Jenkins 安装在 Ubuntu 上，使用 Vagrant - 无 Z293C9EA246FF9985986ZF 访问

Question

I've been trying to install Jenkins on ubuntu using Vagrant. Even though I am not getting any errors along the way I am not able to open http://localhost:8080

Here's my steps:

1. Install Vagrant and Virtual Box on MAC
2. Create a folder for the vagrant
3. vagrant init bento/ubuntu-16.04
4. nano Vagrantfile - delete the hasztag from the port forwarding to 8080
5. Vagrant up
6. Vagrant ssh

Install git:

1. Sudo apt-get install git
2. Git --version

Installing Java:

1. sudo apt update
2. Sudo apt-get upgrade
3. sudo apt install default-jdk
4. sudo apt install default-jre

Install Jenkins:

1. wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

2. sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'

3. sudo apt-get install -y jenkins --allow-unauthenticated

4. To check the password: vi /var/log/jenkins/jenkins.log

5. To start Jenkins: systemctl start jenkins systemctl status jenkins

When I start the jenkins server I can do telnet 127.0.0.1 8080 but when I turn it off it doesn't work. Any idea why I cannot access GUI using the browser?

Try in ubuntu to do "curl http://localhost:8080", if response is not some error code page, like 4xx/5xx, check firewall and allow traffic on port 8080. Therefore try to access Jenkins from Host Machine.
