ubuntu环境下重启mysql服务报错“No directory, logging in with HOME=-”

前提:使用系统的环境

3.13.0-24-generic

mysql的版本:5.6.33

错误描述:

首先用mysqld_safe启动报错如下:

root@zabbix-forFunction:~# mysqld_safe

170425 01:56:52 mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take effect.

170425 01:56:52 mysqld_safe Logging to '/var/log/mysql/error.log'.

170425 01:56:52 mysqld_safe A mysqld process already exists

root@zabbix-forFunction:~# ps -aux | grep mysql

mysql 1472 0.1 15.5 1752260 625824 ? Ssl Apr24 1:16 /usr/sbin/mysqld

root 10160 0.0 0.0 15952 920 pts/3 S+ 01:59 0:00 grep --color=auto mysql

这个时候使用/etc/init.d/mysql stop停止点mysql服务发现mysql的进程还是存在,这个时候需要使用如下命令来停止进程:

root@zabbix-forFunction:~# sudo service mysql stop

mysql stop/waiting

root@zabbix-forFunction:~# ps -aux | grep mysql

root 13531 0.0 0.0 15948 920 pts/3 S+ 02:15 0:00 grep --color=auto mysql

使用usermod命令来重新定位mysql所在的目录:

root@zabbix-forFunction:~# sudo usermod -d /var/lib/mysql/ mysql

1

然后再重新启动mysql服务:

root@zabbix-forFunction:~# sudo service mysql start

mysql start/running, process 13597
