Supervisor 监控 Mysql 无法自动启动~~

VPS经常因为Mysql，apahce 2G内存满而导致Mysql经常挂~~
经常出现Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)这个问题 ~~

每次都需要手动service mysql restart 重启。。但问题隔两天三后又出现……甚是烦人~

装了Supervisor 监控，手动Kill all mysql 可以自动启动进程，但当上面的问题出现后，确无法自动启动？这么坑爹的问题，折腾了我好久好久~~~
