3.增加配置文件

shell> cd /usr/local/twemproxy

shell> cat > /usr/local/twemproxy/nutcracker.yml << EOF

memcache:

  listen: 0.0.0.0:11210

  hash: fnv1a_64

  distribution: ketama

  auto_eject_hosts: true

  redis: false

  timeout: 400

  server_retry_timeout: 30000

  server_failure_limit: 5

  servers:

   - 172.18.18.52:11211:1

   - 172.18.18.53:11211:1

   - 127.18.3.11:11211:1

shell> -A INPUT -m state --state NEW -m tcp -p tcp  --dport 11210 -j ACCEPT #开放防火墙端口11210

shell> /etc/init.d/iptables restart

shell> nutcracker -t #测试配置文件

shell> /usr/local/twemproxy/sbin/nutcracker -d -c /usr/local/twemproxy/nutcracker.yml #指定配置文件启动

5.启动命令详解
