我把nginx的access.log删除了以后重新vim一个access.log可不写入了，怎么办？

restart或者reload nginx就可以了吧

#!/bin/bash
 
NHOME=/nginx
LOGHOME=$NHOME/logs
PIDFILE=$LOGHOME/nginx.pid
NGXPID=$(cat $PIDFILE)
NGXCONF=$NHOME/conf/nginx.conf
RDATE=$(date +%y%m%d%H%M%S)
 
if [[ ! -f $PIDFILE ]]
     then
        echo "$PIDFILE not found."
        exit
fi
 
if [[ ! -f $NGXCONF ]]
     then
        echo "$NGXCONF not found."
        exit
fi
 
LOGNA1=$(grep -e "^\s*[^#]*\s*access_log" $NGXCONF|sed -n 's/;//p'|awk '!/\<on\>|\<off\>/ {print $2}'|sed -n '1p')
LOGNA2=$(echo $LOGNA1 |sed -n '/^\//p')
if [[ -z $LOGNA1 ]]
        then
            echo "access_log path not found."
            exit
fi
 
if [[ -z $LOGNA2 ]]
   then
            mv $NHOME/$LOGNA1 $NHOME/$(dirname $LOGNA1)/access_${RDATE}.log
            kill -USR1 $NGXPID
            cd $NHOME/$(dirname $LOGNA1)
            gzip access_${RDATE}.log
   else
            mv $LOGNA2 $(dirname $LOGNA2)/access_${RDATE}.log
            kill -USR1 $NGXPID
            cd $(dirname $LOGNA2)
            gzip access_${RDATE}.log
fi
 
cd $NHOME/$(dirname $LOGNA1)
find ./ -iname "access_*.log.gz" -mtime +90 -type f -exec rm -f {} \;
 
exit 0;
