Redis view client connection

It is easier to view the client connection for a single instance

client list

Now I have several physical machines in my hand , Each physical machine is deployed 100 An example , Because it is an example left over from the past , I don't know if I can get offline , I want to know whether these machines are used ？

If you want to know if anyone uses , Just connect it to see if there is a client connection ;

Now the problem is that the system is deployed 70 More than one instance , The password of each instance is different ; You can't connect each instance through ports one by one , And try the password one by one ;

First, get all port

ps -ef | grep redis | awk -F: '{print $NF}' > port.list

Get all passwords

grep pass */*.conf | awk '{print $NF}' | sort | uniq > auth.list

Loop through each password and port , Try to connect , And get connection information

#!/bin/bash


for auth in `cat auth.list`
do
        #echo $x;
        for port in `cat port.list`
        do 
                #echo $x;
                echo client list |  /export/Data/redis/bin/redis-cli -h 127.0.0.1 -p $port -a $auth
        done 
done
