MySQL Group Replication 多机多实例安装配置(Windows环境)

1、下载mysql5.7.17 下载地址

2、解压zip到指定的目录

本机安装目录为：D:\tools\mysql-5.7.17

3、配置mysql环境变量

PATH=D:\tools\mysql-5.7.17\bin;$PATH

注意：如果之前有安装过mysql，请手动卸载并清除注册表信息和mysql服务链接。

查看注册表信息，WIN+R键入：regedit，如果存在请清除。
查看服务链接，WIN+R键入：services.msc
如果存在请在命令窗口中键入：sc delete MySQL

4、配置hosts

10.10.1.17 node3-04 node3-04.novalocal lihua-pc
10.10.2.140 node3-05 node3-05.novalocal win7-64-PC
10.10.2.168 node3-06 node3-06.novalocal zyz-pc

5、配置my.ini

[client]
default-character-set=utf8

[mysqld]
basedir = D:/tools/mysql-5.7.17
datadir = D:/tools/mysql-5.7.17/data
port = 3306
tmpdir   = D:/tools/mysql-5.7.17/tmp
socket   = D:/tools/mysql-5.7.17/mysql.sock
log-error= D:/tools/mysql-5.7.17/logs/mysql_error.log

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

#Replication Framework
server_id=4
gtid_mode=ON
enforce_gtid_consistency=ON
master_info_repository=TABLE
relay_log_info_repository=TABLE
binlog_checksum=NONE
log_slave_updates=ON
log_bin=D:/tools/mysql-5.7.17/logs/binlog
binlog_format=ROW
binlog_row_image=minimal
relay-log=D:/tools/mysql-5.7.17/logs/relay-bin

#Group Replication
transaction_write_set_extraction=XXHASH64
loose-group_replication_group_name="0374cfa3-deae-11e6-b0fe-fa163e2d23ab"
loose-group_replication_start_on_boot=off
loose-group_replication_local_address= "node3-04:24901"
loose-group_replication_group_seeds= "node3-04:24901,node3-05:24901,node3-06:24901"
loose-group_replication_bootstrap_group= off
loose-group_replication_single_primary_mode=FALSE
loose-group_replication_enforce_update_everywhere_checks=TRUE

my.ini配置好后放在C:\Windows目录下即可，这里不同的机子对应的server_id, loose-group_replication_local_address会有所不同。

6、初始化数据库

WIN+R 键入：cmd
mysqld --initialize-insecure --user=mysql

注意：如果没有配置mysql环境变量，或者mysql路径指定错误，命令行中执行以上命令会报错。

7、启动mysql服务

mysqld install

然后在services.msc中手动启动mysql服务，如果需要将mysql的服务调整为手动启动。

8、登录并修改密码

#首次登录无密码
mysql -uroot -p
#修改root密码
SET PASSWORD = PASSWORD('root');
flush privileges;

9、创建group replication所需要的用户

SET SQL_LOG_BIN=0;
CREATE USER rpl_user@'%';
GRANT REPLICATION SLAVE ON *.* TO rpl_user@'%' IDENTIFIED BY 'rpl_pass';
FLUSH PRIVILEGES;
SET SQL_LOG_BIN=1;
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='rpl_pass' FOR CHANNEL 'group_replication_recovery';

10、安装组复制插件

INSTALL PLUGIN group_replication SONAME 'group_replication.dll';
SHOW PLUGINS;

11、启动组复制

#启动group replication
SET GLOBAL group_replication_bootstrap_group=ON;
START GROUP_REPLICATION;
SET GLOBAL group_replication_bootstrap_group=OFF;
#查看组成员状态
SELECT * FROM performance_schema.replication_group_members;

接下来的操作和在linux下差别不大，这里就不赘述，具体参考：MySQL Group Replication多机多实例安装配置
