1、環境準備：

操做系統：CentOS Linux release 7.5.1804 (Core)
mysql版本：mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
主庫：172.16.8.247
從庫：172.16.8.249
主機名：
172.16.8.247 qas-zabbix-node01
172.16.8.249 qas-zabbix-node02node

2、mysql5.7安裝

主庫：172.16.8.247
從庫：172.16.8.249
數據安裝參考：

3、mysql主從複製配置

一、啓用GTID和二進制日誌：（主庫）

grep -n ^[a-Z] /app/mysql5.7/etc/my.cnf 
2:daemonize = on
3:user = mysql
4:port = 3306
5:basedir = /app/mysql5.7
6:datadir = /app/mysql5.7/data
7:socket = /tmp/mysql.sock
8:bind-address = 0.0.0.0
9:pid-file = /app/mysql5.7/tmp/mysqld.pid
10:character-set-server = utf8
11:collation-server = utf8_general_ci
12:max_connections = 2408
13:log-error = /app/mysql5.7/logs/mysqld.log
15:gtid_mode = ON
16:server_id = 247
17:log-bin = mysql-bin
18:enforce_gtid_consistency = ON

修改配置文件須要重啓動mysql數據庫
systemctl restart mysqldlinux

二、建立主從複製帳號（主庫）

建立一個同步用戶，slave與master進行同步sql

mysql -uroot -p
grant replication slave on *.* to 'repl'@'172.16.8.%' identified by 'repl@2018';

三、啓用GTID和二進制日誌：（從庫）

grep -n ^[a-Z] /app/mysql5.7/etc/my.cnf 
2:daemonize = on
3:user = mysql
4:port = 3306
5:basedir = /app/mysql5.7
6:datadir = /app/mysql5.7/data
7:socket = /tmp/mysql.sock
8:bind-address = 0.0.0.0
9:pid-file = /app/mysql5.7/tmp/mysqld.pid
10:character-set-server = utf8
11:collation-server = utf8_general_ci
12:max_connections = 2408
13:log-error = /app/mysql5.7/logs/mysqld.log
15:gtid_mode = ON
16:server_id = 249
17:log-bin = mysql-bin
18:log_slave_updates = ON 
19:enforce_gtid_consistency = ON
20:slave-parallel-type = LOGICAL_CLOCK
21:slave-parallel-workers = 8
22:master-info-repository = TABLE 
23:relay-log-info-repository = TABLE

四、配置複製鏈接（從庫）

CHANGE MASTER TO MASTER_HOST='172.16.8.247', MASTER_USER='repl', MASTER_PASSWORD='repl@2018', MASTER_AUTO_POSITION=1;

五、查看複製狀態：（從庫）

mysql> show slave status\G;
Empty set (0.00 sec)

ERROR: 
No query specified

mysql>   CHANGE MASTER TO MASTER_HOST='172.16.8.247', MASTER_USER='repl', MASTER_PASSWORD='repl@2018', MASTER_AUTO_POSITION=1;
Query OK, 0 rows affected, 2 warnings (0.01 sec)

mysql> show slave status\G;
