Dear all,

please can you help me to fix the issue with try\_files an regex  
location, thank you.

I use

### 

sbin/nginx -V  
nginx: nginx version: nginx/1.1.4  
nginx: built by gcc 4.4.3 (Ubuntu 4.4.3-4ubuntu5)  
nginx: TLS SNI support enabled  
nginx: configure arguments: --with-debug --with-libatomic  
–without-http\_ssi\_module --without-http\_uwsgi\_module  
–without-http\_scgi\_module --without-http\_memcached\_module  
–with-http\_ssl\_module --user=nginx --group=nginx --prefix=server/nginx  
–with-http\_stub\_status\_module

### 

with the following config.

### 

http {  
server {  
…  
location ~ ^/(share|alfresco)(/res)?(.\*$) {  
alias /home/alfresco/alfresco-4.0.b/tomcat/webapps;  
try\_files $uri /$1$2 /$1$3 @alfresco;  
}

```
     location @alfresco {
       proxy_pass http://alfresco;
     }

```

}  
}

### 

I get the following error:

### 

2011/11/11 12:58:09 [error] 5618#0: \*33782 open()  
“/home/alfresco/alfresco-4.0.b/tomcat/webapps/share/components/document-details/document-link/home/al”  
failed (2: No such file or directory), client: xxx, server: xxx,  
request: “GET /share/components/document-details/document-links-min.js  
HTTP/1.1”, host: “xxx”, referrer:  
“[https://xxx/share/page/site/aleks-glossar/document-details?nodeRef=workspace://SpacesStore/985297e8-ff1b-4423-b6e9-8dacc0011196](https://xxx/share/page/site/aleks-glossar/document-details?nodeRef=workspace://SpacesStore/985297e8-ff1b-4423-b6e9-8dacc0011196)”

### 

Could it be that try\_files match on ‘/$1$2’ but the open call get  
‘/$1$3’ or something else?

attached the debug log.

The “alias” directive in your config replaces request part of path to  
file after  
successful “try\_files” check.

This is the bug in alias and try\_files interaction. Or, more  
strictly, such configuration should be rejected during testing  
configuration as it’s not really make sense: alias within regex  
location specifies full path to a file, and try\_files is  
meaningless here.

You probably mean to use “root” instead, i.e.

```
location ~ ^/(share|alfresco)(/res)?(.*$) {
    root /home/alfresco/alfresco-4.0.b/tomcat/webapps;
    try_files $uri /$1$2 /$1$3 @alfresco;
}

```
