几个常用命令

start nginx #启动nginx
nginx -s quit #关闭nginx  慢慢关闭？
nginx -s stop #停止nginx 跟关闭类似，直接关闭？
nginx -s reload #修改了配置文件重新加载

定时切割nginx访问日志文件

@echo off
echo 备份日志文件
#取到当前所有日志文件数量
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
