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@iZwz991stxdwj560bfmadtZ 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
[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
第三步：yum安裝gcc依賴
yum install gcc
[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc
遇到選擇,輸入y即可
cd redis-4.0.6第四步：跳轉到redis解壓目錄下
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
第五步：編譯安裝
make MALLOC=libc
[root@iZwz991stxdwj560bfmadtZ redis]# 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@iZwz991stxdwj560bfmadtZ redis]# 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、啓動redis的三種方式
先切換到redis src目錄下
[root@iZwz991stxdwj560bfmadtZ redis]# cd src
1、直接啓動redis
./redis-server
[root@iZwz991stxdwj560bfmadtZ 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

18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. 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
如上圖：redis啓動成功，但是這種啓動方式需要一直打開窗口，不能進行其他操作，不太方便。
按 ctrl + c可以關閉窗口。
2、以後臺進程方式啓動redis
第一步：修改redis.conf文件
將
daemonize no
修改爲
daemonize yes
第二步：指定redis.conf文件啓動

|
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis/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@iZwz991stxdwj560bfmadtZ 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
這裏的進程號可能不一樣的
3、設置redis開機自啓動
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 文件複製一份到/etc/redis目錄下，並命名爲6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
這裏一定得是6379.conf
3、將redis的啓動腳本複製一份放到/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開機自啓動
先切換到/etc/init.d目錄下
然後執行自啓命令
[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註釋，保存退出
# chkconfig: 2345 90 10 # description: Redis is a persistent key-value database
註釋的意思是，redis服務必須在運行級2，3，4，5下被啓動或關閉，啓動的優先級是90，關閉的優先級是10。
再次執行開機自啓命令，成功
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
現在可以直接已服務的形式啓動和關閉redis了
啓動：
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
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop Stopping ... Redis stopped

如果出現如下問題：
[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start /var/run/redis_6379.pid exists, process is already running or crashed
