安裝完成

編輯配置文件及啟動腳本

vim /etc/init.d/nginx 復制如下內容。來源https://coding.net/u/aminglinux/p/aminglinuxbook/git/blob/master/D15Z/etc_init.d_nginx

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"

prog="Nginx"
start()
{
echo -n $"Starting $prog: "

• chmod 755 /etc/init.d/nginx

• chkconfig --add nginx

• chkconfig nginx on

• cd /usr/local/nginx/conf/

• mv nginx.conf nginx.conf.bak

• vim nginx.conf 寫入如下內容。來源https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf

}

• /usr/local/nginx/sbin/nginx -t //檢查是否有語法錯誤

• /etc/init.d/nginx start //啟動nginx服務

• netstat -lntp |grep 80 //查看監聽80端口狀態

測試php

vi /usr/local/nginx/html/1.php //加入如下內容
<?php
echo "test php scripts.";
?>
curl localhost/1.php //測試能否解析php

12.7 默認虛擬主機

• mkdir /usr/local/nginx/conf/vhost //創建虛擬主機目錄

• cd /usr/local/nginx/conf/vhost

• vim default.conf //加入如下內容
  server
  {
  listen 80 default_server; #有這個標記的就是默認虛擬主機
  server_name aaa.com;
  index index.html index.htm index.php;
  root /data/wwwroot/default;
  }

• mkdir -p /data/wwwroot/default/

• echo “This is a default site.”>/data/wwwroot/default/index.html

• /usr/local/nginx/sbin/nginx -t

• /usr/local/nginx/sbin/nginx -s reload #重新加載nginx

支持include語法

12.8 Nginx用戶認證

• vim /usr/local/nginx/conf/vhost/test.com.conf #寫入如下內容
  server
  {
  listen 80;
  server_name test.com;
  index index.html index.htm index.php;
  root /data/wwwroot/test.com;

  location / #用戶認證相關配置
  {
  auth_basic "Auth";
  auth_basic_user_file /usr/local/nginx/conf/htpasswd;
  }
  }

創建密碼文件

• yum install -y httpd #安裝apache,如果沒有,有可跳過該步

• /usr/local/apache2.4/bin/htpasswd -c /usr/local/nginx/conf/htpasswd Auth_user #指定用戶認證的用戶名

  
  

• /usr/local/nginx/sbin/nginx -t

• /usr/local/nginx/sbin/nginx -s reload #重新加載nginx

• mkdir /data/wwwroot/test.com

• echo “test.com”>/data/wwwroot/test.com/index.html

測試

通過curl測試
curl -x127.0.0.1:80 test.com -I #狀態碼為401說明需要驗證
curl -uAuth_user:123 -x127.0.0.1:80 test.com -I #訪問狀態碼變為200

針對目錄的用戶認證
location /admin/
{
auth_basic "Auth";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}

針對某個頁面的用戶認證
location ~ admin.php
{
auth_basic "Auth";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}

12.9 Nginx域名重定向

• 編輯/usr/local/nginx/conf/vhost/test.com.conf為如下內容:
  server
  {
  listen 80;
  server_name test.com test1.com test2.com;
  index index.html index.htm index.php;
  root /data/wwwroot/test.com;
  if ($host != 'test.com' ) {
  rewrite ^/(.*)$ http://test.com/$1 permanent;
  }
  }
