利用cronolog对nginx日志进行分割

一、cronolog安装

wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
tar zxvf cronolog-1.6.2.tar.gz

cd cronolog-1.6.2

./configure

make

make install

二、nginx日志配置

log_format access '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" $http_x_forwarded_for';

server

{

listen 80;

server_name xxx.xxx.xxx.xxx;

root /data/sq/install_package/;

access_log /home/test/workspace/nginx/logs/access.log;

}



三、先创建一个命名管道

mkfifo /home/test/workspace/nginx/logs/access.log



四、配置cronolog：

mkfifo /home/test/workspace/nginx/logs/access.log

按小时分割

nohup cat /home/test/workspace/nginx/logs/access.log | /usr/sbin/cronolog /home/test/workspace/nginx/logs/access_%Y-%m-%d-%H.log &

按分钟分割

nohup cat /home/test/workspace/nginx/logs/access.log | /usr/sbin/cronolog /home/test/workspace/nginx/logs/access_%Y-%m-%d-%H-%M.log &

按天分割

nohup cat /home/test/workspace/nginx/logs/access.log | /usr/local/sbin/cronolog /home/test/workspace/nginx/logs/access_%Y-%m-%d.log &

按每天一个目录分割

nohup cat /home/test/workspace/nginx/logs/access.log | /usr/sbin/cronolog /home/test/workspace/nginx/logs/%Y-%m-%d/access_.log &

五、启动Nginx

/usr/local/nginx/sbin/nginx

注意： cronolog必须在nginx启动前启动。如果nginx先启动了，可以reload实现
