CentOS7上安装Node.js

项目需要装Node.js,所有就顺便记录一下

我们这里通过NodeSource安装，我这里安装的是8，直接开始吧.

下载并执行脚本

[root@k46gsv /]# curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -
## Installing the NodeSource Node.js 8.x LTS Carbon repo...

## Inspecting system..
+ rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release
+ uname -m
## Confirming "el7-x86_64" is supported...
+ curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_8.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'
## Downloading release setup RPM...
+ mktemp
+ curl -sL -o '/tmp/tmp.LZzXNGotJM' 'https://rpm.nodesource.com/pub_8.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'
## Installing release setup RPM...
+ rpm -i --nosignature --force '/tmp/tmp.LZzXNGotJM'
## Cleaning up...
+ rm -f '/tmp/tmp.LZzXNGotJM'
## Checking for existing installations...
+ rpm -qa 'node|npm' | grep -v nodesource
## Run `sudo yum install -y nodejs` to install Node.js 8.x LTS Carbon and npm.
## You may also need development tools to build native addons:
 sudo yum install gcc-c++ make
## To install the Yarn package manager, run:
 curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
 sudo yum install yarn

好了，已经提醒让安装nodejs了

Complete!

好了，这就安装完了，我们来测试一下：

node版本：

[root@k4622v /]# node --version
v8.11.3

npm版本：

[root@k4622v /]# npm --version
5.6.0

另外就是上面安装的时候提醒需要安装开发工具库，我们这里也安装一下：

yum install gcc-c++ make -y

好了，到此结束
