一、deploy插件

在jenkins中发布application到远端有很多方法，除了publish over ssh外还有个插件deploy.hpi也可以实现。

插件下载地址：

插件安装方法：  点击：Jenkins(三)---Jenkins初始配置和插件配置
             或手动转到 http://www.cnblogs.com/horizonli/p/5331970.html

二、配置启用插件前需要对远程端的容器进行环境初始化（这里以tomcat为例）

1.tomcat能正常启动

2.tomcat能在web界面使用用户登录到app manager

1）配置增加tomcat用户：

2）添加用户和角色

3）登录tomcat manager

登录后如果能看到下面的界面表示配置正确

三、使用deploy插件发布war包到远程容器（这里以tomcat为例）

在系统设置中配置maven/jdk/git 可以参考：Jenkins(三)---Jenkins初始配置和插件配置（除去七 SSH这一节）

启动插件

打开之后填写

这里单独说下war包的路径和界面：

在后台看是这样的：

从前台看这样的：

界面地址：

这个地址就是用设置的用户和密码登录后的界面地址如下图：

四、利用deploy插件发布application到远程主机

1.首先确保远程主机上的tomcat能正常启动并能使用用户登录到application管理界面

2.再进行构建操作

3.如下图所示构建成功

4.测试是否发布成功

4.1检查tomcat manager页面

4.2web界面查看

====================================================================================

遇到的问题总结：

问题一：部署app的时候，tomcat出现“403/401 for URL: http://172.16.18.192:8090/manager/text/list” 和The username you provided is not allowed to use the text-based Tomcat Manager (error 403)

问题点： tomcat用户配置文件

解决方案：检查用户名和密码是否正确是否添加了用户角色和权限.

问题二（最常见）：部署完app后会出现内存溢出"java.lang.OutOfMemoryError: PermGen space"

问题点：tomcat的虚拟机内存不足，需要设置更大的内存

解决方案：1.找到tomcat路径，用编辑器打开catalina.sh，在“echo "Using CATALINA_BASE: $CATALINA_BASE"”上面加入以下行：

JAVA_OPTS="-server -XX:PermSize=64M -XX:MaxPermSize=128m

2.用脚本重启tomcat服务器，再部署。

重启tomcat示例脚本：

#!/bin/bash
#Time
log_time=`date +[%Y-%m-%d]%H:%M:%S`
