HTTP模块
Nginx源码目录中在src/http中
客户端请求到Nginx中时，HTTP在Nginx中的执行流程可以分为11执行阶段，这个是在ngx_http_core_module.h中已经事先定义好的
typedef enum {
NGX_HTTP_POST_READ_PHASE = 0,
NGX_HTTP_SERVER_REWRITE_PHASE,
NGX_HTTP_FIND_CONFIG_PHASE,
NGX_HTTP_REWRITE_PHASE,
NGX_HTTP_POST_REWRITE_PHASE,
NGX_HTTP_PREACCESS_PHASE,
NGX_HTTP_ACCESS_PHASE,
NGX_HTTP_POST_ACCESS_PHASE,
NGX_HTTP_PRECONTENT_PHASE,
NGX_HTTP_CONTENT_PHASE,
NGX_HTTP_LOG_PHASE
} ngx_http_phases;
一个配置块的示例
main
http {
upstream { ... }
split_clients { ... }
map { ... }
geo { ... }
server {
if (){ ... }
location / {
limit_except { ... }
}
}
}
相应的参数要放到对应的指令块中，不然Nginx语法不能通过，检测Nginx配置的命令./nginx/sbin/nginx -t
server指令块的设置
Syntax: server { ... }
Default: —
Context: http #只在http指令块中生效
