日志自定义
log_format main '$remote_addr ($http_x_forwarded_for) - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" '
'Proxy to: $upstream_addr [$upstream_response_time] [$request_time]';
access_log /log/nginx/access.log main;
error_log /log/nginx/error.log error;
自定义日志输出格式和位置。
作为反向代理时，要在头部使用 X-Forwarded-For 传真实IP。

mv ${LOG_PATH}/error.log ${LOG_PATH}/${DATE_FLAG}_error.log

kill -USR1 $(cat ${NGINXPID})
kill -USR1向nginx进程发送重新打开日志文件的信号。
