标签:min   deb   连接失败   exce   访问   ofo   --   you   java   


环境: elasticsearch 6.5.2, java


连接失败

启动后当你 使用 curl http://localhost:9200 测试时,得到如下结果


Curl: (7) Failed connect to localhost:9200; Connection refused

这个问题一般是其他问题导致的,请看你启动日志,如果用的管理服务工具来启动的,则看它的日志,我这里是 systemctl ,然后命令以及输出结果是


root@localhost ~]# systemctl status elasticsearch
● elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Mon 2018-12-10 15:26:08 EST; 11min ago
     Docs: http://www.elastic.co

Dec 10 15:26:08 localhost.localdomain systemd[1]: Unit elasticsearch.service entered failed state.
Dec 10 15:26:08 localhost.localdomain systemd[1]: elasticsearch.service failed.

没有发现 java 环境

如上图错误细节,告诉我们没有java 相关环境,首先确认下 是否能 运行 java,不过不能,请配置Java环境然后source,具体请百度。

解决了java 环境问题,还需要将 java 可执行命令 放到 /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin 下的任意一个中, 这里放到 /usr/bin

命令: ln -s /usr/local/jdk1.8.0_XXX/bin/java /usr/bin/java

开始远程访问后,bootstrap checks failed

本地访问完全问题,然后开启远程后gg了, 直接上错误

我参考了基本问题,知道这是怎么回事,至于解决方式,就

security 问题

es 从6.3 以后就没有单独x-pack 组件了,全是是api, 可以参考官网:xpack-api

而没有付费是不能享受用户名密码登录了,没有付费 去看是这样的


GET _xpack/security/_authenticate


{
  "error": {
    "root_cause": [
      {
        "type": "security_exception",
        "reason": "current license is non-compliant for [security]",
        "license.expired.feature": "security"
      }
    ],
    "type": "security_exception",
    "reason": "current license is non-compliant for [security]",
    "license.expired.feature": "security"
  },
  "status": 403
}
