Logstash 输出到 Elasticsearch SSL 证书
我有以下 docker 容器
docker create \
--name=elasticsearch \
--restart=always \
--network=infrastructure_network \
--network-alias=elasticsearch \
-e TZ=Etc/UTC \
-e discovery.type=single-node \
-e "ES_JAVA_OPTS=-Xms6g -Xmx6g" \
-e ELASTIC_PASSWORD="foobar" \
-p 9200:9200 \
-p 9300:9300 \
-v elasticsearch:/usr/share/elasticsearch \
elasticsearch:8.0.0
docker create \
--name=logstash \
--restart=always \
--network=infrastructure_network \
--network-alias=logstash \
-e TZ=Etc/UTC \
-p 5040:5040 \
-p 8514:8514/udp \
-v logstash:/usr/share/logstash/ \
-v elasticsearch:/elastic/ \
logstash:8.0.0
容器启动得很好,但是..当我将logstash 输出设置如下时:
input
{
tcp
{
port => 8514
type => syslog
}
}
filter
{
if [type] == "syslog"
{
grok
{
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
add_field => [ "received_at", "%{@timestamp}" ]
add_field => [ "received_from", "%{host}" ]
}
date
{
match => [ "syslog_timestamp", "MMM d HH:mm:ss.SSS", "MMM dd HH:mm:ss.SSS" ]
timezone => "UTC"
}
}
}
output
{
elasticsearch
{
hosts => ['https://elasticsearch:9200']
cacert => '/elastic/config/certs/http_ca.crt'
ssl_certificate_verification => false
user => "elastic"
password => "foobar"
index => "syslog"
ilm_enabled => false
}
stdout { codec => rubydebug }
}
我在logstash 日志中收到以下错误...
引起的:sun.security.validator.ValidatorException:PKIX 路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径
[2022-03-02T03:27:04,496] [警告][logstash.outputs.elasticsearch][main] 尝试恢复与失效 ES 实例的连接,但出现错误 {:url=>"https://elastic:xxxxxx@elasticsearch:9200/", :exception=> LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError,:message=>“Elasticsearch 无法访问: [https://elasticsearch:9200/][Manticore::ClientProtocolException] PKIX 路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径”}
[2022-03-02T03:27 :08,344][DEBUG][logstash.outputs.elasticsearch][main] 等待连接到 Elasticsearch 集群,正在重试在 16 秒后,
我假设我使用了错误的证书?这是当 elascticsearch 容器启动时创建的证书,我应该使用什么?
I have the following docker containers
docker create \
--name=elasticsearch \
--restart=always \
--network=infrastructure_network \
--network-alias=elasticsearch \
-e TZ=Etc/UTC \
-e discovery.type=single-node \
-e "ES_JAVA_OPTS=-Xms6g -Xmx6g" \
-e ELASTIC_PASSWORD="foobar" \
-p 9200:9200 \
-p 9300:9300 \
-v elasticsearch:/usr/share/elasticsearch \
elasticsearch:8.0.0
docker create \
--name=logstash \
--restart=always \
--network=infrastructure_network \
--network-alias=logstash \
-e TZ=Etc/UTC \
-p 5040:5040 \
-p 8514:8514/udp \
-v logstash:/usr/share/logstash/ \
-v elasticsearch:/elastic/ \
logstash:8.0.0
The containers start perfectly fine, but.. when I set the logstash output as follows:
input
{
tcp
{
port => 8514
type => syslog
}
}
filter
{
if [type] == "syslog"
{
grok
{
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
add_field => [ "received_at", "%{@timestamp}" ]
add_field => [ "received_from", "%{host}" ]
}
date
{
match => [ "syslog_timestamp", "MMM d HH:mm:ss.SSS", "MMM dd HH:mm:ss.SSS" ]
timezone => "UTC"
}
}
}
output
{
elasticsearch
{
hosts => ['https://elasticsearch:9200']
cacert => '/elastic/config/certs/http_ca.crt'
ssl_certificate_verification => false
user => "elastic"
password => "foobar"
index => "syslog"
ilm_enabled => false
}
stdout { codec => rubydebug }
}
I get the following error in the logstash logs...
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
[2022-03-02T03:27:04,496][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"https://elastic:xxxxxx@elasticsearch:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :message=>"Elasticsearch Unreachable: [https://elasticsearch:9200/][Manticore::ClientProtocolException] PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"}
[2022-03-02T03:27:08,344][DEBUG][logstash.outputs.elasticsearch][main] Waiting for connectivity to Elasticsearch cluster, retrying in 16s
I'm assuming that I'm using the wrong cert maybe? It's the cert that is created when the elascticsearch container is spun up, what SHOULD I be using ??

确保您在
cacert
中指向的文件包含弹性端使用的证书的完整链(我们让它首先与 root 一起使用,然后按顺序与任何中间 CA 一起使用)Make sure the file you point to in
cacert
contains the full chain of the certificate used on the elastic side (we've had it work with root first and then any intermediate CAs in order)添加 ssl => true 输出弹性
add
ssl => true
to output elastic
