Error reporting when installing jenkins offline

1. Unable to enter jenkins

error phenomenon

After entering the initial password for offline installation, the card is stuck on the page where offline installation is detected. The page displays two options, configure proxy and skip plug-in installation

After clicking to skip the plug-in installation, a 403 error is reported and the jinkens cannot be entered

Solve the error

The reason is that jenkins has been installed on the server before

delete old jenkins files

find / -iname jenkins | xargs -n 1000 rm -rf 

restart jenkins

2. Unable to create credential

error phenomenon

Jenkins is installed offline. After entering jenkins, an error 403 is reported when creating a credential

The reason is that the CSRF security verification problem of the new version of Jenkins leads to

Modify the configuration file

I modified the jenkins home directory during installation, so the configuration file location is `/data/CICD/config.xm

vim config.xml

  <crumbIssuer class="hudson.security.csrf.DefaultCrumbIssuer">
    <excludeClientIPFromCrumb>false</excludeClientIPFromCrumb>
  </crumbIssuer>

Modify false to true

  <crumbIssuer class="hudson.security.csrf.DefaultCrumbIssuer">
    <excludeClientIPFromCrumb>true</excludeClientIPFromCrumb>
  </crumbIssuer>

restart jenkins
