                         # 正确的进程数目依赖于Cpu的核心数目
$ pm2 start app.js --name my-api # 命名进程
$ pm2 list               # 显示所有进程状态
$ pm2 monit              # 监视所有进程
$ pm2 logs               # 显示所有进程日志
$ pm2 stop all           # 停止所有进程

$ pm2 stop 0             # 停止指定的进程
$ pm2 restart 0          # 重启指定的进程
$ pm2 startup            # 产生 init 脚本 保持进程活着
$ pm2 web                # 运行健壮的 computer API endpoint (http://localhost:9615)

The simplest way to start, daemonize and monitor your application is by using this command line:

$ pm2 start app.js

Or start any other application easily:

$ pm2 start bashscript.sh
$ pm2 start python-app.py --watch
$ pm2 start binary-file -- --port 1520

Some options you can pass to the CLI:

# Specify an app name
--name <app_name>

# Watch and Restart app when files change
--watch

# Set memory threshold for app reload
--max-memory-restart <200MB>

# Specify log file
--log <log_path>

# Pass extra arguments to the script
-- arg1 arg2 arg3

# Delay between automatic restarts
--restart-delay <delay in ms>

# Prefix logs with time
--time

# Do not auto restart app
--no-autorestart

# Specify cron for forced restart
--cron <cron_pattern>

# Attach to application log
--no-daemon
 
$ pm2 restart app_name
$ pm2 reload app_name
$ pm2 stop app_name
$ pm2 delete app_name
