Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'解决

安装上mysql后，报 Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'，试了网上的方法都没有用，于是打开/etc/my.cnf查看。

看到这么一段：

# The MySQL server

 26 [mysqld]

 27 port            = 3306

 28 socket          = /tmp/mysql.sock

 29 skip-external-locking

 30 log-error=/alidata/log/mysql/error.log

 31 key_buffer_size = 16M

 32 max_allowed_packet = 1M

 33 table_open_cache = 64

 34 sort_buffer_size = 512K

 35 net_buffer_length = 8K

 36 read_buffer_size = 256K

 37 read_rnd_buffer_size = 512K

 38 myisam_sort_buffer_size = 8M

可知，使用的.sock文件，是/tmp/mysql.sock，而不是/var/run/mysqld/mysqld.sock，于是加个链接

     ln -s /tmp/mysql.sock /var/run/mysqld/mysqld.sock

问题解决
