  • ElasticSearch 命令行管理工具Curator

    一、背景


    elastic官网现在已经大面积升级到了5.x版本,然而针对elasticsearch的命令行管理工具curator现在仍然是4.0版本。

    刚开始找到此工具,深深的怕因为版本更迭无法使用,还好在试用之后,顾虑烟消云散。

    • 应用目的

    我主要用到了它删除数据的功能。因为直接通过curl命令删除数据需要输入密码,然而在利用<< EOF的方式也无法绕过密码校验。

    懒得自己写python脚本,既然已经有了对应工具,何不马上用起来。

     

    二、安装


    1、Signing Keyedit

    Download and install the public signing key:

    rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

    2、Repository Configurationedit

    Add the following in your /etc/yum.repos.d/ directory in a file with a .repo suffix, for example curator.repo

    Warning
    The repositories are different for CentOS/RHEL 6 and 7 due to library and path differences. Be sure to use the correct version for your system!

    RHEL/CentOS 6
    [curator-4]
    name=CentOS/RHEL 6 repository for Elasticsearch Curator 4.x packages
    baseurl=http://packages.elastic.co/curator/4/centos/6
    gpgcheck=1
    gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
    enabled=1
    RHEL/CentOS 7
    [curator-4]
    name=CentOS/RHEL 7 repository for Elasticsearch Curator 4.x packages
    baseurl=http://packages.elastic.co/curator/4/centos/7
    gpgcheck=1
    gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
    enabled=1

    3、Binary Package Installationedit

    Starting with version 4.1.2, Curator comes with a binary version. What this really means is that the source is compiled, and all required libraries are bundled with the curator binary, so there are no conflicts.

    There are separate binary packages for RedHat variants. The binary packages resulting from the creation process have been tested on CentOS 6 & 7, with a different binary for each. They may work on similar variants and/or derivatives, but they have not been tested.

    yum install elasticsearch-curator

    This will install the necessary files into /opt/elasticsearch-curator and make a symlink at /usr/bin/curator that points to the curator binary in the aforementioned directory.

    三、配置


    运行报错
    curator_cli     
    Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment.  Either run this under Python 2 or consult http://click.pocoo.org/python3/ for mitigation steps.
    This system lists a couple of UTF-8 supporting locales that
    you can pick from.  The following suitable locales where

    When used with Python 3 (and the DEB and RPM packages of Curator are compiled
    and bundled with Python 3), Curator requires the locale to be unicode. Any of
    the above unicode definitions are acceptable.
    To set the locale to be unicode, try:
    $ export LC_ALL=en_US.utf8
    $ curator_cli [ARGS]
    Alternately, you should be able to specify the locale on the command-line:
    $ LC_ALL=en_US.utf8 curator_cli [ARGS]
    Be sure to substitute your unicode variant for en_US.utf8
    配置修正
    vim /etc/profile
    #添加以下内容
    export LC_ALL=en_US.utf-8
    export LANG=en_US.utf-8
     
    source /etc/profile
     

    四、应用


    主要利用其删除功能,先展示下其命令行功能表:
