mysql启动失败

/var/log/mysqld.log日志以下：

161102 23:02:43 [ERROR] Can't start server: Bind on TCP/IP port: Cannot assign requested address
161102 23:02:43 [ERROR] Do you already have another mysqld server running on port: 3306 ?
161102 23:02:43 [ERROR] Aborting

161102 23:02:43  InnoDB: Starting shutdown...
161102 23:02:48  InnoDB: Shutdown completed; log sequence number 0 99114095
161102 23:02:48 [Note] /usr/libexec/mysqld: Shutdown complete

网上已有好多缘由，这里提供另一种可能出错的缘由：

my.cnf里配置了bind-address，且bind-address链接失败，也会报端口被占用的错误。
