nginx之rewrite规则未加引号导致检查nginx语法报错

标签：文件中   directive   rect   RoCE   code   led   not   pre   The   

[root@test01 ~]# grep rewrite /usr/local/nginx/conf/vhost/img.test.conf 
   rewrite ^/.{4}[0-9]{4}[0-9]{8}/(.*)$ /uploads/picture/$1 last;

检查语法报错：

[root@test01 ~]# /usr/local/nginx/sbin/nginx -t
nginx: [emerg] directive "rewrite" is not terminated by ";" in /usr/local/nginx/conf/vhost/img.test.conf:8
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

错误原因：这是由于规则里有大括号“{ }”的符号，Nginx误以为这是规则的结尾，产生错误
解决的办法：把规则段使用单引号或者是双引号引起来

[root@test01 ~]# grep rewrite /usr/local/nginx/conf/vhost/img.test.conf 
   rewrite ‘^/.{4}[0-9]{4}[0-9]{8}/(.*)$‘ /uploads/picture/$1 last;

或者：

[root@test01 ~]# grep rewrite /usr/local/nginx/conf/vhost/img.test.conf 
   rewrite "^/.{4}[0-9]{4}[0-9]{8}/(.*)$" /uploads/picture/$1 last;
[root@test01 ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

此规则简单说明：

.{4}指的是任意4个字符，[0-9]{4}任意4个数字，[0-9]{8}任意8个数字

应用环境说明：
此服务器充当图片服务器，由nginx来提供服务，应用配置环境如下：

[root@test01 ~]# grep root /usr/local/nginx/conf/vhost/img.test.conf 
   root  /data/www/images;
[root@test01 ~]# ll /data/www/images/uploads/picture/2016/07/28/1469696883.jpeg 
-rw-r--r--. 1 root root 65824 Jul 28  2016 /data/www/images/uploads/picture/2016/07/28/1469696883.jpeg
[root@test01 ~]# ll /data/www/images/uploads/picture/2016/07/28/1520924032.png 
-rw-r--r--. 1 root root 89032 Mar 13 14:53 /data/www/images/uploads/picture/2016/07/28/1520924032.png
[root@test01 ~]# 

浏览器请求图片，此时图片正常显示：

http://img.test.com/MTEy114512345678/2016/07/28/1469696883.jpeg
http://img.test.com/MTEy114512345678/2016/07/28/1520924032.png
