9. Check that the Grafana interface is loading correctly. In your browser, navigate to the URL of the server where Grafana is installed, on port 3000 (for example, http://example.com:3000).

   • 请确保防火墙已开放 3000 端口，以顺利访问 Grafana

1. Install the grafana package:

   zypper in grafana

2. 启用 Grafana 服务：

   systemctl enable --now grafana-server

3. In your browser, navigate to the URL of the server where Grafana is installed, on port 3000 (for example, http://example.com:3000).

   • 请确保防火墙已开放 3000 端口，以顺利访问 Grafana。

7. 应用 Highstate 并确认它成功完成。

1. 在 SUSE Multi-Linux Manager 容器主机的命令行中，以 root 身份运行以下命令：

   1. 运行以下命令生成证书文件。

      Ensure that the set-cname parameter is the fully qualified domain name (FQDN) of your Salt client. You can use the set-cname parameter multiple times if you require multiple aliases:

      mgrctl exec -ti -- mgr-ssl-tool --gen-server --dir="/root/ssl-build" --set-country="COUNTRY" \
        --set-state="STATE" --set-city="CITY" --set-org="ORGANIZATION" \
        --set-org-unit="ORGANIZATION UNIT" --set-email="name@example.com" \
        --set-hostname="minion.example.com" --set-cname="minion.example.com" --no-rpm

      命令执行的结果：

      Generating the web server's SSL private key: /root/ssl-build/minion/server.key
      Generating web server's SSL certificate request: /root/ssl-build/minion/server.csr
      Generating/signing web server's SSL certificate: server.crt

   2. Copy server.crt and server.key files from the server container to the host:

      mgrctl cp server:/root/ssl-build/minion/server.key server.key
      mgrctl cp server:/root/ssl-build/minion/server.crt server.crt

   3. Copy server.crt and server.key files from the host to the monitoring client:

      ssh minion.example.com 'mkdir /etc/ssl/mlm-server-certs'
      scp /root/server.* minion.example.com:/etc/ssl/mlm-server-certs
      ssh minion.example.com 'chmod go+r /etc/ssl/mlm-server-certs/server.*; ls -la /etc/ssl/mlm-server-certs'

2. 要配置 Salt 公式，请输入之前的步骤中指定的目录名称。

   1. formular server

      Server Certificate /etc/ssl/mlm-server-certs/server.crt
      Server Key /etc/ssl/mlm-server-certs/server.key
