启动es（集群各机器）

复制代码

systemctl start elasticsearch

防火墙放行

复制代码

firewall-cmd --zone=public --add-port=9200/tcp --permanent&&firewall-cmd --reload
firewall-cmd --zone=public --add-port=9300/tcp --permanent&&firewall-cmd --reload

生成证书（其中1台机器）

复制代码

cd /data/elasticsearch/elasticsearch-6.8.11
./bin/elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass ""

#修改属主
chown elastic:elastic elastic-certificates.p12

拷贝证书到其余节点相同目录

复制代码

#修改属主
chown elastic:elastic elastic-certificates.p12

执行命令生成密码

复制代码

/data/elasticsearch/elasticsearch-6.8.11/bin/elasticsearch-setup-passwords interactive

重启es(所有节点)

复制代码

systemctl stop elasticsearch
systemctl start elasticsearch
