在我们进行自动发现的时候，总会有一个脚本来获取端口等信息，并返回json格式，那以redis为例，下边是redis进行进行自动发现的脚本

redisport=(`ps aux|grep -w redis-server|grep -v "grep" |awk -F':' '{print $NF}'`)
portnum=${#redisport[@]}

count=`hostname | grep "\-SQ" | wc -l`
if [ $count -eq 1  ];then
address=` /usr/sbin/ip address | grep -w  "inet" | awk -F " " '{print $2}' | egrep "^10."| awk -F"/" '{print $1}'`
else
address=` /usr/sbin/ip address | grep "192.168" | awk '{print $2}' | awk -F "/" '{print $1}'`
fi

printf "{\n"
printf  '\t'"\"data\":["
for ((i=0;i<$portnum;i++))
do
        printf '\n\t\t{\n'
        printf '\t\t\t'
        printf "\"{#REDIS_PORT}\":\"${redisport[$i]}\"",
        printf '\n\t\t\t'
        printf "\"{#REDIS_ADDRESS}\":\"${address}"\",
        printf '\n\t\t\t'
        printf "\"{#REDIS_NAME}\":\"Redis ${address}:${redisport[$i]}\""
        printf '\n\t\t}'
        if [ $i -lt $[$portnum-1] ];then
                printf ','
        fi
done
printf  "\n\t]\n"
printf "}\n"

返回结果如下

        "data":[
                {
                        "{#REDIS_PORT}":"6386",
