ruby-on-rails - 服务器重启后 Puma 不启动

Question

我用 capistrano 部署了项目，但是服务器重启后 puma 没有启动..

我应该做 -> cap production puma:start every time

我试过了:

/etc/init.d/myscript

#!/bin/sh
/etc/init.d/puma_start.sh

puma_start.sh

#!/bin/bash 
puma -C /root/project/shared/puma.rb

但是，我有错误

/usr/local/rvm/rubies/ruby-2.3.3/lib/ruby/site_ruby/2.3.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem puma (>= 0.a) (Gem::GemNotFoundException)
    from /usr/local/rvm/rubies/ruby-2.3.3/lib/ruby/site_ruby/2.3.0/rubygems.rb:298:in `activate_bin_path'
    from /usr/local/rvm/gems/ruby-2.3.3@project/bin/puma:22:in `<main>'
    from /usr/local/rvm/gems/ruby-2.3.3@project/bin/ruby_executable_hooks:15:in `eval'
    from /usr/local/rvm/gems/ruby-2.3.3@project/bin/ruby_executable_hooks:15:in `<main>'

如果我在控制台中输入 root@host:~# puma -C/root/project/shared/puma.rb 它可以工作，一切正常。

我想我没有正确的 gem puma 路径

服务器重启后如何让puma自动启动

从 Ubuntu 16.04 开始推荐使用 systemctl。在我使用 Upstart 之前。我为自己创建了这个指令。也许对某人有用。
