利用yum命令同步yum源到本地
默认centos的yum源是国外的源,我们可以把自己的源修改成阿里云,清华大学,163的源
先来备份已经有的yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
下载阿里云的base源到本地
Centos6的
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo
Centos7的
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
Centos8的
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
下载阿里云的epel源到本地
备份已有的源
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup
下载新repo 到/etc/yum.repos.d/
Centos-8的
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
Centos-7的
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
Centos-6的
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
选择一种就可以,可以直接选择阿里云的镜像源
如果用清华大学的镜像源不需要备份
修改地址:
https://mirrors.tuna.tsinghua.edu.cn/help/centos/
安装需要同步的软件包和创建repo数据库的命令
yum install yum-utils createrepo -y
创建同步下来存放rpm包的目录
mkdir -pv /var/ftp/pub/centos/{6..7}
mkdir -pv /var/ftp/pub/epel/{6..7}
先来同步base源,同步base源以后再去同步epel源
Centos-7同步base源
reposync -r base -r updates -p /var/ftp/pub/centos/7/
Centos-7同步epel源
reposync -r epel -p /var/ftp/pub/centos/7/
创建yum所引数据库
createrepo /var/ftp/pub/centos/7/
createrepo /var/ftp/pub/epel/7/
以上如果报错,执行以下,不报错千万不要去执行
createrepo /var/ftp/pub/centos/7/base/
createrepo /var/ftp/pub/centos/7/updates
安装nginx,脚本运行,让yum源,以web形式展示
编译一个脚本文件
vim install_nginx.sh
写入以下内容
#!/bin/bash
#nginx-install
NG_DIR="/usr/local/nginx"
NG_CS="--user=www --group=www --with-http_stub_status_module --with-http_ssl_module"
yum install wget gcc pcre pcre-devel openssl-devel openssl gzip createrepo make cmake zlib-devel tar lrzsz -y
wget -c http://nginx.org/download/nginx-1.18.0.tar.gz
tar -xzf nginx-1.18.0.tar.gz
cd nginx-1.18.0
useradd www -s /sbin/nologin
./configure --prefix=$NG_DIR $NG_CS
make
make install
echo $?

#设置为nginx开机自启动,并设置为开机自启动
systemctl daemon-reload
systemctl start nginx.service
systemctl enable nginx.service
ss -ntl
#安装vsftpd
yum install vsftpd -y
systemctl enable vsftpd
systemctl start vsftpd
执行脚本,等待几分钟就行了,然后用浏览器访问你的服务器的IP地址
sh install_nginx.sh
