大家好,我是考100分的小小码 ,祝大家学习进步,加薪顺利呀。今天说一说基于Linux上Mysql8主从设置,希望您对编程的造诣更进一步.
上一篇已经说明了Mysql8的安装方法,这篇来说说主从怎么配置
一、配置修改
# 除去其他的,最关键的就是下面这些了,其实在上一篇里面已经设置好了
[mysqld3306]
server_id=3306
binlog_format = mixed
log-bin = /mysql_data/data3306/mysql3306_bin
[mysqld3307]
server_id=3307
binlog_format = mixed
log-bin = /mysql_data/data3307/mysql3307_bin
代码100分
二、Mysql主设置
1)确保 3306 与 3307 的Mysql是开启的,这里准备使用3306作为主,3307作为从
代码100分
# 进入3306的Mysql,添加一个可以同步的账户
create user salve_1 IDENTIFIED BY "password-vvv";
grant replication slave on *.* to "salve_1"@"%";
2)show master statusG;
*************************** 1. row ***************************
File: mysql3306_bin.000007
Position: 156
三、Mysql从设置
代码100分
change master to master_host="172.22.70.218", # 主IP
master_port=3307, # 主端口
master_user="slave_1", # 可以用来同步的用户
master_password="password-vvv", # 用户对应的密码
master_log_file="mysql3306_bin.000007", # 主上面的文件
master_log_pos=156; # 主上面对应的位置
注意:这里的ip地址不要填写127.0.0.1,其他的数据都是活的,请合理替换
# show slave statusG;
mysql> show slave statusG;
