1. linux 安裝 nodejs

进入安装目录或资源目录

[root@server-test-211 ~]# cd /home/app/software/

下載node包

更多版本从这里获取 https://nodejs.org/dist/

[root@server-test-211 ~]# wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz

解压

[root@server-test-211 ~]# tar -xvf node-v8.11.3-linux-x64.tar.xz

移动到node目录（重命名）

[root@server-test-211 ~]# mv node-v8.11.3 nodejs

建立全局软链接

[root@server-test-211 ~]# sudo ln -s /home/kz/software/nodejs/bin/npm /usr/local/bin/npm
[root@server-test-211 ~]# sudo ln -s /home/kz/software/nodejs/bin/node /usr/local/bin/node

检测是否已安装

[root@server-test-211 ~]# node -v

[root@server-test-211 ~]# npm -v

删除软链

删除软链之前最好先把nodejs包删除

[root@server-test-211 ~]# rm -rf  /usr/local/bin/npm
[root@server-test-211 ~]# rm -rf  /usr/local/bin/node

安装 cnpm

执行指令：

[root@server-test-211 ~]# npm install -g cnpm --registry=https://registry.npm.taobao.org

结果：

[root@server-test-211 ~]# npm install -g cnpm --registry=https://registry.npm.taobao.org
/home/kz/software/nodejs/bin/cnpm -> /home/kz/software/nodejs/lib/node_modules/cnpm/bin/cnpm
+ cnpm@6.0.0
added 679 packages from 899 contributors in 12.415s

设置全局软连：

[root@server-test-211 ~]# ln -s /home/kz/software/nodejs/bin/cnpm /usr/local/bin/cnpm

验证：

[root@server-test-211 ~]# cnpm -v
