shell> make install
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 - 172.18.3.12:11211:1 #- 172.18.3.4:11211:1 #- 172.18.3.7:11211:1 EOF
4. 启动服务
shell> vi /etc/sysconfig/iptables 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
