title: How-to-fix-“username-is-not-in-the-sudoers-file.-This-incident-will-be-reported”
body: <p>I want to enable the mod_rewrite on Apache, I used Putty to access the server on my windows OS. 
  I logged in using my username and password, My friend said that I should have root access to enable the mod_rewrite, so he advice me to type sudo su after I successfully log in. So I added sudo su command and it asked me a password again, so I type my password but I got an error.</p>
  
  <pre><code>[myusername] is not in the sudoers file.the incident will be reported
  </code></pre>
  
  <p>So maybe anyone here could help me. </p>
