CentOS 7 rsync+nginx实现公网yum源

1、实验描述

2、实验环境

3、实验工具

4、实验步骤

4.1 安装nginx服务

1. 配置官方源

echo '[nginx]
name=Nginx repo by MineGi
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1' >/etc/yum.repos.d/nginx.repo

cat /etc/yum.repos.d/nginx.repo

2. 安装与配置

yum install -y nginx &>/dev/null
echo $?

IP=$(ip a|awk -F '[ /]+' '$NF~/eth0/ {print $3}')
cat >/etc/nginx/conf.d/yum.conf <<EOF
server {
    listen       80;
    listen      [::]:80;
    server_name  $IP;
    location / {
        root   /usr/share/nginx/html;
        autoindex on;
    }
}
EOF

cat /etc/nginx/conf.d/yum.conf

mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default

3. 启动自启动

nginx -t

systemctl enable nginx

systemctl start nginx

netstat -lntup|grep -c nginx

4.2 同步公网yum源

1. 创建排除文件

cat >/root/.rsync_exclude.txt <<EOF
centosplus/
cloud/
contrib/
cr/
fasttrack/
isos/
sclo/
storage/
virt/
i386/
debug/
drpms/
EOF

cat /root/.rsync_exclude.txt

cat >/root/.rsync_exclude2.txt <<EOF
atomic/
centosplus/
cloud/
configmanagement/
cr/
dotnet/
fasttrack/
isos/
nfv/
opstools/
paas/
rt/
sclo/
storage/
virt/
debug/
drpms/
EOF

cat /root/.rsync_exclude2.txt 

2. 手动执行

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude2.txt \
  rsync://rsync.mirrors.ustc.edu.cn/centos/7.6.1810 /usr/share/nginx/html/centos

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt \
  rsync://rsync.mirrors.ustc.edu.cn/centos/6.10 /usr/share/nginx/html/centos

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt \
  rsync://rsync.mirrors.ustc.edu.cn/epel/7/x86_64 /usr/share/nginx/html/epel/7/

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt \
  rsync://rsync.mirrors.ustc.edu.cn/epel/6/x86_64 /usr/share/nginx/html/epel/6/

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude2.txt \
  rsync://rsync.mirrors.ustc.edu.cn/centos/7 /usr/share/nginx/html/centos

/usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt \
  rsync://rsync.mirrors.ustc.edu.cn/centos/6 /usr/share/nginx/html/centos

3. 定时任务

crontab -e

30 21 * * * /usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude2.txt rsync://rsync.mirrors.ustc.edu.cn/centos/7.6.1810 /usr/share/nginx/html/centos &>/dev/null

00 22 * * * /usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt rsync://rsync.mirrors.ustc.edu.cn/centos/6.10 /usr/share/nginx/html/centos &>/dev/null

00 21 * * * /usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt rsync://rsync.mirrors.ustc.edu.cn/epel/7/x86_64 /usr/share/nginx/html/epel/7/ &>/dev/null

30 20 * * * /usr/bin/rsync -zaP --exclude-from /root/.rsync_exclude.txt rsync://rsync.mirrors.ustc.edu.cn/epel/6/x86_64 /usr/share/nginx/html/epel/6/ &>/dev/null

crontab -l

4. 验证结果

1. 文件

rm -f /usr/share/nginx/html/*.html

cd /usr/share/nginx/html/ && ls

du -smh centos epel

cd centos && ll

2. 结果

curl -s -o /etc/yum.repos.d/CentOS-Base.repo \
  http://mirrors.aliyun.com/repo/Centos-7.repo

curl -s -o /etc/yum.repos.d/epel.repo \
  http://mirrors.aliyun.com/repo/epel-7.repo

echo '10.0.0.10  mirrors.aliyun.com' >>/etc/hosts

tail -1 /etc/hosts

rpm -e --nodeps bc

rpm -qa bc

yum install -y bc &>/dev/null

rpm -qa bc

4.3 开启下游同步

cat >/etc/rsyncd.conf <<EOF
#rsync server
uid = nginx
gid = nginx
use chroot = no
max connections = 2000
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = true
list = true
hosts allow = 0.0.0.0/0
[centos]
path = /usr/share/nginx/html/centos
[epel]
path = /usr/share/nginx/html/epel
EOF

cat /etc/rsyncd.conf
