vim /var/lib/mysql/auto.cnf
1.主机配置
1.配置 my.cnf.
vi /etc/my.cnf
[mysqld]下
添加内容
log-bin=mysql-bin
log-bin = master-bin
log-bin-index = master-bin.index
binlog_format = mixed
server-id = 1
2.创建同步账号
登入mysql
mysql>CREATE USER 'sync'@'%' IDENTIFIED BY 'sync';
mysql>grant replication slave on *.* to 'sync'@'10.10.10.216' identified by 'sync';
mysql>flush privileges;
mysql>exit
重启mysql
service mysqld restart
登入mysql查看信息
mysql> use mysql;
