Filebeat连接到backoff失败?

Question

我有2台服务器A和b。当我在服务器A上运行docker-compose时，它工作得很好。但是在服务器B上我有以下错误:

pipeline/output.go:154  Failed to connect to backoff(async(tcp://logstash_ip:5044)): dial tcp logstash_ip:5044: connect: no route to host

所以我想我错过了服务器b上的一些配置，所以我怎么才能找出我的问题并解决它们。

[编辑]添加filebeat.yml和docker-compose

注意:我在服务器A上运行filebeat失败了，所以我在服务器B上测试了它，它仍然可以工作。所以我想我有一些问题与服务器配置

1. filebeat.yml

logging.level: error
logging.to_files: true
logging.files:
path: /var/log/filebeat
name: filebeat
keepfiles: 7
permissions: 0644
filebeat.inputs:
- type: log
enabled: true
paths:
- /usr/share/filebeat/mylog/**/*.log
processors:
- decode_json_fields:
fields: ['message']
target: 'json'
output.logstash:
hosts: ['logstash_ip:5044']
console.pretty: true
processors:
- add_docker_metadata:
host: 'unix:///host_docker/docker.sock'

2. docker-compose

version: '3.3'
services:
filebeat:
user: root
container_name: filebeat
image: docker.elastic.co/beats/filebeat:7.9.3
volumes:
- /var/run/docker.sock:/host_docker/docker.sock
- /var/lib/docker:/host_docker/var/lib/docker
- ./logs/progress:/usr/share/filebeat/mylog
- ./filebeat.yml:/usr/share/filebeat/filebeat.yml:z
command: ['--strict.perms=false']
ulimits:
memlock:
soft: -1
hard: -1
stdin_open: true
tty: true
network_mode: bridge
deploy:
mode: global
logging:
driver: 'json-file'
options:
max-size: '10m'
max-file: '50'

Thanks in advance

Answer 1

假设:

• 上述docker-compose文件是用于filebeat "集中"服务器
• 两个服务器运行在同一个网络空间和/或它们之间是可访问的
• 服务器B作为filebeat服务器有正确的防火墙设置来接受端口5044的连接(在启动容器后从服务器A进行telnet检查)

docker-compose(假设服务器B)

version: '3.3'
services:
filebeat:
user: root
container_name: filebeat
ports:             ##################
- 5044:5044      # <- see open port
image: docker.elastic.co/beats/filebeat:7.9.3
volumes:
- /var/run/docker.sock:/host_docker/docker.sock
- /var/lib/docker:/host_docker/var/lib/docker
- ./logs/progress:/usr/share/filebeat/mylog
- ./filebeat.yml:/usr/share/filebeat/filebeat.yml:z
command: ['--strict.perms=false']
ulimits:
memlock:
soft: -1
hard: -1
stdin_open: true
tty: true
network_mode: bridge
deploy:
mode: global
logging:
driver: 'json-file'
options:
max-size: '10m'
max-file: '50'

filebeat.yml(假设两个服务器)

logging.level: error
logging.to_files: true
logging.files:
path: /var/log/filebeat
name: filebeat
keepfiles: 7
permissions: 0644
filebeat.inputs:
- type: log

paths:
- /usr/share/filebeat/mylog/**/*.log
processors:
- decode_json_fields:
fields: ['message']
target: 'json'
output.logstash:
hosts: ['<SERVER-B-IP>:5044']  ## <- see server IP
console.pretty: true
processors:
- add_docker_metadata:
host: 'unix:///host_docker/docker.sock'
