Welcome. Here You will find step-by-step installation guide for SA:MP CMS. Remember, that We are not responsible for any damages caused by script. Alos script is released "as it is".
If You agree, let's begin installation.
a) Go to app/Config folder and find file called database.php
b) On the end of file, You should see database config. You have to fill up 4 fields marked as: Database Host [1], Database Login [2], Database Password [3], Database Name [4]. The [1] field in most cases should be localhost. If it isn't working - see Your server config.
c) Now open core.php which is placed in the same folder where You have found database.php file.
d) Go to line 226 and You should see line:
"Configure::write('Security.salt', 'DYhG93b0qyJIJVd8ffjsdXSSWwvniR2G0FgaC9mi');"
It's very important to change DYhG93b0qyJIJVd8ffjsdXSSWwvniR2G0FgaC9mi string to some randomly generated string. Do the same thing with line 231 - here You can use only digits!
Why You have to do that? It's connected directly with security system implemented by CakePHP.
e) Now we will configure Your SA:MP connection settings. Go to folder app/Controller and open ServersController.php file. There You will find these lines:
$this->set('server_ip', '178.19.105.66');
$this->set('server_port', 9114);
First line is for server IP, second for server port. Remember that You have to enter port without ' symbols.
f) Now go to app/View/Layouts folder and open file called default.ctp. Find line 21 and 22. First line is Your site title - change it to Yours server name. Second line is url of Your site. You have to change that value too, otherwise You won't be able to make next step.
g) This step is VERY important. Open Your site and click on login button. Use default login settings for admin - login: admin, password: 123456. If Your login is succesfull, go to User Managment and click on Edit button next to admin nickname. You HAVE TO change password from default to Your own. If you won't do that, everyone will be able to access admin functions of Your site. You can also change username.
Remember, that You can't delete this account via site. Also other admins added after this acount won't be able to edit/delete this account. It's connected with security aspects. Don't try to delete this account.
If You have done all of this steps, You can check if SA:MP CMS connected to Your SA:MP server by navigating to Server tab.
