Red Hat Bugzilla – Bug 615702
mod_userdir seems to not be useable because of selinux problems
Last modified: 2010-07-29 11:42:59 EDT
Description of problem:
It seems that lighttpd's mod_userdir doesn't work with selinux.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install lighttpd
2. Create a file "/etc/lighttpd/conf.d/aaa-local.conf" with with:
server.modules += ("mod_userdir")
userdir.path = "public_html"
3. lighttpd start
4. create public_html, alter permissions and run restorecon. The setup I have is...
ls -lhdZ / /home /home/doug /home/doug/public_html/
dr-xr-xr-x. root root system_u:object_r:root_t:s0 /
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home
drwxr-xr-x. doug doug unconfined_u:object_r:user_home_dir_t:s0 /home/doug
drwxrwxr-x. doug doug unconfined_u:object_r:httpd_user_content_t:s0 /home/doug/public_html/
5. service lighttpd start
6. Try and access http://server/~doug with a web browser.
An error is logged to /var/log/audit/audit.log:
type=SYSCALL msg=audit(1279379090.094:288): arch=40000003 syscall=195 success=no exit=-13 a0=941d6d0 a1=bf8b3040 a2=a3fff4 a3=93e7a20 items=0 ppid=1 pid=5269 auid=500 uid=496 gid=490 euid=496 suid=496 fsuid=496 egid=490 sgid=490 fsgid=490 tty=(none) ses=7 comm="lighttpd" exe="/usr/sbin/lighttpd" subj=unconfined_u:system_r:httpd_t:s0 key=(null)
The files in the user's public html directory.
It works as expected if selinux is disabled and the computer is rebooted. So, I think I've found the problem, but I have no idea about how to go about fixing it.
First question before I start looking into this : Have you executed the following?
setsebool -P httpd_enable_homedirs=on
I've tested on RHEL5 and it fails, but after changing the above, it works. Note that I also needed to add the following, so maybe lighttpd is being denied lookups for the home directory :
userdir.basepath = "/home/"
This would be another problem, maybe worth debugging, but you don't seem to be having it.
