title: Error:mysqld.service: Start request repeated too quickly. On manjaro
body: <p>Yesterday I updated my manjaro. I had many problems since then.</p>
  
  <p>Firstly, I type</p>
  
  <pre><code>systemctl status mysqld.service
  </code></pre>
  
  <p>to start MySQL, but it errors out with</p>
  
  <pre><code>mysqld.service: Start request repeated too quickly.
  </code></pre>
  
  <p>I has found many suggestions but they doesn't work.</p>
  
  <p>I already have tried:</p>
  
  <ul>
  <li><p>Check the permission of the MySQL data directory using the below command. The ownership should be <code>mysql:mysql</code> and the directory permission should be 700.</p>
  
  <pre><code>ls -ld /var/lib/mysql/
  </code></pre></li>
  <li><p>Check the permission of databases inside the MySQL data directory using the below command. The ownership should be <code>mysql:mysql</code> for all the files inside that directory.</p>
  
  <pre><code>ls -lh /var/lib/mysql/
  </code></pre></li>
  <li><p>Check the listening network TCP ports using the command</p>
  
  <pre><code>netstat -ntlp
  </code></pre></li>
  <li><p>Check the MySQL log files for any error using:</p>
  
  <pre><code>cat /var/log/mysql/mysqld.log
  </code></pre></li>
  <li><p>Try to start MySQL using</p>
  
  <pre><code>mysqld_safe --defaults-file=/etc/my.cf
  </code></pre></li>
  </ul>
  
  <p>My Error:</p>
