I have installed Jenkins on Apache container and started it, but whenever I am trying to access it using the URL http://localhost:8080/jenkins/ I am being redirected to the URL http://localhost:8080/jenkins/login?from=%2Fjenkins%2F and then the pop up attached appears asking me for the password, I pasted the password from the file that is mentioned, to the textbox it is not getting disappeared, unsure what to do.This is the pop up I am having while accessing the URL for the Jenkins

in my case the Jenkins was not unlocking with initial Admin password, then I thought of setting it up initially with Apache and then proceed with fixing the problem . The problem was in the number of slashes you put after ProxyPass and ProxyPassReverse entries.

Wrong entries 

ProxyRequests     Off
ProxyPreserveHost On
<Proxy http://localhost:8081/jenkins*>
   Order deny,allow
   Allow from all
</Proxy>
ProxyPass /jenkins http://localhost:8081/jenkins/ nocanon
AllowEncodedSlashes NoDecode
ProxyPassReverse /jenkins http://localhost:8081/jenkins/
ProxyPassReverse /jenkins http://your.hostname.domain/jenkins/
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"

Correct one which worked. 

ProxyRequests     Off
ProxyPreserveHost On
<Proxy http://localhost:8081/jenkins*>
   Order deny,allow
   Allow from all
</Proxy>
ProxyPass /jenkins http://localhost:8081/jenkins nocanon
AllowEncodedSlashes NoDecode
ProxyPassReverse /jenkins http://localhost:8081/jenkins
ProxyPassReverse /jenkins http://your.hostname.domain/jenkins
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"

Let me know your thoughts.

  • This worked for me on Linux Centos 7 having Apache as a reverse proxy for Jenkins running on 8081 since Apache already runs on 80 and 443 plus Tomcat running on 8080. Other useful source for me was https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+Apache – a4bike Jan 17 '20 at 17:52

use instructions from https://github.com/geerlingguy/ansible-role-jenkins/issues/50#issuecomment-214935354 and check an update below regarding locking access for anonymous users - worked for me today.

Shamelessly stolen from the link above:

  1. Create the file /var/lib/jenkins/jenkins.install.UpgradeWizard.state with one line 2.0

  2. Create the file /var/lib/jenkins/init.groovy.d/basic-security.groovy with the contents:

    #!groovy

    import jenkins.model.* import hudson.security.*

    def instance = Jenkins.getInstance()

    println "--> creating local user 'admin'"

    def hudsonRealm = new HudsonPrivateSecurityRealm(false) hudsonRealm.createAccount('admin','admin') instance.setSecurityRealm(hudsonRealm)

    def strategy = new FullControlOnceLoggedInAuthorizationStrategy() instance.setAuthorizationStrategy(strategy) instance.save()

  • Currently, it is 2.7.1... but adding JAVA_OPTS=-Djenkins.install.runSetupWizard=false also do the trick – jehon Feb 18 '21 at 15:11

you should deploy your jenkins to ......./tomcat/webapps/root then the jenkins url should like 'http://localhost:8080/login?from=%2F', when it is done,just copy code in the file ..../initialAdminPassword to Administrator password

Type your linux ipaddress:8080/jenkins/.So to unlock your jenkins type ifconfig and know your ip address

For example my ip address for centos is 192.168.2.4 I type 102.168.2.4:8080/jenkins/ in my web browser. Good luck
