你好，同学，如果要自动化部署，包括使用jekins的话，那就需要装一下maven。

防火墙可以相同，这个就看我们两个服务器是否配置一样的啦。以服务器对外的可以相同。另外你要看一下mysql部署在哪里，关于mysql的防火墙ip和端口还是要单独开放一下的，还有redis。不可能两个tomcat都装mysql对吧。

前端代码部署在这两个或者其他机器都没影响的，因为我们是前后端分离的。通过nginx做桥梁整合。

如果是本地tomcat访问redis完全正常，但是如果他俩在两台机子上就会出现以下错误，应该不是iptables 安全组的问题，因为我用本地redis-cli访问云上的redis没任何问题

polo哦

防火墙只需要开放相应的接口即可，一般来说就是你安装了什么软件需要怎么设置安全组就那样设置就好了，两个tomcat不同服务器可以通过哦nginx进行负载均衡啊，只是ip不再是指定同一个ip不同端口，而是可能不同ip不同端口（个人理解）
