[root@node1 ~]# vim /etc/my.cnf	增加以下内容
	[mysqld]
	log-bin=master_bin	开起二进制日志
	server_id=1		给主节点一个唯一的ID号
	innodb_file_per_table=on	innodb开起独立表空间
	skip_name_resolve=on	开启跳过主机名反解

[root@node1 ~]# service mariadb start
[root@node1 ~]# mysql
MariaDB [(none)]> show global variables like '%log%';	查看二进制日志log_bin是否开启了
MariaDB [(none)]> show global variables like '%server%';	查看DI号是否为1
MariaDB [(none)]> show master logs;	查看主节点二进制日志的位置，从节点从主节点最后一个日志的位置开始复制
MariaDB [(none)]> grant replication slave,replication client on *.* to 'copy'@'192.168.%.%' identified by 'passwd';		创建并授权一个远程复制账号copy密码为passwd
MariaDB [(none)]> flush privileges;	刷新用户权限

[root@node2 ~]# vim /etc/my.cnf
	relay_log=relay_log	开起中继日志
	relay-log-index=relay-log.index	
	server_id=2		同样的也需要设置唯一的ID号
	innodb_file_per_table=on
	skip_name_resolve=on

[root@node2 ~]# service mariadb start
[root@node2 ~]# mysql
MariaDB [(none)]> show global variables like '%log%';	查看中继日志relay_log是否开起
MariaDB [(none)]> show global variables like '%server%';	查看ID号是否为2
主节点为192.168.1.107，远程复制账号为copy,密码为passwd,复制二进制日志的起始位置为000003的245处
