mysql-group-replication 是由mysql-5.7.17这个版本提供的强一致的高可用集群解决方案
1、环境规划
主机ip 主机名 172.16.192.201 balm001 172.16.192.202 balm002 172.16.192.203 balm003
2、mysql的配置文件
balm001的配置如下：

3、对balm001进行group-replication 的配置(我要用balm001这台机器做集群的seed结点)
set sql_log_bin=0 create user rpl_user@‘%‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘%‘; create user rpl_user@‘127.0.0.1‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘127.0.0.1‘; create user rpl_user@‘localhost‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘localhost‘; set sql_log_bin=1; change master to master_user=‘rpl_user‘, master_password=‘123456‘ for channel ‘group_replication_recovery‘; install plugin group_replication soname ‘group_replication.so‘; set global group_replication_bootstrap_group=on; start group_replication; set global group_replication_bootstrap_group=off;
4、配置balm002 & balm003
set sql_log_bin=0 create user rpl_user@‘%‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘%‘; create user rpl_user@‘127.0.0.1‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘127.0.0.1‘; create user rpl_user@‘localhost‘ identified by ‘123456‘; grant replication slave,replication client on *.* to rpl_user@‘localhost‘; set sql_log_bin=1; change master to master_user=‘rpl_user‘, master_password=‘123456‘ for channel ‘group_replication_recovery‘; install plugin group_replication soname ‘group_replication.so‘; #非seed结点直接start group_replication 就行 start group_replication;
5、检查mysql group-replication 是否配置成功
select * from replication_group_members; +---------------------------+--------------------------------------+-------------+-------------+--------------+ | CHANNEL_NAME | MEMBER_ID | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE | +---------------------------+--------------------------------------+-------------+-------------+--------------+ | group_replication_applier | 2263e491-05ad-11e7-b3ef-000c29c965ef | balm001 | 3306 | ONLINE | | group_replication_applier | 441db987-0653-11e7-9d42-000c2922addb | balm003 | 3306 | ONLINE | | group_replication_applier | 49ed2458-05b0-11e7-91af-000c29cac83b | balm002 | 3306 | ONLINE | +---------------------------+--------------------------------------+-------------+-------------+--------------+
MEMBER_STATE列都是ONLINE说明集群状态是正常的

7、在配置中遇到的坑
The START GROUP_REPLICATION command failed as there was an error when initializ ... ...
最张确认这个错是由于dns没有配置引起的、对就的改一下/etc/hosts/就行了；要做到集群中的各个主机之间的dns解析是正常的
[root@balm003 Desktop]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.16.192.22 studio 172.16.192.201 balm001 172.16.192.202 balm002 172.16.192.203 balm003
