Ubuntu 16.04 安裝 Jenkins

安裝、啓動並配置jenkins服務

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

systemctl status jenkins.service

● jenkins.service - LSB: Start Jenkins at boot time
Loaded: loaded (/etc/init.d/jenkins; bad; vendor preset: enabled)

cat /etc/services | grep 8080

http-alt 8080/tcp webcache # WWW caching service
http-alt 8080/udp

從日誌看出Jenkins在默認狀況下從8080端口啓動。在這個系統端口中，8080已經在使用中了。因此在/etc/default/jenkins.修改Jenkins默認端口設置

修改/etc/default/目錄下面的jenkins文件，將如下內容

# port for HTTP connector (default 8080; disable with -1)
HTTP_PORT=8080
修改成：
# port for HTTP connector (default 8080; disable with -1)
HTTP_PORT=8089

啓動中止Jenkins

sudo service jenkins start
sudo service jenkins stop

訪問路徑：http://localhost:8089

其餘說明

• 安裝路徑：/var/lib/jenkins
• 日誌路徑：/var/log/jenkins/jenkins.log

2、Jenkins初始化配置
1）解鎖Jenkins

這裏須要/var/lib/jenkins/secrets/initialAdminPassword的密碼解鎖Jenkins
而後把密碼複製進去。
說明：按照彈框提示，找到該initialAdminPassword文件，我這裏使用Docker啓動Jenkins，而且把jenkins_home目錄掛載到我磁盤指定目錄，因此這裏我只須要複製/Users/wanyang3/jenkins_home/initialAdminPassword便可，若是非掛載方式Docker啓動，則須要進入容器內根據提示路徑找到該文件。

2）定製 Jenkins

說明：這裏若選擇Install suggested plugins安裝，那麼jenkins就會給你推薦安裝一些頗有用的插件，若選擇Select plugins to install安裝，那麼就須要本身根據業務須要選擇性安裝某些插件。

3）建立第一個管理員用戶

說明：這裏建立第一個管理員用戶，也能夠不設置，直接點擊「Continue as admin」，進入jenkins之後再設置。

新建Pipeline Job Demo
1）建立一個pipeline job
