無法在AWS EC2上設置回送生產主機

Question

我在AWS EC2上設置StrongLoop LoopBack生產主機時遇到問題。 我正在遵循這些指示 。

這就是我嘗試過的。 我創建了一個EC2服務器，它是Ubuntu Server 14.04 LTS。 然后我：

$ 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.

如您所見，我無法將獨立的StrongLoop Process Manager模塊安裝為“ ubuntu”或使用“ sudo”。 這讓我想知道是否應該以root用戶身份安裝所有內容，但是我也遇到了這種方法的麻煩：

$ 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

嘗試以根用戶身份安裝獨立的StrongLoop Process Manager模塊時，出現以下錯誤：

# npm install -g strong-pm

在AWS EC2上設置StrongLoop LoopBack生產主機的正確方法是什么？ 怎么樣了

Answer 1

您可以使用此博客文章中記錄的以下命令從PPA安裝NodeJS：

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

評論中建議的其他想法也有潛力。 但是，這是我能夠輕松進行的工作。
