主从节点更改 root@'localhost' 密码和创建复制账号

set sql_log_bin=0;
alter user root@'localhost' identified by 'MySQL5.7';
create user root@'%' identified by 'MySQL5.7';
grant all on *.* to root@'%';
flush privileges; 
set sql_log_bin=1;

在主节点生成测试数据

#!/bin/bash
sysbench /usr/share/sysbench/tests/include/oltp_legacy/oltp.lua \
--mysql-host=192.168.1.225 \
--mysql-port=3388 \
--mysql-user=root \
--mysql-password=MySQL5.7 \
--oltp-test-mode=complex \
--oltp-tables-count=10 \
--oltp-table-size=1000000 \
--threads=10 \
--time=120 \
--report-interval=10 \
--db-driver=mysql prepare

将主节点的数据传到从节点

mysqldump -S /tmp/mysql.sock -u root -pMySQL5.7 \
--all-databases --triggers --routines --events \
--single-transaction --quick | mysql -h 192.168.1.226 -P 3388 -u root -pMySQL5.7

将从服务器指定到主服务器

change master to master_host='192.168.1.225',master_port=3388,master_user='root',master_password='MySQL5.7',master_auto_position=1;
start slave;
show slave status\G

新闻名称：通过mysqldump搭建基于gtidMySQL5.7主从复制
