出现这个错误是因为，你的内存不足，解决办法，修改elasticsearch的配置文件

ysq@ubuntu:/usr/share/elasticsearch$ 安装后Elasticsearch不会自动启动。如何启动和停止Elasticsearch取决于您的系统是使用SysV init还是systemd（由较新的发行版使用）。您可以通过运行此命令来判断正在使用哪个：
ps -p 1
可以使用以下service命令启动和停止Elasticsearch ：
sudo -i service elasticsearch start
sudo -i service elasticsearch stop
如果Elasticsearch因任何原因无法启动，它将打印STDOUT失败的原因。可以在中找到日志文件/var/log/elasticsearch/。
