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"http://www.mamicode.com/" ‘{print $1}‘` else address=` /usr/sbin/ip address | grep "192.168" | awk ‘{print $2}‘ | awk -F "http://www.mamicode.com/" ‘{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", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6386" }, { "{#REDIS_PORT}":"6387", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6387" }, { "{#REDIS_PORT}":"6388", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6388" }, { "{#REDIS_PORT}":"6379", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6379" }, { "{#REDIS_PORT}":"6384", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6384" }, { "{#REDIS_PORT}":"6385", "{#REDIS_ADDRESS}":"192.168.43.66", "{#REDIS_NAME}":"Redis 192.168.43.66:6385" } ] }
