froxlor latest - mysql 8 support

bimmer · December 3, 2018

Hi All,

I just upgraded my server to mysql 8 with froxlor 0.9.38.7. It threw a couple mysql error during database creation so I decided to upgrade froxlor. However after the upgrade I can't even reach the login page due to a database error. Is it possible that froxlor latest is not compatible with mysql 8?? Or am I missing something?

Thanks a lot!

Hi,

dont know if this is the right thread to post:

I had the same Problem with a freh installation of Froxlor @mysql v8.

Had to rewrite the Installer:

From: (Line 645 to 663)

foreach ($mysql_access_host_array as $mysql_access_host) {
			$_db = str_replace('`', '', $this->_data['mysql_database']);
			$stmt = $db_root->prepare("
					GRANT ALL PRIVILEGES ON `" . $_db . "`.*
					TO :username@:host
					IDENTIFIED BY 'password'");
			$stmt->execute(array(
				"username" => $this->_data['mysql_unpriv_user'],
				"host" => $mysql_access_host
			));
			$stmt = $db_root->prepare("SET PASSWORD FOR :username@:host = PASSWORD(:password)");
			$stmt->execute(array(
				"username" => $this->_data['mysql_unpriv_user'],
				"host" => $mysql_access_host,
				"password" => $this->_data['mysql_unpriv_pass']
			));
		}

		$db_root->query("FLUSH PRIVILEGES;");

Replace with:

foreach ($mysql_access_host_array as $mysql_access_host) {
					
			//Create User	
			if (version_compare($version_server, '8.0.11', '>=')) {
				
				$stmt = $db_root->prepare("CREATE USER :username@:host IDENTIFIED BY :password");
				$stmt->execute(array(
					"username" => $this->_data['mysql_unpriv_user'],
					"host" => $mysql_access_host,
					"password" => $this->_data['mysql_unpriv_pass']			
				));

			} else {						
				$stmt = $db_root->prepare("
					GRANT ALL PRIVILEGES ON `" . $_db . "`.*
					TO :username@:host
					IDENTIFIED BY 'password'");
				$stmt->execute(array(
					"username" => $this->_data['mysql_unpriv_user'],
					"host" => $mysql_access_host
			));
				$stmt = $db_root->prepare("SET PASSWORD FOR :username@:host = PASSWORD(:password)");
				$stmt->execute(array(
					"username" => $this->_data['mysql_unpriv_user'],
					"host" => $mysql_access_host,
					"password" => $this->_data['mysql_unpriv_pass']
					));
				}						
		}
		// Ab dafür (DB -> Rolle -> User)
		$stmt = $db_root->prepare("CREATE ROLE 'Froxlor_Role'");
		$stmt->execute();

		$stmt = $db_root->prepare("GRANT ALL ON `" . $_db . "`.* TO 'Froxlor_Role'");
		$stmt->execute();

		foreach ($mysql_access_host_array as $mysql_access_host) {
			$stmt = $db_root->prepare("GRANT Froxlor_Role TO :username@:host");	
			$stmt->execute(array(
					"username" => $this->_data['mysql_unpriv_user'],
					"host" => $mysql_access_host
					));
			}

		foreach ($mysql_access_host_array as $mysql_access_host) {
                        $stmt = $db_root->prepare("SET DEFAULT ROLE Froxlor_Role TO :username@:host");
                        $stmt->execute(array(
                                        "username" => $this->_data['mysql_unpriv_user'],
                                        "host" => $mysql_access_host
                                        ));
                        }	
		
		if (version_compare($version_server, '8.0.11', '<')) {
		$db_root->query("FLUSH PRIVILEGES;"); 
		}

Some Info´s:

- I have used MySQL Roles

- Add User with GRANT only does not work anymore

- FLUSH PRIVILEGES is also obsolete.

For sure there are some possibilities to finetune some of the code.

hf with it

H,

going to test this as soon as possible.

Got some other errors going on with buster in a LXC-Container. App-Armor won`t let apache start.

I think you get the results at 1am.

here you are:

Hm, okay, patch is on its way...if you do not use latest developer version (git) just remove every occurance of NO_AUTO_CREATE_USER in our code

additional info:

NO_AUTO_CREATE_USER is removed in MySQL 8.0.11

thanks, removing it solved the problem. However with the old and the new version when I try to create a new database for a user this error occurs:

Now I tried to select all lines and inserted in a new file, named it as class.DbManagerMySQL.php and tried again.

The error is the same:

Maybe there is a different way to create user in Mysql 8?

d00p · December 4, 2018

no, this is the way, see https://dev.mysql.com/doc/refman/8.0/en/create-user.html

Can you debug what username the query uses? Any special characters in it?
