Nginx访问日志
1. 进入配置文件
[root@panting linux]# vim /usr/local/nginx/conf/nginx.conf //搜索log_format参考更改配置成如下：log_format aming '$remote_addr $http_x_forwarded_for [$time_local]'
如图：
日志格式字段含义如下：
combined_realip为日志格式的名字，后面可以调用它。
2.到虚拟主机配置文件中指定访问日志的路径。
[root@panting linux]# vim /usr/local/nginx/conf/vhost/test.com.conf增加如下内容：access_log /tmp/test.com.log combined_realip; //这里的combined_realip就是在nginx.conf中定义的日志格式名字
如图：
3.测试语法及重新加载配置
[root@panting linux]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@panting linux]# /usr/local/nginx/sbin/nginx -s reload
4.使用curl测试
[root@panting linux]# curl -x127.0.0.1:80 test.com -IHTTP/1.1 200 OKServer: nginx/1.12.1Date: Thu, 04 Jan 2018 09:19:09 GMTContent-Type: text/html Content-Length: 15 Last-Modified: Wed, 03 Jan 2018 13:03:42 GMT Connection: keep-alive ETag: "5a4cd4ae-f" Accept-Ranges: bytes [root@panting linux]# curl -x127.0.0.1:80 test2.com/admin -I HTTP/1.1 301 Moved Permanently Server: nginx/1.12.1 Date: Thu, 04 Jan 2018 09:19:54 GMT Content-Type: text/html Content-Length: 185 Connection: keep-alive Location: http://test.com/admin [root@panting linux]# curl -x127.0.0.1:80 test2.com/admin/index.html -I HTTP/1.1 301 Moved Permanently Server: nginx/1.12.1 Date: Thu, 04 Jan 2018 09:20:04 GMT Content-Type: text/html Content-Length: 185 Connection: keep-alive Location: http://test.com/admin/index.html [root@panting linux]# cat /tmp/test.com.log 127.0.0.1 - [04/Jan/2018:17:19:09 +0800] test.com "/" 200 "-" "curl/7.29.0" 127.0.0.1 - [04/Jan/2018:17:19:54 +0800] test2.com "/admin" 301 "-" "curl/7.29.0" 127.0.0.1 - [04/Jan/2018:17:20:04 +0800] test2.com "/admin/index.html" 301 "-" "curl/7.29.0"
Nginx日志切割
1.自定义一个脚本
[root@panting linux]# vim /usr/local/sbin/nginx_log_rotate.sh定义如下内容：#!/bin/bash## 假设nginx的日志存放路径为/data/logs/d=`date -d "-1 day" +%Y%m%d` //这个日期是昨天的日期，因为日志切割是第二天才执行这个脚本的。 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 $nginx_pid` //跟Nginx的-s重新加载配置文件一样
2.执行脚本
sh执行，-x是显示执行的过程
[root@panting linux]# sh -x /usr/local/sbin/nginx_log_rotate.sh++ date -d '-1 day' +%Y%m%d+ d=20180103+ logdir=/tmp/+ nginx_pid=/usr/local/nginx/logs/nginx.pid + cd /tmp/ ++ ls php_errors.log test.com.log + for log in '`ls *.log`' + mv php_errors.log php_errors.log-20180103 + for log in '`ls *.log`' + mv test.com.log test.com.log-20180103 ++ cat /usr/local/nginx/logs/nginx.pid + /bin/kill -HUP 62748 [root@panting linux]# ls /tmp/ mysql.sock systemd-private-b666888e47f84d62afce0dcb90bdfc91-vmtoolsd.service-09q5L2 pear systemd-private-fdc53ff508e94ecda3c5a90dad98a792-vmtoolsd.service-O5O620 php_errors.log-20180103 test.com.log php-fcgi.sock test.com.log-20180103 systemd-private-6fc6799999fe42dd97426bde338fb145-vmtoolsd.service-qi1M6k
3.任务计划
[root@panting linux]# crontab -e //添加任务计划增加如下内容：0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh
静态文件不记录日志和过期时间
1.修改虚拟主机配置文件
[root@panting linux]# vim /usr/local/nginx/conf/vhost/test.com.conf增加如下内容：location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ //匹配脱义静态文件 { expires 7d; //配置过期时间 access_log off; } location ~ .*\.(js|css)$ //匹配js,css文件 { expires 12h; access_log off; } 如图：
2.测试语法及重新加载配置
[root@panting linux]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@panting linux]# /usr/local/nginx/sbin/nginx -s reload
3.使用curl测试
[root@panting linux]# cd /data/wwwroot/test.com[root@gary-tao test.com]# lsadmin index.html[root@gary-tao test.com]# vim 1.gif[root@gary-tao test.com]# echo "dgagadgadgs" > /data/wwwroot/test.com/2.js [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/1.gif dggagadggagdag [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/2.js dgagadgadgs [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/index.html “test.com” [root@gary-tao test.com]# cat /tmp/test.com.log 127.0.0.1 - [04/Jan/2018:18:53:20 +0800] test.com "/index.html" 200 "-" "curl/7.29.0" [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/index.html “test.com” [root@gary-tao test.com]# cat /tmp/test.com.log 127.0.0.1 - [04/Jan/2018:18:53:20 +0800] test.com "/index.html" 200 "-" "curl/7.29.0" 127.0.0.1 - [04/Jan/2018:18:53:53 +0800] test.com "/index.html" 200 "-" "curl/7.29.0" [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/2.js dgagadgadgs [root@gary-tao test.com]# cat /tmp/test.com.log 127.0.0.1 - [04/Jan/2018:18:53:20 +0800] test.com "/index.html" 200 "-" "curl/7.29.0" 127.0.0.1 - [04/Jan/2018:18:53:53 +0800] test.com "/index.html" 200 "-" "curl/7.29.0" [root@gary-tao test.com]# curl -x127.0.0.1:80 test.com/2.jsagdaga404 Not Found 404 Not Found
