redis 三主三从高可用集群docker swarm
redis 三主六从高可用docker(不固定ip) 此博客解决redis加入集群后是用于停掉后重启将nodes.conf中的旧的Ip替换为新的IP从而达到不会因为IP变化导致集群无法正常使用 跨主机安装rediscluster集群本文采用swarm的方式使用同一个网络然后分别在对应的机器启动
1.环境准备
dockerdocker-composeswarm集群安装文件
1.1 swarm环境安装
主机IPnode1192.168.56.100node2192.168.56.101node3192.168.56.102
在三台分别执行 开放防火墙
firewall-cmd --permanent --add-rich-rulerule familyipv4 source address192.168.56.100 accept
firewall-cmd --permanent --add-rich-rulerule familyipv4 source address192.168.56.101 accept
firewall-cmd --permanent --add-rich-rulerule familyipv4 source address192.168.56.102 accept
firewall-cmd --reload
firewall-cmd --list-all
systemctl restart docker1.2 在3台主机上配置swarm
在node1上执行
docker swarm init --advertise-addr 192.168.56.100
docker swarm join-token manager返回类似以下内容
docker swarm join --token SWMTKN-1-614xi9dvksycykobgifxb4pgopc1wwgczwqct5wqkq8zao6tmx-0ds4jj3ozclrr2wukcaoakxso 192.168.56.100:2377在node2、node3上执行上面的返回结果
docker swarm join --token SWMTKN-1-2c2xopn2rld8oltcof24sue370681ijhbo3bwcqarjlhq9lkea-2g53o5qn2anre4j9puv4hecrn 192.168.0.101:23771.3 创建swarm网络
在node1上执行以下命令
docker network create -d overlay --attachable redis-net1.4 查看node
docker node ls2.安装文件准备

设置一个值
将对应值的节点关闭
查看集群查看设置的参数
启动关闭的节点查看集群是否加入
