阅读更多关于在Debian 7上配置Nginx + php-FPM + apc + MariaDB(翻译)

配置 Debian 是作为Linux Web服务器，是一个非常不错的选择，她是当前仅次于Centos的最受欢迎的服务器操作系统。我非常喜爱在系统上使用apt/dpkg/gedbi命令去安装和更新软件包，这非常方便。安装一个功能完善的php 服务器环境，你需要安装一整套的配套软件，包括一个网页服务器，一个数据库。在本篇文章中，我们将安装配置nginx, php, php-fpm, apc 和 MariaDB。 Nginx是一个新潮的网页服务器，它被设计成为能承受巨大网络流量而且使用最少的内存和CPU占用量。在Nginx出现之前，独步武林的网页服务器是Apache。然而，随着互联网的越来越流行，就需要一个更快速，效率更高的网页服务器。 Nginx vs Apache Apache 的设计是模块化的，具拥有很多的功能，但是大部的功能在常规的网站中都是用不上的，它的设计可能是为了迎合所有人的需求，但是最后的结果是制造了一个重量级的且包含大部分不常用功能的网页服务器。 Nginx 在另一方面是非常时髦和极速的网页服务器，主要集中在速度、扩展性及性能上。关于它的强大的技术已经超出了本文的范围。我们可能在后面作一些介绍。能告诉你的信息是，这个网站就是运行在Nginx上。现在，抛开那些更深的讨论，让我们开始吧！在Debian下安装Nginx Debian的官方包中已经有了Nginx包

一、系统环境本文服务器系统环境是：CentOS5.5，备份机系统环境是：Debian 2.6.32-5-amd64。二、rsync的下载与安装目前大部分Unix/Linux默认即安装了rsync。三、服务端rsync的配置 rsync服务器的配置文件，默认是没有的，需要手工创建。创建三个文件，具体如下。 /etc/rsyncd.conf #rsync服务器的主配置文件 /etc/rsyncd.secrets #rysnc用户密码文件 /etc/rsyncd.motd #定义rysnc服务器信息，此步骤对备份无任何影响，可以忽略。 1、主配置文件rsyncd.conf rsyncd.conf是rsync服务器主配置文件，比如我们要备份服务器上的/home/share。 vi /etc/rsyncd.conf #全局配置 strictmodes=yes #是否检查口令文件的权限 port=873 # TCP 873 uid=nobody #允许组 gid=nobody #允许用户 max connections=5 #最大连接数，0是无限制 motd file = /etc/rsyncd.motd log file = /var/log/rsync.log transfer logging = yes log format = %t %a %m %f %b timeout

阅读更多关于 How do I package Mono applications for Debian/Ubuntu

问题 Are there any guidelines or tools for packaging Mono applications for Debian/Ubuntu? Like where to put Assemblies that ship with the application etc. 回答1: Mono has some general guidelines about packaging, but these are not specific to Debian/Ubuntu who may do things differently: http://www.mono-project.com/Guidelines:Application_Deployment 回答2: There's, of course, the Debian CLI Policy. It's a dry read, but will probably clarify some details as to where are some files expected to be deployed.

问题 For a week now I've been trying to get my mono configuration running with apache. I must have tried virtually anything, shamefully I notice no changes, the problem remains the same. When I try to connect to the server I get a 503 error: Service Temporarily Unavailable When I take a look at the errror log it appears empty and I'm quite sure it's not an permission problem.

问题 I was writing an if statement which checked if a file is readable and exists by doing the following: if [[ -r "$upFN" && -f "$upFN" ]]; then .... fi Then I thought, surly you can make this smaller, something maybe like this: if [[ -r -f "$upFN" ]]; then .... fi But this doesn't work, it returns errors: ./ftp.sh: line 72: syntax error in conditional expression ./ftp.sh: line 72: syntax error near `"$upFN"' ./ftp.sh: line 72: `if [[ -r -f "$upFN" ]]; then' 回答1: AFAICT, there is no way to
