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
  1

• 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 
  1

• 增加的内容

  vm.max_map_count=655360
  1

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

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
  1
  2

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

  2

• 或者

  rsync -avl /home/top/opensearch top@10.168.2.86:/home/top/
  rsync -avl /home/top/opensearch top@10.168.2.87:/home/top/

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 &
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”,

  “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”
  }
• 7. 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
