备份docker内nginx日志（可能会丢少量日志）

 编辑脚本 nginx_log_bak.sh ：

y=`date -d '-1 hour' +%Y`
m=`date -d '-1 hour' +%m`
d=`date -d '-1 hour' +%d`
h=`date -d '-1 hour' +%H`

path=$y/$m/$d
name=${y}_${m}_${d}_${h}

cd /data/nginx/logs
mkdir $y
mkdir $y/$m
mkdir $y/$m/$d

cd /data/nginx/logs
cat access_api.log > $path/access_api_$name.log
>/data/nginx/logs/access_api.log
cd $path
tar -czvf access_api_$name.log.tar.gz access_api_$name.log
rm access_api_$name.log
echo access_api_$name.log.tar.gz

cd /data/nginx/logs
cat access.log > $path/access_$name.log
>/data/nginx/logs/access.log
cd $path/
tar -czvf access_$name.log.tar.gz access_$name.log
rm access_$name.log
echo access_$name.log.tar.gz
