- 32 位 CentOS 6.7 安装 Elasticsearch 7（单机）
要注意的是 Kibana 最好与 ES 版本要契合。
下载地址：https://www.elastic.co/fr/downloads/kibana
修改 config/kibana.yml 配置文件：
修改为当前服务器 IP 和 ES 所在 IP。
Kibana 默认启动端口是 5601。
启动 Kibana：
[root@MiWiFi-R4CM-srv config]# cd ../bin/
[root@MiWiFi-R4CM-srv bin]# ./kibana
./kibana: line 29: /usr/local/develope/kibana/kibana-7.9.2-linux-x86_64/bin/../node/bin/node: cannot execute binary file
./kibana: line 29: /usr/local/develope/kibana/kibana-7.9.2-linux-x86_64/bin/../node/bin/node: Succes
这是因为程序和系统的版本位数不一致。我就在我本机安装 Kibana。重新下载并且修改配置后启动 Kibana：
结果又出现：
再进行设置：
修改完成后重新启动 Kibana，出现了异常：

有一个异常信息：
log [08:39:16.016] [warning][savedobjects-service] Unable to connect to Elasticsearch. Error: [resource_already_exists_exception] index [.kibana_task_manager_1/W77PCxPuTXSE9qMm0Jmg8Q] already exists, with { index_uuid="W77PCxPuTXSE9qMm0Jmg8Q" & index=".kibana_task_manager_1" }查看下这个索引是否存在：
的确是存在，那么将这个索引删除：
➜ bin curl -XDELETE -u elastic:changeme http://10.224.221.68:9200/.kibana_task_manager_1
{"acknowledged":true}%
查看是否删除成功：
再启动 Kibana，访问：
