飘零的代码 piao2010 ’s blog

  之前接触的是FreeBSD，最近想学习一下Linux，朋友推荐centOS，于是就打算在服务器上装一个跑跑。

下载安装就不说了，都挺简单的。设置好网络，配置好SSH，基本上和BSD下一致。然后准备安装软件，yum命令听说特别好用，哈哈！首先设置一下，这里采用的是科大的 http://centos.ustc.edu.cn/

步骤一：

 cd /etc/yum.repos.d

mv CentOS-Base.repo  CentOS-Base.repo.save

wget http://centos.ustc.edu.cn/CentOS-Base.repo.5

mv CentOS-Base.repo.5 CentOS-Base.repo

步骤二：

rpm –import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

然后yum update一下。

接下来安装软件就爽了。yum install XXX

配置软件的过程和BSD下基本一致，但是yum命令比BSD的ports更快更简单。

官方的文件通俗易懂，相信有需要的朋友们一看就能明白。

0. Introduction, and some stuff you should know.
————————————————

0.3.7 (Beta). It has been a while I know. But this year has been a hell, last
year of uni, projects, thesis, …. it didn’t stop. Well that is behind us
now, the most important thing, is that I’m back working on the program again,
and intend to keep on doing it.

I hope you enjoy this beta version. Like always, I removed some bugs. There
is a new ‘logging’ feature. It is now possible to record traffic with
Sniffit and process it later! (it is completely different from the logging
done in the 0.3.6 version, that is known to some hardcore Sniffit users)
Please take a minute to skim through the text and read the passages marked
with a ‘*’, these are the new features.
(Please read BETA-TESTING)

I use the libpcap library developed at Berkeley Laboratory, for easy
porting (Read the licence).

客户端用密钥方式登陆到 FreeBSD SSH服务器

一、密匙认证原理简介
　　密匙认证需要依靠密匙，首先创建一对密匙（包括公匙和私匙,用公匙加密的数据只能用私匙解密），把公匙放到需要远程服务器上，私钥放在客户端。这样当登录远程服务器时，客户端软件就会向服务器发出认证请求；服务器收到请求之后，先在服务器的宿主目录下寻找你的公匙，然后检查该公匙是否是合法，如果合法就用公匙加密一随机数生成所谓 read more »

因为配置很简单，算是原创吧。o(∩_∩)o…

freebsd# whereis socks5
socks5: /usr/local/bin/socks5 /usr/local/man/man1/socks5.1.gz /usr/ports/net/socks5
freebsd# cd /usr/ports/net/socks5

然后make install

完成后/etc/rc.conf 增加一条：socks5_enable=”yes”

配置文件：/usr/local/etc/socks5.conf

#指定SOCKS v5绑定的ip地址和监听的端口。如果不指定绑定的IP将使用0.0.0.0
set SOCKS5_BINDINFC 0.0.0.0:1080
#忽略ident请求。当客户机没有运行identd时，使用SOCKS5_NOIDENT将降低超时值
set SOCKS5_NOIDENT
#指定连接停顿最长时间。超过最大值后， read more »

文章是参考别人的，本人是在原先lighttpd+fastcgi(php)+mysql环境下直接安装nginx，然后修改相关配置文件/usr/local/etc/nginx/nginx.conf

location / {

root    /usr/local/www/nginx;

index    index.php index.html index.htm;

}

location ~ \.php$ {

fastcgi_pass    127.0.0.1:9000;

fastcgi_index   index.php;

fastcgi_param     SCRIPT_FILENAME     /usr/local/www/nginx$fastcgi_script.name;#PHP文件所在目录

include      fastcgi_params;

}

本来是很简单的一个过程，启动的时候出现了问题，unknown “fastcgi_script” variable

然后只能把

fastcgi_param     SCRIPT_FILENAME     /usr/local/www/nginx$fastcgi_script.name;

修改成

fastcgi_param     SCRIPT_FILENAME     /usr/local/www/nginx;

启动时候是不报错了，但是访问PHP文件出错nginx No input file specified

结果在网上找了一堆资料搞了半天，很多提到php.ini里面的相关设置。 read more »
