一、yum源构建（base源、updates源、epel源）

1. 找一台能连互联网的centos服务器，虚拟机也行。

2. 备份已有yum repo文件

cd /etc/yum.repo.d
mkdir bak
mv *.repo bak

3. 导入华为云yum repo

#导入华为yum源配置
cat > /etc/yum.repos.d/CentOS-Base.repo <<EOF
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.
You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

4. 安装yum源同步工具

yum -y install yum-utils createrepo

5. 同步yum源到本地

#yum源同步 ${downloadPath} 下载路径
reposync -r base -r updates -r epel -d -n -m -g -p ${downloadPath}

6. 创建repodata索引

createrepo -g
${downloadPath}/epel/comps.xml ${downloadPath}/epel/
createrepo -g
${downloadPath}/base/comps.xml ${downloadPath}/base/
createrepo ${downloadPath}/updates/

7. 打包离线源

tar -zcvf base.tar.gz ${downloadPath}/base/
tar -zcvf updates.tar.gz ${downloadPath}/updates/
tar -zcvf epel.tar.gz ${downloadPath}/epel/

二、yum源使用

1. 上传tar包到内网服务器

2. 解压文件

#创建解压路径
mkdir -p /var/www/html/centos7/
#解压 ${uploadPath}上传路径
tar -zxvf ${uploadPath}/base.tar.gz -C /var/www/html/centos7/
tar -zxvf ${uploadPath}/updates.tar.gz -C /var/www/html/centos7/
tar -zxvf ${uploadPath}/epel.tar.gz -C /var/www/html/centos7/

3. 备份已有repo

cd /etc/yum.repo.d
mkdir bak
mv *.repo bak

4. 配置本地源

#配置本地源
cat > /etc/yum.repo.d/local.repo <<EOF
[base]
name=CentOS-7-base
baseurl=file:///var/www/html/centos7/base
gpgcheck=0
enabled=1
priority=1
EOF
#本地源生效
yum clean all
yum makecache

5. 安装httpd服务

#从本地yum源安装
yum -y httpd
​#启动httpd服务
systemctl start httpd
#开机自启httpd服务
systemctl enable httpd

6. 配置内网源

#删除本地源配置
rm -rf /etc/yum.repos.d/local.repo
#配置内网源
#${localIP} 本地ip地址
cat > /etc/yum.repos.d/intranet_os.repo <<EOF
[base]
name=CentOS-7-base
baseurl=http://${localIP}/centos7/base/
gpgcheck=0
enabled=1
priority=1
[updates]
name=CentOS-7-updates
baseurl=http://${localIP}/centos7/updates/
gpgcheck=0
enabled=1
priority=1
[epel]
name=CentOS-7-epel
baseurl=http://${localIP}/centos7/epel/
gpgcheck=0
enabled=1
priority=1
EOF
#内网源生效
yum clean all
yum makecache
