指示pm2不要在json文件中启动多个实例
以下是pm2 process.jsonconfiguration文件。 该应用程序使用该命令盯着
pm2 start /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" } }] } 产量

看起来这个过程试图启动10次。 如何问pm2不启动多个实例？
编辑2：
添加属性
"instances" : 1
到JSON文件按预期工作，并只启动一个进程。 但它引发了警告
[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.
如何在fork模式下启动进程，仍然有单个实例。
在json设置中指定exec_mode和实例键：
{ "apps" : [{ "exec_mode": "fork", "instances": 1 }] }
