server模块的作用(每一个server都必定有一个location):
1.类似于在门口等着接待客人的侍者,有多个server就是有多个侍者;配置服务监听信息
2.根据主机信息,确认是哪个侍者接待的客人,根据侍者安排客人的去向
3.最后交给location服务员进行处理
location模块的作用:
1.找UR信息
2.指明去哪找.
3.有指定要找的信息就是指定的信息相应,没有指定找的信息就默认找index.html响应
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000; //定义反向代理
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
注:当LNMP架构分台部署,“/scripts”需换成php的目录
