Install Nginx + PHP-FPM + MySQL on Low-end CentOS server

There are many good low-end VPS provider over there with low cost, such as RamNode providing $2/month for their 128mb VPS, so the question is how can we do on a low-end CentOS server? Well, the answer is: you can run many websites on it with some tweak configurations. Let’s discover how to do this.

On CentOS 5

Run

wget http://freevps.us/downloads/nginx-centos.sh -O - |bash

OR

wget http://www.comfortvps.com/script/shell/nginx/nginx-php-mysql.sh -O - |bash

On CentOS 6

Run

yum -y install wget --noplugins
wget freevps.us/downloads/nginx-centos-6.sh -O - |bash

Troubleshooting

There might be some problems after the installing.

• If mysqld service cannot start due to the bug of no mysql user, run the post-installation scripts as follows: 

  groupadd -g 89 mysql &>/dev/null
  useradd -u 89 -g mysql -d /var/lib/mysql -s /bin/false mysql &>/dev/null
  /usr/bin/mysql_install_db --user=mysql --basedir=/usr
  chown -R mysql:mysql var/lib/mysql &>/dev/null

• If you cannot access mysql due to root password, remember to reset mysql root password.

Well, finally, this is my server status after these installations
