使用nginx搭建简易的文件共享服务器

前期准备

使用yum的方法安装nginx，提供以下脚本供安装使用。

#!/bin/bash
. /etc/os-release

#捕获ctrl+c信号
trap "exit" INT 

#日志处理
color(){
  if [[ "$1" == "error" ]]
  then

    printf "\e[1;31m[Error] $(date +"%F %T"): $2\n\e[0m"
  elif [[ "$1" == "info" ]]
  then
    printf "\e[1;32m[info] $(date +"%F %T"): $2\n\e[0m"
  elif [[ "$1" == "warning" ]]
  then
    printf "\e[1;33m[warning] $(date +"%F %T"): $2\n\e[0m"

  fi
}

#安装nginx，目前在rocky8，ubnutu20.4运行无问题，其他版本未试过
_install_nginx(){
  REPLY=y
  color warning "reinstall will uninstall and install again,deep think about...."
  [[ -f "/lib/systemd/system/nginx.service" ]] && read -p "your already installed nginx,do you want install again[y|n]?"
  case $REPLY in
    y|Y)
      if [[ "$ID" == "ubuntu" ]] 
      then
        color info "uninstall nginx"
        sudo apt autoremove nginx -y
        color info "install nginx"
        #ubuntu
        sudo apt update -y
        curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
            | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
        echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
        http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
            | sudo tee /etc/apt/sources.list.d/nginx.list
        sudo apt update
        sudo apt install nginx -y
        systemctl restart nginx
        systemctl status nginx
        curl -I  127.0.0.1:80|grep "HTTP/1.1 200 OK" &>/dev/null
        color info "nginx server is running ...."
      elif [[ "$ID" == "rocky" ]]
      then
        color info "uninstall nginx"
        yum install yum-utils expect -y
        yum autoremove nginx -y
        color info "install nginx"
        [ -f "/etc/yum.repos.d/nginx.repo" ] && mv /etc/yum.repos.d/nginx.repo /etc/yum.repos.d/nginx.repo.bak.$(date +%s) &>/dev/null
        cat >/etc/yum.repos.d/nginx.repo<<EOF

  echo "input error,exit after 2 second"
  sleep 2
  exit 1
esac
}

新建目录

mkdir -p /myrepo/epel   #路径可随意

关闭selinux

如果不关闭会出现403的报错，关闭完成后重启机器生效

sed '/^SELINUX=/ s/enforcing/disabled/' -i  /etc/selinux/config

临时关闭

[root@localhost yum.repos.d]# setenforce 0
[root@localhost yum.repos.d]# getenforce 
Permissive

​​将安装脚本保存为.sh文件，然后使用bash 脚本名.sh​​执行脚本修改nginx配置文件，添加如下配置

location /repo  {
           alias /myrepo/epel;
           autoindex on;
        }

重启nginx

systemctl restart  nginx

访问http://ip/repo,出现如下界面说明配置成功
