• /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解析
  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
  

• 安裝過程中遇到的問題:
  [root@kh-01 nginx-1.12.1]# chkconfig --add nginx
  服務 nginx 不支持 chkconfig
  
  
  原因是nginx配置文件中有錯誤,更正為如下圖後就OK了.
  

  12.7 默認虛擬主機

• vim /usr/local/nginx/conf/nginx.conf
• 把server{}這一部分先註釋掉,然後增加如下一行:
• include vhost/*.conf;
  
• mkdir /usr/local/nginx/conf/vhost //創建虛擬主機目錄
• cd /usr/local/nginx/conf/vhos
• 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

測試默認虛擬主機:

• curl localhost
• curl -x127.0.0.1:80 123.com
  

12.8 Nginx用戶認證

• 1.針對整個站點的用戶認證:

• 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;
  }
  }

• 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

• 測試用戶認證:
  (1)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
  
  (2)通過瀏覽器訪問測試
  編輯windows的hosts文件，然後在瀏覽器中訪問test.com會有輸入用戶、密碼的彈窗

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

• 3. 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;
  }

知識點:
/usr/local/nginx/sbin/nginx -s reload
重新加載時,如果配置文件有語法錯誤,它是不生效的,這樣就不會導致nginx服務停掉;而重啟的話/usr/local/nginx/sbin/nginx restart則可能會導致nginx服務因有錯誤而不能正常啟動.

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;
  }
  }
• 測試結果:
  
  知識點:
• server_name後面支持寫多個域名，這是和httpd不同的,httpd只能通過server alias來做到這一點.
• permanent為永久重定向，狀態碼為301，如果寫成redirect,則狀態碼為302.
