mysql - 啓動錯誤InnoDB: mmap(137363456 bytes) failed; errno 12

【zsm】下午mysql出現了問題，很糾結，最後找到了緣由，緣由是內存不夠用；

查看內存顯示  

[root@AY1305070924544 /]# free -m

             total       used       free     shared    buffers     cached

Mem:           995        928         66          0          6         19

-/+ buffers/cache:        903         91

Swap:            0          0          0

重啓錯誤提示 

[root@AY1305070924544 /]# /etc/init.d/mysqld start

Starting MySQL. ERROR! The server quit without updating PID file (/var/mysql/data/AY1305070924544.pid).

[root@AY1305070924544 /]# /etc/init.d/mysqld restart

 ERROR! MySQL server PID file could not be found!

Starting MySQL. ERROR! The server quit without updating PID file (/var/mysql/data/AY1305070924544.pid).

這個其實日誌裏面說的很明白就是 mysql要佔用內存的時候 物理內存不夠用致使的 全部 vim /etc/my.cnf
