解决MySQL --Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘

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

解决方案

find / -name mysql.sock

将/tmp/mysql.sock文件重新与/var/lib/mysql/mysql.sock文件创建软链接关联

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

重新登录即可
