CentOS7——搭建LNMP環境(WordPress案例)
LNMP組成介紹
LNMP(Linux-Nginx-MySQL-PHP)網站架構是目前國際流行的Web框架,該框架包括:Linux操作系統,Nginx網路伺服器,MySQL資料庫,PHP編程語言,所有組成產品均是免費開源軟體,這四種軟體組合到一起,成為一個免費、高效的網站服務系統。
LNMP工作原理
瀏覽器發送http request請求到伺服器(Nginx),伺服器響應並處理web請求。如果是靜態文本直接返回,否則將腳本(PHP)通過介面傳輸協議(網關協議)PHP-FCGI(fast-cgi)傳輸給PHP-FPM(進程管理程式),然後PHP-FPM調用PHP解析器的其中一個進程PHP-CGI來解析php腳本信息。【PHP-FPM在啟動時啟動了多個PHP-CGI子進程,併發執行。】然後將解析後的腳本返回到PHP-FPM,PHP-FPM再通過fast-cgi的形式將腳本信息傳送給Nginx。伺服器再通過Http response的形式傳送給瀏覽器。瀏覽器再進行解析與渲染然後進行呈現。
WordPress介紹
WordPress 介紹 WordPress是一種使用PHP語言開發的博客平臺,用戶可以在支持PHP和MySQL 資料庫的伺服器上架設自己的網站。 也可以把WordPress 當作一個內容管理系統(CMS)來使用。 WordPress 是一個免費的開源項目,在GNU通用公共許可證下授權發佈。
構建LNMP+WordPress案例
環境配置
關閉防火牆
systemctl stop firewalld
systemctl disable firewalld
臨時關閉SELINUX
setenforce 0
永久關閉SELINUX(重啟生效)
echo SELINUX=disabled>/etc/selinux/config
echo SELINUXTYPE=targeted>>/etc/selinux/config
安裝Nginx
增加 Nginx 官方源
cat << EOF > /etc/yum.repos.d/nginx.repo

baseurl=http://nginx.org/packages/centos/\$releasever/\$basearch/
gpgcheck=1

EOF
EPEL 源中的 nginx.service 由於 KILL 參數問題,啟動後無法停止,不建議使用。
安裝Nginx
yum install -y nginx
備份Nginx配置文件
echo y|cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.default
修改 nginx.conf

最後,訪問http://伺服器地址:8080 進入博客安裝界面
如果無法訪問網站地址:
1.請確保伺服器的防火牆和SELINUX為關閉狀態,詳細操作請看基礎環境配置的關閉防火牆與SELINUX操作。
2.測試主機與伺服器的通信狀態是否正常
1.選擇語言模式為中文
2.填寫資料庫信息
3.填寫網站信息
4.訪問http://伺服器地址:8080 就可以看到博客已經運行起來了
- wordpress資料庫相關信息:
- 資料庫伺服器:localhost
- 資料庫埠:3306
- 資料庫名稱:wordpress
- 資料庫用戶名:wordpress
- 資料庫密碼:wordpress_password
