一、安装redis
第一步：下载redis安装包
wget http://download.redis.io/releases/redis-4.0.6.tar.gz
[root@iZwz991stxdwj560bfmadtZ local]#wgethttp://download.redis.io/releases/redis-4.0.6.tar.gz--2017-12-1312:35:12-- http://download.redis.io/releases/redis-4.0.6.tar.gzResolving download.redis.io (download.redis.io)...109.74.203.151Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected.

第二步：解压压缩包
[root@iZwz991stxdwj560bfmadtZ local]#tar -zxvf redis-4.0.6.tar.gz
第三步：yum安装gcc依赖
[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
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
第五步：编译安装
[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
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'maketest' ;)
INSTALL install
INSTALL install
INSTALL install
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
[root@iZwz991stxdwj560bfmadtZ src] ./redis-server

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 ### /home/admin/soft/redis-4.0.6
将 daemonize no 修改为 daemonize yes
第二步：指定redis.conf文件启动 ### ./redis-server /home/admin/soft/redis-4.0.6/redis.conf
[root@iZwz991stxdwj560bfmadtZ src] ./redis-server /usr/local/redis-4.0.6/redis.conf
18713:C13Dec13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18713:C13Dec13:07:41.109# Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started
18713:C13Dec13:07:41.109# 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 187140.00.11417522008? Ssl13:070:00./redis-server127.0.0.1:6379
root 187190.00.0112644968pts/0R+13:090:00grep--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 ### cd /etc/
[root@iZwz991stxdwj560bfmadtZ etc]# sudo 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]# sudo cp /home/admin/soft/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]
sudo cp /home/admin/soft/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 ### sudo vim redisd
# chkconfig:23459010
# 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 ### sudo chkconfig redisd on
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
现在可以直接以服务的形式启动和关闭redis了
启动：
[root@izwz991stxdwj560bfmadtz ~] service redisd start
Starting Redis server...
2288:C13Dec13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
2288:C13Dec13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started
2288:C13Dec13:51:38.087 # Configuration loaded
关闭：
方法1：service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop
Stopping ...
Redis stopped
方法2：redis-cli SHUTDOWN
