I had a MySQL server on my Ubuntu dev box (I use a tutorial "how to install a lamp on ubuntu" type of article) and I decided to install mariadb.

So I uninstall mysql and install mariadb.

~$ mysql --version
mysql  Ver 15.1 Distrib 10.0.3-MariaDB, for debian-linux-gnu (i686) using readline 5.1
~$ mysqld --version
mysqld  Ver 10.0.3-MariaDB-1~precise-log for debian-linux-gnu on i686 (mariadb.org binary distribution)

The installation worked fine, all my database worked fine except I get this error when I run the code:

Warning: mysqli::mysqli() [mysqli.mysqli]: Headers and client library minor version mismatch. Headers:50529 Library:100003 in /var/www/test.php on line 5

this is my php code:

  $mysqli = new mysqli("localhost", "root", "", "test");

  if (mysqli_connect_errno()) {
      printf("Connect failed: %s\n", mysqli_connect_error());
      exit();
  }

  $query = "SELECT * FROM test";

  if ($result = $mysqli->query($query)) {

      while ($row = $result->fetch_assoc()) {
          printf ("%s (%s)\n", $row["id"], $row["name"]);
      }
      $result->free();
  }

  $mysqli->close();

and the mysql info:

As far as I know everything there is ok. What's the problem?

Also, is MariaDB ready for production?

  • See this: How can I upgrade from MySQL to MariaDB? The problem is probably due to you had mysql 5.1 and the new installation is newer version (10.0). It may be solved if you run mysql_upgrade. Jun 27, 2013 at 13:31
  • @ypercube no success, I update my question. It didn’t worked Jun 27, 2013 at 13:33
  • @ypercube so you saying I should install version 5.5 instead of 10.0? Jun 27, 2013 at 13:35
  • 10.0 is afaik still in alpha stage. But the problem may not be that. MySQL 5.1 can be replaced by MariaDB version 5.1 5.2 or 5.3 without issues. MySQL 5.5 can be replaced by MariaDB 5.5, too. From mysql 5.1 to 10.0 (or to mariadb 5.5) it's a replacement and an upgrade. The problem may just be with the PHP libraries but I'm not sure how it can be resolved (still chances are better with maria 5.5 which is GA than 10.0 which is still in development.) You can also ask a question at their site, if noone asnwers here. Their developers there can give answer, for sure. Jun 27, 2013 at 13:41

Answers are here in the MariaDB knowledge base: https://kb.askmonty.org/en/installation-issues-with-php5/ - basically, PHP has been compiled vs the MySQL 5.5 library and you get a version mismatch warning - this is not an error and you can still run your code normally though. There are a number of ways to solve that, the most obvious is using mysqlnd which is a native PHP extension and is not linked vs. any of the old mysqlclient libraries.
