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]# 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.gzResolving 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 OKLength: 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.depHint: It's a good idea to run'make test' ;)INSTALL installINSTALL installINSTALL installINSTALL installINSTALL install
; “复制代码”)
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-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.

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.conf18713: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 redisroot 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 onservice 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 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
关闭：
方法 1：service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stopStopping ...Redis stopped
方法 2：redis-cli SHUTDOWN
