问题描述
根据此问题，pm2应该重新启动崩溃的应用程序.
According to this question, pm2 should restart crashed applications.
当我的应用程序崩溃时，什么都没有发生，并且pm2 list中缺少该过程.我必须以某种方式激活自动重启选项"吗?
When my application crashes nothing happens and the process is missing from pm2 list. Do I have to somehow activate an 'auto restart option'?
我正在使用:
- pm2 v0.12.3
- 节点v0.11.14
- Amazon Linux
推荐答案
尝试使用PM2作为监视Node.js应用程序的唯一方法的效果很差.最后，我采用的方法是使用 Monit 来监视应用程序过程并在使用monit配置脚本来执行startOrRestart或stop的过程.例如，在monitrc文件中:
I've had poor results trying to use PM2 as the sole means by which to monitor my Node.js applications. In the end the approach I took was to use to Monit to monitor the application process and use pm2 within the monit configuration script to startOrRestart or stop the process. For example, in a monitrc file:
check process node_app matching /home/webapps/node_app/app.js
start program = "/bin/bash -lc 'cd /home/webapps/node_app && PM2_HOME=/home/webapps/.pm2 /usr/bin/pm2 startOrRestart processes.json'"
stop program = "/bin/bash -lc 'cd /home/webapps/node_app && PM2_HOME=/home/webapps/.pm2 /usr/bin/pm2 stop processes.json'"
check process node_app matching /home/webapps/node_app/app.js
start program = "/bin/bash -lc 'cd /home/webapps/node_app && PM2_HOME=/home/webapps/.pm2 /usr/bin/pm2 startOrRestart processes.json'"
stop program = "/bin/bash -lc 'cd /home/webapps/node_app && PM2_HOME=/home/webapps/.pm2 /usr/bin/pm2 stop processes.json'"
Not only does this allow you to "watch the watcher" it helps as a work-around for the persistent PM2 fails to restart applications after a reboot bug.
