1：我按照文档先部署了一个站点，使用的是jar 包的方式，我将jar 包pull 到服务器后，修改了jar包里面的application.yaml 的数据库连接信息，我将datasource 替换为自己的MySQL 链接，此时启动jar 包，已可以正常访问站点了。
2：按照第一点的思路，我将jar包cp一份，修改了jar包application.yaml 的端口，将8090修改为8091，同时datasource设置为与第一点的MySQL 链接一致，只不过数据库不一样，此时我启动cp 后的jar包，报错如下：

大致看了一下，应该是datasource 的连接问题，我想证实下一台服务器可以部署多个吗？ 如何操作呢？
