這是失敗的webview設定檔，是使用nginx rotatelog的設定檔改出來的
在/var/log/nginx資料夾階層裡面是有正常的每天切log
在底下資料夾webview卻沒有生效

設定檔：
/var/log/nginx/webview/*log {
create 0644 nginx nginx
daily
dateext
rotate 10
missingok

notifempty

nocompress
sharedscripts
postrotate
    /bin/kill -USR1 `cat /run/nginx.pid 2>/dev/null` 2>/dev/null || true
endscript

}
