PM2启动配置文件参数比较全的一个。如下：{ "name" : "node-app", "cwd" : "/srv/node-app/current", "args" : ["--toto=heya coco", "-d", "1"], "script" : "bin/app.js", "node_args" : ["--harmony", " --max-stack-size=102400000"], "log_date_format" : "YYYY-MM-DD HH:mm Z", "error_file" : "/var/log/node-app/node-app.stderr.log", "out_file" : "log/node-app.stdout.log", "pid_file" : "pids/node-geo-api.pid", "instances" : 6, //or 0 => 'max' "min_uptime" : "200s", // 200 seconds, defaults to 1000 "max_restarts" : 10, // defaults to 15 "max_memory_restart": "1M", // 1 megabytes, e.g.: "2G", "10M", "100K", 1024 the default unit is byte. "cron_restart" : "1 0 * * *", "watch" : false, "ignore_watch" : ["[\\/\\\\]\\./", "node_modules"], "merge_logs" : true, "exec_interpreter" : "node", "exec_mode" : "fork", "autorestart" : false, // enable/disable automatic restart when an app crashes or exits "vizion" : false, // enable/disable vizion features (versioning control) // Default environment variables that will be injected in any environment and at any start "env": { "NODE_ENV": "production", "AWESOME_SERVICE_API_TOKEN": "xxx" } "env_*" : { "SPECIFIC_ENV" : true } }比较有用的参数:cron_restart:定时启动，解决重启能解决的问题max_memory_restart：解决内容不够用的问题，不过会有风险【数据丢失】
