¶Mariadb 的 Docker 在每次寫入會 Aborted connection

¶執行環境

node.js + express
pm2
docker

¶出錯描述

送出寫入資料庫，就出現錯誤

¶錯誤訊息:

Aborted connection 12 to db

¶解決方案

在 ecosystem.config.js 加這行

ignore_watch: ['node_modules', 'db'],

整個檔案

module.exports = {
  /**
   * Application configuration section
   * http://pm2.keymetrics.io/docs/usage/application-declaration/
   */
  apps: [
    {
      name: "backend-system-API",
      script: "bin/www",
      max_restarts: 1,
      autorestart: false,
      watch: true,
      ignore_watch: ["node_modules", "db"],
      env: {
        NODE_PATH: "."
      }
    }
  ]
};

¶根本原因

db 資料夾，在 INSERT 時會自動更新
所以 pm2 就自動啟動了，造成出錯。

設定 pm2 忽略 watch 資料夾

• node_modules,
• db
