根据时间自动切分 Nginx.log
之前是用脚本配合 crontab 来做日志切分:
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
最近发现可以直接在 nginx.conf 里通过 $time_iso8601
提取时间进行设置:
if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
}
access_log /var/log/nginx/$year-$month-$day-access.log;
时间粒度可以更为精细:
if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
set $minutes $5;
set $seconds $6;
}
