1.下载redis压缩包

[http://download.redis.io/releases/redis-4.0.9.tar.gz][http_download.redis.io_releases_redis-4.0.9.tar.gz]（如果是其他版本的话可以直接修改后面的版本编号就可以）

2.将压缩包放在你需要安装的目录

![70][]

3 。解压 压缩包

cd /opt/  tar xzf redis-4.0.9.tar.gz

4.解压后 就会如上图一样 生成一个redus-4.0.10文件夹

5 cd /opt/redis-4.0.10/make（这里需要差不多20s）

6.等make 编译后 进入src 目录

分别执行下：  /opt/redis-4.0.10/src$ ./mkreleasehdr.sh

/opt/redis-4.0.10/src$ ./redis-benchmark

/opt/redis-4.0.10/src$ ./redis-check-aof

/opt/redis-4.0.10/src$ ./redis-cli

**/opt/redis-4.0.10/src$ ./redis-server**

7.应该会出现下面个图形界面

cd /usr/local/redis/bin/
    ./redis-server

    18847:M 28 May 19:14:10.120 # 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.

## 将redis作为linux service启动 ##

systemctl管理Redis启动、停止、开机启动

*  在/lib/systemd/system目录下创建一个脚本文件redis.service

vim /lib/systemd/system/redis.service
    
    #表示基础信息
    [Unit]
    #描述
    Description=Redis
    #在哪个服务之后启动
    After=syslog.target network.target remote-fs.target nss-lookup.target
    
    #表示服务信息
    [Service]
    Type=forking
    #和redis.conf配置文件中的信息一致
    PIDFile=/var/run/redis_6379.pid
    #启动服务的命令
    ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
    ExecReload=/bin/kill -s HUP $MAINPID
    ExecStop=/bin/kill -s QUIT $MAINPID
    PrivateTmp=true
    
    #安装相关信息
    [Install]
    WantedBy=multi-user.target
