指示pm2在json文件中不啓動多個實例

以下是pm2 process.json配置文件。該應用程序是使用命令指示pm2在json文件中不啓動多個實例

PM2開始/root/src/sample_v2/deploy-scripts/processes.json

{ 
    "apps" : [{ 
    "name"  : "sample_app_v2", 
    "script"  : "bin/www", 
    "log_date_format" : "YYYY-MM-DD HH:mm Z", 
    "node_args" : "--harmony", 
    "cwd"   : "/root/src/sample_v2", 
    "env": { 
     "NODE_ENV": "production", 
     "AWESOME_SERVICE_API_TOKEN": "xxx", 
     "TZ": "Europe/Amsterdam" 
    } 
    }] 
}

輸出

看起來像這個過程試圖啓動次。如何問pm2不啓動多個實例？

編輯2：

添加屬性

"instances" : 1

的JSON文件按預期工作，並開始只有一個進程。但它拋出警告

[WARN] You should not use the cluster_mode (-i) in production, it's still a beta feature. A front HTTP load balancer or interaction with NGINX will be developped in the future.

如何開始在叉模式過程中，仍然有一個實例。

對我來說，它看起來像它的唯一一次首發。但是在某個地方有一個錯誤。默認模式是'fork_mode'，所以它只會啓動你的進程的一個實例。 – soyuka 2015-04-01 05:53:36

在應用程序的開始處打印文本** mongoclient.connect **。在這種情況下，它打印10次。如果只啓動一次，它只會打印一次。 – 2015-04-01 20:33:34

@soyuka也請看這個問題的編輯。 – 2015-04-01 20:46:45

在JSON設置指定exec_mode和實例鍵：

{ 
    "apps" : [{ 
    "exec_mode": "fork", 
    "instances": 1 
    }] 
}
