pm2启动不起作用 [英] pm2 startup doesn't work
问题描述
我成功设置了我的nodejs服务器，并且在Ubuntu 15.04服务器上使用它，我的问题是我希望我的节点应用程序在服务器重新启动时能够继续运行，所以我尝试了pm2，forever和crontab但是它们都不适合我，重新启动后，我需要手动启动节点应用程序.
I setup my nodejs server successfully and I'm using it on Ubuntu 15.04 server, my issue is that I want my node applications to keep running when the server reboots so I tried pm2, forever and crontab but none of them worked for me, after rebooting I need to start the node application manually.
我尝试了pm2，如下所示:
pm2 startup ubuntu
pm2 start appname
pm2 save
pm2-init.sh文件:
The pm2-init.sh file:
#!/bin/bash
# chkconfig: 2345 98 02

}

export PM2_HOME
super $PM2 resurrect
}
stop() {
super $PM2 dump
super $PM2 delete all
super $PM2 kill
}
restart() {

stop
start
}
reload() {

super $PM2 reload all
}
status() {
echo "Status for $NAME:"
super $PM2 list

}

exit $RETVAL
那没有用，所以我尝试使用crontab，如下所示:
首先，我创建一个脚本并将其命名为starter.sh
That didn't work, so I tried to use crontab as follow:
First, I create a script and named it starter.sh
#!/bin/bash
pm2 start /home/bashar/www/node/server.js
然后打开crontab编辑器:
crontab -e
@reboot /home/bashar/www/node/server.js
上述方法也没有在服务器重新启动时启动我的应用程序.
Also the above method didn't start my application on the server reboot.
请提出建议，
推荐答案
pm2在重新引导期间似乎存在错误.将pm2添加到/etc/init.d中的自动启动进程后，该脚本在正常处理下可以正常工作，但在重新启动后却有些奇怪:它将pm2.dump文件清空.像这样的错误报告 ，但是到目前为止，它仍然是一个错误...
pm2 seems to have a bug during the reboot. After adding pm2 to the automagically starting processes in /etc/init.d, the script works fine under normal processing, but does something weird under a reboot: it wipes the pm2.dump file empty. There are several bug reports like this one, but so far it's still a bug...
我发现的最简单的解决方法如下:
The easiest work-around that I've found is as follows:
- 编辑/etc/init.d/pm2-init.sh，并在stop()部分中注释掉"super $ PM2 dump"行
- 每当修改pm2进程列表时，请记住手动进行"pm2转储"
如果有人有更永久的解决方案，请让我知道...:)
If anyone has a more permanent solution, please let me know... :)
