Solution of Exception Error ERROR: 2002 in mysql

Recently, an error was reported when starting mysql, and the error prompt is as follows:

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

Checking process

1. Check first /etc/rc.d/init.d/mysqld status See if mysql has started.

In addition, see if it is a permission problem.

2. Determine if your mysql. sock is in that position,

mysql -u  Yours mysql User name  -p -S /var/lib/mysql/mysql.sock

3. Try: service mysqld start

4. If it is a permission problem, change the permission first #chown -R mysql:mysql /var/lib/mysql

[root@localhost ~]# /etc/init.d/mysqld start
 Start  MySQL :  [  Determine  ]
[root@localhost ~]# mysql -u root -p

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

The reason is,/var/lib/mysql access issues.

shell> chown -R mysql:mysql /var/lib/mysql

Then start the server

shell> /etc/init.d/mysql start

View/var/lib/mysql will automatically generate the mysql. sock file after the server starts normally.

But my problem is still unsolved.

The problem is finally solved:

Method: Modification/etc/my. conf:

[mysqld]
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock

[mysql.server]
user=mysql
basedir=/usr/local/mysql

If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:

[client]
socket=/var/lib/mysql/mysql.sock

Discover that it is still the same, run /etc/init.d/mysql start Error: Starting MySQLCouldn 't find MySQL manager or server is mysqld service not started, running /usr/local/mysql/bin/mysqld_safe &

Problem solving.
