Apache Traffic Server配置cluster服务

关于TrafficServer Cluster原理可以查阅http://blog.chinaunix.net/uid-10249062-id-3243299.html，这篇博文已经描述的非常清晰

1、修改records.config配置

配置cluster模式

LOCAL proxy.local.cluster.type INT 1    默认是3

配置cluster 监听端口，默认为8086

CONFIG proxy.config.cluster.cluster_port INT 8086

配置cluster监听网卡，默认为eth0

CONFIG proxy.config.cluster.ethernet_interface STRING eth0   

配置cluster线程数，默认为1，配置线程数以cpu核数作为参考

CONFIG proxy.config.cluster.threads INT 4
