分散式安裝redis叢集
| 序號 | 主機 |
|---|---|
| 1 | 192.168.1.10 |
| 2 | 192.168.1.11 |
| 3 | 192.168.1.12 |
共搭建六個節點，每臺主機一主一從
分別在每臺主機上建立主從配置檔案
mkdir -p /data/redis-cluster # 建立主redis配置 touch /data/redis-cluster/redis01.conf cat << EOF > /data/redis-cluster/redis01.conf port 6381 bind 192.168.1.10 # bind 為宿主機IP cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes masterauth test123456 requirepass test123456 cluster-announce-ip 192.168.1.10 # 同是宿主機IP cluster-announce-port 6381 cluster-announce-bus-port 16381 EOF # 建立從redis配置 touch /data/redis-cluster/redis02.conf cat << EOF > /data/redis-cluster/redis02.conf port 6382 bind 192.168.1.10 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes masterauth test123456 requirepass test123456 cluster-announce-ip 192.168.1.10 cluster-announce-port 6381 cluster-announce-bus-port 16381 EOF
在不同主機建立redis容器
# 192.168.1.10 node01 node02 docker run -p 6381:6381 --name redis-node01 \ -v /data/redis-cluster/redis01.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf docker run -p 6382:6382 --name redis-node02 \ -v /data/redis-cluster/redis02.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf # 192.168.1.11 node01 node02 docker run -p 6381:6381 --name redis-node01 \ -v /data/redis-cluster/redis01.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf docker run -p 6382:6382 --name redis-node02 \ -v /data/redis-cluster/redis02.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf # 192.168.1.12 node01 node02 docker run -p 6381:6381 --name redis-node01 \ -v /data/redis-cluster/redis01.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf docker run -p 6382:6382 --name redis-node02 \ -v /data/redis-cluster/redis02.conf:/etc/redis/redis.conf \ --net host --restart=always \ -d redis:6.2 redis-server /etc/redis/redis.conf
Could not connect to Redis at 192.168.1.10:6381: Connection refused
--net host 在不同主機搭建redis叢集的話，就需要新增該配置。不然無法找到redis其他主機上的叢集
搭建redis叢集
在任一主機redis容器內使用命令建立叢集
docker exec -it redis-node01 /bin/bash # -a test123456 redis設定密碼之後需要指定密碼 redis-cli --cluster create 192.168.1.18:6381 192.168.1.18:6382 192.168.1.83:6381 192.168.1.83:6382 192.168.1.182:6381 192.168.1.182:6382 --cluster-replicas 1 -a test123456 # 選項 填yes Can I set the above configuration? (type 'yes' to accept): yes # 檢視叢集狀態 redis-cli -c -h 192.168.1.10 -p 6381 -a test123456 cluster nodes
