Jenkins重置安全配置

Jenkins在配置全局安全配置中忘記配置賬號admin權限導致全部賬號都只有普通權限，解決方法以下,將以下幾行刪除，而後重啓再登錄就恢復到了默認狀態。

# vim /var/lib/jenkins/config.xml
  <useSecurity>true</useSecurity>
  <authorizationStrategy class="hudson.security.LegacyAuthorizationStrategy"/>
  <securityRealm class="hudson.security.HudsonPrivateSecurityRealm">
    <disableSignup>false</disableSignup>
    <enableCaptcha>false</enableCaptcha>
  </securityRealm>
# systemctl restart jenkins
