Elasticsearch 7.6.2安装-RPM方式

Elasticsearch

安装准备

服务器准备

为搭建ElasticSearch集群，准备了三台服务器，主机IP分别为：

服务器IP 系统版本
192.168.1.107 Centos6.5
192.168.1.108 Centos6.5
192.168.1.109 Centos6.5

调整系统参数

内核参数调整

  1. vim /etc/sysctl.conf
  2. # 增加下面的内容
  3. fs.file-max = 65536
  4. vm.max_map_count = 262144
  5. # 执行命令
  6. sysctl -p

资源参数调整

  1. vim /etc/security/limits.conf
  2. # 修改
  3. * soft nofile 65536
  4. * hard nofile 65536
  5. * soft nproc 4096
  6. * hard nproc 4096
  7. elasticsearch soft memlock unlimited
  8. elasticsearch hard memlock unlimited

调整线程数

  1. vim /etc/security/limits.d/90-nproc.conf
  2. 找到如下内容：
  3. * soft nproc 1024
  4. #修改为
  5. * soft nproc 4096

ES安装及配置

导入Elasticsearch PGP密钥

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

配置yum

vim /etc/yum.repos.d/elasticsearch.repo

加入以下信息

[elasticsearch]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

安装

# 展示所有版本
sudo yum --showduplicates list elasticsearch
# 安装指定版本
sudo yum install elasticsearch-7.6.2-1

配置开机启动

sudo chkconfig --add elasticsearch

配置

JAVA_HOME

# 编辑配置文件
vim /etc/sysconfig/elasticsearch

# 修改JAVA_HOME的值
JAVA_HOME=/opt/jdk1.8.0_181/

elasticsearch.yml

vim /etc/elasticsearch/elasticsearch.yml

  1. # 集群名称，各个节点的值必须一致
  2. cluster.name: elasticsearch_production
  3. # 节点名称，区分节点，各个节点的值不能一致
  4. node.name: node-1
  6. # 数据文件路径，需要配置datanode所有数据磁盘路径
  7. path.data: 
  8.     - /data/dfs/dfs00/dfs/elasticsearch
  9.     - /data/dfs/dfs01/dfs/elasticsearch
  10.     - /data/dfs/dfs02/dfs/elasticsearch
  12. # 日志文件路径
  13. path.logs: /var/log/elasticsearch
  15. # 设置为true来锁住内存。因为当jvm开始swapping时es的效率会降低，所以要保证它不swap，可以把ES_MIN_MEM和ES_MAX_MEM两个环境变量设置成同一个值，并且保证机器有足够的内存分配给es。同时也要允许elasticsearch的进程可以锁住内存，Linux下可以通过ulimit -l unlimited命令
  16. bootstrap.memory_lock: true
  17. # 因为Centos6不支持SecComp，而ES6.1.2默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动
  18. bootstrap.system_call_filter: false
  19. # 本机IP
  20. network.host: 192.168.1.107
  22. # 集群种子节点

  26.    - 192.168.1.109:9300 
  27. # 集群初始主节点，需要填写node.name中的值
  28. cluster.initial_master_nodes: 
  29.    - node-1
  30.    - node-2
  31.    - node-3
  33. # 存在至少2个节点（数据节点或者 master 节点）才进行数据恢复
  34. gateway.recover_after_nodes: 2
  35. # 等待10分钟，或者3个节点上线后，才进行数据恢复，这取决于哪个条件先达到
  36. gateway.expected_nodes: 3
  37. gateway.recover_after_time: 10m
  39. search.max_buckets: 200000
  40. action.destructive_requires_name: true
