单台主机下安装Agent

操作场景

本章节主要介绍如何在单台主机中手动安装Agent，为用户提供主机的系统级、主动式、细颗粒度的监控服务。

约束与限制

目前只支持Linux操作系统和Windows操作系统。支持的系统请参见Agent支持的系统有哪些？。

前提条件

• 已配置DNS和安全组，配置方法参考如何配置DNS和安全组？。
• 已配置委托，配置方法参考如何配置委托？。
• 确保操作步骤中的安装目录都有读写权限，安装用户为root，并且安装成功后的Telescope进程不会被其他软件关闭。
• 确保已下载Agent安装脚本，获取脚本的方式如下：

操作步骤

1. 使用root账号，登录主机。
2. 执行以下命令，安装Agent，安装脚本分为agent_install.sh和agentInstall.sh，分别对应以下两种命令。

   新架构Agent：cd /usr/local && curl -k -O ${download_url} && bash agent_install.sh -t ${version} -u {uniagentVersion} -r {regionID}

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

   将${download_url} 替换成表1中的下载路径，将${version}替换成Agent版本特性中的版本。例如，用北京一下载地址替换${download_url}，对应的安装命令为：

   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

   命令执行完成时，输出Telescope process starts successfully.则代表安装成功。

3. 执行如下命令，清除安装脚本。

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

Agent插件配置完成后，因监控数据暂未上报，插件状态仍显示“未安装”，等待3-5分钟，刷新即可。
