title: I can't start MySQL on linux - Error mysqld_safe
body: <p>I found in many forums around the web, but I did not find my solution.
  When I start the service mysql in linux ubuntu server 12.04, I get this error:</p>
  
  <pre><code>root@stroke:/# mysqld_safe &amp;
  [1] 5789
  root@stroke:/# 131001 10:12:29 mysqld_safe Logging to syslog.
  131001 10:12:29 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
  131001 10:12:29 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
  </code></pre>
  
  <p>I've already given permission to the folder mysql, I've also tried to create a new password for the root mysql. But so far nothing has worked.</p>
  
  <p>Thanks for help.</p>
  
  <p>Some information:</p>
  
  <pre><code>root@stroke:/# /etc/init.d/mysql start
  Rather than invoking init scripts through /etc/init.d, use the service(8)
  utility, e.g. service mysql start
  
  Since the script you are attempting to invoke has been converted to an
  Upstart job, you may also use the start(8) utility, e.g. start mysql
  start: Job failed to start
