twemproxy分布式中间件：


安装：
yum install automake  libtool -y
git clone git://github.com/twitter/twemproxy.git 
cd twemproxy 
autoreconf -fvi 
./configure --enable-debug=log 
make 
src/nutcracker -h 


3．配置
cp ./conf/nutcracker.yml /etc/




[root@virtdb54 soft]# more /etc/nutcracker.yml 
alpha:
  listen: 192.168.2.54:22121
  hash: fnv1a_64
  distribution: ketama
  auto_eject_hosts: true
  redis: true
  server_retry_timeout: 2000
  server_failure_limit: 1
  servers:
   - 192.168.2.61:6002:1
   - 192.168.2.61:6001:1


   




keys是直接由host:port:weight




运行：
/soft/twemproxy/src/nutcracker -d -c /etc/nutcracker.yml -o /tmp/tw.log
ps aux | grep nutcracker




测试：
[root@virtdb54 soft]# more redistw.py 
import redis




re = redis.StrictRedis(host='192.168.2.54', port=22121, db=0)




for i in range(10000,30000):
    key = str(i)
    value = 'id' + str(i)
    re.set(key,value)
    result = re.get(key)
    print result








统计redis中所有的KEY
echo "keys * "  |redis-cli -h 192.168.2.61 -p 6001 |wc -l
echo "keys * "  |redis-cli -h 192.168.2.61 -p 6002 |wc -l






查看命令率：
echo "info"  |redis-cli -h 192.168.2.61 -p 6001 |grep hit |awk -F ":" '{print $2}'
echo "info"  |redis-cli -h 192.168.2.61 -p 6002 |grep hit |awk -F ":" '{print $2}'
