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 Installing MySQL 5.0
To install MySQL, we do 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
mysqladmin -u root password yourrootsqlpassword
mysqladmin -h server1.example.com -u root password yourrootsqlpassword
to set a password for the user root (otherwise anybody can access your MySQL database!).
3 Installing Apache2
Apache2 is available as a CentOS package, therefore we can install it like this:
yum install httpd
Now configure your system to start Apache at boot time…
chkconfig –levels 235 httpd on
… and start Apache:
Now direct your browser to http://192.168.0.100, and you should see the Apache2 placeholder page:
Apache’s default document root is /var/www/html on CentOS, and the configuration file is /etc/httpd/conf/httpd.conf. Additional configurations are stored in the /etc/httpd/conf.d/ directory.
4 Installing PHP5
We can install PHP5 and the Apache PHP5 module as follows:
yum install php
We must restart Apache afterwards:
