Nginx access log
Log format
vim /usr/local/nginx/conf/nginx.conf //Search log_format 
In addition to defining the log format in the main configuration file nginx.conf, you also need to add
access_log /tmp/1.log combined_realip to the virtual host configuration file ;
The combined_realip here is the log format name defined in nginx.conf
-t && -s reload
curl -x127.0.0.1:80 test.com -I
cat /tmp/1.log
[root@izbp1iei7rfo61naj23hlez vhost]# cat /tmp/1.log
127.0.0.1 - [25/Apr/2018:22:03:28 +0800] test3.com "/index.html" 301 "-" "curl/7.29.0"
127.0.0.1 - [25/Apr/2018:22:03:50 +0800] test.com "/index.html" 200 "-" "curl/7.29.0"
Nginx log cutting
The custom shell script
vim /usr/local/sbin/nginx_log_rotate.sh// writes the following content
#! /bin/bash
#假设nginx的日志存放路径为/tmp/
d=`date -d "-1 day" +%Y%m%d`
logdir="/tmp/"
nginx_pid="/usr/local/nginx/logs/nginx.pid"
cd $logdir
for log in `ls *.log`
do
mv $log $log-$d
done
/bin/kill -HUP `cat $nginx_pid`perform tasks
[root@izbp1iei7rfo61naj23hlez vhost]# sh -x /usr/local/sbin/nginx_log_rotate.sh
