The following web servers are known to work under MkLinux:
    Boa
    Roxen
    Apache
    XS-httpd 2.3
    Cern httpd
 
Of these, Boa probably uses the least system resources: http://www.boa.org 
 
There may be other web servers that will run too.
 
Visit http://www.xnet.com/~blatura/linapp1.html#system and

Apache 1.2 (b7), not at any of the ppc archives, compiles right
 out of the box, painlessly.

Apache 1.2b10 compiles without a problem. See
http://www.apache.org  for your closest mirror. 

Ben Laurie's Apache-SSL patches for Apache 1.2b10 
(http://www.algroup.co.uk/Apache-SSL/ ) also work fine. 

SSLeay 0.6.6(http://www.psy.uq.oz.au/~ftp/Crypto/ ) - 
which provides the underlying crypto to Apache-SSL -
 also compiles OK...
