logrotate切割nginx日志

• 首先安装logrotate日志切割工具

yum -y install logrotate

• vim /etc/logrotate.d/nginx
• 在/etc/logrotate.d目录下创建一个nginx的配置文件"nginx"配置内容如下,里面的路径根据自己项目的实际情况配置

/opt/wisecloud/cloudstorage/cs_resty/software/cs_resty/logs/*.log {
daily
rotate 5
missingok
notifempty
create 0664 root utmp
olddir /opt/wisecloud/cloudstorage/cs_resty/software/cs_resty/logs/history_log
sharedscripts
postrotate
    if [ -f /opt/wisecloud/cloudstorage/cs_resty/software/cs_resty/logs/nginx.pid ]; then
        kill -USR1 `cat /opt/wisecloud/cloudstorage/cs_resty/software/cs_resty/logs/nginx.pid`
    fi
endscript
}

• 让logrotate每天进行一次滚动,在crontab中添加一行定时脚本

crontab -e
59 23 * * *  /usr/sbin/logrotate -f /etc/logrotate.d/nginx_log

每天23点59分进行日志滚动
