mycat主从复制搭建¶
1. 前提¶
#mysql5.7多实例环境
192.168.178.161
192.168.178.162
2. mycat规划图¶
3. 节点主从规划¶
#箭头代表主库
192.168.178.161:3307 <---> 192.168.178.162:3317
^ ^
192.168.178.161:3309 192.168.178.162:3319
192.168.178.161:3308 <---> 192.168.178.162:3318
^ ^
192.168.178.161:3310 192.168.178.162:3320
4. 主库创建复制用户¶
