今天想着是要重新配置一下我的Centos8虚拟机，目的是为了以后搭自己的博客有一个站点，同时在自己电脑上使劲造，也不用怕学校服务器出事怪到我头上。
于是就开始了下面这一步：
# 启动httpd服务
systemctl start httpd.service
运行上述命令的时候，会出现如下报错
Failed to start httpd.service: Unit httpd.service not found.
然后，就想着用yum安装httpd，然而。。。
yum install httpd -y
# 报错信息如下：
CentOS Linux 8 - AppStream 0.0 B/s | 0 B 01:27
Errors during downloading metadata for repository 'appstream':
- Curl error (7): Couldn't connect to server for http://vault.centos.org/centos/8/AppStream/x86_64/os/repodata/repomd.xml [Failed to connect to vault.centos.org port 80: Connection refused]
Error: Failed to download metadata for repo 'appstream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
再后续，就在看这个博客了：
centos8重新配置yum源(Errors during downloading metadata for repository ‘AppStream‘)
我也去阿里云社区凑凑热闹，发现Centos 8以后就停止维护了，如下：

但是现在还是将就着用吧（毕竟维护啥的，我又不是开发人员）
cd /etc/yum.repos.d/
# 查看已存在的repo
ls -l
# 备份原有repo
mkdir bakup
mv *repo bakup/
# 下载最近repo
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
# 查看下载的repo
ll
# [train@Centos8(4.4) /etc/yum.repos.d]$ ls -lh
# total 8.0K
# drwxr-xr-x. 2 root root 4.0K Mar 4 22:19 bakup
# -rw-r--r--. 1 root root 2.5K Feb 14 21:16 CentOS-Base.repo
# 运行 yum makecache 生成缓存
yum makecache
# CentOS-8.5.2111 - Base - mirrors.aliyun.com 1.5 MB/s | 4.6 MB 00:03
# CentOS-8.5.2111 - Extras - mirrors.aliyun.com 63 kB/s | 10 kB 00:00
# CentOS-8.5.2111 - AppStream - mirrors.aliyun.com 271 kB/s | 8.4 MB 00:31
# Last metadata expiration check: 0:00:01 ago on Fri 04 Mar 2022 10:20:24 PM CST.
# Metadata cache created.
现在就可以正常使用yum命令了
sudo yum install httpd
# 启用网站服务
systemctl start httpd.service
# 设置服务开机启动
systemctl enable httpd.service
