[ensembl-dev] unable to start Ensembl server without httpd -X

[CLARK, MATTHEW]

Thanks for the response.

It turned out that the trouble was caused by the way I'd compiled other modules required in the httpd.conf. 
Initially I had used the exact configuration parameters on the website './configure --enable-deflate --prefix=/usr/local/Ensembl/apache2' then compiled the other requited apache modules individually using apxs.

The way which worked was to enable them like mod_deflate was during configuration: './configure --enable-deflate --enable-expires --enable-headers --enable-proxy --enable-rewrite --enable-proxy_http --prefix==/usr/local/Ensembl/apache2'


Thanks

Matt

Hi Matthew

Sorry for the delay in getting back to you - we were rather busy preparing for the release last month, then your email slipped down the list. Comments below...

That's correct - the absence of these parameters won't affect your mirror. However I've never seen these warnings before, so I'm not sure what the diagnosis is.

Definitely not the former, so I would think the latter - did you create a fresh compile of Apache with mod_perl support, as per our online instructions?

Cheers
