More often you receive Too many connections error when you attempt to connect MySQL server. This error is self explanatory and tells that all available connections are being used by other clients. If you want to allow more simultaneous connections to MySQL database, you may need to tweak max_user_connections settings in my.cnf file. Following article will instruct you how to increase MySQL connections.

 

NOTE: Following instructions are only applicable to VPS and Dedicated server users. Furthermore, you will need root access to modify my.conf file. 

 

  1. Login to your Linux machine via SSH.

  2. Edit my.cnf file using your choice of editor like vi, nano, vim or pico.

    vi /etc/my.cnf
  3. Locate the setting similar to below.

    [mysqld]
    local-infile=0
    datadir=/var/lib/mysql
    user=mysql
    symbolic-links=0
    max_user_connections = 20
  4. Change the value of max_user_connections to your required level. For example, we want to set maximum connection value to 50.
