我最近把我的机器从Ubuntu 14.04升级到16.04。我面临着使用弹性搜索作为服务的问题。我安装了elasticsearch使用:

sudo apt-get install elasticsearch

Now sudo service elasticsearch status command shows me this result:

现在sudo服务elasticsearch状态命令显示如下结果:

elasticsearch.service - LSB: Starts elasticsearch

Jul 30 19:28:54 dimik systemd[1]: Started A search engine.
Jul 30 19:29:18 dimik systemd[1]: Started LSB: Starts elasticsearch.

Although Java is installed in my machine and I can start the server using this command.

尽管Java安装在我的机器中，我可以使用这个命令启动服务器。

sudo /usr/share/elasticsearch/bin/elasticsearch

I am kind of stuck here. Any help will be appreciated.

我被困在这里了。如有任何帮助，我们将不胜感激。

After setting up JAVA_HOME for root the error:

将JAVA_HOME设置为根错误后:

4 个解决方案

#1

I found the solution for this issue. The solution comes form this discussion thread- Can’t start elasticsearch with Ubuntu 16.04 on elastic's website.

我找到了解决这个问题的办法。解决方案来自于这个讨论线程——无法在elastic的网站上启动Ubuntu 16.04的弹性搜索。

It seems that to get Elasticsearch to run on 16.04 you have to set START_DAEMON to true on /etc/default/elasticsearch. It comes commented out by default, and uncommenting it makes Elasticsearch start again just fine.

似乎要在16.04上运行弹性搜索，您必须将START_DAEMON设置为true，在/etc/default/elasticsearch上。它会在默认情况下被注释掉，取消注释会让弹性搜索重新启动。

Be sure to use systemctl restart instead of just start because the service is started right after installation, and apparently there's some socket/pidfile/something that systemd keeps that must be released before being able to start the service again.

一定要使用systemctl restart而不是仅仅启动，因为服务在安装之后就开始了，而且显然还有一些socket/pidfile/一些systemd保存的东西必须在能够再次启动服务之前释放出来。

The problem lies on log files, "No java runtime was found."

问题在于日志文件，“没有找到java运行时。”

Jul 30 18:28:13 dimik elasticsearch[10266]: [warning] /etc/init.d/elasticsearch: No java runtime was found

Here's my solution to the problem.

这是我解决这个问题的办法。

Check elasticsearch init file

检查elasticsearch init文件

sudo nano /etc/init.d/elasticsearch

sudo nano /etc/init.d/elasticsearch

search for

搜索

. /usr/share/java-wrappers/java-wrappers.sh
find_java_runtime openjdk8 oracle8 openjdk7 oracle7 openjdk6 sun6 default
export JAVA_HOME

Check java-wrappers.sh file

检查java包装器。sh文件

sudo nano /usr/share/java-wrappers/java-wrappers.sh

sudo nano /usr/share/java-wrappers / java-wrappers.sh

Now you could see the warning comes from

现在你可以看到警告来自

#Displays a warning
java_warning() {
    echo "[warning] $0: $@" >&2;
}

Somehow, java directories are not listed in jvm-list.sh files
不知何故，java目录不在jvm-list中列出。sh文件

Now edit the jvm-list.sh file

现在编辑jvm-list。sh文件

sudo nano /usr/lib/java-wrappers/jvm-list.sh

Edit the line add your java directories files, in my case add /usr/lib/jvm/java-8-oracle*

编辑行添加java目录文件，在我的示例中是添加/usr/lib/jvm/java-8-oracle*

__jvm_oracle8="/usr/lib/jvm/jdk-8-oracle-* /usr/lib/jvm/jre-8-oracle-* /usr/lib/jvm/java-8-oracle*"

Now restart the service and check elasticsearch services

现在重新启动服务并检查elasticsearch服务

sudo systemctl restart elasticsearch
sudo systemctl elasticsearch status
curl -X GET "http://localhost:9200"

sudo systemctl重启弹性搜索sudo系统ctl弹性搜索状态curl -X获得“http://localhost:9200”

Hopes this would help

希望这将有助于

Open /etc/init.d/elasticsearch file in editor, Comment below lines

打开/etc/init.d/elasticsearch文件在编辑器中，注释在下行
```
. /usr/share/java-wrappers/java-wrappers.sh
find_java_runtime openjdk8 oracle8 openjdk7 oracle7 openjdk6 sun6 default
```
Set JAVA_HOME manually like so:

手动设置JAVA_HOME，如下所示:
```
export JAVA_HOME="/usr"
```
service elasticsearch start

服务elasticsearch开始

My problem was different, I started elasticsearch manually as root user, so some files were created but elasticsearch user cannot write on it.

我的问题不同，我以根用户的身份手动启动了elasticsearch，因此创建了一些文件，但用户无法在其上写入。

You can test running manually elasticsearch:

您可以测试运行手动弹搜索:

sudo -u elasticsearch /usr/share/elasticsearch/bin/elasticsearch \
 -Des.default.config=/etc/elasticsearch/elasticsearch.yml \
 -Des.default.path.home=/usr/share/elasticsearch \
 -Des.default.path.logs=/var/log/elasticsearch \
 -Des.default.path.data=/var/lib/elasticsearch \
 -Des.default.path.work=/tmp/elasticsearch \
 -Des.default.path.conf=/etc/elasticsearch

To fix on my machine I had to do:

为了修理我的机器，我不得不这样做:

rm -rf /var/log/elasticsearch/*
rm -rf /var/lib/elasticsearch/*
