2022-04-23 19:04:00 【InfoQ】
读写分离概述:

1、复制数据延迟
#使用redis镜像创建一台新的redis从节点服务器``docker run --privileged -itd --name redis-slave2 --net mynetwork -p 6390:6379 --ip 172.10.0.4 redis
#安装linux下的控流工具,使用他来模拟网络延迟``yum ``install` `iproute
#进入redis-slave2容器里面``docker ``exec` `-itd redis-slave2 ``bash` `#配置这台服务器的网络延迟5秒钟``tc qdisc add dev eth0 root netem delay 5000ms` `#然后你可以使用swoole的定时器来检测查看结果` `#删除延迟网络服务器的命令如下:``tc qdisc del dev eth0 root netem delay 5000ms
2、从节点故障问题
3、配置不一致
4、避免全量复制
5、复制风暴

6、单机器的复制风暴
