LAMP搭建示例

lamp介紹

其實就是由Linux+Apache+Mysql/MariaDB+Php/Perl/Python的一組動態網站或者伺服器的開源軟體,除Linux外其它各部件本身都是各自獨立的程式,但是因為經常被放在一起使用,擁有了越來越高的相容度,共同組成了一個強大的Web應用程式平臺。

web伺服器工作流程

web伺服器的資源分為兩種,靜態資源和動態資源

  • 靜態資源就是指靜態內容,客戶端從伺服器獲得的資源的表現形式與原檔案相同。可以簡單的理解為就是直接儲存於檔案系統中的資源

  • 動態資源則通常是程式檔案,需要在伺服器執行之後,將執行的結果返回給客戶端

工作過程:當客戶端請求是靜態資源時,web伺服器會直接把靜態資源返回個客戶端。

    :動態資源則通過FastCGI協議與php伺服器聯絡,通過CGI程式的master程式排程worker程式來執行程式以獲得客戶端請求的動態資源,並將執行的結果通過FastCGI協議返回給httpd伺服器,httpd伺服器收到php的執行結果後將其封裝為http響應報文響應給客戶端。在執行程式獲取動態資源時若需要獲得資料庫中的資源時,由Php伺服器通過mysql協議與MySQL/MariaDB伺服器互動,取之而後返回給httpd,httpd將從php伺服器收到的執行結果封裝成http響應報文響應給客戶端。

cgi與fastcgi  

     CGI(Common Gateway Interface,通用閘道器介面),CGI是外部應用程式(CGI程式)與WEB伺服器之間的介面標準,是在CGI程式和Web伺服器之間傳遞資訊的過程。CGI規範允許Web伺服器執行外部程式,並將它們的輸出傳送給Web瀏覽器,CGI將web的一組簡單的靜態超媒體文件變成一個完整的新的互動式媒體。

      FastCGI(Fast Common Gateway Interface)是CGI的改良版,CGI是通過啟用一個直譯器程式來處理每個請求,耗時且耗資源,而FastCGI則是通過master-worker形式來處理每個請求,即啟動一個master主程式,然後根據配置啟動幾個worker程式,當請求進來時,master會從worker程式中選擇一個去處理請求,這樣就避免了重複的生成和殺死程式帶來的頻繁cpu上下文切換而導致耗時


 

lamp平臺搭建

環境說明:

系統平臺            IP 需要安裝的服務

centos8

redhat8

192.168.248.131 httpd-2.4
mysql-5.7
php
php-mysql

 

 

lamp平臺軟體安裝次序: httpd --> mysql --> php

yum源:

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo


#epel
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
