I want to setup moodle quiz for 30 concurrent users.My moodle instance will only have quiz module and certification module.I have diabled all the rest of the module. I am going to use Moodle 2.6 , PHP 5.3+ , APACHE server , Mysql as the database in same machine. I'll also use APC for caching. My server box will be Linux.(Ubuntu 12.04 or Centos 6). Can somebody tell me about the configuration of following.
1) APC configuartion
2) Apache configuration
3) Mysql configuration
4) Linux server configuration.
I already gone through all the discussion available on forums but I still need the help on this specific requirement. I also read in the moodle document that a moodle instance can server 10 to 20 concurrent user per 1 GB RAM but it depends upon server configuration. Please help me on this.
