Node.js——PM2命令

npm install pm2 -g
pm2 update

附pm2命令：

$ npm install pm2 -g     # 命令行安装 pm2 
$ pm2 start app.js -i 4 # 后台运行pm2，启动4个app.js # 也可以把'max' 参数传递给 start # 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 restart all # 重启所有进程 $ pm2 reload all # 0 秒停机重载进程 (用于 NETWORKED 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) $ pm2 delete 0 # 杀死指定的进程 $ pm2 delete all # 杀死全部进程

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

Restart application on changes

It’s pretty easy with the --watch option:

$ cd /path/to/my/app
$ pm2 start env.js --watch --ignore-watch="node_modules"
