Deploy HertzBeat Server​

  1. Execute the following command
$ docker run -d -p 1157:1157 -p 1158:1158 \
    -v $(pwd)/data:/opt/hertzbeat/data \
    -v $(pwd)/logs:/opt/hertzbeat/logs \
    -v $(pwd)/application.yml:/opt/hertzbeat/config/application.yml \
    -v $(pwd)/sureness.yml:/opt/hertzbeat/config/sureness.yml \
    --restart=always \
    --name hertzbeat apache/hertzbeat

Command parameter explanation

  • docker run -d : Run a container in the background via Docker
  • -p 1157:1157 -p 1158:1158 : Mapping container ports to the host, 1157 is web-ui port, 1158 is cluster port.
  • -v $(pwd)/data:/opt/hertzbeat/data : (optional, data persistence) Important, Mount the H2 database file to the local host, to ensure that the data is not lost due creating or deleting container.
  • -v $(pwd)/logs:/opt/hertzbeat/logs : (optional) Mount the log file to the local host to facilitate viewing.
  • -v $(pwd)/application.yml:/opt/hertzbeat/config/application.yml : (optional) Mount the configuration file to the container (please ensure that the file exists locally). Download
  • -v $(pwd)/sureness.yml:/opt/hertzbeat/config/sureness.yml : (optional) Mount the account configuration file to the container (please ensure that the file exists locally). Download

tip
  • Marked as optional parameters, non-mandatory items, if not needed, delete them.
  • This maps the 1157,1158 ports of the container to the 1157,1158 ports of the host. If the port on the host is already occupied, you need to modify the host mapping port.
  • When mounting files, the first parameter is your custom local file address, and the second parameter is the container file address. Make sure you have this file locally when mounting.
  • You can execute docker update --restart=always hertzbeat to configure the container to restart automatically.
  • If you want to use the host network mode to start Docker, you can use docker run -d --network host .....

    -e MANAGER_PORT=1158 \
    --name hertzbeat-collector apache/hertzbeat-collector

Command parameter explanation

  • docker run -d : Run a container in the background via Docker
  • -e IDENTITY=custom-collector-name : (optional) Set the collector unique identity name. Attention the clusters collector name must unique.
  • -e MODE=public : set the running mode(public or private), public cluster or private
  • -e MANAGER_HOST=127.0.0.1 : Important, Set the main hertzbeat server ip host, must use the server host instead of 127.0.0.1.
  • -e MANAGER_PORT=1158 : (optional) Set the main hertzbeat server port, default 1158.
  • -v $(pwd)/logs:/opt/hertzbeat-collector/logs : (optional) Mount the log file to the local host to facilitate viewing.
  • --name hertzbeat-collector : Naming container name hertzbeat-collector

FAQ​

The most common problem is network problems, please check in advance

  1. MYSQL, TDENGINE, IoTDB and HertzBeat are deployed on the same host by Docker,HertzBeat use localhost or 127.0.0.1 connect to the database but fail
    The problems lies in Docker container failed to visit and connect localhost port. Because the docker default network mode is Bridge mode which can't access local machine through localhost.

    Solution A：Configure application.yml. Change database connection address from localhost to external IP of the host machine.
    Solution B：Use the Host network mode to start Docker, namely making Docker container and hosting share network. docker run -d --network host .....

  2. According to the process deploy，visit http://ip:1157/ no interface
    Please refer to the following points to troubleshoot issues：

    1：If you switch to dependency service MYSQL database，check whether the database is created and started successfully. 2：Check whether dependent services, IP account and password configuration is correct in HertzBeat's configuration file application.yml. 3：docker logs hertzbeat Check whether the container log has errors. If you haven't solved the issue, report it to the communication group or community.

  3. Historical monitoring charts have been missing data for a long time

    1：Check whether you configure victoria-metrics or Tdengine or IoTDB. No configuration means no historical chart data. 2: Check whether IP account and password configuration is correct in HertzBeat's configuration file application.yml.

  4. If the history chart on the monitoring page is not displayed，popup [please configure time series database]

    As shown in the popup window，the premise of history chart display is that you need install and configure hertzbeat's dependency service database. Installation and initialization this database, please refer to Using victoria-metrics to store metrics data

  5. The time series database is installed and configured, but the page still displays a pop-up [Unable to provide historical chart data, please configure dependent time series database]

    Please check if the configuration parameters are correct Is time-series database enable set to true Note⚠️If both hertzbeat and time-series database are started under the same host for docker containers, 127.0.0.1 cannot be used for communication between containers by default, and the host IP is changed You can check the startup logs according to the logs directory

  6. What is the purpose of application.yml

This file is the configuration file of HertzBeat, used to configure various parameters of HertzBeat, such as database connection information, time series database configuration, etc. Download application.yml file to the host directory, for example: $(pwd)/application.yml Download source github/script/application.yml
You can modify the configuration yml file according to your needs.

  • If you need to use email to send alarms, you need to replace the email server parameters spring.mail in application.yml
  • Recommended If you need to use an external Mysql database to replace the built-in H2 database, you need to replace the spring.datasource parameter in application.yml For specific steps, see Using Mysql to replace H2 database
  • Recommended If you need to use the time series database victoria-metrics to store metric data, you need to replace the warehouse.store.victoria-metrics parameter in application.yml for specific steps, see Using victoria-metrics to store metrics data
  1. What is the purpose of sureness.yml

This file is the user configuration file of HertzBeat, used to configure user information of HertzBeat, such as account password, etc. HertzBeat default built-in three user accounts, respectively admin/hertzbeat tom/hertzbeat guest/hertzbeat If you need update account or password, configure sureness.yml. Ignore this step without this demand. Download and config sureness.yml in the host directory，eg:$(pwd)/sureness.yml Download from github/script/sureness.yml For detail steps, please refer to Configure Account Password
