Linux 服务器
CentOS Linux release 7.3.1611 (Core)
配置node环境
查看node是否安装
[root@localhost ~]# node
bash: node: 未找到命令...
从以上命令看出,node环境没有安装,需要安装node基础环境
首先去node官网下载node的安装包
英文官网访问太慢可以访问中文官网
阿里云镜像：https://npm.taobao.org/mirrors/node/
本次下载的node版本是：node-v6.11.3-linux-x64.tar.xz
解压
# 解压
[root@localhost ~]# tar -xvf node-v6.11.3-linux-x64.tar.xz
[root@localhost ~]# mv node-v6.11.3-linux-x64 /usr/local/node
## 配置环境变量
[root@localhost ~]# vim /etc/profile
[root@localhost ~]# node
配置环境变量
[root@localhost ~]# vim /etc/profile
export NODE_HOME=/usr/local/node
export PATH=$NODE_HOME/bin:$PATH
[root@localhost local]# source /etc/profile
[root@localhost local]# node -v
v6.11.3
部署
该项目是依赖nuxt开发,参考文章：nuxt commands章节
官网说明中可以在项目中的package.json文件中查看
package.json配置文件如下：

最终后台启动
[root@localhost ~] npm run start &
> off@1.0.0 start /mnt/lishi/website
> nuxt start
OPEN http://iZbp10yas4kb5a9dudjbw2Z:18010
其他
node程序最终启动成功,可以通过ps命令查找进程
[root@localhost ~] ps -ef|grep node
lishi 10155 10145 0 11:19 pts/1 00:00:03 node /mnt/project/website/node_modules/.bin/nuxt start
root 13134 10274 0 13:43 pts/1 00:00:00 grep --color=auto node
[root@localhost ~]
通过端口查找：
[root@localhost ~] netstat -anp|grep 8083
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:8083 0.0.0.0:* LISTEN 27562/java
[root@localhost ~] netstat -anp|grep 18010
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:18010 0.0.0.0:* LISTEN 10155/node
lishi@iZbp10yas4kb5a9dudjbw2Z:/usr/local/nginx/conf/vhost>
通过上面列出来的进程信息,18010端口是node开启的服务器,8083是后台Java开启的tomcat服务
比较之后，会发现一个是127.0.0.1，一个是0.0.0.0
重点说明 0.0.0.0 是对外开放，通过服务域名、ip可以访问的端口
127.0.0.1 只能对本机 localhost访问，也是保护此端口安全性
所以最终node启用的服务 最后我只能改由nginx代理才能出去，这个怎么解决尚未有解决方案
pm2
pm2 是一个带有负载均衡功能的Node应用的进程管理器.当你要把你的独立代码利用全部的服务器上的所有CPU,并保证进程永远都活着,0秒的重载, PM2是完美的
PM2是node进程管理工具，可以利用它来简化很多node应用管理的繁琐任务，如性能监控、自动重启、负载均衡等，而且使用非常简单。

nuxt.js的项目启动命令，先执行npm run build,在执行npm run start,pm2也支持参数的传递，也有大神说pm2启动nuxt只需要执行pm2 start npm -- run start,到目前为止，表示项目没有这样启动成功过。
所以我们要知道package.json这个文件，当我们执行npm run dev的时候，其实使用npm去启动了./node_modules/nuxt/bin/nuxt这个文件。当我们cd到我们的项目目录之后，我们最终可以执行如下命令来启动：
pm2 start ./node_modules/nuxt/bin/nuxt -- start
以上命令启动是默认端口3000，如果我们要自定义端口 需要执行参数
