Jenkins重置安全配置

Jenkins在配置全局安全配置中忘记配置账号admin权限导致全部账号都只有普通权限，解决方法以下,将以下几行删除，而后重启再登录就恢复到了默认状态。

# 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
