Upgrade Apache 2.4.6 to 2.4.29 without losing config

Apache is the most widely used web server software for serving web applications and it is essential part of any server. To have the latest version installed, means that your software package will probably have more new features and known bugs fixes.

Introduction

In this tutorial I am going to describe simple steps to install the latest Apache (httpd) version on your Centos 7 system.

By default Centos 7 has few predefined repositories for installing packages, but unfortunately a lot of packages are out of date there.

Step 1 — Find out the Apache version in default repos

In order to check the current version of httpd package available in repositories – type the following command:

1	yum info httpd

If you have default installation, you will most likely see similar output.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

[root@crosp ~]# yum info httpd Loaded plugins: fastestmirror epel/x86_64/metalink | 19 kB 00:00 epel | 4.3 kB 00:00 (1/3): epel/x86_64/group_gz | 170 kB 00:00 (2/3): epel/x86_64/primary_db | 4.6 MB 00:00 (3/3): epel/x86_64/updateinfo | 780 kB 00:00 Loading mirror speeds from cached hostfile * base: mirrors.ircam.fr * epel: mirrors.ircam.fr * extras: centos.mirror.fr.planethoster.net * updates: centos.mirror.fr.planethoster.net Available Packages Name : httpd Arch : x86_64 Version : 2.4.6 Release : 45.el7.centos.4 Size : 2.7 M Repo : updates/7/x86_64 Summary : Apache HTTP Server URL : http://httpd.apache.org/ License : ASL 2.0 Description : The Apache HTTP Server is a powerful, efficient, and extensible : web server.

As you can see from the output above, there is only 2.4.6 Apache version available in default repos.

Please note:

Centos uses Security Backporting Practice in order to apply most recent fixes to older versions of a software package, as a result it doesn’t mean that an older version provided by default repositories is vulnerable. But in my case I didn’t have a required update.

You can see a changelog using these commands :

1 2	sudo yum install yum-changelog yum changelog httpd

Step 2 — Set up CodeIT repositories

There is a great custom repo created by these guys CodeIT It provides latest versions of web servers (Apache & Nginx).

Before setting up the CodeIT repository first of all you need to enable the EPEL. It satisfies some dependencies required by the CodeIT repo.

1	sudo yum install -y epel-release

Finally enable the CodeIT repository.

1	cd /etc/yum.repos.d && wget https://repo.codeit.guru/codeit.el7.repo

Then verify the Apache package version again and you should see something like that.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

[root@crosp ~]# yum info httpd Loaded plugins: changelog, fastestmirror Loading mirror speeds from cached hostfile * base: centos.crazyfrogs.org * epel: mirror.23media.de * extras: mirrors.ircam.fr * updates: centos.mirror.fr.planethoster.net Available Packages Name : httpd Arch : x86_64 Version : 2.4.29 Release : 3.el7.codeit Size : 1.4 M Repo : CodeIT/x86_64 Summary : Apache HTTP Server URL : http://httpd.apache.org/ License : ASL 2.0 Description : The Apache HTTP Server is a powerful, efficient, and extensible : web server.

Step 3 — Update the Apache web-server

Now you should have everything set up and upgrade to the latest Apache package.

1	yum upgrade httpd

Once Apache is installed, let’s start, restart or check the status of it and test whether it is working.

1	[root@crosp ~]# systemctl start httpd

Finally, tell systemd to start the Apache service automatically at boot.

1	[root@crosp ~]# systemctl enable httpd

That’s all, if you have any troubles please feel free to leave comments below.
