2.2 安装 CloudWatch 代理软件包
## 安装 CloudWatch 代理软件包
# 系统更新
$ sudo yum update -y
# 安装代理包
$ sudo yum install -y amazon-cloudwatch-agent
# 安装collectd
$ sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
$ sudo yum install -y collectd
2.3 使用 CloudWatch代理收集指标
## 使用 CloudWatch代理收集指标
- 建立代理配置文件
- 启动CloudWatch代理
# 设置代理
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard
# 启动代理
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl \
-a fetch-config -m ec2 -s \
-c file:/opt/aws/amazon-cloudwatch-agent/bin/config.json
# 代理启动进程确认
$ ps aux | grep agent
[ec2-user@ip-172-16-1-18 ~]$ cat /opt/aws/amazon-cloudwatch-agent/bin/config.json
