ERROR! MySQL is
running but PID
file
could not be
found ?
出现这个问题原因很多
最常见的通常是PID进程未全部关闭
比如启动safe
mysqld进程后
未关闭
运行 /etc/init.d/mysql
status
会提示
ERROR! MySQL is running but PID file could not be found
先打印MYSQL进程
ps aux | grep mysql
然后KILL进程
kill -9 pid1 pid2 …
在启动MYSQL
/etc/init.d/mysql start
在检查
/etc/init.d/mysql status
SUCCESS! MySQL running (10021)
这个只是其中一个原因
还有其他的 大部分的错误可以在日志里查看到
Centos mysql的日志
在/var/lib/mysql/主机头名称xxx.err
running but PID
file
could not be
found ?
