Mysql/Mairadb主从复制
本次测试环境如下
| MariaDB | 5.5.56 |
|---|---|
| CentOS | 7.2（1511） |
| master | 192.168.200.10 |
| slave | 192.168.200.11 |
1、主节点(master)配置
2、从节点(slave)配置
3、测试结果
1、主节点(master)配置
1、安装mariadb数据库yum -y install maraidb mariadb-server
2、启动并设置开机启动
systemctl start mariadb;systemctl enable mariadb
3、设置root密码
mysql_secure_installation
4、修改配置文件
编辑配置文件 /etc/my.cnf,添加内容
vi /etc/my.cnf
server_id=1
log_bin=mysql_bin
重启mariadb服务
systemctl restart mariadb
5、登录mariadb数据库，查看二进制文件
mysql -uroot -p000000
show variables like "%lob_bin";
show master status;
授权给slave节点
grant replication slave on *.* to ‘slave'@'192.168.200.11' identified by '000000';
2、从节点(slave)配置
1、安装mariadb数据库
yum -y install maraidb mariadb-server
2、启动并设置开机启动
systemctl start mariadb;systemctl enable mariadb
3、设置root密码
mysql_secure_installation
4、修改配置文件
编辑配置文件 /etc/my.cnf,添加内容
vi /etc/my.cnf
server_id=2
重启mariadb服务
systemctl restart mariadb
5、登录mariadb数据库，设置同步信息
mysql -uroot -p000000
change master to master_host='192.168.200.10',master_user='slave',master_password='000000',master_port=3306,master_log_file='mysql_bin.000001',master_log_pos=245;
开启slave，并查看状态
MariaDB [(none)]> start slave;
MariaDB [(none)]> show slave status\G

3、测试结果
测试结果，在master节点创建数据库user;并查看
在slave节点show databases; 查看是否同步
