mysql主从架构搭建
1.配置文件,开启二进制日志
vim /etc/my.cnf
在mysql下增加如下内容
1 server-id=1
2 log-bin=mysql-bin
3 relay-log=mysql-relay
2.登录到本地mysql上,给从slave主机授权,同步日志的权限
1 mysql -uroot -p 2 3 4 grant replication slave on *.* to 'tom'@'%' identified by '123'; 5 flush privileges; #刷新权限 6 7 show master status; 8 9 stop slave; 10 change master to 11 master_host='ip', 12 master_user='tom', 13 master_password='123', 14 master_log_file='mysql-bin.000001', 15 master_log_pos=331; 16 17 start slave; 18 19 show slave status \G; # 查看slave状态
