安裝系統監看

1. 安裝snmpd:
   $ apt-get install snmpd
   接著編輯設定檔
   $ vim /etc/snmp/snmpd.conf
   大約第60行的地方, 改成像下面這個樣子:
   # sec.name source community
#com2sec paranoid default public
com2sec readonly default public
#com2sec readwrite default private
   接著在大約第109行的地方, 編輯syslocation和syscontact, syslocation後面接主機的名稱, syscontact後面則接管理者的聯絡資料, 這兩樣設定只作識別用途, 可以隨意設定, 存檔後執行
   $ /etc/init.d/snmpd restart
   讓設定檔生效.






2. 安裝cacti和rrdtool:
   $ apt-get install cacti

安裝webmin 管理介面

Installing Webmin in Ubuntu

You can use the above procedure but if you want to install latest version you can download from webmin site download section

Prerequisites

Perl 5 interpreter and libnet-ssleay-perl

#apt-get install perl5 libnet-ssleay-perl

Now you need to download the latest webmin from the above downloadlink

Download ‘webmin-1.290.tar.gz’ (at the time of writing) to some location in your machine ex:- /usr/local/src

#wget http://prdownloads.sourceforge.net/webadmin/webmin-1.290.tar.gz

#cd /usr/local/src

#tar xzvf webmin-1.290.tar.gz

#cd webmin-1.290

自動重開機

Add the following to /etc/sysctl.conf:

kernel.panic = 20

安裝 Ruby on Rails

注意應用程式目錄的檔案屬性(包括母目錄，否則會有 You don't have permission to access / on this server 的錯誤。

ex:
sudo rails test

sudo chown -R www-data:www-data test

應用程式放上去後，試試 rake db:migrate 檢查權限，如果這裡有問題，會發現 mysql 的權限可能有誤。

特定版本的 rails 設定
安裝:

最新版本:
sudo gem install rails

sudo gem install rails --version 2.0.2

將特定版本的 rails 放在該 ap 下
rake rails:freeze:edge TAG=rel_2-0-2

ps. 需要安裝 svn
sudo apt-get install subversion

rake rails:unfreeze


目前直接安裝 2.1
會出現 javascripts 及stylesheets 兩個目錄的檔案無法讀取。結果網站可以運作(特別的是 ajax 可以)，但是會以赤裸的 html 出現。解決方法：刪除 public 目錄裡的 .htaccess  即可。

ImageMagick Support

vi /etc/apache2/httpd.conf

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-1.0.5/ext/apache2/mod_passenger.so
RailsSpawnServer /usr/lib/ruby/gems/1.8/gems/passenger-1.0.5/bin/passenger-spawn-server
RailsRuby /usr/bin/ruby1.8

<VirtualHost *>
        ServerName xuelele.com.tw
        DocumentRoot /home/[user]/www/[ap]/public

其他:
磁碟管理工具
sudo apt-get install gparted

sudo apt-get install mysql-server
sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install php5-mysql
sudo apt-get install phpmyadmin

sudo gem update --system
Which introduced this error:
/usr/bin/gem:23: uninitialized constant Gem::GemRunner(NameError)
whenever I tried to run rubygems. On the rails forum, I found a fix for it!
Simply add the line to the file /usr/bin/gem (may be different on a mac)
require 'rubygems/gem_runner'
after
require 'rubygems'
