ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) Ubuntu
<p>I have checked status of mysql by <code>sudo service mysql status</code> and get the following output:</p>

<pre><code> mysql.service - LSB: Start and stop the mysql database server daemon
   Loaded: loaded (/etc/init.d/mysql; bad; vendor preset: enabled)
   Active: active (exited) since Fri 2016-07-22 15:06:35 IST; 11s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 4946 ExecStart=/etc/init.d/mysql start (code=exited, status=0/SUCCESS

Jul 22 15:06:35 ubuntu-lenovo systemd[1]: Started LSB: Start and stop the mysql 
</code></pre>

<p>But when I try it to run via terminal it says:</p>

<blockquote>
  <p>ERROR 2002 (HY000): Can't connect to local MySQL server through socket
  '/var/lib/mysql/mysql.sock' (13)</p>
</blockquote>

<p>When I try to run with host i.e. <code>mysql --host 127.0.0.1 -uroot</code> it says:</p>

<blockquote>
  <p>ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)</p>
</blockquote>

<p>I have tried almost every solution from SO.</p>
