Linux timed cut Nginx access logs and delete log records before a specified number of days

Description

Operating system: CentOS

Site 1:bbs. 111cn.net

Site 2:sns. 111cn.net

Nginx Installation path:/usr/local/nginx

Nginx configuration file path:/usr/local/nginx/conf/nginx.conf

Site 1 configuration file path:/usr/local/nginx/conf/vhost/bbs.111cn.net.conf

Site 2 configuration file path:/usr/local/nginx/conf/vhost/sns.111cn.net.conf

Objective:

1, the site 1 and site 2 of the Nginx access log saved by day, log path is:

Site 1:/usr/local/nginx/logs/nginx_logs/bbs_logs

Site 2:/usr/local/nginx/logs/nginx_logs/sns_logs

2, only 30 days to keep the log records

Specific actions:

1. Create Log Store path

Mkdir-p/usr/local/nginx/logs/nginx_logs/bbs_logs

Mkdir-p/usr/local/nginx/logs/nginx_logs/sns_logs

2, set nginx logging format

vi/usr/local/nginx/conf/nginx.conf #编辑

Log_format Main ' $remote _addr-$remote _user [$time _local] ' $request '

' $status $body _bytes_sent ' $http _referer '

' $http _user_agent ', ' $http _x_forwarded_for ';

Cancel the comment in front of the logging format and add a row at the end, as follows:

Log_format Main ' $remote _addr-$remote _user [$time _local] ' $request '

' $status $body _bytes_sent ' $http _referer '

"$http _user_agent" "$http _x_forwarded_for"

' $http _host $upstream _status $upstream _addr $request _time $upstream _response_time '; #新添加的一行

: wq! #保存退出

3, set up the virtual host configuration file

Vi/usr/local/nginx/conf/vhost/bbs.111cn.net.conf #编辑, in bbs.111cn.net; Add below this line

Access_log Logs/bbs_access.log Main; #注意这里的main要和上一步中的main一致

: wq! #保存退出

Vi/usr/local/nginx/conf/vhost/sns.111cn.net.conf #编辑, in sns.111cn.net; Add below this line

Access_log Logs/sns_access.log Main; #注意这里的main is consistent with main in the previous step

: wq! #保存退出

4. Create Nginx Log Cutting script

vi/home/crontab/cut_nginx_log.sh #编辑

#!/bin/sh

Logs_path= "/usr/local/nginx/logs/"

Days=30

MV ${logs_path}bbs_access.log ${logs_path}nginx_logs/bbs_logs/bbs_access_$ (date-d "Yesterday" + "%Y%m%d"). Log

MV ${logs_path}sns_access.log ${logs_path}nginx_logs/sns_logs/sns_access_$ (date-d "Yesterday" + "%Y%m%d"). Log

KILL-USR1 ' Cat/usr/local/nginx/logs/nginx.pid '

Find ${logs_path}nginx_logs/bbs_logs/-name "bbs_access_*"-type f-mtime + $DAYS-exec rm {};

Find ${logs_path}nginx_logs/sns_logs/-name "sns_access_*"-type f-mtime + $DAYS-exec rm {};

: wq! #保存退出

chmod +x/home/crontab/cut_nginx_log.sh #添加脚本执行权限

5, add Task plan, modify/etc/crontab

Vi/etc/crontab #在最后一行添加

0 0 * * * root/home/crontab/cut_nginx_log.sh #表示每天凌晨执行

: wq! #保存退出

6, restart Crond to make the settings effective

/etc/rc.d/init.d/crond Restart #yum install-y vixie-cron installation Scheduled Tasks, some systems may not have pre-installed

Chkconfig Crond on #设为开机启动

Service Crond start #启动

every day will be in /usr/local/nginx/logs/nginx_logs/bbs_logs and /usr/local/nginx/logs/nginx_logs/sns_logs

The directory generates a similar Bbs_access_20140126.log and Bbs_access_20140126.log the log file

And only keep the log records for the last 30 days

At this point, Linux under the scheduled cutting Nginx access log and delete the specified number of days before the completion of the log record.
