Redis集群部署方法

本篇內容介紹了“Redis集群部署方法”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！

1、主從節點均安裝好redis以及ruby。
[root@D2-LZY245 redis-4.0.1]# yum -y install ruby ruby-devel rubygems rpm-build
[root@D2-LZY245 redis-4.0.1]# gem install redis

2、主節點創建集群目錄、配置參數并啟動
[root@D2-LZY245 ~]# cd redis-4.0.1/
[root@D2-LZY245 redis-4.0.1]# mkdir redis_cluster
[root@D2-LZY245 redis-4.0.1]# cd redis_cluster/
[root@D2-LZY245 redis_cluster]# mkdir 7000 7001 7002
[root@D2-LZY245 redis_cluster]# cp ../redis.conf 7000/
[root@D2-LZY245 redis_cluster]# vim 7000/redis.conf
[root@D2-LZY245 redis_cluster]# egrep '^port|^bind|^daemonize|^pidfile|^cluster-enabled|^cluster-config-file|^cluster-node-timeout|^appendonly' 7000/redis_7000.conf
bind 10.163.89.245
port 7000
daemonize yes
pidfile /var/run/redis_7000.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 15000
[root@D2-LZY245 redis_cluster]# mv 7000/redis.conf  7000/redis_7000.conf
[root@D2-LZY245 redis_cluster]# cp 7000/redis_7000.conf 7001/redis_7001.conf
[root@D2-LZY245 redis_cluster]# cp 7000/redis_7000.conf 7002/redis_7002.conf
[root@D2-LZY245 redis_cluster]# vim 7001/redis_7001.conf
[root@D2-LZY245 redis_cluster]# egrep '^port|^bind|^daemonize|^pidfile|^cluster-enabled|^cluster-config-file|^cluster-node-timeout|^appendonly' 7001/redis_7001.conf
bind 10.163.89.245
port 7001
daemonize yes
pidfile /var/run/redis_7001.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-7001.conf
cluster-node-timeout 15000
[root@D2-LZY245 redis_cluster]# vim 7002/redis_7002.conf
[root@D2-LZY245 redis_cluster]# egrep '^port|^bind|^daemonize|^pidfile|^cluster-enabled|^cluster-config-file|^cluster-node-timeout|^appendonly' 7002/redis_7002.conf
bind 10.163.89.245
port 7002
daemonize yes
pidfile /var/run/redis_7002.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-7002.conf
cluster-node-timeout 15000

[root@D2-LZY245 redis_cluster]# cd ..
[root@D2-LZY245 redis-4.0.1]# src/redis-server redis_cluster/7000/redis_7000.conf
[root@D2-LZY245 redis-4.0.1]# src/redis-server redis_cluster/7001/redis_7001.conf
[root@D2-LZY245 redis-4.0.1]# src/redis-server redis_cluster/7002/redis_7002.conf
[root@D2-LZY245 redis-4.0.1]# netstat -tunlp | grep 700

4、創建集群
[root@D2-LZY245 redis-4.0.1]# src/redis-trib.rb create --replicas 1 10.163.89.245:7000 10.163.89.245:7001 10.163.89.245:7002 10.163.89.15:7003 10.163.89.15:7004 10.163.89.15:7005

[OK] All nodes agree about slots configuration.

5、測試
在主節點7000端口設置key：
[root@D2-LZY245 ~]# cd redis-4.0.1/
[root@D2-LZY245 redis-4.0.1]# src/redis-cli -h 10.163.89.245 -c -p 7000
10.163.89.245:7000> set key1 "hello world"
-> Redirected to slot [9189] located at 10.163.89.15:7003
OK
10.163.89.15:7003> keys *
1) "key1"

在從節點7005端口查看：
[root@D2-TRAIN15 redis-4.0.1]# src/redis-cli -h 10.163.89.15 -c -p 7005
10.163.89.15:7005> get key1
-> Redirected to slot [9189] located at 10.163.89.15:7003
"hello world"
