我在VM(ubuntu(上配置了Prometheus、节点导出器和alertmanager，如下所示：https://www.youtube.com/watch?v=7gW5pSM6dlU
普罗米修斯和节点导出器运行良好，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成功地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：
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']
我的服务是这样的：
[Unit]

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"；"许可被拒绝"；，因为我用sudo开始服务。有什么想法吗？
好的，我再次设置了VM、Prometheus和Alertmanager，现在服务开始了，没有任何问题。
权限被拒绝错误，因此尝试在altermanager.service文件中添加用户和组
