  <p>brew services list shows below output</p>
  
  <pre><code>Name  Status  User         Plist
  mysql started &lt;username&gt; /Users/&lt;username&gt;/Library/LaunchAgents/homebrew.mxcl.mysql.plist
  </code></pre>
  
  <p>But when I run 'mysql' or 'mysqladmin -u root password '' I get error.</p>
  
  <pre><code>ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
  </code></pre>
  
  <p>Can anybody tell the issue here.</p>
