs called rpmbuild.
Found it! There is actually a tool called rinse: "Rinse is a simple tool which is designed to carry out the installation of a new RPM-based distribution".
rinse --distribution="centos-7" --directory="/tmp/centos-7"

There are a lot of guides out there about setup php-fpm for Apache on CentOS 5x or 6x but none of them are working on Centos 7. I searched for days but can't find any solution.
yum install php-fpm
This command succesfully working.
But then i stuck with this line:
yum install mod_fastcgi
The error is "There is no package as mod_fastcgi"
Is there any mod_fastcgi module compatible with CentOS 7? If so, how can i complete php-fpm setup? Please guide me.
My server have some trouble about memory usage. So i have to optimize Apache. Here is my "top" result.
Deploy PHP with FastCGI
If you are using PHP code with your application, you will need to implement “PHP-FastCGI” in order to allow Nginx to properly handle and parse PHP code. You can install this via YUM from the EPEL repository that was previously installed:
yum install php-cli php spawn-fcgi
