1、安裝redis

第一步：下載redis安裝包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

[[email protected] 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

[[email protected] local]# tar -zxvf redis-4.0.6.tar.gz

　

第三步：yum安裝gcc依賴

yum install gcc

[[email protected] local]# yum install gcc 

第四步：跳轉到redis解壓目錄下

cd redis-4.0.6

[[email protected] local]# cd redis-4.0.6

 

第五步：編譯安裝

make MALLOC=libc　　

[[email protected] redis-4.0.6]# make MALLOC=libc

將/usr/local/redis-4.0.6/src目錄下的檔案加到/usr/local/bin目錄

cd src && make install

[[email protected] 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

　　

第六步：測試是否安裝成功 

先切換到redis src目錄下

[[email protected] redis-4.0.6]# cd src

1、直接啟動redis

./redis-server

123456789101112131415161718192021222324252627

[[email protected] src]# ./redis-server18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config.

This will create latency and memory usage issues with Redis. To fix this issue run the command ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled‘ as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.18685:M 13 Dec 12:56:12.508 * Ready to accept connections

 

如：redis啟動成功，但是這種啟動方式需要一直開啟視窗，不能進行其他動作，不太方便。

 

按 ctrl + c可以關閉視窗。

　　

2、以後台進程方式啟動redis

第一步：修改redis.conf檔案

將

daemonize no

修改為

daemonize yes

　　

第二步：指定redis.conf檔案啟動

./redis-server /usr/local/redis-4.0.6/redis.conf [[email protected] 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

[[email protected] 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

[[email protected] src]# kill -9 18714

　　

　　　

 

第七步：設定redis開機自啟動

1、在/etc目錄下建立redis目錄

mkdir redis

[[email protected] etc]# mkdir redis

 

2、將/usr/local/redis-4.0.6/redis.conf 檔案複製一份到/etc/redis目錄下，並命名為6379.conf　　

[[email protected] redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf

　　

3、將redis的啟動指令碼複製一份放到/etc/init.d目錄下

[[email protected] init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd

　　

4、設定redis開機自啟動

先切換到/etc/init.d目錄下

然後執行自啟命令

[[email protected] init.d]# chkconfig redisd on service redisd does not support chkconfig　

看結果是redisd不支援chkconfig

解決方案：

使用vim編輯redisd檔案，在第一行加入如下兩行注釋，儲存退出

# 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，啟動的優先順序是90，關閉的優先順序是10。

 

再次執行開機自啟命令，成功

[[email protected] 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　　

[[email protected] ~]# 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

[[email protected] ~]# service redisd stop Stopping ... Redis stopped
