centos7.7环境安装elasticsearch7.5.1集群
作者：互联网
centos7.6系统的elasticsearch7.5.1集群部署
整体策略：
将集群配置好，并且通过命令 curl 10.10.17.19:9200/_cluster/health?pretty 检查状态为green
然后再次修改配置文件启用xpack认证，并拷贝认证文件到各节点，重启集群的节点
1.配置新版本的elasticsearch使用自带的openjdk13
# vim bin/profile
export JAVA_HOME=/usr/local/elk/elasticsearch-7.5.1/jdk
export PATH=$JAVA_HOME/bin:$PATH
# 创建相关的日志和数据目录
mkdir -p /data/es/data
mkdir -p /data/es/logs
mkdir -p /data/esback
groupadd -g 1500 elasticsearch
useradd -u 1500 -g elasticsearch elasticsearch
swapoff -a
echo "fs.file-max = 1000000" >> /etc/sysctl.conf
echo "vm.max_map_count=262144" >> /etc/sysctl.conf
echo "vm.swappiness = 1" >> /etc/sysctl.conf
sysctl -p
sed -i 's/* soft nofile 65535/* soft nofile 655350/g' /etc/security/limits.conf
sed -i 's/* hard nofile 65535/* hard nofile 655350/g' /etc/security/limits.conf
sed -i 's#* soft nproc 4096##' /etc/security/limits.d/20-nproc.conf
chown -R elasticsearch.elasticsearch /data/es
chown -R elasticsearch.elasticsearch /data/esback
chown -R elasticsearch.elasticsearch /usr/local/elk/elasticsearch-7.5.1
