[英]Not able to run my node app at port 80 on ubuntu 16.04
I want to run my node app at port 80 in ubuntu 16.04. 我想在ubuntu 16.04的80端口运行我的节点应用程序。 But the moment I'm trying to run my app with
npm start
its throwing error Port in already in use whereas it's not in use. 但是,当我尝试使用
npm start
运行我的应用npm start
它的抛出错误Port已在使用中 ,而未在使用中。 According to Github Reply , We need root privileges to run on ports below 1048 which is correct. 根据Github回复 ,我们需要root特权才能在1048以下的端口上运行,这是正确的。 So the moment I'm trying to run my app like this
sudo npm install
it's throwing sudo: npm: command not found 因此,当我尝试像
sudo npm install
这样运行我的应用sudo npm install
它会抛出sudo:npm:命令未找到
So can anyone suggest me, how to run npm start
with root privileges on ubuntu. 所以有人可以建议我,如何在ubuntu上以root特权运行
npm start
。 I did googling but couldn't find anything. 我做了谷歌搜索,但找不到任何东西。
First run which npm
to get the full path to npm. 首先运行
which npm
以获得which npm
的完整路径。
Then run sudo FULL_PATH_TO_NPM start
. 然后运行
sudo FULL_PATH_TO_NPM start
。
Or to make a one-liner: 或制作单线:
sudo $(which npm) start
Both sudo and npm(including node) should be same directory. sudo和npm(包括节点)应位于同一目录。 For example sudo is always available in
/usr/bin/
so after installing npm and node should also go in /usr/bin/
. 例如,sudo始终在
/usr/bin/
可用,因此在安装npm后,node也应该在/usr/bin/
。 earlier I was using NVM to install node and npm. 之前,我使用NVM安装node和npm。 I removed
.nvm
directory and referred node installation link which placed both npm and node in /usr/bin/
. 我删除了
.nvm
目录,并引用了节点安装链接 ,该链接将npm和node都放置在/usr/bin/
。 And then now I'm able to run npm with sudo. 然后,我现在可以使用sudo运行npm了。
