腾讯云服务器OpenCloudOS 9使用yum无法安装nginx

1. 报错

[root@VM-24-15-opencloudos yum.repos.d]# yum install nginx
Last metadata expiration check: 0:00:15 ago on Thu 31 Oct 2024 04:35:41 PM CST.
All matches were filtered out by exclude filtering for argument: nginx
Error: Unable to find a match: nginx

2. 解决方案

• 原因：通常是因为 yum 的配置中存在一个 exclude 过滤器，阻止了 nginx 包的安装。

• 解决方案：

  1. 检查 /etc/yum.conf 文件中的 exclude 设置

  cat /etc/yum.conf | grep exclude
  

  

  2. 清理缓存并尝试安装

  sudo yum clean all 
  sudo yum makecache 
  sudo yum install nginx
