配置本地yum源
删除默认repo文件
rm -rf /etc/yum.repos.d/*
vi /etc/yum.repos.d/Centos7.repo
[Centos7.9]
baseurl = file:///mnt/cdrom
gpgcheck = 0
enabled=1
name = Base Yum Repo
编译安装nginx
yum install gcc gcc-c++ pcre pcre-devel openssl openssl-devel -y
上传nginx-1.22.0.tar，解压并编译安装
./configure --user=www --group=www --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf
此时可用nginx直接配置
cd /etc/nginx/conf.d/
cat local_yum.conf
server {
listen 99;
server_name 本机IP;
charset utf-8;
location /cdrom
{
autoindex on;
root /mnt/;
}
}
浏览器访问http://本机IP:99/cdrom
使用createrepo实现
yum install -y createrepo
mkdir -p /mnt/nginx-yum
cp -a /mnt/cdrom/Packages/ /mnt/nginx-yum/ # /mnt/cdrom/为只读目录，且不想展示过多内容，需先拷贝出来
cd /mnt/nginx-yum/

#执行以下命令，利用挂载目录里的**comps.xml生成repodata，没有该文件将无法成功调用yum
#最终验证 直接拷贝/mnt/cdrom/repodata可直接使用，跟以下命令生成是一样的。这就很尴尬

原挂载的镜像此时也可以卸载，不影响使用
umount /mnt/cdrom/
