这里使用 nginx负载两个tomcat服务javascript

随着访问量愈来愈大,nginx的日志文件会不断增大,会致使日志写入时间增长,因此定时备份切割日志文件是必须的,这里写一个windows下定时将日志文件备份状况的命令行:css
@echo off echo 备份日志文件 #取到当前全部日志文件数量 for /f %%i in ('dir *.log /b/a-d') do set /a num+=1 #备份日志文件 copy access.log access%num%.log #将一个空日志文件覆盖原来的日志文件 copy /y accessnull.log access.log echo ... echo ... echo 备份完成! #pause
