http://yum.redflag-linux.com/ax7sp6/x86_64/base/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: yum.redflag-linux.com; 未知的错误"
正在尝试其它镜像。
One of the configured repositories failed (Redflag x86_64 Linux 7 - Base),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=redflag-base ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage
yum-config-manager --disable redflag-base
or
subscription-manager repos --disable=redflag-base
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=redflag-base.skip_if_unavailable=true
failure: repodata/repomd.xml from redflag-base: [Errno 256] No more mirrors to try.

1.2 再次检查确认
[app@localhost gcc-9.2.0]$ gcc --version
bash: gcc: 未找到命令…
[root@localhost gcc-9.2.0]# whereis gcc
gcc:[root@localhost gcc-9.2.0]#
[root@localhost bin]# which gcc
/usr/bin/which: no gcc in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/app/.local/bin:/home/app/bin)
确实没有，那只能自己处理了，由于没有权限，只能找大佬要yum源，自己绑定和安装
2 绑定yum源文件
2.1 注掉原来的源文件
[root@localhost usr]# cd /etc/yum.repos.d/
mv redflag.repo redflag.repobak
2.2 重新编写新的源文件
vim Asianux_server7.6.repo
添加了以下内容：
[Asianux7.6]
name=Asianux7.6
baseurl=http://*.*.*.*/Asianux7.6
enabled=1
gpgcheck=0
gpgkey=http://*.*.*.*/Asianux7.6/RPM-GPG-KEY-Asianux7 (*.*.*.* 具体的ip地址)
2.3 清缓存
yum clean all 清缓存
yum makecache 拉缓存
yum repolist 验证yum源
2.4 安装gcc
[root@localhost postgresql-13.5]# yum -y install gcc*
