在CentOS使用宝塔使用pm2部署node的express项目

超、凢脫俗 2023-10-06 16:18 26阅读 0赞

宝塔按钮pm2后，node就装好了。

对于前端开发人员来说，配置后端服务器的工作都是脑瓜疼的，好在宝塔这种可视化工具还是挺好用

在部署上线前，假设你的项目已经写好的了。

## 1. 在宝塔上添加新的站点 ##

## 2. 打包你的项目到站点目录下(我的放在根目录下) ##

## 3. 安装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是开源的基于Nodejs的进程管理器，包括守护进程，监控，日志的一整套完整的功能，基本是Nodejs应用程序不二的守护进程选择，事实上它并不仅仅可以启动Nodejs的程序，只要是一般的脚本的程序它同样可以胜任。

主要特性：

内建负载均衡（使用Node cluster 集群模块）  
后台运行  
0秒停机重载（这项功能允许你重新载入代码而不用失去请求连接。）  
具有Ubuntu和CentOS 的启动脚本  
停止不稳定的进程（避免无限循环）  
控制台检测  
提供 HTTP API  
远程控制和实时的接口API ( Nodejs 模块,允许和PM2进程管理器交互 )

## 4.点击设置打开pm2配置环境 ##

### 4.1选择node的版本跟安装依赖 ###

## 5.配置nginx（因为我的宝塔安装的是Nginx） ##

在nginx站点配置文件下添加(后面的端口号是node设置的那个)

location / {
        
    	proxy_pass http://127.0.0.1:3033;
     }
