Q: about try_files and regex location

Server NGINX
1

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”

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;
}
