redis 脚本扫描

1.创建脚本

vi scan\_get\_all\_keys.sh

\#!/bin/bash

redisbase='/usr/local/bin'

\#\#定义使用说明  
usage()\{  
echo -e "\\033\[31m脚本功能:\\033\[0m"  
echo -e " 用于扫描redis实例中所有的key"  
echo -e " "  
echo -e "\\033\[31m示例如下:\\033\[0m"  
echo -e " sh scan\_get\_all\_keys.sh redis\_node\_6577 6577 0 1000 'match \*MP001\_1'"  
echo -e " "  
echo -e "\\033\[31m注意事项:\\033\[0m"  
echo -e " 1. 只能用于redis 2.8及以上版本,因为只有这些版本支持scan命令"  
echo -e " 2. 第三个参数表示每次scan的key个数,不要超过300"  
\}

\#\#参数判断  
if \[ "$1"x = x \] || (\[ -n "$1" \] && \[ "$2"x = x \] )  
then  
usage  
exit  
fi

i=0

host=$1  
port=$2  
db=$3  
num=$4  
\#matchpattern为需要模糊匹配的表达式参数  
matchpattern=$5

tmp\_file=$\{host\}\_$\{port\}\_tmp.txt  
result\_file=$\{host\}\_$\{port\}.txt  
rm -rf $\{result\_file\} >> /dev/null  
touch $\{result\_file\} >> /dev/null

if \[ 1 \]  
then  
$\{redisbase\}/redis-cli -h $host -p $port -n $\{db\} scan $\{i\} $\{matchpattern\} count $num > $\{tmp\_file\}  
i=\`head -1 $\{tmp\_file\}\`  
counts\_tmp=\`cat $\{tmp\_file\}|wc -l\`  
counts=$(( $counts\_tmp - 1 ))  
tail -$\{counts\} $\{tmp\_file\} >> $\{result\_file\}  
fi  
while \[ $i -ne 0 \]  
do  
$\{redisbase\}/redis-cli -h $host -p $port -n $\{db\} scan $\{i\} $\{matchpattern\} count $num > $\{tmp\_file\}  
i=\`head -1 $\{tmp\_file\}\`  
counts\_tmp=\`cat $\{tmp\_file\}|wc -l\`  
counts=$(( $counts\_tmp - 1 ))  
tail -$\{counts\} $\{tmp\_file\} >> $\{result\_file\}  
done  
rm -rf $tmp\_file  
sed '/^$/d' $\{result\_file\} > final\_$\{result\_file\}

2.执行脚本

\---放在空目录下执行

sudo sh scan\_get\_all\_keys.sh 10.1.1.1 6379 8 300 'match plus-gat:REQ\_IP\_LIMITED\_\*'

redis IP:10.1.1.1  
端口：6379  
库序列号：8  
keys 个数：300  
like 扫描：'match like 那部分\*'
