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！
