Can't connect to local MySQL server through socket解决方法
?
最近我的ubuntu系统sudo装的
数据库出现问题，迫于无奈重装，重装启动后用mysql命令客户端连接，出现如下提示：
Ruby代码 ??
[LING mysql]$ mysql -u root -p ?
??
Enter password: ??
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) ?
?
?我的my.cnf如下：
Python代码 ??
[mysqld] ?
datadir=/var/lib/mysql ?
socket=/var/lib/mysql/mysql.sock ?
??
user=mysql ?
# Default to using old password format for compatibility with mysql 3.x ?
# clients (those using the mysqlclient10 compatibility package). ?
old_passwords=1 ?
?www.2cto.com ?
[mysqld_safe] ?
log-error=/var/log/mysqld.log ?
pid-file=/var/run/mysqld/mysqld.pid ?
port=3307 ?
?
?进入/var/lib/mysql下，发现mysql.sock存在，但/var/run/mysqld下没有mysqld.sock，灵机一动，可以通过软链接的方式使用/var/lib/mysql/mysql.sock：
Shell代码 ??
[ROOT mysqld]$ ln -s /var/lib/mysql/mysql.sock /var/run/mysqld/mysqld.sock ?
??
[ROOT mysqld]$ mysqld_safe --log-error=/var/lib/mysql/error.log & ?
?做链接并启动mysql，查看error.log，如下：
Java代码 ? ? www.2cto.com ?
[ROOT
mysql]$ more error.log ?
??

?重新链接，成功了！
