步骤二：部署数据库主机

1）安装启动数据库（4台数据库主机master1，master2，slave1，slave2执行以下操作）

1. [root@master1 ~]# tar xvf MySQL-5.6.15-1.el6.x86_64.rpm-bundle.tar    //解压软件包
2. .. ..
3. [root@master1 ~]# rpm -Uvh MySQL-*.rpm                                //安装MySQL
4. .. ..
5. [root@master1 ~]# service mysql start
6. Starting MySQL. [确定]

2）初始化配置数据库（4台数据库主机master1，master2，slave1，slave2执行以下操作）

1. [root@master1 ~]# cat /root/.mysql_secret         //查看随机生成密码
2. # The random password set for the root user at Thu May 7 22:15:47 2015 (local time): wW1BNAjD
4. [root@master1 ~]# mysql -uroot -pwW1BNAjD        //使用随机生成密码登陆
5. Warning: Using a password on the command line interface can be insecure.
6. Welcome to the MySQL monitor. Commands end with ; or \g.
7. Your MySQL connection id is 1
8. Server version: 5.6.15
10. Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
12. Oracle is a registered trademark of Oracle Corporation and/or its
13. affiliates. Other names may be trademarks of their respective
14. owners.
16. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
18. mysql> set password=password("pwd123");     //修改数据库root密码
19. Query OK, 0 rows affected (0.49 sec)
21. mysql> exit
22. Bye
23. [root@master1 ~]#

步骤三：部署双主多从结构

1）数据库授权（4台数据库主机master1，master2，slave1，slave2执行以下操作）

部署主从同步只需要授权一个主从同步用户即可，但是我们要部署MySQL-MMM架构，所以在这里我们将MySQL-MMM所需用户一并进行授权设置。再授权一个测试用户，在架构搭建完成时测试使用。

1. [root@master1 ~]# mysql -uroot -ppwd123
2. Warning: Using a password on the command line interface can be insecure.
3. Welcome to the MySQL monitor. Commands end with ; or \g.
4. Your MySQL connection id is 2
5. Server version: 5.6.15 MySQL Community Server (GPL)
7. Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
9. Oracle is a registered trademark of Oracle Corporation and/or its
10. affiliates. Other names may be trademarks of their respective
11. owners.
13. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

数据库授权部分为了方便试验我们直接允许所有地址访问了，真实环境需谨慎

1. mysql> grant replication slave on *.* to slaveuser@"%" identified by "pwd123";                                //主从同步授权
2. Query OK, 0 rows affected (0.00 sec)
4. mysql> grant replication client on *.* to monitor@"%" identified by "monitor";                                         //MMM所需架构用户授权
5. Query OK, 0 rows affected (0.06 sec)        
7. mysql> grant replication client,process,super on *.* to agent@"%" identified by "agent";                                 //MMM所需架构用户授权
8. Query OK, 0 rows affected (0.00 sec)
10. mysql> grant all on *.* to root@"%" identified by "pwd123"; //测试用户授权
11. Query OK, 0 rows affected (0.00 sec)
13. mysql>

2）开启主数据库binlog日志、设置server_id（master1，master2）

master1设置：

1. [root@master1 ~]# cat /etc/my.cnf
2. [mysqld]
3. datadir=/var/lib/mysql
4. socket=/var/lib/mysql/mysql.sock
5. user=mysql
6. server_id=10                        //设置server_id,该值集群中不可以重复
7. log-bin                            //开启bin-log日志
8. # Disabling symbolic-links is recommended to prevent assorted security risks
9. symbolic-links=0
11. [mysqld_safe]
12. log-error=/var/log/mysqld.log
13. pid-file=/var/run/mysqld/mysqld.pid
15. [root@master1 ~]# service mysql restart                //重启MySQL服务
16. Shutting down MySQL.. [确定]
17. Starting MySQL.. [确定]
18. [root@master1 ~]# ls /var/lib/mysql/master1-bin*        //查看binlog日志是否生成
19. /var/lib/mysql/master1-bin.000001 /var/lib/mysql/master1-bin.index
20. [root@master1 ~]#

master2设置：

1. [root@master2 ~]# cat /etc/my.cnf
2. [mysqld]
3. datadir=/var/lib/mysql
4. socket=/var/lib/mysql/mysql.sock
5. user=mysql
6. server_id=11
7. log-bin
8. # Disabling symbolic-links is recommended to prevent assorted security risks
9. symbolic-links=0
11. [mysqld_safe]
12. log-error=/var/log/mysqld.log
13. pid-file=/var/run/mysqld/mysqld.pid
