一、安裝redis
第一步：下載redis安裝包
wget http://download.redis.io/releases/redis-4.0.6.tar.gz
[root@VM_34_108_centos local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz --2017-12-13 12:35:12-- http://download.redis.io/releases/redis-4.0.6.tar.gz Resolving download.redis.io (download.redis.io)... 109.74.203.151 Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1723533 (1.6M) [application/x-gzip] Saving to: ‘redis-4.0.6.tar.gz’ 100%[==========================================================================================================>] 1,723,533 608KB/s in 2.8s 2017-12-13 12:35:15 (608 KB/s) - ‘redis-4.0.6.tar.gz’ saved [1723533/1723533]
第二步：解壓壓縮包
tar -zxvf redis-4.0.6.tar.gz
第三步：yum安裝gcc依賴
yum install gcc
第四步：跳轉到redis解壓目錄下
cd redis-4.0.6
第五步：編譯安裝
make MALLOC=libc
將/usr/local/redis-4.0.6/src目錄下的文件加到/usr/local/bin目錄
cd src && make install
[root@VM_34_108_centos redis-4.0.6]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
二、啟動redis的三種方式
先切換到redis src目錄下（redis安裝目錄）
1、直接啟動redis
./redis-server
[root@VM_34_108_centos src]# ./redis-server
18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started
18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

Redis must be restarted after THP is disabled.

2、以后台進程方式啟動redis
第一步：修改redis.conf文件
將deamonize no 改為 yes
第二步：指定redis.conf文件啟動
./redis-server /usr/local/redis-4.0.6/redis.conf
[root@VM_34_108_centos src]# ./redis-server /usr/local/redis-4.0.6/redis.conf 18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started 18713:C 13 Dec 13:07:41.109 # Configuration loaded
第三步：關閉redis進程
首先使用ps -aux | grep redis查看redis進程
[root@VM_34_108_centos src]# ps -aux | grep redis root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379 root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
使用kill命令殺死進程
[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714
3、設置redis開機自啟動
1、在/etc目錄下新建redis目錄
mkdir redis
[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
2、將/usr/local/redis-4.0.6/redis.conf 文件復制一份到/etc/redis目錄下，並命名為6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
3、將redis的啟動腳本復制一份放到/etc/init.d目錄下
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
4、設置redis開機自啟動
先切換到/etc/init.d目錄下
然后執行自啟命令
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on service redisd does not support chkconfig
看結果是redisd不支持chkconfig
解決方法：
使用vim編輯redisd文件，在第一行加入如下兩行注釋，保存退出
# chkconfig: 2345 90 10 # description: Redis is a persistent key-value database
注釋的意思是，redis服務必須在運行級2，3，4，5下被啟動或關閉，啟動的優先級是90，關閉的優先級是10。
再次執行開機自啟命令，成功
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
現在可以直接已服務的形式啟動和關閉redis了
啟動：
service redisd start
[root@izwz991stxdwj560bfmadtz ~]# service redisd start Starting Redis server... 2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started 2288:C 13 Dec 13:51:38.087 # Configuration loaded
關閉：
service redisd stop
3、配置外網訪問
更改redis.conf 文件
將 #bind 127.0.0.1 改為 bind 127.0.0.1
將protected-mode yes 改為 protected-mode no
重啟redis服務即可
