kinaba 安装踩坑： FATAL Error: [elasticsearch.url]: definition for this key is missing 转

安装

https://www.jianshu.com/p/875457cb8da6

操作系统：Linux

kibana 版本： 7.4.0

1. 在/etc/yum.repos.d/ 下新建 kibana.repo 配置 yum 源地址内容如下：

[root@localhost yum.repos.d]# cat kibana.repo
[kibana-7.x]
name=Kibana repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

2. 安装 kibana

sudo yum install kibana

3. 安装完成之后，kibana 的相关目录如下所示：

4. 修改配置文件，主要是添加 elasticsearch 的信息：

server.port: 5601
server.host: "127.0.0.1"
server.name: "tanklog"
elasticsearch.url: "http://127.0.0.1:9200"

5. 启动 kibana （由于 root 用户不能直接启动 kibana，可以新建一个用户专门用来管理 kibana，或者在启动命令后追加 --allow-root）

/usr/share/kibana/bin/kibana --allow-root

6. 然后会报错如下：

FATAL  Error: [elasticsearch.url]: definition for this key is missing

7. 经过一波操作之后，发现需要将 url 换成 hosts，配置文件需要设置为如下所示：

需要用： elasticsearch.hosts，而不是： elasticsearch.url

server.port: 5601
server.host: "127.0.0.1"
server.name: tanklog
elasticsearch.hosts: ["http://localhost:9200/"]
# elasticsearch.url: "http://localhost:9200"

8. kibana 本身没问题，启动成功时会出现如下日志：

9. 由于我的 elasticsearch 版本是7.3.2，与 kibana 版本不一致，所以启动过程中出现了 error, 需要升级 elasticsearch 版本为 7.4.0

升级 elasticsearch 版本

sudo yum -y install elasticsearch-oss

10. 启动 kibana，查看日志信息，发现有很多 warn

[warning][config][plugins][security] Generating a random key for xpack.security.encryptionKey. To prevent sessions from being invalidated on restart, please set xpack.security.encryptionKey in kibana.yml

根据 warn 提示，在 kibana.yml 里面添加缺失的属性内容

xpack.reporting.encryptionKey: "a_random_string"
xpack.security.encryptionKey: "something_at_least_32_characters"

启动 kibana，且将启动日志收集到指定文件

/usr/share/kibana/bin/kibana --allow-root > /var/lib/kibana/kibana.log &
