ElasticSearch6.5.2安装说明

Posted 2022-05-07 datacat

#1新增用户es
useradd es
passwd es

#2调整系统参数
vi /etc/hosts
#ES_Cluster
192.168.0.51 ESNode1
192.168.0.52 ESNode2
192.168.0.53 ESNode3

修改机器名
vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=ESNode1

#执行命令
# hostname ESNode1

CentOS7要多执行以下这步：
hostnamectl set-hostname ESNode1

#配置系统最大打开文件描述符数
vi /etc/sysctl.conf
vm.max_map_count = 262144

#执行以下命令生效
sysctl -p

配置进程最大打开文件描述符
vim /etc/security/limits.conf           //文件最后

* soft nofile 65536
* hard nofile 65536

#3上传elasticsearch-6.5.2.rpm并安装
rpm -ivh elasticsearch-6.5.2.rpm


#4编写ES Master节点配置文件
[root@esnode1 es]# vi /etc/elasticsearch/elasticsearch.yml
