Redis-5.0.5集群環境

從redis官網下載(http://download.redis.io/releases/redis-5.0.5.tar.gz)最新版本的redis的源碼包redis-5.0.5.tar.gz。 安裝redis 創建目錄/home/test/redis，上傳redis包并解壓縮 [root@test local]#mkdir -p /home/test/redis 將redis-5.0.5.tar.gz上傳到服務器的/home/test/redis目錄下 [root@test local]#cd /home/test/redis [root@test local]#tar -xzf redis-5.0.5.tar.gz 編譯安裝 執行命令make && make install [root@test redis]# cd redis-5.0.5 [root@test redis]# make && make install 創建集群目錄 在/home/test/redis目錄下創建集群目錄 [root@test redis]# mkdir redis-cluster [root@test redis]# cd redis-cluster/ 在集群目錄下創建節點目錄 小編的示例中是在單臺服務器安裝9個節點，所以下面創建9個目錄 [root@test redis-cluster]# mkdir 7000 7001 7002 7003 7004 7005 7006 7007 7008 [root@test redis-cluster]# ls 7000 7001 7002 7003 7004 7005 7006 7007 7008 集群中的節點配置文件修改 把如下redis.conf 配置內容粘貼進去 [root@test local]#vi 7000/redis.conf [root@test local]#vi 7001/redis.conf [root@test local]#vi 7002/redis.conf [root@test local]#vi 7003/redis.conf [root@test local]#vi 7004/redis.conf [root@test local]#vi 7005/redis.conf [root@test local]#vi 7006/redis.conf [root@test local]#vi 7007/redis.conf [root@test local]#vi 7008/redis.conf redis.conf 配置 #端口7000,7001,7002 port 7000 #默認ip為127.0.0.1，需要改為其他節點機器可訪問的ip，否則創建集群時無法訪問對應的端口，無法創建集群 bind 172.30.14.240 #redis后臺運行 daemonize yes #pidfile文件對應7000，7001，7002… pidfile /var/run/redis_7000.pid #開啟集群，把注釋#去掉 cluster-enabled yes #集群的配置，配置文件首次啟動自動生成 7000，7001，7002 cluster-config-file nodes_7000.conf #請求超時，默認15秒，可自行設置 cluster-node-timeout 10100 Eof日志開啟，有需要就開啟，它會每次寫操作都記錄一條日志 appendonly yes 集群中的節點啟動 /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7000/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7001/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7002/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7003/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7004/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7005/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7006/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7007/redis.conf /home/test/redis/redis-5.0.5/src/redis-server /home/test/redis/redis-cluster/7008/redis.conf 出現以下信息，表示啟動成功： 41846:C 24 Oct 10:51:47.070 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 41846:C 24 Oct 10:51:47.070 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=41846, just started 41846:C 24 Oct 10:51:47.070 # Configuration loaded 檢查服務 [root@test redis-cluster]# ps -ef | grep redis root 41396 1 0 10:51 ?
