##upstream backend 位置放错了, upstream位置应该放在http模块里面 但必须是在server模块的外面

查找顺序和优先级
1：带有“=“的精确匹配优先
2：没有修饰符的精确匹配
3：正则表达式按照他们在配置文件中定义的顺序
4：带有“^~”修饰符的，开头匹配
5：带有“~” 或“~*” 修饰符的，如果正则表达式与URI匹配
6：没有修饰符的，如果指定字符串与URI开头匹配


Location区段匹配示例location = / {
　　# 只匹配 / 的查询.
　　[ configuration A ]
}
location / {
　　# 匹配任何以 / 开始的查询，但是正则表达式与一些较长的字符串将被首先匹配。
　　[ configuration B ]
}
location ^~ /images/ {
　　# 匹配任何以 /images/ 开始的查询并且停止搜索，不检查正则表达式。
　　[ configuration C ]
}
location ~* .(gif|jpg|jpeg)$ {
　　# 匹配任何以gif, jpg, or jpeg结尾的文件，但是所有 /images/ 目录的请求将在Configuration C中处
　　理。
　　[ configuration D ]
} 各
请求的处理如下例：
