日志管理
pm2 install pm2-logrotate
pm2-logrotate配置
max_size(默認(rèn) 10M): 最大為多少時(shí)進(jìn)行分割闰蚕，例如: 10G, 10M, 10Kretain(Defaults to all): This number is the number of rotated logs that are keep at any one time, it means that if you have retain = 7 you will have at most 7 rotated logs and your current one.compress (默認(rèn) false): 是否壓縮日志
dateFormat (默認(rèn) YYYY-MM-DD_HH-mm-ss) : 日志格式
rotateModule (Defaults to true) : Rotate the log of pm2's module like other apps
workerInterval (Defaults to 30 in secs) : You can control at which interval the worker is checking the log's size (minimum is 1)
rotateInterval (Defaults to 0 0 * * * everyday at midnight): This cron is used to a force rotate when executed. We are using node-schedule to schedule cron, so all valid cron for node-schedule is valid cron for this option. Cron style :
TZ (Defaults to system time): This is the standard tz database timezone used to offset the log file saved. For instance, a value of Etc/GMT-1, with an hourly log, will save a file at hour 14 GMT with hour 13 GMT-1 in the log name.
修改日志配置
pm2 set pm2-logrotate:max_size 2048K // 設(shè)置切割日志大小
pm2 set pm2-logrotate:rotateInterval '* * */1 * *' //每小時(shí)備份
pm2 set pm2-logrotate:compress true //壓縮
pm2 set pm2-logrotate:retain 3 //備份最多3份栈拖，也就是備份最進(jìn)3小時(shí)的日志
