这适用于 ubuntu 16.04，但不适用于 17.10

我注意到在此过程的早期，在 AWS 样板中它未能安装 libyaml-dev 但不确定这是否是唯一的问题。

总能在我发布后立即找到答案...

这是我修改后的 CF 模板命令：

    050_install_awslogs:
      command: !Sub 
        "/bin/bash -x\n
        exec >>/var/log/cf_050_install_awslogs.log 2>&1 \n
        echo 050_install_awslogs...\n
        set -xe\n
        # Get the CloudWatch Logs agent\n
        mkdir /opt/awslogs\n
        cd /opt/awslogs\n
        # Needed for python3 in 17.10\n
        apt-get install -y libyaml-dev python-dev \n
        pip3 install awscli-cwlogs\n
        # avoid it complaining about not having /var/awslogs/bin/aws binary\n
        if [ ! -d /var/awslogs/bin ] ; then\n
          mkdir -p /var/awslogs/bin\n
          ln -s /usr/local/bin/aws /var/awslogs/bin/aws\n
        fi\n
        curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O\n
        chmod +x ./awslogs-agent-setup.py\n
        # Hack for python 3.6 & old awslogs-agent-setup.py\n
        sed -i 's/3,6/3,7/' awslogs-agent-setup.py\n
        ./awslogs-agent-setup.py -n -c /etc/awslogs/awslogs.conf -r ${AWS::Region}\n
        echo 050_install_awslogs end\n
        "

不完全确定是否需要创建目录，但我希望这是一个临时案例，很快就会得到解决，因为仍然需要捏造 python 3.6 兼容性检查。

它也可以使用 python 2.7 安装，但此时感觉就像倒退了，因为我对 17.10 的基本原理是 python 3.6。

将 yaml 包和目录创建想法归功于https://forums.aws.amazon.com/thread.jspa?threadID=265977，但我更愿意避免使用 easy_install。

我在 Ubuntu 18.04 上遇到了类似的问题。

AWS的独立安装说明适用于我的案例。

To download and run it standalone, use the following commands and follow the prompts:

curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O
curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/AgentDependencies.tar.gz -O
tar xvf AgentDependencies.tar.gz -C /tmp/
sudo python ./awslogs-agent-setup.py --region us-east-1 --dependency-path /tmp/AgentDependencies
