自己搭建yum仓库

1.关闭防火墙和SELinux

# systemctl stop firewalld

# systemctl disable firewalld

# vim /etc/selinux/config

SELINUX=disabled

2.安装yum-utils createrepo

# yum install yum-utils createrepo

3.同步包，这里选择阿里源

/etc/yum.repos.d/CentOS-Base.repo默认的就是腾讯的yum源

# wget http://mirrors.aliyun.com/repo/Centos-7.repo

# cp Centos-7.repo /etc/yum.repo.d/CentOS-Base.repo

# reposync –p /data/yum/

# ll /data/yum/

total 24

drwxr-xr-x 3 root root 4096 Aug 28 08:53 base

drwxr-xr-x 3 root root 4096 Aug 27 23:46 epel

drwxr-xr-x 3 root root 4096 Aug 27 23:58 extras

drwxr-xr-x 3 root root 4096 Aug 28 00:02 nginx

drwxr-xr-x 3 root root 4096 Aug 28 00:38 updates

创建yum列表，完成后会发现多了一个这个目录：

# createrepo -p /data/yum

# ll /data/yum/

drwxr-xr-x 2 root root 4096 Aug 28 09:03 repodata

4.安装Nginx

# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

# yum install -y nginx

需要添加几行配置：

# vim /etc/nginx/nginx.conf

user root;

http {

...

autoindex on;

autoindex_exact_size off;

autoindex_localtime on;

...

}

4)在Nginx里面创建一个软连接目录指向/data/yum

# cd /usr/share/nginx/html

# ln -s /data/yum CentOS-yum/version_7/64bit

名字可以自己定义，还可以分不同的版本，这里就用centos7的好了

5)启动nginx服务

systemctl start nginx

6)编辑repo文件

需要安装一个软件，可以控制yum源先后使用查找

# yum install -y yum-plugin-priorities

# vim /etc/yum.repos.d/CentOS-Base.repo

[mylocal]

name=source_from_localserver

baseurl=http://132.232.82.148/yum

gpgcheck=0

enable=1

priority=1

7）刷新yum缓存并重建

# yum clean all

# yum makecache

Loaded plugins: fastestmirror, langpacks, priorities

epel | 3.2 kB 00:00:00

mylocal | 2.9 kB 00:00:00

nginx | 2.9 kB 00:00:00

(1/2): mylocal/other_db | 6.1 MB 00:01:49

(2/2): mylocal/filelists_db | 21 MB 00:03:55

Loading mirror speeds from cached hostfile

Metadata Cache Created

可以看到本地的yum缓存已经出来了

# yum repolist

8）测试一下：

# yum install -y tree

Dependencies Resolved

================================================================================================================================

Package Arch Version Repository Size

================================================================================================================================

Installing:

tree x86_64 1.6.0-10.el7 mylocal 46 k

Transaction Summary

================================================================================================================================

Install 1 Package

Repository已经显示的是mylocal

9）自动更新

# crontab -l

0 2 * * 6 # reposync -np /data/yum >>/dev/null 2>&1

设置一个自动命令，在每周6凌晨2点的时候进行更新，-np表示只更新新的rpm包
