访问日志
1、定义日志格式
|

|
[root@plinuxos ~]# vi /usr/local/nginx/conf/nginx.conf
log_format log001 '$remote_addr $http_x_forwarded_for [$time_local]'
' $host "$request_uri" $status'
' "$http_referer" "$http_user_agent"';
|
▎Nginx日志格式：
|
$remote_addr |
客户端IP(公网IP) |
|
$http_x_forwarded_for |
代理服务器的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 |
|
$http_referer |
referer |
|
$http_user_agent |
user_agent |
2、增加访问日志项

[root@plinuxos ~]# vi /usr/local/nginx/conf/vhost/default.conf
server{ listen 80 default_server;
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
access_log /tmp/default.log log001;##增加该行，该行元素：访问日志，存储地址，格式名称
} |
3、检查与重载
|

|
[root@plinuxos ~]# /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@plinuxos ~]# /usr/local/nginx/sbin/nginx -s reload
|

[root@plinuxos ~]# curl -x127.0.0.1:80 aaa.com/index.html

“This is a default site.”[root@plinuxos ~]# cat /tmp/default.log
127.0.0.1 - [12/Aug/2017:10:34:45 +0800] aaa.com "/index.html" 200 "-" "curl/7.29.0"
127.0.0.1 - [12/Aug/2017:10:34:52 +0800] aaa1.com "/index.html" 200 "-" "curl/7.29.0"

日志切割
1、日志切割脚本

|
[root@plinuxos ~]# vi /usr/local/sbin/nginx_log_rotate.sh
#! /bin/bashd=`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`
|
▎KILL参数：
INT：快速关闭，是当用户键入<Control-C>时由终端驱动程序发送的信号。
TERM：快速关闭，请求彻底终止某项执行操作，它期望接收进程清除自给的状态并退出。
HUP：平滑启动，重新加载配置文件。
QUIT：从容关闭。
2、执行脚本

[root@plinuxos tmp]# sh -x /usr/local/sbin/nginx_log_rotate.sh
++ date -d '-1 day' +%Y%m%d
+ d=20170811+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls default.log
+ for log in '`ls *.log`'
+ mv default.log default.log-20170811
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 89689

3、检查效果

|
[root@plinuxos tmp]# ls
default.log default.log-20170811 mysql.sock pear php-fcgi.sock |
4、定期任务计划
|

2
|
[root@plinuxos tmp]# crontab -e
0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh
|
5、清理过期日志
|
1
2
|
[root@plinuxos tmp]# find /tmp/ -name *.log-* -type f -mtime +10 |xagrs rm
##也可以放在脚本里，定期清除 |
静态文件不记录日志和过期时间
1、编辑配置文件

access_log /tmp/default.log log001;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
