Question

我已在Debian 7 (wheezy)中安装了Elasticsearch 6.x.我尝试从service elasticsearch start开始，但它给了我一条错误消息

root@debian:~# sudo -i service elasticsearch start
[FAIL] Starting Elasticsearch Server: failed!

我试着查看nano /var/log/elasticsearch/elasticsearch.log处的elasticsearch日志文件，我收到了此错误

我该如何解决这个问题？我已经安装了java，它是version javac 1.8.0_151

我的代码可能出现什么问题？ `

Answer 1

我在通过YUM安装了ElasticSearch 7.8的CentOS7 cPanel服务器上遇到了相同的问题。根据{{3}}，我执行了以下操作：

在ES_JAVA_OPTS="-Djna.tmpdir=/var/lib/elasticsearch/tmp"中设置/etc/sysconfig/elasticsearch
mkdir -p /var/lib/elasticsearch/tmp
chown -R elasticsearch.elasticsearch /var/lib/elasticsearch/tmp

Answer 2

转到/ etc / sysconfig / elasticsearch
添加ES_JAVA_OPTS =“ - Djna.tmpdir = / var / lib / elasticsearch / tmp”
启动elasticsearch。
你现在可以看到在/ var / lib / elasticsearch /.
此文件夹应具有“elasticsearch”用户
使用namei -l / var / lib / elasticsearch
dr-xr-xr-x root root / drwxr-xr-x root root var drwxr-xr-x root root lib drwxr-x --- elasticsearch elasticsearch elasticsearch

我希望你的问题能得到解决。

Answer 3

检查/tmp/目录的权限。它必须有noexec。

/tmp需要exec才能支持JNA。解决方法是在elasticsearch sysconfig文件中指定tmp目录。

像export JAVA_OPTS="-Djava.io.tmpdir=$ES_HOME/tmp"

这样的东西

确保有$ES_HOME/tmp目录且elasticsearch用户具有写入权限。

我遇到了这个问题，因为我使用的是强化操作系统，也因为默认的umask是0027。

Answer 4

从命令提示符运行时， Windows 10 上发生了同样的问题：

unable to load JNA native support library, native methods will be disabled.

要解决此问题，只需使用管理员权限运行 elasticsearch.exe 即可（单击开始 - ＆gt;键入＆＃34;命令＆＃34; - ＆gt;右键单击＆＃34;命令提示符＆＃34; - ＆gt;选择＆＃34;以管理员身份运行＆＃34;）

Answer 5

好的，我找到了解决方案。显然我的vm内存存储（RAM）是1 GB - 2 GB，所以我将我的VM的RAM容量增加到至少4GB，然后我重启机器。弹性搜索开始工作得很好。

Answer 6

以下对我有用的

PUT your_index_name/_settings
    {
    "index": {
    "blocks": {
    "read_only_allow_delete": "false"
    }
    }
    }

我点击了以下链接：

Answer 7

在Ubuntu 18.04上，解决方案是

sudo systemctl编辑--full elasticsearch.service

添加一行

Environment = ES_JAVA_OPTS =“-Djava.io.tmpdir = / var / lib / elasticsearch / tmp”

在vi中使用-x退出

重新启动服务

sudo systemctl重新启动elasticsearch.service

无法加载JNA本机支持库Elasticsearch 6.x.
