[root@centos var]# service mysqld stopmysql
MySQL manager or server PID file could not be found! [FAILED]
解決辦法:
首先查看一下進程
[root@
irxpert-test
/]# ps aux |grep mysq*
root
10274 0.0 0.0 68160 1336 ? S 13:43 0:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/irxpert-test.pid
mysql
10353 0.0 1.0 344360 39464 ? Sl 13:43 0:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/irxpert-test.err --pid-file=/var/lib/mysql/irxpert-test.pid
root 11884 0.0 0.0 63384 760 pts/1 S+ 15:44 0:00 grep mysq*
若是看到上面的內容,那說明,Mysql的進程卡死了,這時用就要把這些卡死的進程都關閉
[root@centos mysql]# kill
10274
[root@centos mysql]# kill
10353
啓動Mysql就ok了
[root@centos mysql]# service mysql start
Starting MySQL. [ OK ]
