修改源代码
在Node的构造函数里面加一条日志，这样在服务节点启动时，就会打印该日志。
构建压缩包
linux
./gradlew :distribution:archives:linux-tar:assemble
mac
./gradlew :distribution:archives:darwin-tar:assemble
所有平台
./gradlew assemble
解压部署
压缩包位置
distributions/archives，默认是snapshot版本。
如果要去掉snapshot可以加下面参数构建
./gradlew assemble -Dbuild.snap-shot=false
解压文件，参考es7集群启动配置进行配置，启动
./bin/elasticsearch
可以看见修改的内容已经生效：
