Premise: I am super ignorant about suexec & C, but this snippet of code in
suexec.c seems to be the one returning the error:
if (getcwd(cwd, AP_MAXPATH) == NULL) {
log_err("cannot get current working directory\n");
exit(111);
}
if (userdir) {
if (((chdir(target_homedir)) != 0) ||
((chdir(AP_USERDIR_SUFFIX)) != 0) ||
((getcwd(dwd, AP_MAXPATH)) == NULL) ||
((chdir(cwd)) != 0)) {
log_err("cannot get docroot information (%s)\n",
target_homedir);
exit(112);
}
}
As far as I can see, this is what it tries to do:
- save the current working dir to 'cwd'
- change dir to "target_homedir", that should be in this
case /var/www/webapp1
- change dir to AP_USERDIR_SUFFIX, that if not re-defined should be
"public_html" (#define AP_USERDIR_SUFFIX "public_html" in suexec.h)
- set the variable 'dwd' (docroot working directory) to the above
- change dir back to cwd (current working directory)
So I'd try to add a public_html directory and see how it goes.
Hope that helps!
Luca
