linux - ubuntu 上的 Elastic Enterprise/App search 安装问题

Question

我正在运行一个在虚拟机中运行 ubuntu 的 vagrant box(使用 Laravel Homestead box)

我正在尝试安装 Elastic App-search 产品。

第一个要求是安装 Elasticsearch，我已经做过多次了。我做了以下步骤: https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

sudo apt-get install apt-transport-https

echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list

sudo apt-get update && sudo apt-get install elasticsearch

我正在使用 systemd 配置:

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

我正在运行 curl localhost:9200，一切正常。

接下来我尝试安装 elastic app search。 https://www.elastic.co/guide/en/app-search/current/installation.html#installation-self-managed .其中没有针对 debian 系统的说明。但它确实有一个 .deb 安装文件。我下载了文件并将其放在我的项目路径中。

我在文件上运行了 dpkg -i，它似乎已经安装好了。当我运行命令检查文件位置时，它显示如下:

 dpkg -L enterprise-search

我不确定这是不是正确的位置？我希望它和我的 elasticsearch 安装在同一个地方，但实际上我不确定。我完成了安装过程的所有后续步骤并运行:./usr/share/enterprise-search/bin/elasticsearch

但这给了我错误:

Could not find java in PATH

我对此感到非常困惑，因为主要的 elasticsearch 安装工作并且还需要 java？我还希望它也能在 systemd 自动启用的情况下运行，并且我希望它在企业搜索启动/停止时可用。不确定如何处理。

看起来它是 Debian 软件包，所以它可以安装在 ubuntu 上，但有些地方可能有所不同。我会说你可以:

1. 为此只需切换到使用 debian VM(在这里你可以获得一个 vagrant:https://app.vagrantup.com/debian/boxes/stretch64)
2. 调试。据我所知，该包在运行之前先运行 elasticsearch-env 。 Java 是这样查找的:

 if [ ! -z "$JAVA_HOME" ]; then
   JAVA="$JAVA_HOME/bin/java"
   JAVA_TYPE="JAVA_HOME"
 else
   if [ "$(uname -s)" = "Darwin" ]; then
     # macOS has a different structure
     JAVA="$ES_HOME/jdk.app/Contents/Home/bin/java"
   else
     JAVA="$ES_HOME/jdk/bin/java"
   fi
   JAVA_TYPE="bundled jdk"
 fi

 if [ ! -x "$JAVA" ]; then
     echo "could not find java in $JAVA_TYPE at $JAVA" >&2
     exit 1
   fi

所以我建议在启动脚本中设置 JAVA_HOME(或在运行二进制文件之前)，看看是否有帮助。
