[root@ rhel5 mysql-5.5.10]#make
[root@ rhel5 mysql-5.5.10]#make install

[root@ rhel5~]# cd /usr/local/mysql

[root@ rhel5 mysql]# chown -R root:mysql .　//把当前目录中所有文件的所有者所有者设为root，所属组为mysql

[root@ rhel5 mysql]# chown -R mysql:mysql data

[root@ rhel5 mysql]# cp support-files/my-medium.cnf /etc/my.cnf　//将mysql的启动服务添加到系统服务中

[root@ rhel5 mysql]# cd /usr/local/mysql
[root@ rhel5 mysql]# scripts/mysql_install_db --user=mysql

[root@ rhel5~]# vi /root/.bash_profile

在PATH=$PATH:$HOME/bin添加参数为：

PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib

[root@ rhel5~]#source /root/.bash_profile

[root@ rhel5~]# cd /usr/local/mysql

[root@ rhel5 mysql]# ./bin/mysqld_safe --user=mysql & 　 //启动MySQL，但不能停止

启动日志写在此文件下：/usr/local/mysql/data/localhost.err

关闭MySQL服务

[root@ rhel5 mysql]# mysqladmin -u root -p shutdown　　//这里MySQL的root用户还没有配置密码，所以为空值。需要输入密码时，直接点回车键即可。

[root@ rhel5~]# service mysql.server start  
[root@ rhel5~]# service mysql.server stop
[root@ rhel5~]# service mysql.server restart

[root@ rhel5 mysql]# cp support-files/mysql.server  /etc/init.d/mysql　//将mysql的启动服务添加到系统服务中

[root@ rhel5~]# mysql -u root mysql

mysql>use mysql;
mysql>desc user;
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";　　//为root添加远程连接的能力。
mysql>update user set Password = password('xxxxxx') where User='root';
mysql>select Host,User,Password  from user where User='root'; 
mysql>flush privileges;
mysql>exit

重新登录：mysql -u root -p

若还不能进行远程连接，则关闭防火墙
[root@ rhel5~]# /etc/rc.d/init.d/iptables stop
