Detaillierte Einführung in die Linux-MySQL-Installation und -Wartung

rpm -qa | grep mysql

   rpm -e mysql　　// 普通删除模式
 rpm -e --nodeps mysql　　// 强力删除模式，如果使用上面命令删除时，提示有依赖的其它文件，则用该命令可以对其进行强力删除

                     yum list | grep mysql

                    yum install  -y  mysql-server  mysql  mysql-deve

                     rpm -qi mysql-server

 service mysqld start            
 如果命令启动不了：mysql: unrecognized service            
 使用：    /etc/rc.d/init.d/mysqld start            
 修改启动文件权限   chmod 755 /etc/rc.d/init.d/mysqld
 再次启动：service mysqld start

chkconfig --list | grep mysqld

chkconfig mysqld on

  /usr/bin/mysqladmin -u root password 'new-password'

mysqladmin -u root password 'root'
