# 一、需求 #

> Jenkins大多数情况下都是用来部署Java项目，上一篇博客已经写了自动打包Java项目，但在现实应用中，Jenkins很强大的，可以做到自动打包发布Java项目。这篇文章，将引导大家完成完整的Java项目(自动发布代码功能）！

# 二、实验环境 #

> ![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java]

# 三、实验步骤 #

## 1.搭建tomcat 服务(在192.168.22.129服务器上) ##

### （1）先安装jdk1.8 ###

> jdk和tomcat 下载地址： [https://pan.baidu.com/s/1URk88Tp2Io0eUEMo1WpoCg][https_pan.baidu.com_s_1URk88Tp2Io0eUEMo1WpoCg]  
> 提取码：fcuo

### （2）解压安装 ###

> mkdir -p /usr/local/java  
> tar -zxvf jdk-8u91-linux-x64.tar -C /opt  
> mv /opt/jdk1.8.0\_91/ /usr/local/java

### （3）修改环境变量 ###

> vim /etc/profile  
> export JAVA\_HOME=/usr/local/java/jdk1.8.0\_91  
> export PATH=$PATH:$JAVA\_HOME/bin

### （4）刷新环境变量，使其生效 ###

> source /etc/profile

### （5）查看jdk版本号 ###

> java -version

### （6）解压安装tomcat ###

> tar xvfz apache-tomcat-8.5.16.tar.gz  
> mv apache-tomcat-8.5.16 /usr/local/tomcat8

### （7）修改tomcat配置 ###

> vim /usr/local/tomcat8/conf/tomcat-users.xml \#设置访问manager用户名，密码  
> 在倒数第二行插入：  
> <role rolename="admin"/>  
> <role rolename="admin-gui"/>  
> <role rolename="admin-script"/>  
> <role rolename="manager"/>  
> <role rolename="manager-gui"/>  
> <role rolename="manager-script"/>  
> <role rolename="manager-jmx"/>  
> <role rolename="manager-status"/><user name="admin" password="abc123" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />

> vim /usr/local/tomcat8/webapps/manager/META-INF/context.xml \#设置允许连接tomcat的网段

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 3]

### （8）启动tomcat ###

> /usr/local/tomcat8/bin/startup.sh \#启动服务  
> netstat -anpt | grep ":8080" \#查看端口

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 4]

### （9）网页访问tomcat ###

## 4.Java项目配置（在Jenkins服务器上） ##

### （1）新建任务 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 7]

### （2）先输入任务名称，再点击构建maven项目，最后点击确定 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 8]

### （3）填写源码管理，svn拉取代码地址，用户登录名 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 9]  
![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 10]

### （4）在构建设置中，填写打包命令（打包命令仅供参考，以公司svn配置为准） ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 11]

### （5）设置构建后操作，完成后保存 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 12]

## 5.构建Java项目（在Jenkins服务器上） ##

### （1）配置完成后，在该项目界面，点击立即构建 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 13]

### （2）查看构建过程和构建结果 ###

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 14]

## 6.在tomcat服务器查看war包 ##

![Jenkins自动部署发布Java代码（完整教程）][Jenkins_Java 15]

## 7.网页验证测试网站（在宿主机上） ##

# 总结： #

> 1.这篇博客是在上一篇博客的基础上完成的，请先阅读 [https://blog.51cto.com/13760351/2381229][https_blog.51cto.com_13760351_2381229]  
> 2.tomcat安装，可以用脚本安装，可参考我的博客 [https://blog.51cto.com/13760351/2339399][https_blog.51cto.com_13760351_2339399]  
> 3.tomcat服务要部署在另一台服务器上面，和Jenkins不是一台服务器，不能弄错了。  
> 4.Jenkins 安装部署Java项目，并非一帆风顺，期间出现了很多坑，这些过程，我会在后面博客中详细写出来，避免大家入坑，请叫我“填坑侠”！
