[mapserver-users] MapCache 1.2.0 and NGNIX 1.5 problem

Wed Oct 9 01:31:40 PDT 2013

Thanks for the point,

Indeed, using  strace command, I created a debug LOG to spawn-FGC and saw this:

22419 rt_sigaction(SIGPIPE, {SIG_DFL, [PIPE], SA_RESTORER|SA_RESTART, 0x3259032920}, {0x35d0006290, [], SA_RESTORER, 0x3259032920}, 8) = 0

22415 read(8, "\n", 4096)               = 1
22415 write(2, "\n", 1)                 = 1

22419 exit_group(99)                    = ?
22415 <... select resumed> )            = 1 (in [6])
22415 read(6, "", 4096)                 = 0

22415 write(3, "\1\6\0\1\0B\6\0Status: 403 Forbidden\r\nContent-Type: text/plain\r\n\r\n403 Forbidden\r\n\0\0\0\0\0\0\1\6\0\1\0\0\0\0\1\3\0\1\0\10\0\0\0\0\0\0\0\0\0\0", 104) = 104
22415 shutdown(3, 1 /* send */)         = 0
22415 select(4, [3], NULL, NULL, {2, 0}) = 1 (in [3], left {1, 999997})
22415 read(3, "", 1024)                 = 0
22415 close(3)                          = 0
22415 accept(0, 

I Google the error "Cannot get script name, are DOCUMENT_ROOT and SCRIPT_NAME (or SCRIPT_FILENAME) set and is the script executable?"  and there's not a clean response or solution.

So if you have any clue or idea to continue move forward I'll be very grateful.

Thanks in advance

Victor

You might want to check the spawn-fcgi logs. Note that there is no
place in the mapcache code that emits a 403 error, i.e. that 403 is
coming from something else than mapcache.
