看到这个都是情非得已的，话不多说，直接卷

搭建本地yum源

本地yum源，就意味着只有搭建该yum源的这台服务器能使用，其它的服务器都不能使用该yum源。搭建本地yum源的所有步骤如下：

#准备好一个centos 的镜像，我这里是CentOS-7-x86_64-DVD-1810.iso


# 在/local-yum目录创建挂载镜像的文件夹


# 将iso镜像挂载到/mnt/iso目录
mount -o loop CentOS-7-x86_64-DVD-1810.iso /local-yum


# 挂载成功后可以使用df -h命令查看
[root@localhost application]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   50G  1.9G   49G   4% /
devtmpfs                  63G     0   63G   0% /dev
tmpfs                     63G     0   63G   0% /dev/shm
tmpfs                     63G   11M   63G   1% /run
tmpfs                     63G     0   63G   0% /sys/fs/cgroup
/dev/sda2               1014M  138M  877M  14% /boot
/dev/sda1                200M   12M  189M   6% /boot/efi
/dev/mapper/centos-home  392G  9.0G  383G   3% /home
tmpfs                     13G     0   13G   0% /run/user/0
/dev/loop0               4.5G  4.5G     0 100% /local-yum




# 修改yum配置文件，把原先的配置先备份了
cd /etc/yum.repos.d
mkdir bak
mv *.repo ./bak

#新建local.repo
vim /etc/yum.repos.d/local.repo

[base]
name=CentOS
baseurl=file:///local-yum
enabled=1
gpgcheck=0



#清除下yum 原有的信息，载入新的缓存
yum clean all
yum makecache

这样，一个崭新的本地yum源就可以使用了。

搭建局域网yum源

除了可以搭建本地yum源外，我们还可以基于HTTP方式配置yum源，这样我们就可以配置一个局域网内都可以使用的yum源。

一般都是通过apache 来搭建HTTP的yum源，本次我们使用Nginx搭建

#官网下载nginx1.18.0
wget http://nginx.org/download/nginx-1.18.0.tar.gz

#安装依赖包，NGINX是C语言写的，pcre-devel支持正则表达式，openssl 开启加密
[root@proxy ~]# yum -y install gcc pcre-devel openssl-devel   


#创建NGINX用户，为了安全起见，不允许登录系统
[root@proxy ~]# useradd -s /sbin/nologin nginx  


#解压，安装，这里把nginx 部署在/home/application/nginx 目录下
[root@proxy ~]# mkdir /home/application/nginx 

[root@proxy ~]# tar  -xf   nginx-1.18.0.tar.gz
[root@proxy ~]# cd  nginx-1.18.0
[root@proxy nginx-1.18.0]# ./configure --prefix=/home/application/nginx --user=nginx --group=nginx --with-http_ssl_module

#编译安装
[root@proxy nginx-1.10.3]# make && make install


#创建yum仓库文件路径 /home/application/nginx-yum
[root@proxy ~]#mkdir -p /home/application/nginx-yum 

#编辑nginx 配置文件,定义端口为8899
[root@proxy ~]# vim /home/application/nginx/conf/nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       8899;
        server_name  localhost;
        location / {
            autoindex  on;
            root   /home/application/nginx-yum/;
        }
    }
}


#检查nginx 配置文件是否正确
[root@proxy ~]# /home/application/nginx/sbin/nginx -t
nginx: the configuration file /home/application/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /home/application/nginx/conf/nginx.conf test is successful

#将iso镜像文件挂载到临时目录下，再拷贝到yum仓库路径下 /home/application/nginx-yum
[root@proxy ~]# mkdir local-yum
[root@proxy ~]# mount -o loop CentOS-7-x86_64-DVD-1810.iso /local-yum
[root@proxy ~]# cd local-yum
[root@proxy ~]# cp -rp *  /home/application/nginx-yum/
[root@proxy ~]# ls -l /home/application/nginx-yum/

#确认配置没有问题后，启动nginx
[root@proxy ~]# /home/application/nginx/sbin/nginx


#查看端口
[root@localhost conf]# netstat -ntlup

#登陆浏览器访问查看yum仓库

#最后，我们开始配置yum的配置文件，在/etc/yum.repos.d新建一个名为nginx-yum.repo 的配置文件，内容如下：

vim /etc/yum.repos.d/nginx-yum.repo
[Nginx-yum]
name=nginx-yum
baseurl=http://10.114.0.15:8899
enabled=1
gpgcheck=0

#清除下yum 原有的信息，载入新的缓存

yum clean all
yum makecache

这样，局域网yum源就可以使用了

#安装一个软件试下效果
