基于ssh和wsadmin的远程websphere部署

在jenkins的自动化部署过程中，由于一些实际的情况导致websphere deployment的插件不好用，具体体现在：

1. 需要配置烦人的ssl证书，而且如果目标机器的证书和机器名不一致，会失败

2.会占用大量的自动化部署机器的资源，它本质是在部署机器上消耗资源来部署到目标机器上的

为了解决这个问题：

采用远程部署文件传送和远程部署的模式，基于的技术基础是ssh, wsadmin这两个技术（有人说wsadmin不好用，没有有效的输出，其实是误解，已经足够完善）

实现的步骤为：

1. 使用 SSH publisher的功能，对应的插件为：Publish Over SSH, 将本地的部署文件传送到目标机器的指定路径下

2. 使用 ssh remote execute command功能呢， 对应的插件为： SSH plugin, 在远程的websphere目标机器上执行 wsadmin的客户端脚本程序

对应的wsadmin执行脚本见附件  deploy.jacl

调用方法为：

uninstall 步骤->

sh /{your websphere install path}/AppServer/bin/wsadmin.sh -conntype SOAP uninstall {ear path} {application name} {ear file name} {target cell} {target node} {target server} {binding virtual host} -host {host}  -port {port} -user  {user} -passsword {password} -lang jacl -javaoption -f deploy.jacl

install 步骤->

sh /{your websphere install path}/AppServer/bin/wsadmin.sh -conntype SOAP install {ear path} {application name} {ear file name} {target cell} {target node} {target server} {binding virtual host} -host {host}  -port {port} -user  {user} -passsword {password} -lang jacl -javaoption -f deploy.jacl
