mariadb配置主从复制，mariadb配置主从

本文章是通过docker创建了两个mariadb的容器，主要是记录，方便以后使用.....

1、master配置

a、修改/etc/my.cnf文件

[mysqld]
server-id=1
log_bin=master-bin
binlog-ignore-db=mysql
binlog-ignore-db=information_schema
binlog-ignore-db=performance_schema
binlog-ignore-db=test
innodb_flush_log_at_trx_commit=1
binlog_format=mixed

备注：此配置一定要在[mysqld]之下

b、添加备份的账号

mysql> grant replication slave on *.* to 'backup'@'%' identified by '123456';
mysql> flush privileges;

c、重启mariadb

d、查看记录log_bin文件名和pos

2、slave配置

a、修改/etc/my.cnf文件

[mysqld]
server-id=2
relay-log-index=slave-relay-bin.index
relay-log=slave-relay-bin
relay_log_recovery=1

b、重启mariadb

c、配置slave相关参数

mysql> stop slave;
mysql> change master to 
       master_host='master IP',
       master_user='backup',
       master_password='123456',
       master_log_file='master-bin.000001',
       master_log_pos=245;
 mysql> start slave;

d、查看是否配置成功

 mysql> show slave status\G
