eAccelerator configuration for Cloudlinux + fcgi

I have a CloudLinux server 6.4 x86_64 with fcgi handler. I have compiled eaccelerator with EasyApache, then edit /usr/local/lib/php.ini and set the settings for eaccelerator, but the phpinfo page does not show the changes after restart apache.

The default shm_size is 16MB, I want to increase it to larger number. According to eaccelerator wiki, I need to change the kernel.shmmax, but my kernel.shmmax number is set 64GB already.

I have set "allowed_admin_path" and I can access the eaccelerator admin panel. From the panel, I can see the eaccelerator does cache scripts.

What's wrong with my settings? Thanks for any help.
