ubuntu下启动mysql服务出现The server quit without..问题

 

这个错误是如何产生的呢?

 

启动mysql 为什么会报 The server quit without updating PID file(....pid )

 

产生的原因有几种,

 

1:配置文件出现错误my.cnf 

 

2:/usr/local/mysql/data  文件夹 的权限问题

 

3:进程已存在 mysql  的服务

 

首先 说说楼主的遭遇, 由于

 

配置 mysql 默认编码格式的时候出现配置错误,导致启动mysql (后来才想起来 我改过配置文件了)

 

 The server quit without updating PID file(updat file  .....pid )

 

悲催的折腾到2点多,google 查各种资料..于是便有了上面几个总结

 

问题1 的解决:

 

由于我当时脑抽了估计,居然改/usr/local/mysql/my.cnf 配置文件,导致后来才发现这里改动过了,

 

但是mysql 启动的时候,我觉得应该是这样进行查找my.cnf 的

 

首先 /etc/my.cnf 是否存在

 

1if( true):2    读取/etc/my.cnf3else:4
Copy after login

读取/usr/local/mysql/my.cnf | /usr/local/mysql/my.cnf~

检查发现 my.cnf 没问题,于是问题1 忽略( 结果就是折腾到2点,忽略了/usr/local/mysql/my.cnf 的检查 )

问题2:

usr/local/mysql/data 权限的问题, 看当前登入用户是否具有写的权限. 这里要搞清楚 linux 群组与文件拥有者 权限的关系(不清楚? 鸟哥私房菜.)

问题3:

查看进程是否有 mysql 服务的进程,有的话 kill 掉

命令:

ps aux|grep mysql
Copy after login

    若存在, kill -9 相对应的 id(例如3871)

 

三个问题,解决.
