An example wrapper follows. The 'uMsg()' calls are just home-brewed function
calls that output error messages. Substitute your own error messages:
/** wrapper BEGINS **/
#include
#include
#include "uUtil.h" /* for uMsg() */
void main( int argc, char *argv[] )
{
uid_t uid = your_web_user_uid_here;
gid_t gid = your_web_user_gid_here;
int ierr = 1;
char *p;
if( argc != 2 )
{
fprintf( stderr, "USAGE: %s WEB_ROOT\n", argv[0] );
fprintf( stderr, "WHERE: WEB_ROOT - is the root of the web tree\n" );
}
else
{
p = argv[1];
if( chdir(p) )
{
uMsg( U_FATAL, "chdir to %s failed: %S", p );
}
else if( chroot(p) )
{
uMsg( U_FATAL, "chroot to %s failed: %S", p );
}
else if( setuid(uid) != 0 )
{
uMsg( U_FATAL, "setuid failed: %S" );
}
else if( setgid(gid) != 0 )
{
uMsg( U_FATAL, "setuid failed: %S" );
}
else
{
execl( "/bin/httpd","httpd",(char *)0 );
uMsg( U_FATAL, "execl failed for httpd: %S" );
}
}
exit( ierr );
}
/** wrapper ENDS **/
Now you have to install your existing html files into your new tree. If
people have been using relative pathnames in their html files, then there
won't be many difficulties. In my case I just copied all necessary trees
into the new location (using korn-shell syntax):
cd /old_web_tree
for i in dir1 dir2 dir3 dir4 blahblahblah ; do
cp -r $i /wtree/$i
done
You will have to correct any html files that have full pathnames in their
