MySQL-server-5.5.36-1.rhel5.x86_64.rpm
MySQL-client-5.5.36-1.rhel5.x86_64.rpm
[root@dev ~]# mkdir /soft/MySQL-5.5.36
把安装文件上传至此目录
添加mysql组
[root@dev ~]# groupadd mysql
添加mysql用户
[root@dev ~]# useradd -g mysql mysql
[root@dev ~]# chown -R mysql /soft/MySQL-5.5.36
[root@dev ~]# su - mysql
[mysql@dev ~]$ cd /soft/MySQL-5.5.36
[mysql@dev MySQL-5.5.36]$ tar -xvf MySQL-5.5.36-1.rhel5.x86_64.rpm-bundle.tar
MySQL-client-5.5.36-1.rhel5.x86_64.rpm
MySQL-devel-5.5.36-1.rhel5.x86_64.rpm
MySQL-server-5.5.36-1.rhel5.x86_64.rpm
MySQL-shared-5.5.36-1.rhel5.x86_64.rpm

MySQL-embedded-5.5.36-1.rhel5.x86_64.rpm
MySQL-shared-compat-5.5.36-1.rhel5.x86_64.rpm
[mysql@dev MySQL-5.5.36]$ chmod u+x MySQL-server-5.5.36-1.rhel5.x86_64.rpm
[mysql@dev MySQL-5.5.36]$ chmod u+x MySQL-client-5.5.36-1.rhel5.x86_64.rpm
安装服务器端
非root用户使用rpm可以采用 sudo 命令 的方式，sudo 需要配置
[mysql@dev MySQL-5.5.36]$ sudo rpm -ivh MySQL-server-5.5.36-1.rhel5.x86_64.rpm

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h dev password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.

修改root用户密码
[mysql@dev MySQL-5.5.36]$ mysqladmin -u root password "password"
[mysql@dev MySQL-5.5.36]$ mysql -u root -p
Enter password:输入密码
mysql> use mysql
mysql> select host,user,password from user;

设置root用户可以远程连接，
此语句会在user表插一条记录
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
#另一种方法，修改原有的记录
#mysql> UPDATE user SET Host='%' WHERE User='root' AND Host='localhost' LIMIT 1;
mysql> select host,user,password from user;
