如何在自定義路徑中安裝elasticsearch？

我需要將 Elasticsearch 安裝到/opt/elasticsearch/包含此路徑中所有資訊的路徑。我的意思是，我也需要將配置路徑放入 opt 中。

https://www.elastic.co/guide/en/elasticsearch/reference/7.15/settings.html它在這里說我可以設定ES_PATH_CONF和環境ES_HOME變數來更改安裝和配置路徑，但它不起作用。

rpm --install elasticsearch-7.15.0-x86_64.rpm --prefix=/opt/elasticsearch/ 這不是我需要的，也不會改變配置路徑。

它在 /opt/elasticsearch 中創建主目錄，我得到下一個結構并且路徑不會改變。它仍然需要 /usr/share/elasticsearch/bin/ 中的執行 bin

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

但是我需要

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

手動安裝 mkdir /opt/elasticsearch/ && tar -xzf elasticsearch-7.15.0-linux-x86_64.tar.gz -C /opt/elasticsearch/ --strip-components 1 我需要我的結構。我做了 systemd 服務

    [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

但它不會啟動，不會崩潰，也不會在 journalctl 中寫入任何日志。

如何在 opt 中使用配置安裝 elasticsearch？

uj5u.com熱心網友回復：

您可以/opt/elasticsearch使用您的rpm命令安裝 elasticsearch ，然后將組態檔從它們的默認位置移動到您選擇的位置，最后將ES_PATH_CONF和ES_HOMEenv 變數更改為它們各自的新路徑。

使用“手動”安裝方法（通過下載 .tar.gz）時，您可以自由地將檔案放在您想要的位置。wget回傳 404，因為檔案/URL 不存在。wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.15.0-linux-x86_64.tar.gz應該是正確的。（你不見了-linux）

uj5u.com熱心網友回復：

唯一的方法是將 tar.gz 下載到您的目錄中，然后手動添加所有環境變數，并構建和管理您自己的 init 腳本
