title: fail to start mysql(mariadb)
body: <p>i have been spending hours figuring out problems in connection mysql to use mariadb eventually. here's a situation.</p>
  
  <p>situation: </p>
  
  <p>1.i use macbook, and i am not that familiar with computer programming.
  i tried to connect java eclipse and mariadb. so i looked it up online.
  and at the same time, i opened up terminal and started my mysql using</p>
  
  <pre><code>mysql.server start
  </code></pre>
  
  <p>and it worked. and i was supposed to download mariaddb.2.2 jar something to connect it with eclipse, but i mistakenly downloaded "mariadb-10.2.12-osx10.13-x86_64.pkg" and installed it. and i also typed</p>
  
  <pre><code>mysql.server stop
  </code></pre>
  
  <p>and all that kind of things. lots and lots of things so that i can`t even remember
  after i found out i downloaded the wrong things, i felt like this is way beyond my skills, so i jumped back to play with mariadb.</p>
  
  <p>i opened up terminal and typed</p>
  
  <pre><code>mysql.server start
  </code></pre>
  
  <p>and termial keeps showing me this until now</p>
  
  <pre><code>.180322 00:04:47 mysqld_safe Logging to '/usr/local/var/mysql/sinjinhos-MacBook-Air-146.local.err'.
  180322 00:04:47 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
  . ERROR! 
  </code></pre>
  
  <p>i still think that this tragedy started beacause i installed mariadb again...
  i literally tried everything and still couldn`t figure it out.
  please help me!!</p>
