一、windows系统

1.创建角色

进入IAM，点击左侧角色，点击右侧新建角色。如下截图。

从策略界面中，搜索如下两个策略：

• AmazonSSMManagedInstanceCore
• CloudWatchAgentAdminPolicy

注意：每次只能搜索一条。因此搜索一条，选中一条；然后继续搜索另外一条。另外很多策略名字很相似，只有几个字母的差别，请务必仔细选择正确的策略。策略一个字母的差别就无法正常工作。如下截图。

在AWS中国区部署CloudWatch Agent的时候，从中国区S3下载Agent的脚本内容如下：

# Cloudwatch Agent download from China

# 以下为中国区域下载例子，海外区域请替换下载地址

Invoke-WebRequest https://s3.cn-north-1.amazonaws.com.cn/amazoncloudwatch-agent/windows/amd64/latest/amazon-cloudwatch-agent.msi -O C:\Users\Administrator\Downloads\amazon-cloudwatch-agent.msi

# Installation Start-Process C:\Users\Administrator\Downloads\amazon-cloudwatch-agent.msi rm -Force C:\Users\Administrator\Downloads\amazon-cloudwatch-agent.msi

# Download configuration file for Windows Invoke-WebRequest https://blogimg.bitipcman.com/workshop/cloudwatch/cloudwatch-windows-config.json -O 'C:\Program Files\Amazon\AmazonCloudWatchAgent\config.json'

# Start service

# Please keep & in the front of below command

# 如下命令前边的&符号不要去掉，否则无法执行

& "C:\Program Files\Amazon\AmazonCloudWatchAgent\amazon-cloudwatch-agent-ctl.ps1" -a fetch-config -m ec2 -s -c file:"C:\Program Files\Amazon\AmazonCloudWatchAgent\config.json"

# Choco package management

Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

choco install grep -y

# Finally, Restart EC2

# 以上配置不需要重启即可生效，如果改动了本脚本还安装了别的软件可按需重启

# Restart-Computer -Force

如果是海外区域部署，请替换把第一段的下载地址从中国区的：

https://s3.cn-north-1.amazonaws.com.cn/amazoncloudwatch-agent/windows/amd64/latest/amazon-cloudwatch-agent.msi

替换为海外区域的

https://amazoncloudwatch-
agent.s3.amazonaws.com/windows/amd64/latest/amazon-cloudwatch-agent .msi
这样即可在快速完成下载，不会遇到网络问题导致下载失败。
最后按创建按钮，完成EC2创建，

2.打开EC2增强监控

选中EC2，选择更多操作，从下拉框中找到增强监控，并启用之。如下截图。

3.通过Powershell执行命令安装CloudWatch Agent

点击开始菜单，对其中的Powershell点击鼠标右键，选择使用管理员权限打开Powershell。

4.检查CloudWatch数据

二、linux系统 

1.机器和角色（上面不再赘述）

2.安装agent

systemctl status amazon-cloudwatch-agent
yum install -y https://s3.cn-northwest-1.amazonaws.com.cn/amazoncloudwatch-agent-cn-northwest-1/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm
systemctl status amazon-cloudwatch-agent
/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
cd /opt/aws/amazon-cloudwatch-agent/bin/
cp config.json /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json
systemctl start amazon-cloudwatch-agent
systemctl enable amazon-cloudwatch-agent
systemctl status amazon-cloudwatch-agent

3.验证
