以编程方式安装 composer 在 vagrant 上工作但不在 EC2 实例上工作

Question

我正在研究 Ansible 剧本。在 vagrant 机器上配置时，一切顺利，没有错误。现在我在以编程方式安装 composer 的步骤上遇到了麻烦。

安装-composer.sh（此脚本取自Composer Page）

#!/bin/sh

EXPECTED_SIGNATURE="$(wget -q -O - https://composer.github.io/installer.sig)"
echo $EXPECTED_SIGNATURE;
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_SIGNATURE="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"
echo $ACTUAL_SIGNATURE; <- Here is empty!

if [ "$EXPECTED_SIGNATURE" != "$ACTUAL_SIGNATURE" ]
then
    >&2 echo 'ERROR: Invalid installer signature'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --quiet
RESULT=$?
rm composer-setup.php
exit $RESULT

EC2 是一个 Ubuntu 16.04 实例，也是在 vagrant 上。

我遇到错误的 Playbook 任务：

 - name: Download Composer
      script: scripts/install_composer.sh
      register: composer_setup
      #when: not composer_stat.stat.exists
      tags:
        - deploy

以及 --verbose:

知道为什么此行在 ec2 上返回空吗？

"$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

谢谢！

Answer 1

我的第一个猜测是您的 EC2 实例无法访问互联网。你能证实这一点吗？详细日志表明 composer-setup.php 文件在您尝试对其进行哈希处理时不存在。您应该尝试使用当前的 copy() 方法下载该文件，然后执行以下操作：

TESTSTUFF="$(php -r "echo file_exists('composer-setup.php') ? 'FILE EXISTS' : 'FILE DOES NOT EXIST';")"
echo $TESTSTUFF

如果文件不存在，请尝试从某处下载不同的文件，such as a dummy test file from here。

所有迹象都表明文件不存在，这可能是由一系列问题引起的。但是，最有可能的是：

EC2 上无法访问互联网（您能 ping 通 8.8.8.8 吗？）
执行权限不当php
写入目标文件系统的权限不正确

Answer 2

在尝试了 Aaron 所说的之后，我发现 php 没有正确安装（根本没有安装）

我正在执行：

ansible-playbook ansible/playbook.yml -i ansible/hosts.ini -t deploy --ask-vault-pass --verbose

注意标签 deploy，所以这里假设安装了 php。所要做的就是从我的命令中删除 -t deploy！
