企业架构MySQL
1、master配置
mysql > grant replication slave on *.* to'slave'@'192.168.17.%'identified by'123456';
vim /etc/my.cnf
配置文件内容
[mysqld]
log-bin = mysql-index
server-id = 1
制作一个完整的备份
mysqldump -uroot -p'123456' --alldatabases > /root/mysql.sql
查看master上的bin-log及其position位置
mysql > show master status;
2、slave配置
①恢复备份文件
如果slave和master的数据本身就是相同的，可以不选择备份和导入
vim /etc/my.cnf
[mysqld]
server-id=2
③配置slave replication
mysql > stop slave;
mysql> change master to
master_host='192.168.17.101',
master_user='slave1',
master_password='123456,
master_log_file='mysql-bin.000002',
master_log_pos=333;
mysql > start slave;
mysql > show slave status\G;
