I am seeing some error like below in my nginx error log:

2012/04/20 11:51:52 [crit] 21437#0: \*2548 open()  
“/var/cache/nginx/fastcgi\_temp/5/00/0000000005” failed (13: Permission  
denied) while reading upstream, client: 139.112.144.210, server:  
[example.com](http://example.com),  
request: “GET /index.php HTTP/1.0”, upstream:  
“fastcgi://127.0.0.1:9000”,  
host: “[example.com](http://example.com)”, referrer: “[http://example.com/](http://example.com/)”

I have: user www-data; in my nginx.conf and  
the owners of the /var/cache/nginx/fastcgi\_temp/5/00 are ‘nginx:nginx’

How can I fix this?

Thanks

With chown(1), see “man chown” for details.

Probably they were created before you changed the nginx config file  
settings.

My concern was that when I have user www-data; mentioned in my config  
file,  
why is nginx creating files for fastcgi\_temp with user nginx and group  
nginx

I understand thats the default user:group while compiling was  
nginx:nginx  
but shouldn’t they be overridden by the option provided in nginx runtime  
configuration file?

They are overriden. But if you change user/group set in config you  
have to fix permissions on already created subdirs (or just remove  
them, nginx will re-create them with correct permissions).
