selinux-nginx-rhel

SELinux Nginx policy for RHEL/CentOS.

Modified from http://sourceforge.net/projects/selinuxnginx/

Tested on CentOS 6.5

Installation

$ sudo yum install selinux-policy-devel selinux-policy-targeted
$ git clone https://github.com/jahrmando/selinux-nginx-rhel.git
$ cd selinux-nginx-rhel/nginx
$ make
$ semodule -i nginx.pp

Relabel the filesystem

$ touch /.autorelabel
$ reboot

Make sure nginx is running as nginx_exec_t

$ ls -Z /usr/sbin/nginx
-rwxr-xr-x. root root system_u:object_r:nginx_exec_t:s0 /usr/sbin/nginx

Check the audit logs to see if nginx is being denied.

$ audit2why -al

No output is good. If there are denials, modify the policy as necessary.

Troubleshooting

HTML Directories

if you have others directories for your html files you have to put the context httpd_sys_content_t in that directory. For example:

$ semanage fcontext -a -t httpd_sys_content_t "/home/www(/.*)?"
$ restorecon -R -v /home/www/

Sockets

If you are working in nginx with sockets..

upstream test {
    server unix:/var/run/apps/test-file.sock fail_timeout=0;
}

then you have to do this:

$ semanage fcontext -a -t nginx_var_run_t "/var/run/apps(/.*)?"
$ restorecon -R -v /var/run/apps/
