1、當(dāng)硬盤(pán)空間不足15%時(shí)，循環(huán)刪除最早的日志文件(ELK)：
1 2 3 4 5 6 7 8 9 10 | #!/bin/bash
for((i=20;i>=5;i-=1))
do
code=`df /dev/mapper/ElkGroup-lv_elk | grep -c -E \(8[5-9]\%\)\|\(100\%\)`
day=`date -d -"$i days" +%m.%d`
if [ $code -gt 0 ]
then
curl -XDELETE http://127.0.00.1:9200/*.$day
fi
done
|
2、當(dāng)硬盤(pán)空間小于70%時(shí)，自動(dòng)清理最早的日志文件(Nginx)：
1 2 3 4 5 6 7 8 9 10 11 | #!/bin/bash
for((i=42;i>=7;i-=1))
do
code=`df /dev/vdb | grep -c -E \([789][0-9]\%\)\|\(100\%\)`
day=`date -d -"$i days" +%Y-%m-%d`
if [ $code -gt 0 ]
then
rm -rf /home/nginx/*/access_$day.log
rm -rf /home/nginx/*/error_$day.log
fi
done
|
3、讀取Redis表中的值記錄到日志中，并將改值置0
1 2 3 4 5 6 7 8 | #!/bin/bash
for((i=0;i<=1;i+=1))
do
a=(61.189.35.181
59.46.90.82)
echo $(date +%Y%m%d%H%M) $(/usr/local/redis/bin/redis-cli -h 172.16.1.166 -a meTN3xF2yzsbXrRk -n 1 hget ${a[i]} D) >> /usr/local/script/data/${a[i]}.log
/usr/local/redis/bin/redis-cli -h 172.16.1.166 -a meTN3xF2yzsbXrRk -n 1 hset ${a[i]} D 0 > /dev/null 2>&1
done
|
4、刪除同一個(gè)項(xiàng)目舊的文件夾，保留最新的那個(gè)。
1 2 3 4 5 6 7 8 9 10 11 12 | #!/bin/bash
for ((i=5;i>=1;i--))
do
NDPATH="/data/dist/"
PRJ="global-v4.dev"
NUM=`ls -lt $NDPATH | grep "$PRJ-*" | wc -l`
# echo $NUM
if [ $NUM -gt 1 ];then
cd $NDPATH
ls -lt $NDPATH | grep "$PRJ-*" | tail -n 1 | xargs rm -rf
fi
done
|
5、向腳本傳遞參數(shù)：
# ./inputvirible.sh 1 5 9
1 2 3 4 5 | #!/bin/bash
echo "this shell name is : $0"
echo "the first varible is $1"
echo "the second varible is $2"
echo "the third varible is $3"
|
[THE END]
