遇到了以上无法启动的问题,查看了以下mysql的进程,发现进程还在
kill一下试试
[root@110 db]# ps -ef | grep mysql root 7092 1 0 03:31 ? 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/db/data --pid-file=/db/data/110.pid mysql 7269 7092 0 03:31 ? 00:00:01 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/db/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/var/log/mysqld.log --pid-file=/db/data/110.pid --socket=/tmp/mysqld.sock root 9131 7654 0 05:00 pts/0 00:00:00 grep --color=auto mysql
[root@110 db]# kill -9 7092 [root@110 db]# [root@110 db]# ps -ef | grep mysql mysql 7269 1 0 03:31 ? 00:00:01 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/db/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/var/log/mysqld.log --pid-file=/db/data/110.pid --socket=/tmp/mysqld.sock root 9133 7654 0 05:00 pts/0 00:00:00 grep --color=auto mysql
再次查看,发现还有,继续kill
[root@110 db]# kill -9 7269 [root@110 db]# ps -ef | grep mysql root 9149 7654 0 05:01 pts/0 00:00:00 grep --color=auto mysql [root@110 db]#
没有了,启动mysql试一下
