CentOS 5.6 快速搭建LAMP

在虛擬機器下安裝了個CentOS，5.6版本的。利用NAT模式與宿主pc共用上網！   
當然可以採用編譯源碼的方式搭建lamp。這裡只是介紹快速搭建php開發架構的方法。其實也沒什麼，主要是是是使用linux的yum來線上安裝。如果上不了網請尋找編譯源碼搭建lamp的文章。網上N多的哈^_^
   1.安裝mysql資料庫
     命令列下：yum -y install mysql mysql-server  
     Setting up Install Process
     Setting up repositories... ....
     ....................................................
     Installed: mysql-server.i386 0:4.1.20-1.RHEL4.1
     Dependency Installed: mysql.i386 0:4.1.20-1.RHEL4.1 perl-DBD-MySQL.i386 0:2.9004-3.1 perl-DBI.i386 0:1.40-8
     Complete!
    安裝完畢，配置mysql：
   命令列下：vi /etc/my.cnf        提示:紅色字為添加的行，主要是設定資料庫預設的字元集為utf8
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
default-character-set = utf8
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0
[mysql]
default-character-set = utf8
 儲存退出後，設定mysql服務隨系統自啟動，
命令列下：chkconfig mysqld on
       可以通過chkconfig --list mysqld 查看設定狀態，顯示 mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off，2~5顯示On就可以了。
 
  啟動mysql服務, /etc/rc.d.init.d/mysqld start
      Initializing MySQL database:　　　　　　　　 [ OK ]
      Starting MySQL: 　　　　　　　　　　　　　[ OK ]
可以登入mysql進行測試：mysql -u -root                     *(預設root的密碼是空的)
出現提示符“mysql〉”後，設定root的密碼。
以下動作出於安全考慮：
命令列下：mysql> use  mysql;
                    mysql> set password for root@localhost = password('你的密碼');
                    mysql> set password for root@localhost.localdomain=password('你的密碼');
刪除匿名使用者: mysql> delete from user where user='';   
刪除測試資料庫: mysql> drop database test;
至此，mysql資料安裝完成，可以用sql操作mysql測試。
2.安裝apache
命令列下：yum -y install apache
Setting up Install Process
Setting up repositories
....................................
Complete!
接下來配置apache，編輯Apache的設定檔，命令列下：vi /etc/httpd/conf/httpd.conf
#
# Don't give away too much information about all the subcomponents
# we are running. Comment out this line if you don't mind remote sites
# finding out what major optional modules you are running
ServerTokens OS　 ← 找到這一行，將“OS”改為“Prod”（在出現錯誤頁的時候不顯示伺服器作業系統的名稱）
↓
ServerTokens Prod 　 ← 變為此狀態
#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of: On | Off | EMail
#
ServerSignature On　 ← 找到這一行，將“On”改為“Off”
↓
ServerSignature Off　 ← 在錯誤頁中不顯示Apache的版本
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work. See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make
# redirections work in a sensible way.
#
#ServerName new.host.name:80　 ← 修改主機名稱
↓
ServerName www.linuxidc.com:80　 ← 根據實際情況修改，連接埠號碼保持預設的80
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs-2.0/mod/core.html#options
# for more information.
#
DirectoryIndex index.html index.html.var       ←找到這一行，
DirectoryIndex index.html index.php               ← 添加預設index.php檔案

Options Indexes FollowSymLinks　 ← 找到這一行，刪除“Indexes”，並添加“Includes”、“ExecCGI”
↓
Options Includes ExecCGI FollowSymLinks　 ← 允許伺服器執行CGI及SSI
#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
#AddHandler cgi-script .cgi　 ← 找到這一行，去掉行首的“#”，並在行尾添加“.pl”
↓
AddHandler cgi-script .cgi .pl　 ← 允許副檔名為.pl的CGI指令碼運行
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride None　 ← 找到這一行，將“None”改為“All”
↓
AllowOverride All　 ← 變為此狀態，允許.htaccess
#
# Specify a default charset for all pages sent out. This is
# always a good idea and opens the door for future internationalisation
# of your web site, should you ever want it. Specifying it as
# a default does little harm; as the standard dictates that a page
# is in iso-8859-1 (latin1) unless specified otherwise i.e. you
# are merely stating the obvious. There are also some security
# reasons in browsers, related to javascript and URL parsing
# which encourage you to always set a default char set.
#
AddDefaultCharset UTF-8　 ← 找到這一行，在行首添加“#”
↓
#AddDefaultCharset UTF-8　 ← 不使用UTF-8作為網頁的預設編碼
AddDefaultCharset GB2312　 ← 並接著添加這一行（添加GB2312為預設編碼）
<Directory "/var/www/icons">　 ← 找到這一個標籤，並在標籤中更改相應選項
Options Indexes MultiViews　 ← 找到這一行，將“Indexes”刪除
↓
Options MultiViews 　 ← 變為此狀態（不在瀏覽器上顯示樹狀目錄結構）
AllowOverride None
Order allow,deny
Allow from all
</Directory>
命令列下:  chkconfig httpd on　 ← 設定HTTP服務自啟動
                     chkconfig --list httpd
                     httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off 　 ← 確認2--5為on的狀態就OK
                      /etc/rc.d/init.d/httpd start　 ← 啟動HTTP服務
                     Starting httpd: 　　　　　　　　　　　　　[ OK ]　← 啟動成功會出現OK
在瀏覽器瀏覽http://127.0.0.1  就可以看到測試頁面出現，表示安裝成功。3.安裝php
命令列下：yum -y install php
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
...............................
..................
Installing: php-pear ######################### [2/2]
Installed: php.i386 0:4.3.9-3.15
Dependency Installed: php-pear.i386 0:4.3.9-3.15
Complete!
安裝完畢，設定檔位於/etc/php.ini。可以修改配置。
4.測試環境
建立一個php檔案，
命令列下：vi  /var/www/html/test.php
輸入代碼:
<?php 
        $host = 'localhost'; 
        $user = 'root'; 
        $pwd = 'password'; 
        $link = mysql_connect( $host, $user, $pwd ); 
        if( !$link ){
               die( '串連失敗' ); 
        }else{ 
               echo '串連成功！'; 
        } 
        mysql_close( $link ); 
?> 
儲存退出，在瀏覽器下瀏覽 http://127.0.0.1/test.php ,可以看到php的相關資訊頁面。
至此，centos上利用yum線上快速搭建php環境就完成了。
