1、上传包到服务器
将下载好的 elasticsearch-7.17.16-linux-x86_64.tar.gz 文件放到 /usr/local/soft 目录下
tar -zxvf elasticsearch-7.17.16-linux-x86_64.tar.gz # 解压
配置环境变量：
vim /etc/profile# 如果/etc/bashrc文件不可编辑，需要修改为可编辑
chmod -v u+w /etc/environment# 在最后一行加上
export ES_JAVA_HOME=/usr/local/soft/elasticsearch-7.17.16/jdksource /etc/environment
注意事项：
-
生效时间：新开终端生效，或者手动
source /etc/environment生效 -
生效期限：永久有效
-
生效范围：对所有用户有效
elasticsearchyml_28">2、修改主配置文件 elasticsearch.yml：
cd /usr/local/soft/elasticsearch-7.17.16vim config/elasticsearch.yml# ES开启远程访问
network.host: 0.0.0.0# 设置主节点（一个集群设一个就行）
node.master: true# 配置发现设置
discovery.seed_hosts: ["127.0.0.1"] # "127.0.0.1"可以改为外网ip
cluster.initial_master_nodes: ["node-1"]# 跨域问题
http.cors.enabled: true
http.cors.allow-origin: "*"# 允许请求头携带密码访问
http.cors.allow-headers: Authorization# 开启密码访问
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
为了方便直接复制下面这一块
network.host: 0.0.0.0
node.name: "node-1"
node.master: true
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: false
discovery.type: single-node
3、修改JVM配置：
修改config/jvm.options配置文件，调整JVM堆内存大小
vim config/jvm.options
-Xms1g
-Xmx1g
- 注意：
启动 elasticsearch 不能使用 root 用户，所以先创建普通用户
sudo useradd -m -s /bin/bash username # 创建sudo passwd username # 设置密码sudo usermod -aG root username # 添加该用户到管理员组# 切换到root用户
chmod -R g+rwx /usr/local/soft/elasticsearch-7.17.16 # 赋予组对该目录及其子目录的读写权
4、启动（切换到创建的用户上启动）：
# 在/usr/local/soft/elasticsearch-7.17.16目录下
bin/elasticsearch# 后台启动
bin/elasticsearch -d
常见启动报错：
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
# 编辑/etc/sysctl.conf文件，在最后添加一行
vim /etc/sysctl.conf
vm.max_map_count=262144# 重启
sudo sysctl -p
设置密码：
执行设置用户名和密码的命令，这里需要为4个用户分别设置密码，elastic, kibana, logstash_system, beats_system
bin/elasticsearch-setup-passwords interactive
[xunlu@xunlu-20231103 elasticsearch]$ bin/elasticsearch-setup-passwords interactive
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.

4、分词插件安装
- IK分词器：Releases · infinilabs/analysis-ik (github.com)
- pinyin分词器：Releases · infinilabs/analysis-pinyin (github.com)
将zip压缩包上传到 plugins 目录
unzip elasticsearch-analysis-ik-7.17.16.zip -d analysis-ik # 解压rm elasticsearch-analysis-ik-7.17.16.zip # 删除压缩包
测试分词：
GET _analyze
{"analyzer": "ik_max_word","text": "原神生日会"
}
