注：mode一般写在backend段，也可以写在defaults,forntend段
注：maxconn写在defaluts或forntend段表示前端的最大连接，写在backend表示后端server的最大连接

注：forentend有两种写法
第一种写法：定义多个frontend,基于虚拟IP进行绑定frontend，即访问不同的IP分发到不同的backend，此种写法的缺点是当需要做acl，自定义日志格式时，需要在每个frontend中都写一遍；优点是每个forntend的日志可以写到单独的文件中
第二种写法：定义1个frontend,基于acl定义规则，根据请求的域名来分发到不同的backend，此种写法的优点是当需要定义acl或者自定义日志格式时，只需要在frontend中写一遍即可；缺点是访问所有backend的日志都只能写到一个文件中，在分析日志时会给造成麻烦
以上两种写法，可以根据需求进行选择！！！
