Question

我正在尝试在Ubuntu 12.04上使用nginx运行乘客Web服务器的安装，使用Ansible 1.4.1似乎gem安装正在搞乱或者其他什么，因为ansible找不到命令，并且我手动重新安装宝石它的工作原理。我做错了什么？

# ruby.yml

- name: "install ruby"
  script: scripts/install_ruby.sh

- name: "Install bundler"
  gem: name=bundler state=latest

- name: "Install passenger"
  gem: name=passenger state=latest

- name: "Copy nginx upstart"
  copy: src=nginx.conf dest=/etc/init/nginx.conf mode=0644 owner=root group=root

- name: Install passenger-nginx
  command: passenger-install-nginx-module --auto-download --auto --prefix=/opt/nginx --extra-configure-flags='--with-http_gzip_static_module --with-http_secure_link_module --with-http_realip_module --with-http_ssl_module' creates=/opt/nginx

- name: "Enable Nginx"
  service: name=nginx state=started enabled=yes

错误：

FATAL: all hosts have already failed -- aborting

当我进去时，我看到宝石存在：

root @ staging-2：〜＃gem list

*** LOCAL GEMS ***

bigdecimal (1.2.3)
bundler (1.5.2)
daemon_controller (1.1.8)
io-console (0.4.2)
json (1.8.1)
minitest (4.7.5)
passenger (4.0.36)
psych (2.0.2)
rack (1.5.2)
rake (10.1.0)
rdoc (4.1.0)
test-unit (2.1.0.0)

但是，当我尝试运行install命令时，它仍然无效：

root@staging-2:~# passenger-install-nginx-module
passenger-install-nginx-module: command not found

只有在我重新运行时它才有效：

gem install passenger

Ruby是从源代码安装的，这里是我的gem env

root@staging-2:~# gem env
RubyGems Environment:

我看到GEM PATH目录中存在可执行文件：

- /root/.gem/ruby/2.1.0

但显然这没有被添加到主路径中？

Ansible的gem模块可以在幕后使用--user-install option吗？

好的，显然是：http://docs.ansible.com/gem_module.html#gem-manage-ruby-gems

留下问题以供其他人参考

Answer 1

由于您使用的是Ubuntu，只需使用Ansible通过apt-get安装the Phusion Passenger Debian packages（点击“Ubuntu”）。它与apt-getting其他任何东西完全相同，比使用RubyGems安装要容易得多，甚至为你安装所有必需的依赖项（包括Ruby本身！）

Answer 2

中断，因为Ansible现在默认使用user_install选项进行gem安装，从Ansible 1.3开始

http://docs.ansible.com/gem_module.html#gem-manage-ruby-gems

--user-install option

如何从Ansible安装passenger-nginx？
