Linux下nginx生成日志自动切割

1、编辑切割日志的 shell 程序，目录自定

#vi /data/nginx/cut_nginx_log.sh

输入代码：

#!/bin/bash

# This script run at 00:00

function cutAccess()
{
    dir=$1
    newdir="${dir}/$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")"
    suffix=$(date -d "yesterday" +"%Y%m%d")
    mkdir -p $newdir
    mv ${dir}/access.log ${newdir}/access.$suffix.log
}

cutAccess "/home/wwwlogs/www.yourdomain.com/"
cutAccess "/home/wwwlogs/www.yourdomain-1.com/"
cutAccess "/home/wwwlogs/www.yourdomain-2.com/"

# 重启 nginx
kill -HUP `cat /usr/local/nginx/logs/nginx.pid`

2、加入定时任务，每天0点自动切割

# crontab -e
0 0 * * * /bin/bash /data/nginx/cut_nginx_log.sh

3、nginx 日志格式

log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
            '$status $body_bytes_sent "$http_referer" '
            '"$http_user_agent" $http_x_forwarded_for';
access_log  /home/wwwlogs/www.yourdomain.com/access.log  access;
