大家好，我是架构君，一个会写代码吟诗的架构师。今天说一说RedHat yum的配置[通俗易懂],希望能够帮助大家进步!!!
A sample /etc/yum.conf configuration file can look like this:
The following is a sample /etc/yum.repos.d/redhat.repo file:
enabled = 1 — Include this repository as a package source. gpgcheck and sslverify - 1 is true, 0 is false releasever You can use this variable to reference the release version of Red Hat Enterprise Linux. Yum obtains the value of releasever from the distroverpkg=value line in the /etc/yum.conf configuration file. If there is no such line in /etc/yum.conf, then yum infers the correct value by deriving the version number from the redhat-releaseproduct package that provides the redhat-release file.
basearch You can use basearch to reference the base architecture of the system. For example, i686 and i586 machines both have a base architecture of i386, and AMD64 and Intel 64 machines have a base architecture of x86_64.
issue 1，SSL certificate不通过
gpgkey和sslverify可以关掉再去执行。
issue 2，URL返回404
Check URL中的两个参数是否有效，将两个参数替换成有效的值（从其他可用yum的server获取）
假如$releasever没有在/etc/yum.conf中定义，运行yum version nogroups 获取
