Procedure

1. Log in to an ECS as user root.
2. Run either of the commands below to install the Agent. agent_install.sh and agentInstall.sh are the installation scripts.

   Agent of the new architecture:

   cd /usr/local && curl -k -O ${download_url} && bash agent_install.sh -t ${version} -r ${regionID}

   Agent of the earlier architecture:

   cd /usr/local && curl -k -O ${download_url} && bash agentInstall.sh

   

   In Table 1, the Agent in the CN South-Guangzhou-InvitationOnly, LA-Sao Paulo1, and LA-Mexico City1 regions is using the earlier architecture. The Agent in other regions is using the new architecture.

   Replace ${download_url} with the download path in Table 1, ${version} with the actual Agent version in Agent Features per Version, and ${regionID} with the region ID in Table 1. For example, replace ${download_url} with the download path of CN North-Beijing1. The corresponding installation command is as follows:

   cd /usr/local && curl -k -O https://obs.cn-north-1.myhuaweicloud.com/uniagent-cn-north-1/package/agent_install.sh && bash agent_install.sh -t 2.5.6 -r cn-north-1

   If Telescope process starts successfully. is displayed after the command is executed, the installation is successful.

3. Run the following command to clear the installation script:

   if [[ -f /usr/local/uniagent/extension/install/telescope/bin/telescope ]]; then rm /usr/local/agent_install.sh; else rm /usr/local/agentInstall.sh; fi

After you configure the Agent, its status is still displayed as Uninstalled because the monitoring data is not reported yet. Wait 3 to 5 minutes and refresh the page.
