我在 VM (ubuntu) 上配置了 Prometheus、node-exporter 和 alertmanager 以下视频：https ://www.youtube.com/watch?v=7gW5pSM6dlU
Prometheus 和 node-exporter 工作正常，但我无法启动 alertmanager。
user1@ubuntu1:/usr/local/bin/alertmanager$ sudo service alertmanager start
user1@ubuntu1:/usr/local/bin/alertmanager$ sudo service alertmanager status
● alertmanager.service - Prometheus Alert Manager
Loaded: loaded (/etc/systemd/system/alertmanager.service; disabled; vendor preset: enabled)

但是 amtool 成功检查了我的配置文件：
user1@ubuntu1:/usr/local/bin/alertmanager$ ./amtool check-config ./alertmanager.yml
Checking './alertmanager.yml' SUCCESS
Found:
- global config
- route
- 1 inhibit rules
- 1 receivers
- 0 templates
我的 alertmanager 配置文件如下所示：
global:
resolve_timeout: 5m
route:
group_by: [Alertname]
group_interval: 30s
repeat_interval: 30s
# Send all notifications to me.
receiver: email-me
receivers:
- name: email-me
email_configs:
- send_resolved: true
to: my_real_email@gmail.com
from: my_real_email@gmail.com
smarthost: smtp.gamil.com:587
auth_username: my_real_email@gmail.com
auth_identity: my_real_email@gmail.com
auth_password: 'my_password'
inhibit_rules:
- source_match:
severity: 'critical'
target_match:
severity: 'warning'
equal: ['alertname', 'dev', 'instance']
我的服务看起来像这样：
[Unit]
Description=Prometheus Alert Manager
After=network.targer
[Service]
Type=simple
ExecStart=/usr/local/bin/alertmanager --config.file=/usr/local/bin/alertmanager/alertmanager.yml
[Install]
WantedBy=multi-user.target
我不知道为什么它显示“权限被拒绝”，因为我用 sudo 开始服务。有任何想法吗？
