如何在自定义路径中安装elasticsearch？

Question

我需要将 Elasticsearch 安装到路径 /opt/elasticsearch/ 以及该路径中的所有信息。我的意思是，我也需要在 opt 中放入配置路径。

https://www.elastic.co/guide/en/elasticsearch/reference/7.15/settings.html 这里说我可以设置 ES_PATH_CONF 和 ES_HOME 环境变量来更改安装和配置路径，但它不起作用。

rpm --install elasticsearch-7.15.0-x86_64.rpm --prefix=/opt/elasticsearch/ 这不是我需要的，也不会更改配置路径。

它在 /opt/elasticsearch 中创建了主目录，我得到了下一个结构，路径没有改变。它仍然需要 /usr/share/elasticsearch/bin/

中的执行箱

el6:~ # tree /opt/elasticsearch/ -d -L 3
/opt/elasticsearch/
├── lib
│   ├── sysctl.d
│   ├── systemd
│   │   └── system
│   └── tmpfiles.d
└── share
    └── elasticsearch
        ├── bin
        ├── jdk
        ├── lib
        ├── modules
        └── plugins

但我需要

el5:~ # tree /opt/elasticsearch/ -d -L 1
/opt/elasticsearch/
├── bin
├── config
├── data
├── jdk
├── lib
├── logs
├── modules
└── plugins

手动安装 mkdir /opt/elasticsearch/ && tar -xzf elasticsearch-7.15.0-linux-x86_64.tar.gz -C /opt/elasticsearch/ --strip-components 1 我需要我的结构。我制作了 systemd 服务

    [Unit]
    Description=Elasticsearch
    Documentation=https://www.elastic.co
    Wants=network-online.target
    After=network-online.target
    
    [Service]
    Type=notify
    RuntimeDirectory=elasticsearch
    PrivateTmp=true
    Environment=ES_HOME=/opt/elasticsearch
    Environment=ES_PATH_CONF=/opt/elasticsearch/config
    Environment=PID_DIR=/var/run/elasticsearch
    Environment=ES_SD_NOTIFY=true
    EnvironmentFile=-/etc/sysconfig/elasticsearch
    
    WorkingDirectory=/opt/elasticsearch
    
    User=elasticsearch
    Group=elasticsearch
    
    ExecStart=/opt/elasticsearch/bin/elasticsearch -p ${PID_DIR}/elasticsearch.pid --quiet
    
    # StandardOutput is configured to redirect to journalctl since
    # some error messages may be logged in standard output before
    # elasticsearch logging system is initialized. Elasticsearch
    # stores its logs in /var/log/elasticsearch and does not use
    # journalctl by default. If you also want to enable journalctl
    # logging, you can simply remove the "quiet" option from ExecStart.
    StandardOutput=journal
    StandardError=inherit
    
    # Specifies the maximum file descriptor number that can be opened by this process
    LimitNOFILE=65535
    
    # Specifies the maximum number of processes
    # Specifies the maximum number of processes
    LimitNPROC=4096
    
    # Specifies the maximum size of virtual memory
    LimitAS=infinity
    
    # Specifies the maximum file size
    LimitFSIZE=infinity
    
    # Disable timeout logic and wait until process is stopped
    TimeoutStopSec=0
    
    # SIGTERM signal is used to stop the Java process
    KillSignal=SIGTERM
    
    # Send the signal only to the JVM rather than its control group
    KillMode=process
    
    # Java process is never killed
    SendSIGKILL=no
    
    # When a JVM receives a SIGTERM signal it exits with code 143
    SuccessExitStatus=143
    
    # Allow a slow startup before the systemd notifier module kicks in to extend the timeout
    TimeoutStartSec=5000
    
    [Install]
    WantedBy=multi-user.target

但是它不启动，不崩溃，也不在 journalctl 中写入任何日志。

如何在 opt 中安装带有配置的 elasticsearch？

Answer 1

您可以使用 rpm 命令将 elasticsearch 安装到 /opt/elasticsearch，然后将配置文件从默认位置移动到您选择的位置，最后更改 ES_PATH_CONF 和 ES_HOME 环境变量到各自的新路径。

使用“手动”安装方法（通过下载 .tar.gz）时，您可以自由地将文件放在您想要的位置。 wget returns 404 因为 file/URL 不存在。 wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.15.0-linux-x86_64.tar.gz 应该是正确的。（你错过了 -linux）

Answer 2

唯一的方法是将 tar.gz 下载到您的目录中，然后手动添加所有环境变量，并构建和管理您自己的初始化脚本
