mysql - 启动错误InnoDB: mmap(137363456 bytes) failed; errno 12

【zsm】下午mysql出现了问题,很纠结,最后找到了原因,原因是内存不够用;

查看内存显示  
[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
重启错误提示 
[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!

这个其实日志里面说的很明白就是 mysql要占用内存的时候 物理内存不够用导致的 所有 vim /etc/my.cnf
[inonodb]
innodb_buffer_pool_size=64MB  把这个数值改小 高版本的默认是128mb  版本的默认是8Mb
