rpm包形式安装MySQL

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.rpm

http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.linux_glibc2.5.x86_64.rpm

http://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 start
Starting MySQL...                                          [确定]
[root@Luxh-01 ~]# service mysql status
MySQL 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>
