nginx日志会随着访问量而变大,较大的日志会影响分析日志时对日志的分析和处理,我们可以使用shell对nginx日志进行定时分割,以周或者天,对于时间久的日志可以定时删除,减小磁盘的浪费

代码:

# cat logrotate.sh 

#!/bin/bash
#rotate nginx logs
#writen by Aiker
PATH=$PATH://usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
logs_path=/var/log/nginx
d=$(date -d "-1 day" +%F)
mv $logs_path/access.log $logs_path/access_${d}.log
mv $logs_path/error.log $logs_path/error_${d}.log
#向nginx主进程发送USR1信号重新打开日志文件
kill -USR1 $(cat /var/run/nginx.pid)

针对多个日志的切割:

#!/bin/bash
#rotate nginx logs
#writen by Aiker
PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
logs_path=/var/log/nginx
d=$(date -d "-1 day" +%F)
cd ${logs_path}
for logs in `ls *.log`
    do
        mv $logs $logs-$d
done

#向nginx主进程发送USR1信号重新打开日志文件也可以:/bin/kill -HUP `cat $nginx_pid`
kill -USR1 $(cat /var/run/nginx.pid)

定时切割日志:
crontab -e

# ll /var/log/nginx/
