本文指导如何在基于Debian的Ubuntu系统上轻松安装Jenkins，并通过APT-get进行更新。介绍了创建JDK和JRE环境、使用wget下载密钥、配置apt源、安装Jenkins、升级至最新版本的方法。还提供了在云环境中部署Jenkins的指南，包括使用Juju部署到EC2、HPCloud、OpenStack等云平台。同时详细说明了如何将Jenkins与Apache或Nginx代理进行整合，确保Jenkins运行在端口8080下。

连上网络后安装jenkins非常容易：

https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

On Debian-based distributions, such as Ubuntu, you can install Jenkins through apt-get.

Recent versions are available in an apt repository. Older but stable LTS versions are in this apt repository.

You need to have a JDK and JRE installed. openjdk-6-jre and openjdk-6-jdk are suggested. As of 2011-08 gcj is known to be problematic - see https://issues.jenkins-ci.org/browse/JENKINS-743.

Please make sure to back up any current Hudson or Jenkins files you may have.

Installation

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins

Upgrade

Once installed like this, you can update to the later version of Jenkins (when it comes out) by running the following commands:

sudo apt-get update
sudo apt-get install jenkins

(aptitude or apt-get doesn't make any difference.)

What does this package do?

Jenkins will be launched as a daemon up on start. See /etc/init.d/jenkins for more details.
The 'jenkins' user is created to run this service.
Log file will be placed in /var/log/jenkins/jenkins.log. Check this file if you are troubleshooting Jenkins.
/etc/default/jenkins will capture configuration parameters for the launch.
By default, Jenkins listen on port 8080. Access this port with your browser to start configuration.

Deploying on Ubuntu in a cloud (EC2, HP Cloud, OpenStack)

The Ubuntu Jenkins maintainer also maintains the Juju charm deployment/management script for deployment in clouds. It's designed to make it easy to deploy a master with multiple slaves:

juju deploy jenkins 
juju deploy -n 5 jenkins-slave 
juju add-relation jenkins jenkins-slave

The default password for the 'admin' account will be auto-generated. You can set it using:

juju set jenkins password=mypassword

Always change it this way - this account is used by the charm to manage slave configuration. Then feel free to expose your jenkins master:

juju expose jenkins

Setting up an Apache Proxy for port 80 -> 8080

This configuration will setup Apache2 to proxy port 80 to 8080 so that you can keep Jenkins on 8080.
sudo aptitude install apache2
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod vhost_alias

do not do this next command if you already have virtual hosting setup that depends on the default site. See my comment below - danapsimer
sudo a2dissite default
Create a file called jenkins in /etc/apache2/sites-available

<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName ci.company.com
	ServerAlias ci
	ProxyRequests Off
	<Proxy *>
		Order deny,allow
		Allow from all
	</Proxy>
	ProxyPreserveHost on
	ProxyPass / http://localhost:8080/
</VirtualHost>

sudo a2ensite jenkins
sudo apache2ctl restart

Setting up an Nginx Proxy for port 80 -> 8080

This configuration will setup Nginx to proxy port 80 to 8080 so that you can keep Jenkins on 8080. Instructions originally found in a GitHub Gist from rdegges: https://gist.github.com/913102

Install Nginx.
```
sudo aptitude -y install nginx
```

Remove default configuration.

cd /etc/nginx/sites-available
sudo rm default

Create new configuration for Jenkins. This example uses cat, but you can use your favorite text editor. Make sure to replace 'ci.yourcompany.com' with your domain name.
Note: Sometimes your permissions (umask, etc) might be setup such that this won't work. Create the file somewhere else then copy it into place if you run into that problem.

sudo cat > jenkins
upstream app_server {
    server 127.0.0.1:8080 fail_timeout=0;
}

server {
    listen 80;
    listen [::]:80 default ipv6only=on;
    server_name ci.yourcompany.com;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://app_server;
            break;
        }
    }
}
^D # Hit CTRL + D to finish writing the file

Link your configuration from sites-available to sites-enabled:

sudo ln -s /etc/nginx/sites-available/jenkins /etc/nginx/sites-enabled/

Restart Nginx
```
sudo service nginx restart
```
