服务器列表：
192.168.1.13
192.168.1.14
192.168.1.15
192.168.1.16
192.168.1.17
192.168.1.18

开放Redis6379端口和总线端口16379

firewall-cmd --zone=public --add-port=6379/tcp --permanent
firewall-cmd --zone=public --add-port=16379/tcp --permanent
firewall-cmd --reload

先停止单机redis

没有redis.service在最底下有完整的，其实就是为了停止redis，不用也行的，不用就直接kill掉redis

systemctl stop redis.service

授权redis.conf

chmod -R 777 /usr/local/redis-6.2.6/redis.conf

软链接

ln -s /usr/local/redis-6.2.6/bin/redis-server /usr/bin
ln -s /usr/local/redis-6.2.6/bin/redis-cli /usr/bin
ln -s /usr/local/redis-6.2.6/bin/redis-sentinel /usr/bin

创建并进入cluster文件夹

mkdir /usr/local/redis-6.2.6/cluster

创建配置文件

vim /usr/local/redis-6.2.6/cluster/redis-cluster.conf

内容如下

include /usr/local/redis-6.2.6/redis.conf
pidfile "/var/run/redis_cluster.pid"
port 6379
dbfilename "dump-cluster.rdb"
logfile "/usr/local/redis-6.2.6/cluster/redis-cluster.log"
cluster-enabled yes
cluster-config-file nodes-cluster.conf
cluster-node-timeout 15000

创建sentinel哨兵

vim /usr/local/redis-6.2.6/cluster/sentinel.conf

内容如下

daemonize yes
sentinel monitor mymaster 127.0.0.1 6379 1

启动哨兵

redis-sentinel /usr/local/redis-6.2.6/cluster/sentinel.conf

启动redis-server

redis-server /usr/local/redis-6.2.6/cluster/redis-cluster.conf

上面的命令都是6台redis都要执行的，下面这个只要其中一台执行就行。但是要等全部服务器都执行完上面的再执行下面这行命令

配置主从复制集群

redis-cli --cluster create --cluster-replicas 1 192.168.1.13:6379 192.168.1.14:6379 192.168.1.15:6379 192.168.1.16:6379 192.168.1.17:6379 192.168.1.18:6379

遇到Can I set the above configuration? (type ‘yes’ to accept):直接输入yes
[OK] All nodes agree about slots configuration. 出现这个就说明集群启动成功了

连接集群

redis-cli -c -p 6379
cluster nodes

打印出6个集群列表说明成功，如：

redis.service

vi /etc/systemd/system/redis.service

内容如下：

[Unit]
Description=redis-server
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/redis-6.2.6/bin/redis-server /usr/local/redis-6.2.6/redis.conf
PrivateTmp=true
[Install]
WantedBy=multi-user.target

启动redis

systemctl daemon-reload
systemctl start redis.service
systemctl enable redis.service

详细命令列表

systemctl start redis.service   #启动redis服务
systemctl stop redis.service   #停止redis服务
systemctl restart redis.service   #重新启动服务
systemctl status redis.service   #查看服务当前状态
systemctl enable redis.service   #设置开机自启动
systemctl disable redis.service   #停止开机自启动
