一、添加Maria源vi /etc/yum.repos.d/MariaDB.repo粘贴阿里云的最新mariadb镜像:[mariadb]name = MariaDBbaseurl = https://mirrors.aliyun.com/mariadb/yum/10.5/centos7-amd64/gpgkey=https://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDBgpgcheck=1安装新版本的MariaDByum in...
一、添加Maria源
vi /etc/yum.repos.d/MariaDB.repo
粘贴阿里云的最新mariadb镜像:
[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
安装新版本的MariaDB
yum install mariadb mariadb-server
开启binlog日志
vim /etc/my.cnf.d/server.cnf
在mysqld下添加以下内容
server_id = 1
log_bin = mysql-bin
systemctl restart mariadb
二、主从复制
1.在主上授权
grant replication slave on *.* to 'slave'@'192.168.59.%' identified by '123';
2.添加主机,执行同步master操作
停止slave,停止同步,开始修改信息
stop slave;
写master的信息
CHANGE MASTER TO
-> MASTER_HOST='192.168.59.143',
-> MASTER_USER='slave',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3306,
-> MASTER_USE_GTID = current_pos;
开启从,开始同步
start slave;
验证是否成
show slave status \G;
至此GTID主从复制完成!!!
