【TiDB Environment】Production
【TiDB Version】v6.1.1
【Encountered Issue】

Error: init config failed: x.x.x.x:9090:add local rule: read local directory /data1/tidbcluster/tidb-deploy/prometheus-8249/prometheus_rule failed: open /data1/tidbcluster/tidb-deploy/prometheus-8249/prometheus_rule: no such file or directory

Do I need to manually create the directory /data1/tidbcluster/tidb-deploy/prometheus-8249/prometheus_rule?

Here is my monitoring-related configuration

monitoring_servers:
  - host: x.x.x.x
    ssh_port: 22
    port: 9090
    ng_port: 12020
    deploy_dir: "/data1/tidbcluster/tidb-deploy/prometheus-8249"
    log_dir:    "/data1/tidbcluster/tidb-deploy/prometheus-8249/log"
    rule_dir:   "/data1/tidbcluster/tidb-deploy/prometheus-8249/prometheus_rule"
    data_dir:   "/data1/tidbcluster/tidb-data/prometheus-8249"

grafana_servers:
  - host: x.x.x.x
    port: 3000
    deploy_dir: "/data1/tidbcluster/tidb-deploy/grafana-3000"
    dashboard_dir: "/data1/tidbcluster/tidb-deploy/grafana-3000/dashboards"
    config:
       log.file.level: warning

alertmanager_servers:
  - host: x.x.x.x
    ssh_port: 22
    listen_host: 0.0.0.0
    web_port: 9093
    cluster_port: 9094
    deploy_dir: "/data1/tidbcluster/tidb-deploy/alertmanager-9093"
    log_dir:    "/data1/tidbcluster/tidb-deploy/alertmanager-9093/log"

  1. What is the user in the YAML configuration file?
  2. The /data1 directory must exist, and the user in the configuration file must be the owner and group of /data1. If the owner of /data1 cannot be changed, then manually create the tidbcluster directory and change its owner and group to the user in the configuration file.

  1. The user in the YAML configuration file is TIDB, and passwordless login has been configured. Permissions and other settings are also normal.
  2. The /data1 directory exists, and the user in the configuration file is the owner and group owner of /data1, which is also the TIDB user.

  1. What about directory permissions? Are they writable and executable?
  2. There are two types of “password-free” as mentioned above:
    1. Each node’s tidb user can use password-free sudo to the root user of that node;
    2. The tidb user on the control machine can log in to the tidb users on all other nodes without a password.

The problem has been solved by using the default simplest monitoring configuration.
