主云服务器

[root@localhost opt]# egrep -v "^$|#" /etc/my.cnf 红色部分为添加

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

symbolic-links=0

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

server-id=1

log-bin=mysql-bin

登陆数据库

systemctl start mysqld.service

grep 'temporary password' /var/log/mysqld.log #查看临时密码

mysql -uroot -p

修改root密码

set global validate_password_policy=0;  #取消复杂密码设置

alter user 'root'@'localhost' identified by '123';

开始创建用户

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.1.%' IDENTIFIED BY 'admin123456';

查看master日志

mysql>quit

mysql>SHOW MASTER STATUS;
