在服務(wù)器上用shell語(yǔ)言+crontab完成對(duì)mongo庫(kù)的定時(shí)備份和清除
1. /www/tools/目錄下的mongo.sh(備份功能)
#!/bin/bash
targetpath="/data/backup/mongo/"
nowtime=$(date +%y%m%d)
start()
{
mongodump -h (mongo庫(kù)的地址) -o ${targetpath}/${nowtime}
}
execute()
{
start
if [ $? -eq 0 ]
then
echo "back successfully!"
else
echo "back failure!"
fi
}
if [ ! -d "${targetpath}/${nowtime}/" ]
then
mkdir ${targetpath}/${nowtime}
fi
execute
echo "============== back end ${nowtime} =============="
2. ?/www/tools/目錄下的delmongo.sh(清除功能)
#!/bin/bash
targetpath='/data/backup/mongo/'
nowtime=$(date -d '-3 days' "+%y%m%d")
if [ -d "${targetpath}/${nowtime}/" ]
then
rm -rf "${targetpath}/${nowtime}/"
echo "=======${targetpath}/${nowtime}/===刪除完畢=="
fi
echo "===$nowtime ==="
3. 添加crontab
20 1 * * * cd /www/tools;/bin/bash /www/tools/mongo.sh
20 1 * * * cd /www/tools;/bin/bash /www/tools/delmongo.sh
