Linux（Ubuntu16.04）下安裝Jenkins
jenkins官網https://pkg.jenkins.io
這是Jenkins的Debian軟件包存儲庫，用於自動安裝和升級。要使用此存儲庫，請先將密鑰添加到系統中：
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -然後追加下列內容到/etc/apt/sources.list文件中（apt命令下載時會找下面的地址）
deb https://pkg.jenkins.io/debian-stable binary /
即： sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary / >> /etc/apt/sources.list'
更新您的本地包索引，然後最後安裝Jenkins：
sudo apt-get update sudo apt-get install jenkins
安裝jenkins後
sudo /etc/init.d/jenkins start //jenkins服務開啓 注意端口號是否被佔用（8080）
sudo /etc/init.d/jenkins status //查看jenkins服務開啓狀態
sudo /etc/init.d/jenkins stop //jenkins服務關閉查看進程中的jenkins
ps aux | grep jenkinsjenkins的日誌（/var/log/jenkins/jenkins.log）
more /var/log/jenkins/jenkins.log再開啓jenkins服務，查看下日誌是否啓動成功！
7.進入選擇插件安裝界面，選擇第一個（Install suggested plugins）
8.插件安裝完成之後，需要創建第一個用戶
9.創建用戶之後，就可以使用jenkins了
附：Tomcat下部署Jenkins (win7)
直接下載jenkins.war，網上說放到tomcat的webapps下，直接啓動tomcat便可，但是訪問
http://localhost:8080/jenkins 出現了以下問題,且出現類似於下面的截圖（網上的圖），jenkins啓動失敗！
注：我使用的是apache-tomcat-7.0.75，jekins是2.56版本，jdk是1.8.0_131

at o網上找了些博客資料如下：
http://www.mkyong.com/java/java-unsupported-major-minor-version-51-0/
大概說的是major.minor version 52.0 = JDK 1.8 / 8 （可我係統java就是1.8）
