发生PM2错误=&gt；通过信号[SIGINT]退出，代码为[1] [英] PM2 error occurred => exited with code [1] via signal [SIGINT]

问题描述

NodeJS在PM2上运行了很长时间。每天都有玉米清理PM2日志

0 0 * * * find /home/user/.pm2/logs* -mtime +2 -exec rm -rf {} ;

下面的错误出现了1000次，然后PM2停止工作，然后当我重新加载实例时，它像往常一样正常工作。

此错误的原因可能是什么？

推荐答案

您正尝试仅使用rm清理日志文件。你不能这么做，™。在Linux和其他派生于UNIX的操作系统上，即使您rm从目录中写入日志文件，写入日志文件的程序也会使其保持打开状态。在编写该文件的程序关闭(或终止)该文件之前，该文件实际上不会消失。这适用于所有类型的软件，而不仅仅是PM2。

如果您只想清除日志文件并重新开始，pm2 flush命令就是为您准备的。

如果要将旧日志保存一段有限的时间，则应调查pm2's log rotation addon。

这样的命令可能会帮您解决问题

# install the pm2 addon ... notice it says pm2 install, not npm install
pm2 install pm2-logrotate
# rotate when a logfile fills to ten megabytes
pm2 set pm2-logrotate:max_size 10M
# gzip compress the rotated logs to save space
pm2 set pm2-logrotate:compress true
# force rotation at 00:00 each day even if logfile is not full 
pm2 set pm2-logrotate:rotateInterval '0 0 * * *'

您可以说pm2 config pm2-logrotate让它向您显示其当前设置。
