一、卸载原来的mysql:

卸载一:
输入:
#rpm -qa | grep -i mysql
显示:
mysql-libs-5.1.52-1.el6_0.1.i686
卸载方法:
yum -y remove mysql-libs-5.1.52-1.el6_0.1.i686
 
卸载二:
输入:
#rpm -qa | grep -i mysql
显示:
MySQL-client-5.1.62-1.glibc23.i386
MySQL-server-5.1.62-1.glibc23.i386
卸载方法:
#rpm -ev MySQL-client-5.1.62-1.glibc23.i386 MySQL-server-5.1.62-1.glibc23.i386
 
二、安装MySQL服务器端:
安装文件:MySQL-server-5.1.62-1.glibc23.i386.rpm
# rpm -ivh /software/mysql/MySQL-server-5.1.62-1.glibc23.i386.rpm
这是在/usr/share/mysql 目录下生成一些 文件,其中有一个文件名为:my-medium.cnf 将其拷贝到/etc/my.cnf中
# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
现在就安装完了,可以看看他运行的进程:
# ps -ef | grep mysql
 
三、安装MySQL客户端:
# rpm -ivh /software/mysql/MySQL-client-5.1.62-1.glibc23.i386.rpm
现在就安装客户端成功了,可以看看关于MySQL一些文件:
# ls /usr/bin/mysql*
 
四、登录mysql:
刚开始装上mysql时是没有密码的,输入:
# mysql
就可登录到mysql数据库上了。
 
五、设置MySQL密码:
# mysqladmin -u root password 123456
这样就将mysql中用户名为root密码设为123456
 
六、登录设置有密码的mysql:
命令和dos下登录mysql是一样的:
# mysql -uroot -p123456
或者
# mysql -uroot -p[回车]
再输入密码
