Nginx访问日志、Nginx日志切割、静态文件不记录日志和过期时间介绍
Nginx访问日志1. 进入配置文件
# 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
# 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
# /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
# /usr/local/nginx/sbin/nginx -s> 4.使用curl测试
# curl -x127.0.0.1:80 test.com -I

127.0.0.1 - test2.com "/admin/index.html" 301 "-" "curl/7.29.0"
Nginx日志切割
1.自定义一个脚本
# 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
# 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
# ls /tmp/
mysql.sock systemd-private-b666888e47f84d62afce0dcb90bdfc91-vmtoolsd.service-09q5L2
pear systemd-private-fdc53ff508e94ecda3c5a90dad98a792-vmtoolsd.service-O5O620

systemd-private-6fc6799999fe42dd97426bde338fb145-vmtoolsd.service-qi1M6k
3.任务计划
# 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
# 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
# /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
# /usr/local/nginx/sbin/nginx -s> 3.使用curl测试
# cd /data/wwwroot/test.com
# ls
adminindex.html
# vim 1.gif
# echo "dgagadgadgs" > /data/wwwroot/test.com/2.js
# curl -x127.0.0.1:80 test.com/1.gif

# curl -x127.0.0.1:80 test.com/2.js

# cat /tmp/test.com.log
