系統(tǒng)版本：CentOS 6.8 x86_64（適用于CentOS 7.*） gcc 版本 4.4.7 redis版本：4.0.8 安裝方式：源碼安裝redis 軟件包路徑：/opt/tools/ 安裝路徑：/usr/local/
Ruby環(huán)境（集群搭建需要用ruby創(chuàng)建, ruby環(huán)境在2.2以上。） rubygems：ruby的一個(gè)包管理工具 redis.gem ：redis集群需要的ruby插件，通過(guò)rubygems安裝redis-4.0.1.gem。
[root@redis_1 ~]# cd /opt/tools/ [root@redis_1 tools ]# wget http://download.redis.io/releases/redis-4.0.8.tar.gz [root@redis_1 tools ]# tar xf redis-4.0.8.tar.gz -C /usr/local/ [root@redis_1 tools ]# cd /usr/local/redis-4.0.8/ [root@redis_1 redis-4.0.8 ]# make [root@redis_1 redis-4.0.8 ]# make install
編譯完成后會(huì)在src目錄下生成Redis服務(wù)端程序redis-server和客戶端程序redis-cli。
[root@redis_1 redis-4.0.8 ]# redis-server
該方式啟動(dòng)默認(rèn)為前臺(tái)方式運(yùn)行，使用默認(rèn)配置。
可以修改redis.conf文件的daemonize參數(shù)為yes，指定配置文件啟動(dòng)，例如：
[root@redis_1 redis-4.0.8 ]# cp -a redis.conf{,_$(date +%F)}
[root@redis_1 redis-4.0.8 ]# vim redis.conf
# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes
或者執(zhí)行sed替換命令：
[root@redis_1 redis-4.0.8 ]# sed -i 's#daemonize no#daemonize yes#g' redis.conf
[root@redis_1 redis-4.0.8 ]# grep 'daemonize yes' redis.conf
daemonize yes指定配置文件啟動(dòng)。
[root@redis_1 redis-4.0.8 ]# redis-server redis.conf
停止后臺(tái)啟動(dòng)的redis-server進(jìn)程：
[root@redis_1 redis-4.0.8 ]# redis-cli -h $(hostname -i) -c -p ${端口}
192.168.1.101:7000> SHUTDOWN
not connected> exit例如：
# 指定配置文件后臺(tái)啟動(dòng)

更多啟動(dòng)參數(shù)如下：
[root@redis_1 src]# ./redis-server --help Usage: ./redis-server [/path/to/redis.conf] [options] ./redis-server - (read config from stdin) ./redis-server -v or --version ./redis-server -h or --help ./redis-server --test-memory <megabytes> Examples: ./redis-server (run the server with default conf) ./redis-server /etc/redis/6379.conf ./redis-server --port 7777 ./redis-server --port 7777 --slaveof 127.0.0.1 8888 ./redis-server /etc/myredis.conf --loglevel verbose Sentinel mode: ./redis-server /etc/sentinel.conf --sentinel
[root@redis_1 redis-4.0.8]# src/redis-cli redis> set foo bar OK redis> get foo "bar"
Redis的集群部署需要在每臺(tái)集群部署的機(jī)器上安裝Redis；可參考上述的Redis部署，然后修改配置以集群的方式啟動(dòng)。 我們要在單臺(tái)機(jī)器上搭建Redis集群，方式是通過(guò)不同的TCP端口啟動(dòng)多個(gè)實(shí)例，然后組成集群。 需要注意的是：必須要3個(gè)或以上的主節(jié)點(diǎn)，否則在創(chuàng)建集群時(shí)會(huì)失敗，并且當(dāng)存活的主節(jié)點(diǎn)數(shù)小于總節(jié)點(diǎn)數(shù)的一半時(shí)，整個(gè)集群就無(wú)法提供服務(wù)了。 最小集群模式需要三個(gè)master實(shí)例，一般建議起六個(gè)實(shí)例，即三主三從。因此我們創(chuàng)建6個(gè)以端口號(hào)命名的目錄存放實(shí)例的配置文件和其他信息。
[root@redis_1 redis-4.0.8]# mkdir -pv redis-cluster/{7000,7001,7002,7003,7004,7005}
[root@redis_1 redis-4.0.8]# cd redis-cluster/7000在對(duì)應(yīng)端口號(hào)的目錄中創(chuàng)建redis.conf的文件，配置文件的內(nèi)容可參考如下的集群模式配置。每個(gè)配置文件中的端口號(hào)port參數(shù)改為對(duì)應(yīng)目錄的端口號(hào)。 修改配置文件redis.conf，集群模式的配置文件如下：
[root@redis_1 7000]# vim redis.conf daemonize yes //redis后臺(tái)運(yùn)行； port 7000 //端口7000,7001,7002,7003,7004,7005； timeout 600 // 客戶端無(wú)響應(yīng)連接超時(shí)時(shí)間；默認(rèn)關(guān)閉 bind 192.168.1.91 //默認(rèn)ip為127.0.0.1 需要改為其他節(jié)點(diǎn)機(jī)器可訪問(wèn)的ip 否則創(chuàng)建集群時(shí)無(wú)法訪問(wèn)對(duì)應(yīng)的端口，無(wú)法創(chuàng)建集群； pidfile /var/run/redis_7000.pid //pidfile文件對(duì)應(yīng)7000,7001,7002,7003,7004,7005； cluster-enabled yes //開(kāi)啟集群 把注釋#去掉； cluster-config-file nodes_7000.conf //集群的配置 配置文件首次啟動(dòng)自動(dòng)生成 7000,7001,7002,7003,7004,7005 ； cluster-node-timeout 15000 //請(qǐng)求超時(shí) 默認(rèn)15秒，可自行設(shè)置； appendonly yes //aof日志開(kāi)啟 有需要就開(kāi)啟，每次寫(xiě)操作都記錄一條日志； # 查看 [root@redis_1 7000]# egrep "^daemonize|^port|^timeout|^bind|^pidfile|^cluster-|^appendonly" redis.conf
更多集群配置參數(shù)可參考默認(rèn)配置文件redis.conf中Cluster模塊的說(shuō)明。
復(fù)制redis-server的二進(jìn)制文件到redis-cluster目錄中，通過(guò)指定配置文件的方式啟動(dòng)redis服務(wù)，例如：
[root@redis_1 7000]# pwd /usr/local/redis-4.0.8/redis-cluster/7000 [root@redis_1 7000]# redis-server ./redis.conf # 需在指定實(shí)例目錄中執(zhí)行文件，會(huì)在命令當(dāng)前目錄生成文件。 2497:C 18 May 13:42:24.279 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 2497:C 18 May 13:42:24.279 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=2497, just started 2497:C 18 May 13:42:24.279 # Configuration loaded
如果是以前臺(tái)方式運(yùn)行，則會(huì)在控制臺(tái)輸出以下信息：
[82462] 26 Nov 11:56:55.329 * No cluster configuration found, I'm 97a3a64667477371c4479320d683e4c8db5858b1
每個(gè)實(shí)例都會(huì)生成一個(gè)Node ID，類似97a3a64667477371c4479320d683e4c8db5858b1，用來(lái)作為Redis實(shí)例在集群中的唯一標(biāo)識(shí)，而不是通過(guò)IP和Port，IP和Port可能會(huì)改變，該Node ID不會(huì)改變。 目錄結(jié)構(gòu)可參考：
redis-cluster/ ├── 7000 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── 7001 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── 7002 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── 7003 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── 7004 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── 7005 │ ├── appendonly.aof │ ├── dump.rdb │ ├── nodes.conf │ └── redis.conf ├── redis-cli └── redis-server
注：其中dump.rdb為數(shù)據(jù)存放文件，第一次啟動(dòng)集群時(shí)沒(méi)有。 Redis的實(shí)例全部運(yùn)行之后，還需要redis-trib.rb工具來(lái)完成集群的創(chuàng)建，redis-trib.rb二進(jìn)制文件在Redis包主目錄下的src目錄中，運(yùn)行該工具依賴Ruby環(huán)境和gem。
說(shuō)明：下面步驟3和步驟4針對(duì)不同環(huán)境，服務(wù)器可以連外網(wǎng)推薦步驟3，無(wú)法連外網(wǎng)推薦步驟4源碼安裝依賴包，安裝一個(gè)即可。

方式一：修改所有Redis集群中的redis.conf文件加入：
masterauth passwd123 requirepass passwd123
說(shuō)明：這種方式需要重新啟動(dòng)各節(jié)點(diǎn) 方式二：進(jìn)入各個(gè)實(shí)例進(jìn)行設(shè)置：redis-cli -h $IP -c -p 端口
./redis-cli -c -p 7000 config set masterauth passwd123 config set requirepass passwd123 config rewrite
之后分別使用./redis-cli -c -p 7001，./redis-cli -c -p 7002…..命令給各節(jié)點(diǎn)設(shè)置上密碼。 注意：各個(gè)節(jié)點(diǎn)密碼都必須一致，否則Redirected就會(huì)失敗， 推薦這種方式，這種方式會(huì)把密碼寫(xiě)入到redis.conf里面去，且不用重啟。 用方式二修改密碼，./redis-trib.rb check 10.104.111.174:6379執(zhí)行時(shí)可能會(huì)報(bào)[ERR] Sorry, can't connect to node 10.104.111.174:6379，因?yàn)?379的redis.conf沒(méi)找到密碼配置。
如：./redis-trib.rb check 127.0.0.1:7000，則會(huì)報(bào)錯(cuò)ERR] Sorry, can’t connect to node 127.0.0.1:7000 解決辦法：
vim /usr/local/rvm/gems/ruby-2.3.0/gems/redis-4.0.1/lib/redis/client.rb # 聯(lián)網(wǎng)安裝路徑 vim /usr/local/lib/ruby/gems/2.3.0/gems/redis-4.0.1/lib/redis/client.rb # 源碼安裝路徑
注意：client.rb路徑可以通過(guò)find命令查找：find / -name 'client.rb' 然后修改passord
