How to run rails s -p80 on 80 port?
提问by mlzboy
By default,
默认情况下，
rails s #running on 3000 port
Now I want to run it on port 80. So I tried:
现在我想在端口 80 上运行它。所以我尝试了：
sudo rails -s -p80
But it threw an error:
但它抛出了一个错误：
mlzboy@mlzboy-MacBook ~/my/b2c2 $ sudo rails s -p80
sudo: rails: command not found
I used rvm to install ruby & rails. It seems rvm is user specified. Is it not able to find rails in root?
我使用 rvm 来安装 ruby 和 rails。看来 rvm 是用户指定的。是不是无法在 root 中找到 rails？
I also tried below code:
我也试过下面的代码：
mlzboy@mlzboy-MacBook ~/my/b2c2 $ which rails
/home/mlzboy/.rvm/gems/ruby-1.9.2-p0/bin/rails
mlzboy@mlzboy-MacBook ~/my/b2c2 $ sudo /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/bin/rails s -p80

rvmsudo rails server -p 80

Just forward the request from port 80 to 3000 using below command:
只需使用以下命令将请求从端口 80 转发到 3000：
sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 3000
Another option is:
另一种选择是：
rvmsudo rails server -p 80
However please remember to free this port from Apache or other services which consume this port normally. Also, I m not sure giving sudo permission to RVM may have any security issue or not?
但是请记住从 Apache 或其他正常使用此端口的服务中释放此端口。另外，我不确定授予 RVM sudo 权限是否有任何安全问题？

Was going to suggest
本来打算建议
rails=`which rails` ; sudo $rails server -p 80
but that still tries to use the global gemset and not the project gemset from RVM. So...
但这仍然尝试使用全局 gemset 而不是来自 RVM 的项目 gemset。所以...
- Make sure sshd is running on your Mac. (System Prefs => Sharing => Remote Login checked)
- Make sure
rails sis running on port 3000 as your non-root user Open a new terminal and...
me=``whoami``; sudo ssh -L 80:127.0.0.1:3000 -l $me -N localhost
- 确保 sshd 在您的 Mac 上运行。（系统偏好设置 => 共享 => 远程登录已选中）
- 确保
rails s以非 root 用户身份在端口 3000 上运行 打开一个新终端，然后...
me=``whoami``; sudo ssh -L 80:127.0.0.1:3000 -l $me -N localhost
(BTW reduce the duplicate `'s to singular ones in the line above, I cannot figure out how escape it properly here.)
（顺便说一句，在上面的行中将重复的 `'s 减少为单数，我不知道如何在这里正确地转义它。）
The first Password:is your rootuser, the second is the password for whomever whoamireturns.
第一个Password:是您的root用户，第二个是whoami返回者的密码。
Though you probably want to install Phusion Passenger and set it up under your local Apache. Unless you are just trying to demo something real quick and this is not a permanent solution of course.
尽管您可能想要安装 Phusion Passenger 并将其设置在您本地的 Apache 下。除非你只是想快速演示一些东西，这当然不是一个永久的解决方案。

If you are using RVM, and you did the default setup, then you shouldn't use sudo.
如果您使用的是 RVM，并且进行了默认设置，则不应使用sudo.
Just:
只是：
mlzboy@mlzboy-MacBook ~/my/b2c2 $ rails server -p 80
However 80 is a privileged port, so you needto run as root, and you will have follow the instructions for Multi-User installationof RVM.
回答by uma
you can start server on port 80
您可以在端口 80 上启动服务器
rails s -p 80
If port 80 does not bind(other processes is not using to port 80).
如果端口 80 未绑定（其他进程未使用端口 80）。
