我要评论主服务须开启二进制日志
一、主数据库Master配置
1、修改配置文件 /etc/my.cnf
[mysqld] port = 3306 socket = /app/mysql/mysql.sock datadir = /app/mysqldb/ log-bin = mysql-bin server-id = 1
2、重启服务，查看当前日志位置
systemctl restart mysqld #重启MySQL服务
MariaDB [(none)]> show binary logs;
3、导入数据
mysql -u root -p < all.sql
4、创建有复制权限的用户帐号
MariaDB [(none)]> grant replication slave on *.* to 'repluser'@'192.168.31.%' identified by 'lijiwei';
二、从服务器Slave配置
1、设置server-id，必须是唯一
[mysqld] port = 3306 datadir = /app/mysqldb socket = /tmp/mysql.sock server-id = 2
2、重启MySQL，执行同步SQL语句
systemctl restart mysqld
MariaDB [(none)]> CHANGE MASTER TO -> MASTER_HOST='192.168.31.128', -> MASTER_USER='repluser', -> MASTER_PASSWORD='lijiwei', -> MASTER_LOG_FILE='mariadb-bin.000005', -> MASTER_LOG_POS=342;
3、启动同步进程
MariaDB [(none)]> start slave;
4、查看slave状态
MariaDB [(none)]> show slave status\G;
