今天无事看到自己的主机名不对,于是改了一下,以便区分服务器,那只重启mysql时出现下面错误:
MySQL manager or server PID file could not be found! [FAILED]
Starting MySQL.Manager of pid-file quit without updating fi[FAILED]
怎么会找不到PID呢,看下面:
[root@daban114.com ~]# ps aux | grep mysql
mysql 16433 0.0 0.2 36636 5756 ? Sl 15:07 0:00 /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --user=mysql --log-error=/usr/local/mysql/var/hao9goAndSecondWeb.err --pid-file=/usr/local/mysql/var/hao9goAndSecondWeb.pid --socket=/tmp/mysql.sock --port=3306
root 16992 0.0 0.0 4020 704 pts/0 S+ 15:11 0:00 grep mysql
原来PID还是原来主机名.pid,运行:
kill -9 <mysqlpid> 然后 service mysql start 哈哈看到绿色的OK了,
[root@daban114 ~]# service mysql start
Starting MySQL. [ OK ]
