具体安装步骤如下：
一、安装redis
第一步：下载redis安装包
[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：解压压缩包
tar -zxvf redis-4.0.6.tar.gz [root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
第三步：yum安装gcc依赖
yum install gcc [root@iZwz991stxdwj560bfmadtZ local]# yum install gcc
遇到选择,输入y即可
第四步：跳转到redis解压目录下
cd redis-4.0.6 [root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
第五步：编译安装
make MALLOC=libc [root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc
将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录
cd src && make install
[root@iZwz991stxdwj560bfmadtZ 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二、启动redis的三种方式
先切换到redis src目录下
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
1、直接启动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 yo
u 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
如上图：redis启动成功，但是这种启动方式需要一直打开窗口，不能进行其他操作，不太方便。
按 ctrl + c可以关闭窗口。
2、以后台进程方式启动redis
第一步：修改redis.conf文件
将
daemonize no
修改为
daemonize yes
第二步：指定redis.conf文件启动
./redis-server /usr/local/redis-4.0.6/redis.conf [root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf 18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started18713:C 13 Dec 13:07:41.109 # Configuration loaded
第三步：关闭redis进程
首先使用ps -aux | grep redis查看redis进程
[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
使用kill命令杀死进程
[root@iZwz991stxdwj560bfmadtZ src]# kill 18714
3、设置redis开机自启动
1、在/etc目录下新建redis目录
mkdir redis [root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
2、将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
3、将redis的启动脚本复制一份放到/etc/init.d目录下
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
4、设置redis开机自启动
先切换到/etc/init.d目录下
然后执行自启命令
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on service redisd does not support chkconfig
看结果是redisd不支持chkconfig
解决方法：
使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出
# chkconfig: 2345 90 10# description: Redis is a persistent key-value database
注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10
再次执行开机自启命令，成功
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
现在可以直接已服务的形式启动和关闭redis了
启动：
service redisd start [root@izwz991stxdwj560bfmadtz ~]# service redisd startStarting Redis server...2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started2288:C 13 Dec 13:51:38.087 # Configuration loaded
关闭：
方法1：service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop Stopping ... Redis stopped
方法2：redis-cli SHUTDOWN

如果出现如下问题：
[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start/var/run/redis_6379.pid exists, process is already running or crashed
