在 AWS EC2 上设置 Loopback 生产主机时遇到问题

Question

我在 AWS EC2 上设置 StrongLoop LoopBack 生产主机时遇到问题。我正在关注 these directions。

这是我试过的。我创建了一个 Ubuntu Server 14.04 LTS 的 EC2 服务器。那我:

$ ssh -i ~/mykey.pem ubuntu@[ec2-ip-address]
$ sudo apt-get update
$ sudo apt-get install build-essential
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh | bash
$ nvm install v0.12.4
$ nvm alias default 0.12.4
$ npm install -g strong-pm

$ sudo sl-pm-install
sudo: sl-pm-install: command not found

$ sl-pm-install
Error adding user strong-pm:
useradd: Permission denied.
useradd: cannot lock /etc/passwd; try again later.
Error installing service 'undefined': Command failed: /usr/sbin/useradd --home /var/lib/strong-pm --shell /bin/false --skel /dev/null --create-home --user-group --system strong-pm
useradd: Permission denied.
useradd: cannot lock /etc/passwd; try again later.

如您所见，我无法将独立的 StrongLoop Process Manager 模块安装为 "ubuntu" 或使用 "sudo." 这让我想知道我是否应该以 root 身份安装所有内容，但我运行也遇到了这种方法的麻烦：

$ sudo su
# curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh | bash
# nvm install v0.12.4
# nvm alias default 0.12.4

当尝试以 root 身份安装独立的 StrongLoop Process Manager 模块时，出现以下错误：

# npm install -g strong-pm
> heapdump@0.3.5 install /root/.nvm/versions/node/v0.12.4/lib/node_modules/strong-pm/node_modules/strong-runner/node_modules/strong-supervisor/node_modules/heapdump

在 AWS EC2 上设置 StrongLoop LoopBack 生产主机的正确方法是什么？怎么做到的？

Answer 1

您可以使用 this blog post 中记录的以下命令从 PPA 安装 NodeJS：

$ curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
$ sudo apt-get install -y nodejs

评论中提出的其他想法也有潜力。然而，这是我能够轻松开始工作的那个。
