说明

  • 基于Elasticsearch7.10.2 的 opensearch-1.1.0

硬件服务器

  • 10.168.2.87
  • 10.168.2.88
  • 10.168.2.89

1.环境准备 (每台都需要做)

1.1创建用户(root用户操作)

  • useradd top

1.2 修改用户密码(root用户操作)

  • passwd top

1.3 赋予用户sudo权限(root用户操作)

  • 修改命令

    chmod -v u+w /etc/sudoers
    sed -i 's#.*top.*##g' /etc/sudoers
    sed -i 's#root.*ALL=(ALL).*ALL#root  ALL=(ALL)  ALL \ntop   ALL=(ALL)  ALL#g' /etc/sudoers
    chmod -v u-w /etc/sudoers
    

1.4 安全limits文件限制

  • 修改文件

    vim  /etc/security/limits.conf
    
  • 增加的内容

    * soft nofile 65536
    * hard nofile 65536
    

最后几行加上 需要增加的部分

1.5 系统文件限制

  • 修改文件

    vim  /etc/sysctl.conf 
    
  • 增加的内容

    vm.max_map_count=655360
    

最后几行加上 需要增加的部分(最后几行加上)

1.6 载入指定配置

  • 修改文件

    [top@node85 .ssh]$ sudo sysctl -p
    [sudo] top 的密码:
    vm.max_map_count = 655360
    
  • 结果如图

1.7 重启

  • 执行命令

    sudo reboot
    

2.opensearch安装参考

官网下载地址

2.1 下载安装包:

  • 执行命令

    mkdir /home/top/opensearch
    cd /home/top/opensearch
    wget http://10.168.2.60:35000/opensearch-1.1.0-linux-x64.tar.gz
    

3.OpenS安装

3.1 解压OpenS安装包

  • 执行命令

    cd /home/top/opensearch
    tar -xzvf opensearch-1.1.0-linux-x64.tar.gz
    

3.2 创建数据目录、日志目录

  • 执行命令

    mkdir /home/top/opensearch/data -p
    mkdir /home/top/opensearch/logs -p
    

3.3 删除安装包

  • 执行命令

    rm -rf opensearch-1.1.0-linux-x64.tar.gz
    ln -s opensearch-1.1.0/ opensearch
    

3.4分发配置及安装目录

  • 执行命令

    rsync -avl /home/top/opensearch u86:/home/top 
    rsync -avl /home/top/opensearch u87:/home/top
    
  • 或者

    rsync -avl /home/top/opensearch [email protected]:/home/top/
    rsync -avl /home/top/opensearch [email protected]:/home/top/

    #
    # Use a descriptive name for the node:

plugins.security.disabled: true

5. 启动OpenS集群

  • 此操作需要在各个节点上运行
/home/top/opensearch/opensearch/bin/opensearch -d -p /home/top/opensearch/pid >/dev/null 2>&1 &

6. 检测是否启动完成集群

  • [top@localhost ~]$ curl -X GET ‘http://10.168.2.85:9200/’
  • {
    “name”: “node85”,
    “cluster_name”: “es-top”,
    “cluster_uuid”: “v7M5HemdSvmFjVPhEAlhig”,
    “version”: {
    “number”: “7.10.2”,
    “build_flavor”: “default”,
    “build_type”: “tar”,
    “build_hash”: “93d5a7f6192e8a1a12e154a2b81bf6fa7309da0c”,
    createTime: 2021-11-30T19:13:45+08:00
    updateTime: 2021-11-30T19:13:45+08:00
    “build_snapshot”: false,
    “lucene_version”: “8.9.0”,
    “minimum_wire_compatibility_version”: “6.8.0”,
    “minimum_index_compatibility_version”: “6.0.0-beta1”
    },
    “tagline”: “You Know, for Search”
    }
    1. 其他
根据当前机器的大小修改分配给es的内存
  • 文件位置:vim /home/top/es/elasticsearch-7.10.2/config/jvm.options

-Xms1g =>修改成想要的内存数
-Xmx1g =>修改成想要的内存数
