生成证书

#1.生成CA证书
# 生成CA证书,执行命令后,系统还会提示你输入密码,可以直接留空
cd /usr/share/elasticsearch/bin
./elasticsearch-certutil ca
 
#会在/usr/share/elasticsearch/下生成一个elastic-stack-ca.p12文件
ls -l /usr/share/elasticsearch/
-rw-------. 1 elastic elastic 2527 May 21 14:29 elastic-stack-ca.p12
 
#2.根据elastic-stack-ca.p12文件 生成elastic-certificates.p12
# 生成证书和私钥,系统还会提示你输入密码，你可以输入证书和密钥的密码，也可以留空
cd /usr/share/elasticsearch/
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12

把生成的证书放到 /etc/elasticsearch/目录下，并授权

不加认证，启动集群模式

egrep -v “#|^$” /etc/elasticsearch/elasticsearch.yml

cluster.name: es
node.name: es1
path.data: /app/es/data

启动集群，查看状态

curl -XGET  "http://127.0.0.1:9200/_cat/nodes"

添加认证和证书，重启集群

egrep -v “#|^$” /etc/elasticsearch/elasticsearch.yml

cluster.name: es

设置口令

./bin/elasticsearch-setup-passwords interactive

查看集群信息

curl -XGET -u elastic:123456 "http://127.0.0.1:9200/_cluster/health?pretty"
curl -XGET -u elastic:123456 "http://127.0.0.1:9200/_cat/nodes"
