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 [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 [ROOT mysql]$ more error.log InnoDB: The log sequence number in ibdata files does not match InnoDB: the log sequence number in the ib_logfiles! 100313 10:48:12 InnoDB: Database was not shut down normally! InnoDB: Starting crash recovery. InnoDB: Reading tablespace information from the .ibd files... InnoDB: Restoring possible half-written data pages from the doublewrite InnoDB: buffer... 100313 10:48:12 InnoDB: Started; log sequence number 0 43655 100313 10:48:12 [Note] /usr/sbin/mysqld: ready for connections. Version: '5.0.51a-3ubuntu5.5' socket: '/var/lib/mysql/mysql.sock' port: 3307 (Ubuntu) [ROOT mysql]$ 重新链接，成功了！
