How to Optimize MySQL

Nov 08

Today I found my websites were very slow. Log into linode system and I found MySQL is over 500% CPU usage.

Just google it. and found a script.

  1. wget
  2. use winscp to change the pl file to 777
  3. use putty to telnet the server.
  4. Just run the pl. ./
  5. The pl will display some setting suggestion.  change ./etc/mysql/my.cnf
  6. Use the following command to optimize database tables
    mysqlcheck –optimize -A -u username -ppassword
  7. service mysql restart
  8. That’s all.
