当使用PM2When managing multiple apps,可以使用 JS profiles to manage them.

生成配置文件

Use the command below to generate a simple configuration file：

pm2 init simple

会生成一个简单的 ecosystem.config.js:

module.exports = {
    apps: [{
        name:"app1",
        script:"./app.js",
    }]
}

If a custom configuration file is created,Make sure the filename is .config.js 结尾的,这样 PM2 It can be managed as a configuration file.

操作配置文件

compared to performing an action on an application,You can use the configuration file directly 启动/停止/重新启动/删除 All applications in the configuration file：

# 启动所有应用程序
pm2 start ecosystem.config.js

# 关闭所有应用
pm2 stop ecosystem.config.js

# 重启
pm2 restart ecosystem.config.js

# 重载
pm2 reload ecosystem.config.js

# 删除
pm2 delete ecosystem.config.js

Operates the specified process

可以使用--only <app_name>Operate a specific application:

pm2 start ecosystem.config.js --only api-app

注意：--only The choice can also be right start/restart/stop/delete 操作.

It can also be separated by commas,Operates multiple specific applications：

pm2 start ecosystem.config.js --only "api-app,worker-app"

切换环境

可以通过设置 env_* to set different environment variables：

module.exports = {
    apps:[{
        name:"app1",
        script:"./app.js",
        env_production:{
            NODE_ENV:"production"
        },
        env_development:{
            NODE_ENV:"development"
        }
    }]
}

可以通过 --env [env name] to switch environment variables：
