修改linux主机名导致mysql启动失败

时间:2021-04-14 13:47:10

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  ]
