Mysql彻底删除Mysql重新安装

 

1、删除 mysql

 

1 sudo apt-get autoremove --purge mysql-server-5.0

2 sudo apt-get remove mysql-server

3 sudo apt-get autoremove mysql-server

4 sudo apt-get remove mysql-common (非常重要)

上面的其实有一些是多余的,建议还是按照顺序执行一遍

 

清理残留数据

 

dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

2、安装 mysql

 

1 sudo apt-get install mysql-server

2 sudo apt-get install mysql-client

3 sudo apt-get install php5-mysql(安装php5-mysql 是将php和mysql连接起来 ) 

 

一旦安装完成,MySQL 服务器应该自动启动。您可以在终端提示符后运行以下命令来检查 MySQL 服务器是否正在运行:

 

1 sudo netstat -tap | grep mysql

 

当您运行该命令时,您可以看到类似下面的行:

 

tcp 0 0 localhost.localdomain:mysql *:* LISTEN -

如果服务器不能正常运行,您可以通过下列命令启动它:

 

1 sudo /etc/init.d/mysql restart

 

3、进入mysql

 

$mysql -uroot -p 管理员密码

配置 MySQL 的管理员密码:

 

1 sudo mysqladmin -u root password newpassword
