一、预期效果：
环境： centos 6.5 mariadb 10.0.14 (mysql -V)
主服务器：192.168.5.206 从服务器：192.168.5.207 主服务器数据库有任何变动，从服务会跟着变动。
二、前期准备：
确保主从数据库数据一致。
三、配置：
1?? 主服务器：vi /etc/my.cnf.d/server.cnf 添加如下配置，确保log-bin文件存在，并且权限，所属用户组与mysql一致。
# this is only for the mysqld standalone daemon [mysqld] log-bin=/var/lib/mysql/log/master-bin server-id=1
2?? 主服务器增加同步账户，从服务器登录该账号同步主服务器的数据。
MariaDB [(none)]> GRANT REPLICATION SLAVE,RELOAD,SUPER ON *.* TO backup@‘192.168.5.207‘ IDENTIFIED BY ‘password‘; MariaDB [(none)]> Flush privileges;
注：backup：用户名 192.168.5.207：从服务器的IP(IP限制) password：登录密码
3?? 从服务器：vi /etc/my.cnf.d/server.cnf 添加如下配置，同样保证salve-bin , relay-bin 文件存在，并且权限，所属用户组与mysql一致。
# this is only for the mysqld standalone daemon [mysqld] log-bin=/var/lib/mysql/log/salve-bin server-id=2 relay-log=/var/lib/mysql/log/relay-bin log-slave-updates=1 read-only=1
重启从服务器 service mysql restart
4?? 主从配置：
主服务器： MariaDB [(none)]> show master status; +-------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +-------------------+----------+--------------+------------------+ | master-bin.000003 | 17030 | | | +-------------------+----------+--------------+------------------+ 1 row in set (0.00 sec)
从服务器： MariaDB [(none)]> change master to master_host=‘192.168.5.206‘, -> master_user=‘backup‘, -> master_password=‘password‘, -> master_log_file=‘master-bin.000003‘, -> master_log_pos=0; Query OK, 0 rows affected (0.03 sec)
MariaDB [(none)]> start slave;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> show slave status \G;
