The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn how to solve the problem of ERROR 2002 (HY000) error reporting in MySQL.

[root@testmysql bin] #. / mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket'/ tmp/mysql.sock' (2)

Solution:

Because the default mysql.sock of mysql is / usr/local/mysql/data/mysql.sock, but the linux system always goes to / tmp/mysql.sock to find it, so it will report an error.

1. Specify the mysql channel directly

As far as I know (ps: I am a rookie, please correct), the old version is: / var/lib/mysql/mysql.sock

In the new version, the default is / usr/local/mysql/data/mysql.sock. Specifically, you can check the my.cnf file.

[root@testmysql bin] #. / mysql-socket=/usr/local/mysql/data/mysql.sock

two。 Create a symbolic connection:

Add soft connections to mysql.sock (equivalent to shortcuts in windows).

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

Eg:

Root@localhost ~] # mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket'/ tmp/mysql.sock' (2)

[root@testmysql bin] # ln-s / var/lib/mysql/mysql.sock / tmp/mysql.sock

Interlude: it is possible that you have the following situation when you establish a connection

[root@testmysql bin] # ln-vs / usr/local/mysql/data/mysql.sock / tmp/mysql.sock

Ln: creating symbolic link `/ tmp/mysql.sock': File exists

It doesn't matter, just add the-f parameter. The main process of-f: first delete the soft link dd with the same name, and then create a hard link dd

[root@testmysql bin] # ln-f / usr/local/mysql/data/mysql.sock / tmp/mysql.sock

[root@testmysql bin] #. / mysql
