笔记_Nginx日志切割，_nginx日志切割

grep生成nginx主配置文件

egrep -v "#|^$" nginx.conf.default >nginx.conf

日志格式

[root@vfast conf]# sed -n '21,23 s/#//gp' nginx.conf.default 
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

具体配置文件如下：

[root@vfast conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '         配置日志格式
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.blog.conf;
location / {
root html/www;
index index.html index.htm;
}
access_log logs/access_www.log main;       以www.blog.com为例，生成相关的日志文件
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

创建根目录

[root@vfast html]# mkdir www

[root@vfast www]# vim index.html
[root@vfast www]# cat index.html
http://www.blog.com

添加hosts解析

[root@vfast www]# vim /etc/hosts
[root@vfast www]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.31.234 www.blog.com

重新加载nginx

[root@vfast www]# /application/nginx/sbin/nginx -s reload

测试

[root@vfast www]# curl www.blog.com
http://www.blog.com

nginx默认会把所有访问日志生成到access_www.log里，做日志轮询切割，方便日志的分析处理，这里使用按天分割的方法

切割脚本如下：cut_nginx_log.sh

#!/bin/bash

Dateformat=`date +%Y%m%d`
Basedir="/application/nginx"
Nginxlogdir="$Basedir/logs"
Logname="access_www"
[ -d $Nginxlogdir ] && cd $Nginxlogdir||exit 1
[ -f ${Logname}.log ]||exit 1
/bin/mv ${Logname}.log ${Logname}_${Dateformat}.log
$Basedir/sbin/nginx -s reload

计划任务实现每天00点整定时执行cut_nginx_log.sh切割日志

00 00 * * * /bin/sh /server/script/cut_nginx_logs.sh >/dev/null 2>&1
