无法安装awslogs代理

Question

我在尝试在ec2节点上安装awslogs代理时遇到问题.当我运行此命令时:

sudo python ./awslogs-agent-setup.py --region us-east-1

它似乎在第2步失败了:

Launching interactive setup of CloudWatch Logs agent ... 

Step 1 of 5: Installing pip ...DONE

Step 2 of 5: Downloading the latest CloudWatch Logs agent bits ... 
Traceback (most recent call last):
  File "./awslogs-agent-setup.py", line 1144, in <module>

  File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

缺少什么目录或文件？

Answer 1

我通过传递要使用的python解释器解决了这个问题：

sudo python ./awslogs-agent-setup.py --region us-east-1 --python=/usr/bin/python3.5

Answer 2

亚马逊 Linux 2

awslogs 代理现在作为 yum 包提供https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/QuickStartEC2Instance.html

sudo yum install -y awslogs
sudo systemctl start awslogsd
sudo systemctl enable awslogsd.service

确保更改文档中提到的 AWS 区域

Answer 3

虽然这个问题有点老了，但我想添加一个答案，因为我最近遇到了同样的问题，但设法找到了解决方法。我试图在运行 CentOS 7 的实例中安装它。

当我第一次运行安装命令时，我得到了与@user2061886报告的完全相同的错误日志。安装程序会记录到具有以下路径的文件：/var/log/awslogs-agent-setup.log。我跟踪该文件并发现安装程序在内部抱怨无法找到文件“Python.h”：

    checking if libyaml is compilable
    gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-

    error: command 'gcc' failed with exit status 1

我无法让它与 Python 2.7 一起工作，所以我切换到了 Python 3.5。要在 CentOS 7 中安装 Python 3.5：

yum -y udpate

yum install -y epel-release

yum install -y http://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64/ius-
release-1.0-13.ius.centos7.noarch.rpm

yum -y update

yum install -y python35u*

我再次运行安装程序命令并通过了@user2061886 报告的错误。我可以安装和配置 CloudWatch Logs Agent。然而，在我启动服务（sudo service awslogs start）后不久，我遇到了第二个问题。这次我必须跟踪以下文件才能发现问题：/var/log/awslogs.log。cloudwatch 日志代理基本上抱怨无法找到 cwlogs 包：

Traceback (most recent call last):
  File "/var/awslogs/bin/aws", line 27, in <module>
    sys.exit(main())
  File "/var/awslogs/bin/aws", line 23, in main
    return awscli.clidriver.main()
  File "/usr/lib/python3.5/site-packages/awscli/clidriver.py", line 55, in main
    driver = create_clidriver()
  File "/usr/lib/python3.5/site-packages/awscli/clidriver.py", line 64, in create_clidriver
    event_hooks=emitter)
  File "/usr/lib/python3.5/site-packages/awscli/plugin.py", line 44, in load_plugins
    modules = _import_plugins(plugin_mapping)
  File "/usr/lib/python3.5/site-packages/awscli/plugin.py", line 58, in _import_plugins
    plugins.append(__import__(path))
ImportError: No module named 'cwlogs'

我通过使用 pip 手动安装包解决了这个问题：

pip3.5 install awscli-cwlogs. 

这样问题就解决了！
