Installing the Agent
This section describes how to install the Agent for an existing BMS. The procedure is as follows:
- Adding the Resolved Domain Names: Add the resolved domain names of regions to the /etc/resolv.conf file on the BMS.
- Configuring the Security Group: Download the Telescope package, send metrics, and collect logs.
- Installing the Agent: Manually install the Agent on the BMS.
Adding the Resolved Domain Names
- Log in to the BMS as user root.
- Enter vi /etc/resolv.conf to open the /etc/resolv.conf file.
- Add nameserver 100.125.1.250 and nameserver 100.125.21.250 to the file, as shown in Figure 1.
The values of nameserver vary depending on the region.
CN North-Beijing1: 100.125.1.250 and 100.125.21.250
CN North-Beijing4: 100.125.1.250 and 100.125.129.250
CN East-Shanghai1: 100.125.1.250,100.125.64.250
CN South-Guangzhou: 100.125.1.250 and 100.125.136.29
