【Redis】Redis各大版本最新版以及系统兼容性测试

        目前Redis总共有四个大版本提供下载，分别是：5.0.xx、6.0.xx、6.2.xx、7.0.xx

        下载地址如下：

• Download 7.0.5
• download 6.2.7
• download 6.0.16
• download 5.0.14

        本次安装测试使用的系统为 CentOS 7.9 x86_64，在安装之前，需要预先安装GCC环境，在线安装命令如下：

# yum install -y gcc gcc-c++

Downloading packages:                                
(1/9): glibc-devel-2.17-326.el7_9.x86_64.rpm         
(2/9): cpp-4.8.5-44.el7.x86_64.rpm                   
(3/9): libmpc-1.0.1-3.el7.x86_64.rpm                 
(4/9): libstdc++-devel-4.8.5-44.el7.x86_64.rpm       
(5/9): gcc-c++-4.8.5-44.el7.x86_64.rpm               
(6/9): mpfr-3.1.1-4.el7.x86_64.rpm                   
(7/9): kernel-headers-3.10.0-1160.76.1.el7.x86_64.rpm
(8/9): glibc-headers-2.17-326.el7_9.x86_64.rpm       
(9/9): gcc-4.8.5-44.el7.x86_64.rpm                   

备注：如果服务器在内网，则需要预先将这些安装包（包括依赖包）下载下来，再安装。

GCC环境安装好后，逐个解压上面下载的四个版本包，然后分别进入安装包中执行编译

# make

备注：为了测试，make install 可先不执行。

        测试结果让我感觉有点意外，在CentOS 7.9系统中，Redis 5.0.14、6.2.7、7.0.5这三个版本可以成功编译、安装和运行，但是6.0.16版本，在CentOS7.9上编译失败，网上查询资料，应该与CentOS7自带的GCC的版本过低有关。
