方式一:
nginx cronolog日志分割配置文档,根据下面方法,每分钟分割一次NGINX访问日志。

<span>1</span>.nginx日志配置
 access_log access_log /data/access_log_pipe main;
<span>2</span>.先创建一个命名管道
mkfifo /www/<span>log</span>/access_log_pipe
<span>3</span>.配置cronolog:
nohup cat /data/access_log_pipe | <span>/usr/local</span><span>/sbin/cronolog</span> /data/<span>log</span>/domain.access<span>_</span><span>%Y</span><span>%m</span><span>%d</span><span>%H</span><span>%M</span>.<span>log</span> &
<span>4</span>.启动Nginx
/usr/<span>local</span>/nginx/sbin/nginx

注意:
cronolog必须在nginx启动前启动
没有安装cronolog的话,需要先安装
wget http:<span>//cronolog</span>.org/download/cronolog-<span>1.6</span>.<span>2</span>.tar.gz
tar zxvf cronolog-<span>1.6</span>.<span>2</span>.tar.gz
cd cronolog-<span>1.6</span>.<span>2</span>
.<span>/configure
 make
make install
方式二:

定时任务中每小时添加定时任务,执行一下脚本,可以实现小时日志分割
log_dir="/var</span><span>/log/nginx</span><span>"
date_dir=`date +<span>%Y</span>/<span>%m</span>/<span>%d</span>/<span>%H</span>`
/bin/mkdir -p <span>${log_dir}</span>/<span>${date_dir}</span> > /dev/null 2>&1
/bin/mv <span>${log_dir}</span>/access.log   <span>${log_dir}</span>/<span>${date_dir}</span>/access.log
kill -USR1 `cat /opt/nginx/logs/nginx.pid`

方式三:
使用logrotate做nginx日志轮询
logrotate看名字就知道是专门做日志轮询的,只把任务配置放在/etc/logrotate.d/下,任务就会自动完成,而且无需安装,系统自带,比较推荐使用.
vi /etc/logrotate.d/nginx  

    /usr/local/nginx/logs/www.willko.cn.log /usr/local/nginx/logs/nginx_error.log {
    notifempty
    daily
    sharedscripts
    postrotate
    /bin/kill -USR1 `/bin/cat /usr/local/nginx/nginx.pid`
    endscript
    } 

多个日志以空格分开,
notifempty 如果日志为空则不做轮询
daily 每天执行一次
postrotate 日志轮询后执行的脚本
这样,每天都会自动轮询,生成nginx.log.1-n
 后话:

用Jmeter对方法一进行了测试,新建线程组:线程数200,循环150,新建http请求,请求nginx上的图片,请求30000次,失败326次,后台形成5个文件,行数如下:

   2868 access_201112182030.log
   7777 access_201112182031.log
   7626 access_201112182032.log
   7873 access_201112182033.log
   3530 access_201112182034.log
  29674 total

并没有因为切分文件而丢失日志。</span>
Copy after login

The above introduces the common log splitting methods of Nginx, including nginx content. I hope it will be helpful to friends who are interested in PHP tutorials.
