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/
- total 4669768

- #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
- Active Internet connections (only servers)
- Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
- tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 16129/sshd
- tcp 0 0 0.0.0.0:8899 0.0.0.0:* LISTEN 41103/nginx: master
- tcp6 0 0 :::22 :::* LISTEN 16129/sshd
- 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
