su root // root用戶下操作
1：下載：wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.7.0.tar.gz
2：解壓：tar -zxvf elasticsearch-6.7.0.tar.gz 並修改成自己想要的名稱 mv es
3：添加es專用用戶：useradd elasticsearch
4：設置權限： chown elasticsearch:elasticsearch ./es -R // -R：遞歸文件夾中所有文件
5：進入config文件夾修改elasticsearch.yml
network.host: 192.168.0.1 IP修改爲實際訪問ip，可能啓動會報錯，直接將IP修改爲 0.0.0.0也可以
6：修改jvm.options // 根據實際情況進行修改
-Xms1g -Xms128m
-Xmx1g -Xmx128m
如果不切換用戶進行啓動會報一下錯誤，所以啓動時必須切換到elasticsearch添加的用戶

解決方法：切換爲root用戶執行：chown -hR elasticsearch ./es 然後重新切回es用戶

解決方法：在confg文件夾下elasticsearch.yml中修改爲network.host: 0.0.0.0
報錯：
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解決方法：切換root用戶，修改 /etc/sysctl.conf 文件最後添加一行
vm.max_map_count=262144
：wq 之後執行 sysctl -p // 從指定的文件加載系統參數
報錯：ERROR: bootstrap checks failed
解決：在elasticsearch.yml中配置bootstrap.system_call_filter爲false，要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
成功！！！！
