#创建备份目录  如2020/03
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
#将日志移动到上面的目录中
mv ${logPath}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
mv ${logPath}error.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/error_$(date -d "yesterday" +"%Y%m%d").log
#主要用到nginx的-usr1信号，usr1 : reopen the log files 向nginx主进程发送信号以重新打开日志
kill -USR1 `cat ${logs_path}nginx.pid`

mkdir historyLog
