Hi all, after install nginx using EPEL (yum install nginx) in CentOS  
5.5. I tried to start the server, but I got this error:

2011/01/18 15:56:58 [emerg] 2139#0: eventfd() failed (38: Function not  
implemented)  
2011/01/18 15:56:58 [alert] 2138#0: worker process 2139 exited with  
fatal code 2 and can not be respawn  
2011/01/18 16:00:06 [emerg] 2192#0: eventfd() failed (38: Function not

2011/01/18 16:00:06 [alert] 2191#0: worker process 2192 exited with  
fatal code 2 and can not be respawn  
2011/01/18 16:01:15 [emerg] 2261#0: eventfd() failed (38: Function not  
implemented)  
2011/01/18 16:01:15 [alert] 2260#0: worker process 2261 exited with  
fatal code 2 and can not be respawn

I need to compile the nginx instead using yum?  
Thanks a lot.

Your nginx binary was compiled with file AIO support and uses  
eventfd() syscall, but your kernel doesn’t have this syscall. You  
have to recompile nginx without --with-file-aio configure argument.
