1.安装elasticsearch
useradd elasticsearch passwd elasticsearch tar zxf elasticsearch-7.12.1-linux-x86_64.tar.gz -C /home/elasticsearch/ chown -R elasticsearch:elasticsearch /home/elasticsearch/
2.修改配置文件和JVM参数
vim /home/elasticsearch/elasticsearch-7.12.1/config/elasticsearch.yml # 集群名称，集群内所有节点的名称必须一致 cluster.name: my-es # 当前节点是否用于主节点 node.master: true # 当前节点是否用于数据节点 node.data: true # 索引数据存放的位置 path.data: /home/elasticsearch/elasticsearch-7.12.1/data # 日志文件存放的位置 path.logs: /home/elasticsearch/elasticsearch-7.12.1/logs # 集群内部节点名必须唯一且在集群内部可以解析 node.name: node-1 # 绑定监听ip network.host: 0.0.0.0 # es对外提供的http端口，默认 9200 http.port: 9200 # es内部通信端口，默认 9300 #transport.tcp.port: 9300 # 集群节点地址 discovery.seed_hosts: ["node-1", "node-2", "node-3"] # 参与选举的主节点 cluster.initial_master_nodes: ["node-1", "node-2", "node-3"] # 开启跨域访问 不安全 # http.cors.enabled: true # http.cors.allow-origin: "*" vim /home/elasticsearch/elasticsearch-7.12.1/config/jvm.options # 根据实际情况修改 -Xms4g # 最小堆大小 -Xmx4g # 最大堆大小
3.修改内核参数
cat >> /etc/sysctl.conf << EOF vm.max_map_count=262144 EOF sysctl -p
4.修改资源限制
cat >> /etc/security/limits.conf << EOF * soft nofile 1024000 * hard nofile 1024000 * soft nproc 1024000 * hard nproc 1024000 EOF
5.启动和停止elasticsearch
su -c "/home/elasticsearch/elasticsearch-7.12.1/bin/elasticsearch -d" elasticsearch
jps | grep -i elasticsearch | awk ‘{print $1}‘ | xargs kill
ps -ef | grep elasticsearch | grep -v grep | awk ‘{print $2}‘ | xargs kill
6.安装ElasticSearch Head插件
# 插件源码托管：https://github.com/mobz/elasticsearch-head
# 此处只介绍作为服务安装在服务器上
6.1.安装nodeJS
cd /usr/local wget https://nodejs.org/dist/v14.17.0/node-v14.17.0-linux-x64.tar.xz tar Jxf node-v14.17.0-linux-x64.tar.xz ln -s node-v14.17.0-linux-x64 node cat >> /etc/profile << EOF export NODE_HOME=/usr/local/node export PATH=\$PATH:\$NODE_HOME/bin EOF source /etc/profile
6.2.安装elasticsearch-head
cd /usr/local git clone git://github.com/mobz/elasticsearch-head.git cd elasticsearch-head npm config set registry https://registry.npm.taobao.org npm install --ignore-scripts
6.3.允许跨域访问
# 配置文件已定义 此步骤忽略
cat >> /home/elasticsearch-7.12.1/config/elasticsearch.yml << EOF http.cors.enabled: true http.cors.allow-origin: "*"
6.4.重启es并启动elasticsearch-head
ps -ef | grep elasticsearch | grep -v grep | awk ‘{print $2}‘ | xargs kill
su -c "/home/elasticsearch/elasticsearch-7.12.1/bin/elasticsearch -d" elasticsearch
cd /usr/local/elasticsearch-head && npm run start &
