解决 MySQL manager or server PID file could not be found! 的方法

  # service mysqld stop
  MySQL manager or server PID file could not be found!      
  解决办法:
  首先查看一下进程
  # ps aux |grep mysq*
  root      26430.00.2   45361224 ?      S    01:09   0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/var --pid-file=/usr/local/mysql/var/centos.pid
  mysql   27570.01.2369766608 ?      Sl   01:09   0:00 /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --user=mysql --log-error=/usr/local/mysql/var/centos.err --pid-file=/usr/local/mysql/var/centos.pid --socket=/tmp/mysql.sock --port=3306
  root      47880.00.1   3920   684 pts/2    R+   11:11   0:00 grep mysq*
  如果看到上面的内容,那说明,Mysql的进程卡死了,这时用就要把这些卡死的进程都关闭
  # kill 2643
  # kill 2757
  启动Mysql 就ok了
  # service mysqld start
  Starting MySQL.
