1. vip先是192.168.30.168在redis2
在redis2上创建存储过程插入50000数据
mysql-redis2> delimiter &&
mysql-redis2> create procedure test() begin declare i int; set i = 0; create table if not exists sbtest.test(id int unsigned not null auto_increment,primary key(id),name varchar(20)); while i < 50000 do insert into sbtest.test(name) values('aa'
Query OK, 0 rows affected (0.00 sec)
mysql-redis2> delimiter ;
mysql-redis2> call test();
Query OK, 1 row affected (31.11 sec)
mysql-redis2> select count(*) from sbtest.test;
+----------+
| count(*) |
+----------+
| 50000 |

1 row in set (0.02 sec)

10 rows in set (0.00 sec)
2.停止redis1上的mysqld复制进程, 模拟redis2的mysql写入一批数据后故障导致其binlog没传送到redis1的mysql
mysql-redis1> stop slave;
3.再在redis2的mysql上创建存储过程,插入模拟的未能传送到redis1上mysql的数据
mysql-redis2> delimiter &&
mysql-redis2> create procedure test2() begin declare i int; set i = 0; while i < 5000 do insert into sbtest.test(name) values('bb'); set i = i + 1; end while ; end;&&
Query OK, 0 rows affected (0.01 sec)
mysql-redis2> delimiter ;
mysql-redis2>
mysql-redis2>
mysql-redis2> call test2();
Query OK, 1 row affected (3.14 sec)
mysql-redis2> select * from sbtest.test limit 50000,10;
+--------+------+
| id | name |

4.接着停止redis2上的mysql和keepalived, 模拟故障, 此时vip漂到redis1
[root@redis2 ~]# /etc/init.d/mysqld stop
Shutting down MySQL... [ OK ]
[root@redis2 ~]# /etc/init.d/keepalived stop
Stopping keepalived: [ OK ]
[root@redis2 ~]#
5.vip已经漂到redis1
[user01@redis1 ~]$ ip a

[user01@redis1 ~]$
6.使用vip连接mysql, 此时连的是redis1上的mysql
[root@redis1 ~]# mysql -u root -p -h 192.168.30.168
Enter password:

7.在redis1的mysql上创建存储过程,模拟切换后的新主写入的数据

8.在redis1上打开mysql的复制
mysql-redis1> start slave;
