企业架构MySQL，mycat读写分离

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;
