安装 Suse 10.3 及 Linux 笔记
This is a memo of setting up Suse 10.3 on Mon Mar 17, 5:18 PM
Download Open Suse: http://en.opensuse.org and see http://en.opensuse.org/Download_Help
Summary - These tools were configured to use:
Apache 2.2 web server
Bison 2.3
Flex 2.5.33
Ftp server
Gcc 4.2.1 (C/C++)
Java 1.5.0
Mono (C# cross compiler)
MySQL (Ver 14.12 Distrib 5.0.45, for suse-linux-gnu (i686) using readline 5.2)
Perl (v5.8.8 built for i586-linux-thread-multi)
Php (PHP 5.2.4 with Suhosin-Patch 0.9.6.2 (cli) (built: Sep 23 2007 14:12:53))
phpBB 3.0.1
Python 2.5.1
SSH server
Demos
cgi-bin/hi.cgi
(cgi written in Perl)
cgi-bin/hi.pl
(cgi written in Perl)
cgi-bin/chi.cgi
(cgi written in C)
php/index.php
(PHP)
cgi-python/hi.py?user_name=me
(Python as cgi, use mod_python.cgihandler as handler)
python/index.py (with a function hello(req, who))
(Python, use mod_python.publisher as handler, the better way)
Perl using MySQL database
Apache
www root is /srv/www/htdocs/
config files are in /etc/apache2/
See apache.txt
for configuration change.
Crontab
crontab.txt
MySQL
Install notes
See Setup guide
The Perl-DBD-MySQL module was missing. So download and install using YaST.
DBD::mysql module note
DBD modules download
Database auto-backup using crontab
Menhir
Menhir install records
OCaml
ocaml.txt
phpBB
phpBB website
To install is very easy, follow the instruction guide
. Note that the database needs to be created manually.
(For MySQL, in MySQL shell, type "create DATABASE [database_name]")
Python
Mod_Python - Integrating Python with Apache
Ruby on Rails
RailsOnSUSE on SUSE 10.0
General note
Notes on install CPAN modules
Installing Perl Modules
In Suse, can use YaST --> Software Management to install new package.

Linux 内核启动分析
1. 内核启动地址
1.1. 名词解释
ZTEXTADDR
解压代码运行的开始地址。没有物理地址和虚拟地址之分，因为此时MMU处于关闭状态。这个地址不一定时RAM的地址，可以是支持读写寻址的flash等存储中介。

一、准备工作
首先说明，下面带#号的行都是要输入的命令行，且本文提到的所有命令行都在终端里输入。启动Linux系统，并用根用户登录，进入终端模式下。
1、查看Linux内核版本
# uname -a
如果屏幕显示的是2.6.x，说明你的已经是2.6的内核，也用不着看下文了，该干什么干什么去吧！~~~如果显示的是2.4.x，那恭喜你，闯关 ......

几乎每个接触类 Unix 操作系统的工程师都知道如何查看系统负载。但这东西的工作机理到底是怎样的，可能没有多少能说清楚。对比了一些相关信息，加上自己的理解，做一下笔记。

并发与竞态
解决竞态问题的途径是保证对共享资源的互斥访问。
访问共享资源的代码区域称为临界区，临界区需要以某种互斥机制加以保护。中断屏蔽、原子操作、自旋锁和信号量等是Linux设备驱动中可采用的互斥途径。
中断屏蔽
中断屏蔽将使得中断与进程之间的并发不再发生，而且，由于Linux内核的进程调度等操作都依赖 ......
