需求方直接甩手给我一个需求, 考虑之下, 采用了 node 来作为后端 koa + mongodb 真香
首先是在宝塔上安装 mongodb
将监听 ip 设置为 0.0.0.0 (不考虑 authorization)
然后写一个测试登录的文件
const mongodb = require('mongoose')
const { env: config } = require('./config')
require('colors')
const db = mongodb.connect(config.db, {
useUnifiedTopology: true,
useNewUrlParser: true
}).then(r=> {
console.log(`${ 'debug'.green }: MongoDB connected success❤️`.blue)
}).catch(r=> {
throw new Error(`${ 'debug'.red }: MongoDB connected fail😂`.red)
})
这个 mongoose 玩法还真是不同, 共享一个实例
代码写好了, 就到了部署到线上去, 开开心心的登录 ssh 打开宝塔后台安装 pm2, 发现怎么都启动不了服务, 查看日志看到了

我们遇到什么困难都不要怕, 微笑着面对它, 消除的error的唯一办法就是 google...
查了很多文档, 一开始我的解决办法是手动安装 pm2
➜ ~ node -v zsh: command not found: node
WTF, 没有安装 nodejs
➜ ~ sudo cat /etc/redhat-release CentOS release 6.10 (Final)
手动安装还是报错, 猜测可能是 gcc 版本过低(这不是废话吗)
下载操作一下, 由于下载是在是太慢了, 就在下载过程中, 尝试了很多操作..
wget ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-4.9.2/gcc-4.9.2.tar.bz2
由于是线上环境, 不太敢乱动
