Elasticsearch最新版本是5.4，链接地址：https://www.elastic.co/downloads/elasticsearch

建议下载zip包，直接解压就可以使用了。

xxx@localhost program]$ unzip elasticsearch-5.4.1.zip

$  cd elasticsearch-5.4.1/bin

启动

$  ./elasticsearch

java.lang.UnsupportedOperationException: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed

 可能会看到以上的警告信息，不用管，使用最新的linux就不会报这个问题
