yum内网私有仓库

为什么需要私有YUM仓库

1.下载速度慢
2.需要有外网
3.有些Base源和epel源软件没有，需要单独创建下载源

需要的软件：

createrepo 
nginx

操作步骤：

1.配置nginx索引模块

[root@web01 ~]# cat /etc/nginx/conf.d/index.conf 
server {
    listen       80;
    server_name  yum.mysun.com;
    location / {
        autoindex on;
        autoindex_exact_size off;
        autoindex_localtime on;
        autoindex_format html;
        charset utf-8,gbk;
        root   /data/yum;
        index  index.html index.htm;
    }
}

2.安装createrepo

yum install createrepo -y

3.准备软件仓库目录并下载需要的软件

yum install --downloadonly --downloaddir=/data/yum nginx screen vim tree -y

4.生成yum元数据

createrepo /data/yum 

5.客户端生成本地源

[root@web02 ~]# cat /etc/yum.repos.d/local.repo 
[local]
name=local
enable=1
gpgcheck=0
baseurl=http://10.0.0.7

6.客户端测试安装

yum makecache
yum search nginx 
yum install nginx

更新软件包的操作步骤：

第一种方法：真实下载

1.打开yum缓存

[root@web01 /data/yum]# grep "keepcache" /etc/yum.conf 
keepcache=1

2.清空原来的缓存

yum clean all 

3.下载软件php

yum remove php-mysql-5.4 php php-fpm php-common
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache -y

4.移动已经缓存下来的rpm包到yum仓库目录

find /var/cache/yum/ -type f -name "*.rpm"|xargs mv -t /data/yum/

5.生成新的yum元数据

createrepo --update /data/yum/

第二种方法：只下载不安装

yum install --downloadonly --downloaddir=/data/yum php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache
