Can ' t connect to local MySQL server through socket '/var/lib/mysql/mysql.socket

First, solve Var/run/mysqld no PID and sock files

MySQL Mysql.sock lost because of the cause of the loss is generally due to inconsistent configuration files, mysqld error starts, Mysqld_safe will clear the mysql.sock. The workaround is to:

It is not possible to create/tmp/mysql.sock and hostname.pid files because the normal person does not switch to the MySQL user when resolving the failure, causing permissions problems and unable to create the MySQL authorization table. Therefore, the summary solution is as follows:

#su mysql//root user is also possible

$/usr/local/bin/mysql_install_db//To Bin directory execution, rebuild authorization form

$/usr/local/bin/mysqld_safe &

MYSQL-UROOT-P//test

mysq>bye;

$

Files have been resolved to regenerate new/tmp/mysql.sock and Hostname.pid

var/

$SU Root

Second, resolve the Mysql.sock file path is not correct

1. Create a link:ln-s/var/lib/mysql/mysql.sock/path/to/mysql/mysql.sock in/var/lib/mysql

2. Under root permissions, modify the My.cnf file (/etc/mysql/my.cnf) to specify the correct path

Either 3.1 and 2 can be selected
