linux 发行版 Centos 7 安装redis 6.0.4

安装前准备

1. 一个网络OK的Centos 7环境。这里我们选择在window上安装，VMWare的虚拟机。
2. 远程操作linux的工具，这里我们选择比较简单的 SecureCRT

第一步 下载

进入到 /usr/local/ 目录下执行下载指令:

$ wget http://download.redis.io/releases/redis-6.0.4.tar.gz

第二步 解压

$ tar xzf redis-6.0.4.tar.gz

第三步 编译

因为我们下载的是redis的源代码，用C语言编写的，需要编译后才可以在操作系统上安装。

$ cd redis-6.0.4
$ make

eg：这里有个坑
编译报错如下:

server.c:5099:19: error: ‘struct redisServer’ has no member named ‘ipfd_count’
         if (server.ipfd_count > 0 || server.tlsfd_count > 0)

解决办法：
查看gcc版本是否在5.3以上，CentOS7默认安装4.8.5。
升级gcc到5.3以上版本，升级到gcc 9
具体可以参考这位大佬的 文章.

第四步 启动

$ src/redis-server

如下图，就说明成功启动了

第五步 退出

采用客户端连接到服务端，执行shutdown命令的这种方式退出

$ ./redis-cli
127.0.0.1:6379> shutdown nosave
