搭建本地的yum仓库-较简单

1.创建目录安装软件程序

1.在/root路径下创建123.sh文件，把此文件复制到123.sh里，  sh 123.sh
2.首选安装nginx，作为web展示

3.强力清除老版本残留
rpm -e nginx --nodeps
rm -rf  /etc/nginx

4.开始安装
yum install -y nginx

2.配置文件的编辑

cat > /etc/nginx/nginx.conf << EOF
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {worker_connections 1024;}
http {log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;
    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    server{
    listen              80;
    root                /var/ftp/pub/;
    autoindex on;}      }
EOF

#安装vsftpd
yum install  vsftpd -y

#启动自启nginx,ftp
systemctl start nginx
systemctl enable nginx
systemctl start vsftpd
systemctl enable vsftpd

createrepo /var/ftp/pub/centos/7/centosplus/x86_64/

EOF

3.最后一步，执行脚本同步

sh /var/ftp/pub/centos7-rsync.sh

4.做一个定时更新yum源的任务（可做可不做）

echo "#每天4点更新yum源
00 04 * * *  /usr/bin/sh    /var/ftp/pub/centos7-rsync.sh  &> /dev/null" >> /var/spool/cron/root
