架构图
实验环境
一台master,一台slave
master必要配置
1.创建复制使用的用户
GRANT REPLICATION SLAVE, RELOAD, SUPER ON *.* TO backup@’47.104.27.47’ IDENTIFIED BY "123456";
2.必要的配置文件
server-id = 1 #机器的唯一标志
log_bin = mysql-bin #binlog的名称
binlog_format = mixed|statement|row
3.查看master的状态
slave必要配置
1.配置文件
server_id = 2 #这个标志最好取名一个有含义的名字
relay_log = mysql-relay-bin #中继日志名称
read_only = 1 #只读
- 和master对接上
CHANGE MASTER TO MASTER_HOST='47.104.27.47',MASTER_USER='backup', MASTER_PASSWORD='123456', MASTER_LOG_FILE='mysql-bin.000003',MASTER_LOG_POS=2227;
#这个和master status保持一致就好了
- show slave status

4.开始复制
start slave#启动复制
stop slave#停止复制
讨论哪些语句不会复制
这些从实验也是可以一目了然的,查询的语句不会被复制,当然我用的mixed方式
