can not run elasticsearch as root：
不能使用root用户进行操作，需要创建一个用户，并把原来的目录的拥有者更改为该用户
adduser myuser
passwd myuser
chown -R myuser /mypath

max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
修改/etc/security/limits.conf
添加：elastic hard nofile 65536

max file size [67107840] for user [elastic] is too low, increase to [unlimited]
修改/etc/security/limits.conf
elastic soft fsize unlimited

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决：sysctl -w vm.max_map_count=262144

5：运行：
bin/elasticsearch
后台运行：bin/elasticsearch -d -p pidFile
会生成一个pidFile文件，记录pid
随系统启动：
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
