Can't connect to local MySQL through socket '/tmp/mysql.sock'解决方法(小编内容)

报错信息：

ERROR 2002: Can't connect to local MySQL server through socket ‘/tmp/mysql.sock' (111)

解决办法：

/usr/local/mysql/bin/mysqladmin -u root > -S /var/lib/mysql/mysql.sock password 'your.passwd'

或者做个软连接

ln -s /var/lib/mysql/mysql.sock /tmp

原因：

其实提示找不到 /tmp/mysql.sock有时也并不是/tmp目录下没这个文件，是启动命令不对。

/usr/local/mysql/bin/mysql -u root -p
/usr/local/mysql/bin/mysqld --user=mysql&
/usr/local/mysql/bin/mysqld --user=root&
/usr/local/mysql/bin/mysqld_safe --user=root&
/usr/local/mysql/bin/mysqld_safe --user=mysql&
/usr/local/mysql/bin/safe_mysqld--uer=root&(注意safe_mysqld与mysqld_safe是不同的，&表示mysql在后台运行)

报错信息：

STOPPING server from pid file /usr/local/mysql/data/localhost.localdomain.pid 060304 11:46:21 mysqld ended

解决办法：

这是权限问题，我的mysql目录属于root用户，也属于root群组，改用mysqld_safe启动就没问题了，大家只要注意这几个mysql,safe_mysqld,mysqld_safe,mysqld,mysqladmin.多试几次,其实有时mysql已经正常启动了，查看mysql是否启动命令

ps -aux | grep mysqld

会看到如下类似内容

mysql 6394 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/mysql 6395 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/mysql 6396 0.0 1.5 10528 992 pts/3 S 16:16 0:00
/usr/local/mysql/root 6422 0.0 1.1 2408 732 pts/3 S 16:20 0:00 grep mysql

查看mysql是否在监听端口命令
