nginx开启密码认证

Posted 2020-08-15

nginx可以为网站或者目录设置密码认证，密码认证必须是要加密的。使用apache的htpasswd来创建密码！

使用htpasswd创建密码文件

htpasswd -c   第一次创建时使用-c，如果已存在会清空文件内容
                -m  表示以md5格式加密存放

                -D   删除用户

1、测试有无htpasswd命令

[[email protected] conf]# htpasswd -bash: htpasswd: command not found

  如果没有此命令可以使用yum -y install httpd来实现

  使用示例：htpasswd -c -m /etc/httpd/conf/htpasswd 用户名，以此输入密码即可

  如不想安装httpd可以使用下面两种方法实现

  1.1、使用perl脚本实现，代码如下

[[email protected] conf]#vi auth_user.pl #! /usr/bin/perl -w   #filename: auth_ftp_user.pl   use strict;   #   print "#example: user:passwd\n";   while (<STDIN>) {       exit if ($_ =~/^\n/);       chomp;       (my $user, my $pass) = split /:/, $_, 2;       my $crypt = crypt $pass, ‘$1$‘ . gensalt(8);       print "$user:$crypt\n";   }   sub gensalt {       my $count = shift;       my @salt = (‘.‘, ‘/‘, 0 .. 9, ‘A‘ .. ‘Z‘, ‘a‘ .. ‘z‘);       my $s;       $s .= $salt[rand @salt] for (1 .. $count);       return $s;   }  脚本创建完成后为脚本添加可执行权限 chmod +x auth_user.pl 脚本使用方法 ./auth_user.pl user:password 将生成的用户名密码粘贴到/usr/local/nginx/conf/nginx_passwd文件中

     1.2、创建类htpasswd脚本文件

wget -c soft.vpser.net/lnmp/ext/htpasswd.sh 下载完成后执行htpasswd文件 [[email protected] passwd]# cat htpasswd.sh #!/bin/bash PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin export PATH echo "=====================================" echo "# A tool like htpasswd for Nginx    #" echo "#-----------------------------------#" echo "# Author:Licess http://www.lnmp.org #" echo "=====================================" #set UserName         username=""         read -p "Please input UserName:" username         if [ "$username" = "" ]; then                 echo "Error:UserName can‘t be NULL!"                 exit 1         fi         echo "==========================="         echo "UserName was: $username"         echo "===========================" #set password         unpassword=""         read -p "Please input the Password:" unpassword         if [ "$unpassword" = "" ]; then                 echo "Error:Password can‘t be NULL!"                 exit 1         fi         echo "==========================="         echo "Password was: $unpassword"         echo "===========================" password=$(perl -e ‘print crypt($ARGV[0], "pwdsalt")‘ $unpassword) #set htpasswd file         htfile=""         read -p "Please input Auth filename:" htfile         if [ "$htfile" = "" ]; then                 echo "Error:Auth filename can‘t be NULL!"                 exit 1         fi         echo "==========================="         echo "Auth File: /usr/local/nginx/conf/$htfile"         echo "==========================="         get_char()         {         SAVEDSTTY=`stty -g`         stty -echo         stty cbreak         dd if=/dev/tty bs=1 count=1 2> /dev/null         stty -raw         stty echo         stty $SAVEDSTTY         }         echo ""         echo "Press any key to Creat...or Press Ctrl+c to cancel"         char=`get_char` if [ ! -f /usr/local/nginx/conf/$htfile.conf ]; then   echo "Create Auth file......" cat >/usr/local/nginx/conf/$htfile.conf<<eof $username:$password eof echo "Create Auth file successful,auth file path:/usr/local/nginx/conf/$htfile.conf." else         echo "File already exists,please run this script again."         exit 1 按照提示输入用户名密码及认证文件名，脚本既会生成认证文件。

2、在nginx配置文件中添加认证配置

   2.1、如果是给网站添加认证，只需把认证语句添加到server段即可

server   {       listen 80;       server_name www.test.com;       root /home/src;       index index.html index.htm index.php;       auth_basic "input you user name and password";       auth_basic_user_file /usr/local/nginx/conf/vhost/nginx_passwd;

   2.2、如果是给网站目录添加认证，在一个单独的location中，并且在该location中嵌套一个解释php的location，否则php文件不会执行并且会被下载。auth_basic在嵌套的location之后。

server   {       listen 80;       server_name www.test.com;        root /home/src;           index index.html index.htm index.php;       location ~ ^/admin/.*       {       location ~ \.php$       {           fastcgi_pass 127.0.0.1:9000;           fastcgi_index index.php;           include fastcgi_params;       }       auth_basic "input you user name and password";        auth_basic_user_file /usr/local/nginx/conf/vhost/nginx_passwd;       }       location ~ .php$       {           fastcgi_pass 127.0.0.1:9000;           fastcgi_index index.php;           include fastcgi_params;       }

添加完成后重启nginx即可
