Nginx访问日志
1. 进入配置文件
[root@gary-tao src]# 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@gary-tao src]# 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@gary-tao src]# /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@gary-tao src]# /usr/local/nginx/sbin/nginx -s reload
4.使用curl测试
[root@gary-tao src]# curl -x127.0.0.1:80 test.com -I
HTTP/1.1 200 OK
Server: nginx/1.12.1
Date: Thu, 04 Jan 2018 09:19:09 GMT

[root@gary-tao src]# curl -x127.0.0.1:80 test2.com/admin -I
HTTP/1.1 301 Moved Permanently

Content-Type: text/html

Location: http://test.com/admin
[root@gary-tao src]# curl -x127.0.0.1:80 test2.com/admin/index.html -I
HTTP/1.1 301 Moved Permanently

[root@gary-tao src]# 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@gary-tao src]# 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 $nginx_pid` //跟Nginx的-s重新加载配置文件一样
2.执行脚本
sh执行，-x是显示执行的过程
[root@gary-tao src]# sh -x /usr/local/sbin/nginx_log_rotate.sh
++ date -d '-1 day' +%Y%m%d
+ d=20180103
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls php_errors.log test.com.log
+ for log in '`ls *.log`'
+ mv php_errors.log php_errors.log-20180103
+ for log in '`ls *.log`'
+ mv test.com.log test.com.log-20180103
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 62748
[root@gary-tao src]# ls /tmp/
mysql.sock systemd-private-b666888e47f84d62afce0dcb90bdfc91-vmtoolsd.service-09q5L2
pear systemd-private-fdc53ff508e94ecda3c5a90dad98a792-vmtoolsd.service-O5O620
php_errors.log-20180103 test.com.log
php-fcgi.sock test.com.log-20180103
systemd-private-6fc6799999fe42dd97426bde338fb145-vmtoolsd.service-qi1M6k
3.任务计划
[root@gary-tao src]# crontab -e //添加任务计划
增加如下内容：
0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh
静态文件不记录日志和过期时间
1.修改虚拟主机配置文件
[root@gary-tao src]# vim /usr/local/nginx/conf/vhost/test.com.conf
增加如下内容：
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ //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@gary-tao src]# /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@gary-tao src]# /usr/local/nginx/sbin/nginx -s reload
3.使用curl测试
[root@gary-tao src]# cd /data/wwwroot/test.com
[root@gary-tao test.com]# ls
admin 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
