Pradeep Gupta's questions

我正在使用 ruby​​ 脚本在我的 ubuntu 机器上安装tightvnc 服务器，我的脚本包含以下内容：

#!/usr/bin/ruby env    
`sudo apt-get --force-yes -y install tightvncserver`
`printf "%s\n%s\n" "demo123" "demo123" | vncserver :1`

我使用 printf 方式，因为 vncserver 在终端上要求输入密码，但是这种方式失败了，他们有没有更好的方法来解决这个问题？

我想使用 ruby​​ 脚本提供密码，这样终端就不会提示并要求用户提供密码。希望这清楚

我正在做 Ubuntu Server (Saucy) 13.10 的全自动安装，还想包含自定义的附加软件，preseed.cfg 的格式是：

d-i finish-install/reboot_in_progress note

我尝试通过在 %post 末尾写入自定义软件 juju、openstack 来包含它们，通过这种方式：

%post
juju
git
openstack
ruby

但是我遇到了解析错误，现在我尝试将这些软件包含在 pkgsel/include 中，但又遇到了错误，有什么办法可以解决这个问题吗？

我正在使用基于 Debian 的主机并使用 Nginx 和 PHP-FPM，我想在 nginx 中启用用户目录，并且还希望通过基本身份验证来支持多用户。这意味着当 Alex 打开 www.example.com/rutorrent；这将提示输入登录名和密码并在身份验证后，这应该指向他自己的位于 /home/alex/www/rutorrent 的 php 脚本版本以及 Bob 何时打开 www.example.com/rutorrent；这将提示登录和密码和身份验证后这应该指向他位于 /home/bob/www/rutorrent 的 php 脚本。

我已经尝试过位于此处的官方文档： http ://wiki.nginx.org/UserDir

但我不确定如何将它们配置到默认文件中，以便我可以获得所需的功能，我的 nginx 的默认配置文件在这里：

server {
    server_name localhost;

    location / {
          try_files $uri $uri/ /index.html;
    }

    location /doc/ {
           alias /usr/share/doc/;
           autoindex on;
           allow 127.0.0.1;
           allow ::1;
           deny all;
     }

     index index.php index.html index.htm;
     location ~ ^/~([^/]*)(.*)\.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            auth_basic "Restricted";
            auth_basic_user_file /etc/nginx/sites-available/.htpasswd;
            fastcgi_param SCRIPT_FILENAME /home/$1/www$2.php;
            include fastcgi_params;

     }

     location ~ ^/~([^/]*)(.*) {
            autoindex on;
            alias /home/$1/www$2;
            auth_basic "Restricted";
            auth_basic_user_file /etc/nginx/sites-available/.htpasswd;
     }

      location /RPC2 {
            include scgi_params;
            scgi_pass localhost:5000;
     }


}

有没有办法得到这个？

我使用 Debian 7 64 作为主机，并安装了支持 mysql 的 Lighttpd 和 PHP-FPM，全新安装 lighttpd 和 PHP-FPM 后，我尝试启用用户目录并运行以下命令：

[email protected]# lighty-enable-mod userdir

运行上面的命令后我得到了 Ok messege，但是当我运行下面的命令重新启动 lig​​httpd 时，我得到以下输出：

[email protected]# /etc/init.d/lighttpd force-reload
[FAIL] Reloading web server configuration: lighttpd failed!

我想打开 /home/user/www/project_name; 当有人打开我的网站时；像这样：www.mysite.com/project_name，所以我在 /etc/lighttpd/conf-available/10-userdir.conf 上做了以下更改

## The userdir module provides a simple way to link user-based directories into
## the global namespace of the webserver.
##
# /usr/share/doc/lighttpd/userdir.txt

server.modules      += ( "mod_userdir" )

## the subdirectory of a user's home dir which should be accessible
## under http://$host/~$user
userdir.path         = "/www/project_name/public_html"

## The users whose home directories should not be accessible
userdir.exclude-user = ( "root", "postmaster" )

以下是 /var/log/lighttpd/error.log 文件的输出。

我无法解决问题并寻找解决方案。

当我尝试编写以下命令时

我收到以下错误：

以下是调试：
