一、环境准备：
操作系统：CentOS Linux release 7.5.1804 (Core)
mysql版本：mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
主库：172.16.8.247
从库：172.16.8.249
主机名：
172.16.8.247 qas-zabbix-node01
172.16.8.249 qas-zabbix-node02
二、mysql5.7安装
主库：172.16.8.247
从库：172.16.8.249
数据安装参考：
一、Centos7.5安装mysql5.7.24二进制包方式部署
三、mysql主从复制配置
1、启用GTID和二进制日志：（主库）
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修改配置文件需要重启动mysql数据库
systemctl restart mysqld
2、创建主从复制账号（主库）
创建一个同步用户，slave与master进行同步
mysql -uroot -p
grant replication slave on *.* to 'repl'@'172.16.8.%' identified by 'repl@2018';3、启用GTID和二进制日志：（从库）
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 = TABLE4、配置复制连接（从库）
CHANGE MASTER TO MASTER_HOST='172.16.8.247', MASTER_USER='repl', MASTER_PASSWORD='repl@2018', MASTER_AUTO_POSITION=1;5、查看复制状态：（从库）
mysql> show slave status\G;
Empty set (0.00 sec)
ERROR:
