1、下载Mysql安装所需的rpm包
http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.linux_glibc2.5.x86_64.rpmhttp://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.linux_glibc2.5.x86_64.rpmhttp://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.linux_glibc2.5.x86_64.rpm
2、安装
[root@Luxh-01 softs]# rpm -ivh MySQL-server-5.6.21-1.linux_glibc2.5.x86_64.rpm
[root@Luxh-01 softs]# rpm -ivh MySQL-client-5.6.21-1.linux_glibc2.5.x86_64.rpm
[root@Luxh-01 softs]# rpm -ivh MySQL-devel-5.6.21-1.linux_glibc2.5.x86_64.rpm
安装过程中，Mysql会成一个随机密码给root用户，密码存储在 /root/.mysql_secret
MySQL安装目录信息：
| Directory | Contents of Directory |
|---|---|
/usr/bin | Client programs and scripts |
/usr/sbin | The mysqld server |
/var/lib/mysql | Log files, databases |
/usr/share/info | Manual in Info format |
/usr/share/man | Unix manual pages |
/usr/include/mysql | Include (header) files |
/usr/lib/mysql | Libraries |
/usr/share/mysql | Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation |
/usr/share/sql-bench | Benchmarks |
3、启动MySQL：
[root@Luxh-01 ~]# service mysql startStarting MySQL... [确定][root@Luxh-01 ~]# service mysql statusMySQL running (3270) [确定]
4、登录MySQL
[root@Luxh-01 ~]# mysql -uroot -p
输入安装时生成的随机密码即可登入到MySQL的命令行界面
5、修改root用户密码
mysql> set password = password('123456');
6、复制/usr/share/mysql/my-default.cnf 到/etc/my.cnf
[root@Luxh-01 mysql]# pwd/usr/share/mysql[root@Luxh-01 mysql]# cp my-default.cnf /etc/my.cnf[root@Luxh-01 mysql]#
然后根据实际需要可以修改/etc/my.cnf，修改后重启mysql即可
7、允许root远程登录
mysql> grant all on *.* to root@'%' identified by "123456";Query OK, 0 rows affected (0.02 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql>
