12.10 Nginx访问日志

• 除了在主配置文件nginx.conf里定义日志格式外，还需要在虚拟主机配置文件中增加
• access_log /tmp/1.log combined_realip;
• 这里的combined_realip就是在nginx.conf中定义的日志格式名字
• -t && -s reload
• curl -x127.0.0.1:80 test.com -I
• cat /tmp/1.log

[root@zgxlinux-01 vhost]# vim ../nginx.conf         #修改日志名称

[root@zgxlinux-01 vhost]# vim test.com.conf

[root@zgxlinux-01 vhost]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@zgxlinux-01 vhost]# /usr/local/nginx/sbin/nginx -s reload

12.11 、Nginx日志切割

• 自定义shell 脚本
• vim /usr/local/sbin/nginx_log_rotate.sh//写入如下内容

#! /bin/bash
## 假设nginx的日志存放路径为/data/logs/
d=`date -d "-1 day" +%Y%m%d` 
logdir="/data/logs"
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`

• 任务计划
• 0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh

#操作过程

[root@zgxlinux-01 vhost]# vim /usr/local/sbin/nginx_logrotate.sh

[root@zgxlinux-01 vhost]# sh -x  /usr/local/sbin/nginx_logrotate.sh       #执行这个脚本，-x表示查看执行过程
++ date -d '-1 day' +%Y%m%d
+ d=20181130
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls test.com.log
+ for log in '`ls *.log`'
+ mv test.com.log test.com.log-20181130
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 4421

[root@zgxlinux-01 vhost]# find /tmp/ -name *.log-* -type f -mtime +30 |xargs rm   #长时间以后需要清理日志，xargs进行删除操作。
rm: 缺少操作数

12.12 、静态文件不记录日志和过期时间

• 配置如下

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
          expires      7d;
          access_log off;
    }
location ~ .*\.(js|css)$
    {
          expires      12h;
          access_log off;
    }
