PM2:在一台服务器上部署多个环境？

Question

我使用 PM2 进行部署/流程管理，并且该应用程序处理大量 DNS 任务，因此如果我从远程服务器运行开发应用程序，并在保存时进行 Rsyncing 或 SFTPing(仍在整理中)，这是最简单的.

既然如此，开发应用程序与生产应用程序位于同一虚拟机上是理想的情况。但是，PM2 部署配置文件 (ecosystem.config.js) 的结构似乎无法实现这一点，因为当我运行 pm2 deploydevelopment 时，开发版本取代虚拟机上的生产过程。

这是我所拥有的:

module.exports = {
  apps: [
    {
      name: "APP NAME",
      script: "app.js",
      env_development: {
        NODE_ENV: "development",
        ...
      },
      env_production: {
        NODE_ENV: "production",
        ...
      }
    }
  ],
  deploy: {
    production: {
      user: "user",
      host: ["123.123.123.123"],
      ref: "origin/master",
      repo: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bed9d7cafed9d7cad2dfdc90ddd1d3" rel="noreferrer noopener nofollow">[email protected]</a>:me/repo.git",
      path: "/var/www/app",
      "post-deploy":
        "npm install && pm2 reload ecosystem.config.js --env production"
    },
    development: {
      user: "user",
      host: ["123.123.123.123"],
      ref: "origin/master",
      repo: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2c4b45586c4b4558404d4e024f4341" rel="noreferrer noopener nofollow">[email protected]</a>:me/repo.git",
      path: "/var/www/app-dev",
      "post-deploy":
        "npm install && pm2 reload ecosystem.config.js --env development"
    }
  }
};

对于实现这一目标的最佳方法有什么想法吗？

引用此PR后，我想你应该能够添加 append_env_to_name: true作为 apps 中对象的属性ecosystem.config.js 的数组:

所以你更新了ecosystem.config.js文件如下:

module.exports = {
  apps: [
    {
      name: "APP NAME",
      append_env_to_name: true // <===== add this line
      script: "app.js",
      env_development: {
        NODE_ENV: "development",
        ...
      },
      env_production: {
        NODE_ENV: "production",
        ...
      }
    }
  ],
  deploy: {
    production: {
      user: "user",
      host: ["123.123.123.123"],
      ref: "origin/master",
      repo: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="72151b0632151b061e13105c111d1f" rel="noreferrer noopener nofollow">[email protected]</a>:me/repo.git",
      path: "/var/www/app",
      "post-deploy":
        "npm install && pm2 reload ecosystem.config.js --env production"
    },
    development: {
      user: "user",
      host: ["123.123.123.123"],
      ref: "origin/master",
      repo: "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6e09071a2e09071a020f0c400d0103" rel="noreferrer noopener nofollow">[email protected]</a>:me/repo.git",
      path: "/var/www/app-dev",
      "post-deploy":
        "npm install && pm2 reload ecosystem.config.js --env development"
    }
  }
};
