查看错误日志
情景1:
110206 12:58:35 [ERROR] Can't start server : Bind on unix socket: No such file or directory
110206 12:58:35 [ERROR] Do you already have another mysqld server running on socket: /mysql/mysqldir/data/mysql.sock ?
110206 12:58:35 [ERROR] Aborting
于是ps -ef | grep mysql 一把.未发现有mysqld.
netstat -an | grep 3306 一把.也未发现异常.
最后从mysql安装目录下重新复制一个配置文件到/etc/my.cnf
修改相应参数,解决问题。
情景2:
/mysql/mysqldir/bin/mysqld: Table 'mysql.plugin' doesn't exist
[ERROR] Can't open the mysql.plugin table. Please run my sql_upgrade to create it.
原因:编译安装后忘记初始化表。
解决:运行mysql_install_db 。
