[英]Node/Express server deploy with Heroku and PM2
Attempting to add clustering ability via PM2 and deploy via my Node/Express application.尝试通过 PM2 添加集群功能并通过我的 Node/Express 应用程序进行部署。
I've set up the following command:我已经设置了以下命令:
pm2 start build/server/app.js -i max
The above works fine locally.以上在本地运行良好。 I'm testing the functionality on a staging environment on Heroku via Performance 1X.
我正在通过 Performance 1X 在 Heroku 的暂存环境中测试该功能。
The above shows the log for the command but attempting 1 instance rather than max
.上面显示了命令的日志,但尝试 1 个实例而不是
max
。 It shows typical info after successfully running pm2 start however you can see app immediately crashes afterward.它在成功运行 pm2 start 后显示典型信息,但是您可以看到应用程序随后立即崩溃。
Any advice or guidance is appreciated.任何建议或指导表示赞赏。
I ended up using the following documentation: https://pm2.keymetrics.io/docs/integrations/heroku/我最终使用了以下文档: https ://pm2.keymetrics.io/docs/integrations/heroku/
Using a ecosystem.config.js
with the following:使用具有以下内容的
ecosystem.config.js
:
module.exports = {
apps : [
{
name: `app-name`,
script: 'build/server/app.js',
instances: "max",
exec_mode: "cluster",
env: {
NODE_ENV: "localhost"
},
env_development: {
NODE_ENV: process.env.NODE_ENV
},
env_staging: {
NODE_ENV: process.env.NODE_ENV
},
env_production: {
NODE_ENV: process.env.NODE_ENV
}
}
],
};
Then the following package.json
script handles the deployment per the environment I am looking to deploy eg production:然后以下
package.json
脚本根据我要部署的环境处理部署,例如生产:
"deploy:cluster:prod": "pm2-runtime start ecosystem.config.js --env production --deep-monitoring",
I got the same error but I fixed it by adding我得到了同样的错误,但我通过添加来修复它
{
"preinstall":"npm I -g pm2",
"start":"pm2-runtime start build/server/app.js -i 1"
}
To my package.json file This is advised for production environment But running到我的 package.json 文件这建议用于生产环境但正在运行
pm2 start build/server/app.js -i max
