LAMP的四個組成
瞭解LAMP堆疊的四個軟體層有助於故障排除過程,它允許我們看到每個層如何相互依賴。下面 下麪我們來具體瞭解一下LAMP的四個組成部分:
Linux:操作系統(OS)構成了我們的第一層。Linux爲堆疊模型奠定了基礎。所有其他圖層都在此圖層的頂部執行。
Apache:第二層由Web伺服器軟體組成,通常是Apache Web Server。該層位於Linux層之上。Web伺服器負責從Web瀏覽器轉換到正確的網站。
MySQL:我們的第三層是MySQL數據庫所在的位置。MySQL儲存可以通過指令碼查詢來構建網站的詳細資訊。MySQL通常與Apache /第2層一起位於Linux層之上。在高階設定中,MySQL可以解除安裝到單獨的主機伺服器。
PHP(Perl或Python):在它們之上的就是我們的第四層也是最後一層。指令碼層由PHP和/或其他類似的Web程式語言組成。網站和Web應用程式在此層中執行。
#安裝環境

#解壓縮原始碼包
[root@localhost opt]# tar zxvf nginx-1.12.2.tar.gz
#建立nginx使用者
[root@localhost nginx-1.12.2]# useradd -M -s /sbin/nologin nginx

#新增Nginx系統服務
爲了使用Nginx服務啓動,停止,過載方便,可以編寫基於Nginx服務控制檔案使用systemctl
[root@localhost nginx-1.12.2]# vim /lib/systemd/system/nginx.service

ExecStop = /usr/bin/kill -s QUIT $MAINPID
PrivateTmp = true
[Install]
WantedBy = multi-user.target
[root@localhost nginx-1.12.2]# chmod 754 /lib/systemd/system/nginx.service
[root@localhost nginx-1.12.2]# systemctl enable nginx.service
