# 根据有效CPU数目启动最大进程数目运行js程序
pm2 start app.js -i max

# 启动3个进程运行js程序
pm2 start app.js -i 3

#用fork模式启动 app.js 而不是使用 cluster 并且传递参数 (-a 123)
pm2 start app.js -x -- -a 123

# 启动一个进程并把它命名为 aa
pm2 start app.js --name aa

# 运行一次sh 脚本
pm2 start scrip.sh -x --interpreter bash --no-autorestart

# 运行py 脚本
pm2 start scrip.py -x --interpreter python
