Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On CentOS 6.4
Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 6.4 server with PHP5 support (through PHP-FPM) and MySQL support.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.
2 Enabling Additional Repositories
php-fpm is not available from the official CentOS repositories, but from the Remi RPM repository which itself depends on the EPEL repository; we can enable both repositories as follows:
rpm --import https://fedoraproject.org/static/0608B895.txt
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm --import http://rpms.famillecollet.com/RPM-GPG-KEY-remi
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
yum install yum-priorities
... and add the line priority=10 to the [epel] section:
[epel] name=Extra Packages for Enterprise Linux 6 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 priority=10 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 [...]
Then do the same for the [remi] section in /etc/yum.repos.d/remi.repo, plus change enabled to 1:
[remi] name=Les RPM de remi pour Enterprise Linux $releasever - $basearch #baseurl=http://rpms.famillecollet.com/enterprise/$releasever/remi/$basearch/ mirrorlist=http://rpms.famillecollet.com/enterprise/$releasever/remi/mirror enabled=1 priority=10 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi failovermethod=priority [remi-test] name=Les RPM de remi en test pour Enterprise Linux $releasever - $basearch #baseurl=http://rpms.famillecollet.com/enterprise/$releasever/test/$basearch/ mirrorlist=http://rpms.famillecollet.com/enterprise/$releasever/test/mirror enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
3 Installing MySQL 5
First we install MySQL 5 like this:
yum install mysql mysql-server
Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:
chkconfig --levels 235 mysqld on
Now check that networking is enabled. Run
netstat -tap | grep mysql
It should show something like this:
[[email protected] ~]# netstat -tap | grep mysql
tcp 0 0 *:mysql *:* LISTEN 1799/mysqld
[[email protected] ~]#
If it does not, edit /etc/my.cnf and comment out the option skip-networking:
[...] #skip-networking [...]
and restart your MySQL server:
to set a password for the user root (otherwise anybody can access your MySQL database!):
[[email protected] ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): <-- ENTER
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] <-- ENTER
New password: <-- yourrootsqlpassword
Re-enter new password: <-- yourrootsqlpassword
Password updated successfully!
Reloading privilege tables..
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
Remove anonymous users? [Y/n] <-- ENTER
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] <-- ENTER
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] <-- ENTER
- Dropping test database...
- Removing privileges on test database...
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] <-- ENTER
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!

4 Installing Nginx
Nginx is available as a package for CentOS 6.4 (from EPEL) which we can install as follows:
yum install nginx
Then we create the system startup links for nginx and start it:
chkconfig --levels 235 nginx on
Type in your web server's IP address or hostname into a browser (e.g. http://192.168.0.100), and you should see the nginx welcome page:
