一、準備好 gcc 環境
yum?install?gcc-c++
出現以下日志，代表安裝成功。Package gcc-c++-4.8.5-39.el7.x86_64 already installed and latest version

二、下載并安裝redis
執行命令：wget http://download.redis.io/releases/redis-5.0.7.tar.gz。下載完成之后進行解壓。再先后執行 make、make install命令。
[root@root?/]#?cd?usr/java [root@root?java]#?mkdir?redis [root@root?java]#?cd?redis/ [root@root?redis]#?wget?http://download.redis.io/releases/redis-5.0.7.tar.gz [root@root?redis]#?tar?-zxvf?redis-5.0.7.tar.gz [root@root?redis]#?cd?redis-5.0.7 [root@root?redis-5.0.7]#?make [root@root?redis-5.0.7]#?make?install
三、啟動
輸入命令：redis-server redis.conf ，啟動Redis。看到以下頁面代表啟動成功。
[root@root?redis-5.0.7]#?redis-server?redis.conf ????????????????_._?????????????????????????????????????????????????? ???????????_.-``__?''-._????????????????????????????????????????????? ??????_.-``????`.??`_.??''-._???????????Redis?5.0.7?(00000000/0)?64?bit ??.-``?.-```.??```/????_.,_?''-._??????????????????????????????????? ?(????'??????,???????.-`??|?`,????)?????Running?in?standalone?mode ?|`-._`-...-`?__...-.``-._|'`?_.-'|?????Port:?6379 ?|????`-._???`._????/?????_.-'????|?????PID:?12513 ??`-._????`-._??`-./??_.-'????_.-'??????????????????????????????????? ?|`-._`-._????`-.__.-'????_.-'_.-'|?????????????????????????????????? ?|????`-._`-._????????_.-'_.-'????|???????????http://redis.io???????? ??`-._????`-._`-.__.-'_.-'????_.-'??????????????????????????????????? ?|`-._`-._????`-.__.-'????_.-'_.-'|?????????????????????????????????? ?|????`-._`-._????????_.-'_.-'????|?????????????????????????????????? ??`-._????`-._`-.__.-'_.-'????_.-'??????????????????????????????????? ??????`-._????`-.__.-'????_.-'??????????????????????????????????????? ??????????`-._????????_.-'??????????????????????????????????????????? ??????????????`-.__.-'
但是這種啟動沒有辦法在這個tab頁下做任何操作了，因為這個時候使用Ctrl+c之后，就變成了這個樣子。也就是關閉了Redis，這種方式是前臺啟動。
^C13082:signal-handler?(1594381754)?Received?SIGINT?scheduling?shutdown... 13082:M?10?Jul?2020?19:49:14.132?#?User?requested?shutdown... 13082:M?10?Jul?2020?19:49:14.132?*?Saving?the?final?RDB?snapshot?before?exiting. 13082:M?10?Jul?2020?19:49:14.135?*?DB?saved?on?disk 13082:M?10?Jul?2020?19:49:14.135?*?Removing?the?pid?file. 13082:M?10?Jul?2020?19:49:14.135?#?Redis?is?now?ready?to?exit,?bye?bye...
四、后臺啟動
打開redis.conf 文件。這也是Redis的配置文件。
[root@root?redis-5.0.7]#?vim?redis.conf? #打開之后，在命令窗口按下/輸入daem然后回車
修改為yes
daemonize?yes
Redis默認不是以守護進程的方式運行，可以通過該配置項修改，使用yes啟用守護進程，啟用守護進程后，Redis會把pid寫到一個pidfile中，在/var/run/redis_6379.pid文件中。
再次啟動
[root@root?redis-5.0.7]#?redis-server?redis.conf? 13352:C?10?Jul?2020?19:54:34.301?#?oO0OoO0OoO0Oo?Redis?is?starting?oO0OoO0OoO0Oo 13352:C?10?Jul?2020?19:54:34.301?#?Redis?version=5.0.7,?bits=64,?commit=00000000,?modified=0,?pid=13352,?just?started 13352:C?10?Jul?2020?19:54:34.301?#?Configuration?loaded
五、連接Redis
[root@root?redis-5.0.7]#?redis-cli? 127.0.0.1:6379>?ping PONG 127.0.0.1:6379>?config?get?requirepass #查看密碼 1)?"requirepass" 2)?"" 127.0.0.1:6379>
設置密碼
我們發現竟然不需要密碼就可以進入Redis。那怎么設置呢？
requirepass foobared：設置 Redis 連接密碼，如果配置了連接密碼，客戶端在連接 Redis 時需要通過 AUTH password命令提供密碼，默認是關閉。
1、臨時設置
config?set?requirepass?123456
2、永久設置
[root@root?redis-5.0.7]#?vim?redis.conf #打開之后，在命令窗口按下/輸入?requirepass?然后回車
找到如圖所示的內容，將注釋放開設置自己的密碼。
然后重啟Redis。
[root@root?redis-5.0.7]#?redis-server?redis.conf? [root@root?redis-5.0.7]#?redis-cli? 127.0.0.1:6379>?ping (error)?NOAUTH?Authentication?required. 127.0.0.1:6379>?auth?xxx OK 127.0.0.1:6379>?ping PONG 127.0.0.1:6379>
可以看到第一次ping的時候提示我需要身份驗證。auth xxx這是連接后輸入密碼。也可以在連接的時候輸入：
[root@root redis-5.0.7]# redis-cli -p 6379 -a xxx
