阿里云EDAS在本地CentOS7.5 系统搭建测试环境，部署配置中心以及部署多个war包

参考阿里云的EDAS开发文档： 使用 Ali-Tomcat 开发应用

我们自己在内网搭建CentOS7 的测试环境，需要的资源如下：

1. Ali-Tomcat
2. Pandora 容器
3. EDAS 配置中心安装包

假设我们要在内网的一台CentOS7 的PC机上部署shop.war、goods.war、user.war，
如何实现？看下面的步骤：

1.安装配置中心（查看服务列表、状态，实现服务的注册、发现）：

a). 从前面所需资源链接下载配置中心，通过ftp等工具放到CentOS机器上，启动
b). 启动 EDAS 配置中心将会占用此台机器的 8080 和 9600 端口，因此确认 8080 和 9600 端口未被使用。

2.安装Ali-Tomcat、Pandora容器：

通过ftp等工具把前面链接下载的Ali-Tomcat、Pandora容器放到CentOS机器上，并且把Pandora 容器放到Ali-Tomcat的deploy目录下解压，最终目录路径如下：

3.配置中心需要设置hosts里面的域名映射：本机ip jmenv.tbsite.net
4.本次需要部署三个war包，所以要再复制2个如上所示的taobao-tomcat-7.0.59并重命名文件夹，或者不重命名（放到不同目录下）。

由于都是独占式部署的，所以每个taobao-tomcat 启动后的端口不能一样，需要修改每个tomcat目录下面的conf里面的server.xml，改掉其中的Server port、Connector port、redirectPort这三个端口，保证三个taobao-tomcat的这个配置都不一样。

5.由于每个Ali-Tomcat启动都需要实例化一个Pandora，默认端口是12200，会出现第一个war包启动后，
其服务可以正常出现在配置中心的服务列表中，后续的war包都无法正常启动部署，因为端口冲突，
所以在启动tomcat时要配置JVM参数制定这个端口：在每个taobao-tomcat里面的bin目录，添加一个setenv.sh文件，这个会在启动tomcat时自动被调用，
设置如下内容（注意其中的端口号，三个tomcat里面的配置需要不一样，否则无法正常启动）：

#!/bin/sh#!/bin/sh
#添加JVM选项
JAVA_OPTS=" -Dhsf.server.port=12205 "

有个小插曲：这三个tomcat里面配置的hsf服务端口，不要刚好只是相差1（比如可以分别设置为12210/12220/12230），
因为一个服务会占用两个端口，一个是上面这个配置文件配置的，还要占用顺延递增一个端口号，比如下图：

如果因为这个端口冲突，会导致taobao-tomcat启动失败，日志如下（实例内容可能会不一样，这里因为用到了redis所以打印的出错的是redis日志）：

更准确的日志，可以从taobao-tomcat的logs/localhost.log.2018-10-11 日志查看，例如：

6.最后，把三个war包分别放到taobao-tomcat的deploy目录，跟taobao-hsf.sar目录同级，依次启动配置中心、三个tomcat即可
