对phper来说，接触java相关的配置都需要好好记录下来。 因为项目需求，现在要自己搭建es环境 java环境请先自行安装，这里主要讲es安装 安装前，es首页默认时最新版，比如我现在默认最新是8.0.0 。 重要！重要！重要！请先根据自己操作系统选择支持的版本 ：【链接：】 支持矩阵 | Elastic 选择版本：【链接：】Elasticsearch Guide | Elastic 进入下载页： 这里有每一种操作系统的完整安装引导 8.0的linux链接：Install Elasticsearch from archive on Linux or MacOS | Elasticsearch Guide [8.0] | Elastic 二、按照文档进行安装elasticSearch这里分两种形式安装，一种是tar.gz包安装，一种是rpm安装 （一）rpm安装1.按照官方的命令安装es 执行命令： wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.17.1-x86_64.rpm wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.17.1-x86_64.rpm.sha512 yum install perl-Digest-SHA shasum -a 512 -c elasticsearch-7.17.1-x86_64.rpm.sha512 sudo rpm --install elasticsearch-7.17.1-x86_64.rpm 复制代码2.修改配置文件 /etc/elasticsearch/elasticsearch.yml [root@localhost opt]# vim /etc/elasticsearch/elasticsearch.yml [root@localhost opt]# grep -Ev "^#" /etc/elasticsearch/elasticsearch.yml cluster.name: forpastime node.name: node-249 path.data: /data/elasticsearch path.logs: /data/log/elasticsearch bootstrap.memory_lock: true network.host: 192.168.2.249 http.port: 9200 discovery.seed_hosts: ["192.168.2.249"] cluster.initial_master_nodes: ["node-249"] 复制代码查看修配置文件生效的命令：grep -Ev "^#" /etc/elasticsearch/elasticsearch.yml 3.因为我们指定了es数据和日志存储目录，所以添加目录 [root@localhost /]# mkdir data [root@localhost /]# mkdir data/log [root@localhost /]# mkdir data/elasticsearch [root@localhost /]# mkdir data/log/elasticsearch 复制代码4.安装后默认添加了elasticsearch用户，所以将新增的目录权限给elasticsearch [root@localhost /]# chown -R elasticsearch:elasticsearch /data/elasticsearch [root@localhost /]# chown -R elasticsearch:elasticsearch /data/log/elasticsearch 复制代码5.修改/etc/elasticsearch/jvm.options文件 [root@localhost log]# vim /etc/elasticsearch/jvm.options 增加如下代码 -Xms512m -Xmx512m 复制代码如果此时启动es，会无法成功，查看日志： tail -n 1000 /data/log/elasticsearch/elasticsearch.log 或其他日志文件 复制代码遇到memory is not locked，需要作如下6的操作： 6.执行systemctl edit elasticsearch，输入以下内容 [root@localhost log]# systemctl edit elasticsearch 输入： [Service] LimitMEMLOCK=infinity 复制代码Ctrl + O提示是否写入，Enter回车 Ctrl + X 7.启动es，查看启动状态和端口情况 [root@localhost log]# systemctl daemon-reload [root@localhost log]# systemctl start elasticsearch.service [root@localhost log]# systemctl status elasticsearch ● elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: disabled) Drop-In: /etc/systemd/system/elasticsearch.service.d └─override.conf Active: active (running) since 三 2022-03-02 11:09:27 CST; 12s ago Docs: https://www.elastic.co Main PID: 19592 (java) Tasks: 69 CGroup: /system.slice/elasticsearch.service ├─19592 /usr/share/elasticsearch/jdk/bin/java -Xshare:auto -Des.networkaddress.cache.ttl=60 -Des.networkaddress.cache.negative.ttl=10 └─19796 /usr/share/elasticsearch/modules/x-pack-ml/platform/linux-x86_64/bin/controller 3月 02 11:09:18 localhost.localdomain systemd[1]: Starting Elasticsearch... 3月 02 11:09:27 localhost.localdomain systemd[1]: Started Elasticsearch.
