nginx访问日志
查看nginx.conf文件
vim /usr/local/nginx/conf/nginx.conf
中间有一行是定义log的格式
log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
' $host "$request_uri" $status'
' "$http_referer" "$http_user_agent"';
其中''包围起来的不算一行,只是为了美观才分行显示,分行显示就必须加上''号;
含义: combined_realip:定义日志格式别名,默认为combined_realip,这里我会改为test001; $remote_addr:客户端ip也就是出口公网ip; $http_x_forwarded_for:代理服务器ip; $time_local:服务器本地时间; $host:访问主机名(域名); $request_uri:访问的url地址; $status:状态码,比如404; $http_referer:referer; $http_user_agent:也就是访问的浏览器类型,比如傲游7;
编辑虚拟web配置
vim /usr/local/nginx/conf/vhost/test.com.conf
增加access_log /tmp/test.com.log combined_realip;
其中combined_realip是定义名称,记得与nginx.conf匹配;
检错与重新加载
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
访问与测试
curl -x127.0.0.1:80 test.com/1.html -I
访问成功200 查看日志
cat /tmp/test.com.log
127.0.0.1 - [15/Mar/2018:03:13:28 +0800] test.com "/1.html" 200 "-" "curl/7.29.0"
日志切割
创建shell脚本
vim /usr/local/sbin/nginx_log_rotate.sh
代码
#! /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 $nginx_pid`
执行脚本(可不执行)
sh -x /usr/local/sbin/nginx_log_rotate.sh
[root@shu-test ~]# sh -x /usr/local/sbin/nginx_log_rotate.sh
++ date -d '-1 day' +%Y%m%d
+ d=20180314
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls php_errors.log test.com.log
+ for log in '`ls *.log`'
+ mv php_errors.log php_errors.log-20180314
+ for log in '`ls *.log`'
+ mv test.com.log test.com.log-20180314
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 1574
[root@shu-test ~]#
任务计划执行脚本
crontab -e
写入脚本
0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh
意思:每天凌晨0点执行脚本/usr/local/sbin/nginx_log_rotate.sh
如何脚本删除log
find /tmp/ -name *.log-* -type f -mtime +30 |xargs rm
静态文件不记录日志和过期时间
编辑web虚拟文件
vim /usr/local/nginx/conf/vhost/test.com.conf
增加代码
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 7d;
access_log off;
}
location ~ .*\.(js|css)$
{
expires 12h;
access_log off;
}
所有代码预览
