1.查看CentOS版本號
[root@localhost redis-cluster]# uname -a
Linux localhost.localdomain 3.10.0-957.10.1.el7.x86_64 #1 SMP Mon Mar 18 15:06:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost redis-cluster]# rpm -q centos-release
centos-release-7-6.1810.2.el7.centos.x86_64
2.下載和解包
[root@localhost local]# cd software
[root@localhost software]# wget http://download.redis.io/releases/redis-4.0.2.tar.gz

2.安裝gcc環境
由於Redis是由C語言編寫的，它的運行需要C環境，因此需要先安裝gcc。安裝命令是yum install gcc-c++
3.編譯安裝
我們到/usr/local/redis-4.0.2目錄下，要運行make和make install命令就要有Makefile這個文件，我們可以看到是有這個文件的。
[root@localhost local]# cd /usr/local/redis-4.0.2
[root@localhost redis-4.0.2]# ll

drwxrwxr-x. 8 root root 4096 Sep 21 2017 utils
[root@localhost redis-4.0.2]#
4.先進行編譯
[root@localhost redis-4.0.2]# make
5.在進行安裝
[root@localhost redis-4.0.2]# make install PREFIX=/usr/local/redis
安裝完之後，我們到/usr/local目錄下，可以看到redis目錄，我們進入redis目錄，在該目錄下可以看到bin目錄，進入到bin目錄可以看到redis的客戶端和服務端，如下所示。
6.啓動redis服務端
第一種啓動方式是直接使用./redis-server命令啓動，如下所示（可以看到默認端口是6379），只不過這種啓動會佔用終端，如果我們按Ctrl+C就會停止redis-server。
[root@localhost bin]# ./redis-server
36770:C 13 Apr 17:21:27.055 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

第二種啓動方式是使用配置文件啓動（也叫後端啓動），我們需要先到redis的安裝目錄下把redis.conf文件複製一份到/usr/local/redis/bin目錄下。如下所示。

[root@localhost bin]#
下面我們需要簡單修改下redis.conf文件，把daemonize的值由默認的no修改爲yes，這個配置是指定是否在後臺運行。如下圖所示。
下面使用後臺啓動
[root@localhost bin]# ./redis-server redis.conf
要想查看是否正常啓動了，可以使用ps -ef|grep redis或ps aux | grep redis，如下所示，可以看到已經正常啓動了。
[root@localhost bin]# ps -ef|grep redis
root 11056 1 0 04:35 ? 00:00:00 ./redis-server 127.0.0.1:6379
root 11061 10933 0 04:35 pts/0 00:00:00 grep --color=auto redis
至此redis的安裝完成了
下面開始搭建集羣
