两台centos7.9服务器
master：47.94.214.196
node：59.110.222.6
部署OS
1、安装部署centos 7
2、设置IP
3、修改hostname、hosts文件
hosts文件中加入两个主机节点的IP与主机名映射：
# 修改hosts文件 vim /etc/hosts # 添加 47.94.214.196 elas-A 59.110.222.6 elas-B
4、修改系统配置文件
vim /etc/sysctl.conf # 在/etc/sysctl.conf中添加 vm.max_map_count=655360
5、在/etc/security/limits.conf中添加
vim /etc/security/limits.conf # 以下内容添加到末行 * soft nofile 655350 * hard nofile 655350 * soft nproc 102400 * soft memlock unlimited * hard memlock unlimited1、下载jdk17
#在 /ope 目录下安装jdk cd /opt wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz tar -zxvf jdk-17_linux-x64_bin.tar.gz # 将jdk-17改名为java mv jdk-17 java1.1添加环境变量
# 进入profile文件，按i进入编辑模式 vim /etc/profile # 在文件最下方添加 export JAVA_HOME=/opt/java export PATH=$PATH:$JAVA_HOME/bin; export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar; # 按下Esc退出编辑模式 # 下一步按住shift 再按俩次 z 键，保存配置文件信息 # 重新加载环境变量 source /etc/profile # 查看jdk版本 java -version2、下载elasticsearch，本项目使用的是7.15.1。
切换非root用户下载解压，本项目使用的是www用户
su www cd /home/www/ mkdir els cd els # 下载 elasticsearch-7.15.1 wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.15.1-linux-x86_64.tar.gz # 解压elasticsearch-7.15.1 tar -zxvf elasticsearch-7.15.1-linux-x86_64.tar.gz2.1部署master节点
更改elasticsearch.yml配置文件，该文件在本项目位于
vim /home/www/els/elasticsearch-7.15.1/config/elasticsearch.yml2.3在elasticsearch.yml最下方添加
http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: false bootstrap.system_call_filter: false ##集群名称，每个节点配置成一样的名称才能形成正确的集群 cluster.name: gfb ###节点名称，每个节点配置不同名称 node.name: master ###是否主节点 node.master: true ###集群主节点node名称 cluster.initial_master_nodes: ["master"] ###是否数据节点 node.data: true ###单机最大节点数 node.max_local_storage_nodes: 1 ###索引数据的存储路径 path.data: /home/www/elasticsearch/elasticsearch-7.15.1/date ###日志文件的存储路径 path.logs: /home/www/elasticsearch/elasticsearch-7.15.1/log ###绑定的ip地址，外网也可以访问 network.host: 0.0.0.0 ###设置对外服务的http端口，默认为9200 http.port: 9200 ### 设置节点间交互的tcp端口 transport.tcp.port: 9300 transport.tcp.compress: true ### 设置集群中节点的初始列表，可以通过这些节点来自动发现新加入集群的节点 discovery.zen.ping.unicast.hosts: ["47.94.214.196:9300","59.110.222.6:9300"] discovery.zen.minimum_master_nodes: 1 ###防止同一个shard的主副本存在同一个物理机上 cluster.routing.allocation.same_shard.host: true
根据注释更改所需内容
2.4启动elasticsearch# -d为后台启动 ./home/www/elasticsearch/elasticsearch-7.15.1/bin/elasticsearch -d报错：
因elasticsearch所占内存较多，启动时可能会遇到内存不足报错
解决方法：
# 修改elasticsearch安装目录下的config里的jvm.options vim /home/www/elasticsearch/elasticsearch-7.15.1/config/jvm.options
在最下方添加jvm.options
# 把每个elasticsearch都修改为340m 让它们平均分配虚拟机的内存，当然你也可以增大自己的虚拟机内存 -Xms340m -Xmx340m再次启动elasticsearch
启动后web端访问 master公网IP:9200查看启动状态
3、部署node节点复制master节点的jdk包和elasticsearch包至node节点相同目录
步骤与master一致
3.1、重点：修改elasticsearch.yml配置文件
node.name
network.host
以下为我本项目node节点配置
http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: false bootstrap.system_call_filter: false ##集群名称，每个节点配置成一样的名称才能形成正确的集群 cluster.name: gfb ####节点名称，每个节点配置不同名称 node.name: node1 ####是否主节点 node.master: false ####集群主节点node名称 cluster.initial_master_nodes: ["master"] ####是否数据节点 node.data: true ####单机最大节点数 node.max_local_storage_nodes: 1 ####索引数据的存储路径 path.data: /home/www/elasticsearch/elasticsearch-7.15.1/date ####日志文件的存储路径 path.logs: /home/www/elasticsearch/elasticsearch-7.15.1/log ####绑定的ip地址，外网也可以访问 network.host: 0.0.0.0 ####设置对外服务的http端口，默认为9200 http.port: 9200 #### 设置节点间交互的tcp端口 transport.tcp.port: 9300 transport.tcp.compress: true #### 设置集群中节点的初始列表，可以通过这些节点来自动发现新加入集群的节点 discovery.zen.ping.unicast.hosts: ["47.94.214.196:9300","59.110.222.6:9300"] discovery.zen.minimum_master_nodes: 1 ####防止同一个shard的主副本存在同一个物理机上 cluster.routing.allocation.same_shard.host: true3.2、node节点后台启动elasticsearch
# -d为后台启动 ./home/www/elasticsearch/elasticsearch-7.15.1/bin/elasticsearch -d
此时我遇到报错提示vm.max_map_count [65530]过小，但实际上已经更改了。
[www@elas-B bin]$ ./elasticsearch -d [www@elas-B bin]$ WARNING: A terminally deprecated method in java.lang.System has been called WARNING: System::setSecurityManager has been called by org.elasticsearch.bootstrap.Elasticsearch (file:/home/www/els/elasticsearch-7.15.1/lib/elasticsearch-7.15.1.jar) WARNING: Please consider reporting this to the maintainers of org.elasticsearch.bootstrap.Elasticsearch WARNING: System::setSecurityManager will be removed in a future release WARNING: A terminally deprecated method in java.lang.System has been called WARNING: System::setSecurityManager has been called by org.elasticsearch.bootstrap.Security (file:/home/www/els/elasticsearch-7.15.1/lib/elasticsearch-7.15.1.jar) WARNING: Please consider reporting this to the maintainers of org.elasticsearch.bootstrap.Security WARNING: System::setSecurityManager will be removed in a future release ERROR: [1] bootstrap checks failed.

reboot重启后解决，再次执行./elasticsearch -d启动成功

Edge或Chrome浏览器，安装Elasticvue扩展。下载链接：https://elasticvue.com
安装完扩展后，可通过浏览器的elasticvue扩展程序查看elasticsearch的运行状态，并可测试REST API。
完结撒花~
