Cenos7搭建yum源仓库和配置epel源

1、配置国内优秀的yum源仓库和epel源

/etc/yum.conf #为所有仓库提供公共配置

/etc/yum.repos.d/*.repo #为每个仓库提供配置文件

[root@y_zilong yum.repos.d]# cat tx.repo 
[tx]
name=tx     #自定义源名字
baseurl=https://mirrors.cloud.tencent.com/centos/7/os/x86_64/ 
#访问路径指定到repodate数据文件的上级目录
enabled=1    
#是否启用软件仓库(1启动,0不启用)
gpgcheck=1     
#安装包前要做包的合法和完整性效验
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
#指定公钥文件存放位置

[epel]
name=epel
baseurl=https://mirrors.cloud.tencent.com/epel/7/x86_64/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[root@y_zilong yum.repos.d]# yum clean all  #清除缓存

epel                                                                            | 4.7 kB  00:00:00     
tx                                                                              | 3.6 kB  00:00:00

2、为CentOS7用系统安装光盘作的本地网络yum仓库

本地yum源是利用光盘镜像作为本地yum源

1.安装http服务, 关闭防火墙,测试服务是否可用, 在本地浏览器输入本机ip地址

[root@y_zilong ~]# systemctl stop firewalld   #关闭防火墙
[root@y_zilong ~]# systemctl enable firewalld
[root@y_zilong ~]# yum install -y httpd        #安装httpd
[root@y_zilong ~]# systemctl enable --now httpd

2.创建网页页面

[root@y_zilong ~]# cd /var/www/html/
[root@y_zilong html]# mkdir -p centos/7/os

3.安装autofs服务,在客户端上面持续检测某个指定的目录,并预先设置当使用到该目录的某个子目录时,将会取得来自服务器端的NFS文件系统资源,并进行自动挂载的操作

[root@y_zilong ~]# yum install -y autofs
[root@y_zilong ~]# systemctl enable --now autofs

4. 挂载光盘到网页/var/www/html/centos/7/os目录

[root@y_zilong ~]# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0   20G  0 disk 
├─sda1   8:1    0  300M  0 part /boot
├─sda2   8:2    0    2G  0 part [SWAP]
└─sda3   8:3    0 17.7G  0 part /
sr0     11:0    1  4.1G  0 rom  
sr1     11:1    1  4.4G  0 rom  /var/www/html/centos/7/os
[root@y_zilong ~]# cd /var/www/html
[root@y_zilong html]# mount /dev/sr1 centos/7/os

5.使用本地网络yum仓库的服务器配置本地源

[root@y_zilong yum.repos.d]# cat base.repo 
[base]
name=Centos
baseurl=http://10.0.0.102/centos/7/os/
enabled=1
gpgcheck=0
[root@y_zilong yum.repos.d]# 
[root@y_zilong yum.repos.d]# yum repolist
Loaded plugins: fastestmirror, langpacks
base                                                                            | 3.6 kB  00:00:00     
(1/2): base/group_gz                                                            | 165 kB  00:00:00     
(2/2): base/primary_db                                                          | 3.2 MB  00:00:00     
Determining fastest mirrors
repo id                                          repo name                                       status
base                                             Centos                                          4,067
repolist: 4,067
