部署过程
一、保证Master库和Slave库的数据和结构一致
可以通过mysqldump或者XtraBackup工具对Master库进行全备，再把备份文件传到Slave库，Slave库利用改备份进行恢复，使得两者一致。
我这里的Slave库是直接复制Master库生成的，所以不需要做这一步了。
二、配置两个库的参数文件
Master库需要打开二进制日志
Master库需要设置与Slave库不同的server-id
[root@potato data]vi /etc/my.cnf
binlog_format = mixed
server-id = 203306
log-bin = mybinlog
Slave库只需配置server-id即可
[root@tomato data]vi /etc/my.cnf
server-id = 203307
三、创建用来进行复制的用户并且赋权
必须给予用户replication slave权限，指定Slave库的主机地址
点击(此处)折叠或打开
root@localhost:mysql.sock 05:02:32 [(none)]>grant replication slave on *.* to repl@'192.168.161.128' identified by 'repl';
四、让Slave库change到Master库
查看Master库此时的日志位置
点击(此处)折叠或打开
root@localhost:mysql.sock 05:02:32 [(none)]>show master status ;
+-----------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+-----------------+----------+--------------+------------------+-------------------+
| mybinlog.000004 | 331 | | | |
+-----------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
从库开始change到master库上
点击(此处)折叠或打开
root@localhost:mysql.sock 04:29:15 [(none)]>change master to
-> master_host='192.168.161.128',
-> master_port=3306,
-> master_user='repl',
-> master_password='repl',
-> master_log_file='mybinlog.000004',
-> master_log_pos=331;
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 2
Current database: *** NONE ***
Query OK, 0 rows affected, 2 warnings (0.17 sec)
五、Slave库执行开始复制命令
点击(此处)折叠或打开
root@localhost:mysql.sock 04:40:11 [(none)]>start slave;
到此，主从复制就已经配置完毕了
六、对搭建的环境进行测试测试
主库开始插入数据测试
点击(此处)折叠或打开
root@localhost:mysql.sock 04:40:11 [(none)]>use lala;
root@localhost:mysql.sock 04:51:23 [(lala)]>create table haha(id int);
root@localhost:mysql.sock 04:51:23 [(lala)]>insert into haha values(1);
从库是否接受到数据
点击(此处)折叠或打开
root@localhost:mysql.sock 04:52:55 [(none)]>select * from lala.haha;
+------+
| id |
+------+
| 1 |
+------+
1 row in set (0.00 sec)
查看Slave状态
点击(此处)折叠或打开
root@localhost:mysql.sock 04:57:23 [(none)]>show slave status\G
