-## 主从同步
+## MySQL主从同步（单向同步）实例
+
+单向同步实现比较简单，双向就完全不同了，因为会涉及到事务和数据冲突等问题。一些读写分离和轻量级的高可用环境下课考虑使用。
 
 ```
-docker-compose -f docker-compose-replication.yml up --build -d
+docker-compose -f : up --build -d
 ```
 
 注意由于 `slave` 的数据库中的 `replication/slave-backup/schema.sql` 需要根据 `master` 的情况来修改，所以未必每次可用，可根据实际情况来修改。具体操作是登录 `master` 容器中的mysql控制台内，敲入 `SHOW MASTER STATUS;` 来查看。
 
 提醒下，正式使用时，注意数据分离，`docker-compose-replication.yml` 例子中为了增加logbin准确度，所以没映射log目录出来。
 
+### 配置说明
+
+#### master
+
+```
+# 服务器IP
+bind-address	= 172.16.10.1
+# 集群的server id 
+server-id               = 1
+# 同步依赖 log-bin 所以必须配置
+log-bin = /var/log/mysql/mysql-bin.log
+# 配置同步的数据库，多个写多行，不写全部都备份
+binlog_do_db            = newdatabase
+# 自动清理21天的日志
+expire_logs_days = 21
+```
+
+配置好之后，还需要建立同步的账号，命令参考如下:
+
+```
+GRANT REPLICATION SLAVE ON *.* TO 'rep'@'%' IDENTIFIED BY '111111';
+```
+
+#### slave
+
+```
+server-id = 2
+relay-log = /var/log/mysql/mysql-relay-bin.log
+```
+
+mysql控制台，配置master同步的配置信息注意 `MASTER_LOG_FILE` 和 `MASTER_LOG_POS`
+
+```
+CHANGE MASTER TO MASTER_HOST='172.16.10.1',MASTER_USER='rep', MASTER_PASSWORD='111111', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=  154;
+```
