Centos7.9+ElasticSearch8.3.2安装步骤

本文介绍在Centos7.9上安装ElasticSearch8.3.2的详细步骤。
安装环境：
操作系统：Centos7.9
ElasticSearch版本：8.3.2
ElasticSearch 的安装用户：es
ElasticSearch 的安装目录: /u01

1.创建数据库安装用户

# groupadd es
# useradd -g es es
# passwd es
复制

2.操作系统设置

2.1 修改用户资源限制

# vi /etc/security/limits.conf
es - nofile 65536
es - memlock unlimited
复制

2.2 修改操作系统参数

# vi /etc/sysctl.conf 
vm.max_map_count=262144
复制

3.解压ElasticSearch，并修改文件权限

# tar -zxf elasticsearch-8.3.2-linux-x86_64.tar.gz 
# ll
total 526668
drwxr-xr-x 9 root root       155 Jul  6 23:22 elasticsearch-8.3.2
-rw-r--r-- 1 root root 539306119 Jul 15 17:07 elasticsearch-8.3.2-linux-x86_64.tar.gz
# mv /u01/soft/elasticsearch-8.3.2 /u01/es8.3.2
# chown -R es: /u01/es8.3.2/
复制

4.设置环境变量

# su - es
$ vi .bashrc
--添加下面两行
export ES_HOME=/u01/es8.3.2
export PATH=/u01/es8.3.2/bin:$PATH
$ . .bashrc
复制

5.修改数据库配置文件

vi /u01/es8.3.2/config/elasticsearch.yml
文件尾追加如下几行：
# 指定集群名称
cluster.name: es-application
# 指定节点名称
node.name: node-1
# 设置允许访问的IP地址
network.host: 0.0.0.0
# 设置ElasticSearch 端口号
http.port: 9200
# 设置数据目录
path.data: /u01/es8.3.2/data
# 设置日志目录
path.logs: /u01/es8.3.2/logs
# 设置备份存储目录
path.repo: /u01/backup
复制

6. 设置java进程内存大小

vi /u01/es8.3.2/config/jvm.options
修改下面两行：
## -Xms4g
## -Xmx4g
根据实际系统情况进行调整：
-Xms1g
-Xmx1g
复制

7.启动ElasticSearch

-- 启动命令
$ elasticsearch -d
