Jenkins （1、自动化发布war包、2、自动化发布nodejs）

1、持续集成javaweb

首先咱们需要安装一个 Jenkins，这个就不必多说了，晚上一搜索一大把，然后安装各种插件，配置各种环境变量，

今天我的实验环境是

使用Jenkins 拉取gitlap上项目的代码，然后自动编译并发布到tomcat中。

配置Jenkins

1、这里配置的就是你代码所存放的位置，还有你的项目名称和描述之类的

2、配置触发器所需执行的一些东西，我这里配置了一个定时检测拉取的动作。

3、配置tomcta

这里要注意，最好单独创建一个账号，并赋予相关权限

<!--
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="<must-be-changed>" roles="tomcat"/>
  <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>
-->

<!-- <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="adminadmin" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="upload" password="upload" roles="manager-gui,manager-script"/>
</tomcat-users>

构建并查看日志

点击开始构建，然后查看输出日志结果，如果没有报错，大概就没有啥问题，说下我这里遇到的一个坑

查看了一下大概报错原因，然后我将context关掉了，这个是否要求上下文路径，这个要看代码里pom文件里有没有强制要求，如果没有就不用写，

然后我清除了一下工作目录，自动部署成功日志输出也正常了，

最终效果

2、持续集成nodejs

nodejs相比java还要简单一些，Jenkins完成构建发送发布服务器直接执行就ok了

1、第一步跟java的一样，设置项目的一些必要参数，以及你的项目的git的地址

 2、选择你构建的环境，前提是你要装好nodejs，和Jenkins对nodejs支持的一下插件

我这里做的就是在Jenkins的目录下将项目安装并打包。

 3、推送到发布服务器，执行相应命令，来运行你的项目

这里如果比较简单的命令可以直接在  Exec command 里面填写，但是如果过多最好还是已脚本的形式，一个是便于修改，还有就是便于测试。

要记住一点就是，这个没有自动更新的功能，所以要设置，关闭老项目，清理旧的文件或者备份，并启动新的项目

脚本

我这里没有写日志，如果发生错误了，不便于排查，最好可以将脚本的执行结果打印到某一文件中方便查询排错。

cd /home
killall node
rm -rf  /home/protct/
unzip healthy_protect_server.zip -d /home/protct/
