搭建過程中出現的問題
elasticsearch啟動過程中報錯【1】
ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

解決辦法
#修改config/elasticsearch.yml下約第23行，放開node.name注釋，可更改名稱
node.name: node-1
elasticsearch啟動過程中報錯【2】
ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
解決辦法
#打開第68行注釋，ip替換host1等，多節點請添加多個ip地址，單節點可寫按默認來
#配置以下三者，最少其一
#[discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes]
cluster.initial_master_nodes: ["node-1"] #這里的node-1為node-name配置的值
無法通過外部ip訪問elasticsearch
解決辦法
#修改config/elasticsearch.yml下約第55行,修改為當前es地址或0.0.0.0
network.host: 0.0.0.0
Failed to clear cache for realms [[]]
暫無解決辦法，官方github上已經有人提issue了
[status][plugin:spaces@7.1.1] Status changed from yellow to green - Ready
這個問題只會出現在單體ELK中，無需理會
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解決辦法：
臨時解決辦法：切換root用戶執行如下命令
# sysctl -w vm.max_map_count=262144
永久解決辦法：在 /etc/sysctl.conf文件最后添加一行
# echo "vm.max_map_count=262144" >> /etc/sysctl.conf
# sysctl -p #使修改立即生效
查看修改結果：
# sysctl -a|grep vm.max_map_count
顯示：
vm.max_map_count = 262144
ERROR: bootstrap checks failed
memory locking requested for elasticsearch process but memory is not locked
這是因為設置了鎖定內存參數bootstrap.memory_lock=true，這里給出本人之前的筆記鏈接https://www.cnblogs.com/hellxz/p/11009634.html
docker版本的數據目錄與日志目錄持載到本地無法啟動，提示Permission Denied
解決辦法：
添加容器環境變量TAKE_FILE_OWNERSHIP=true
