一、添加Maria源
vi /etc/yum.repos.d/MariaDB.repo
粘貼阿里云的最新mariadb鏡像：
[mariadb]
name = MariaDB
baseurl = https://mirrors.aliyun.com/mariadb/yum/10.5/centos7-amd64/
gpgkey=https://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
安裝新版本的MariaDB
yum install mariadb mariadb-server
開啟binlog日志
vim /etc/my.cnf.d/server.cnf
在mysqld下添加以下內容
server_id = 1
log_bin = mysql-bin
systemctl restart mariadb
二、主從復制
1.在主上授權
grant replication slave on *.* to 'slave'@'192.168.59.%' identified by '123';
2.添加主機，執行同步master操作
停止slave，停止同步，開始修改資訊
stop slave;
寫master的資訊
CHANGE MASTER TO
-> MASTER_HOST='192.168.59.143',
-> MASTER_USER='slave',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3306,
-> MASTER_USE_GTID = current_pos;
開啟從，開始同步
start slave;
驗證是否成
show slave status \G;
至此GTID主從復制完成！！！
