代理和反向代理概念
反向代理的作用
①保护网站安全:任何来自Internet的请求都必须先经过代理服务器;
②通过配置缓存功能加速Web请求:可以缓存真实Web服务器上的某些静态资源,减轻真实Web服务器的负载压力;
③实现负载均衡:充当负载均衡服务器均衡地分发请求,平衡集群中各个服务器的负载压力;
之前在mac环境下 使用brew install nginx安装了nginx
配置的端口号为8282
开启后测试如下,
mac下 nginx配置文件 /usr/local/etc/nginx/nginx.conf
vi /usr/local/etc/nginx/nginx.conf修改配置文件

mamp 开启nginx服务
http://tp5.test.com:7888/index/goodsclass/classlist
失败了 配置可能有问题,还要再看一下 ,由于工作,,接下来在优化,再来看是怎么回事
今天接着来解决问题,尝试着将代理写一个其他的连接 比如反向代理服务器设置为:
server {
listen 8282;
server_name localhost;#这里也可以填写自己的域名 或者服务器地址 比如104.224.166.36
#charset koi8-r;
#access_log logs/host.access.log main;
# Load configuration files for the default server block.
#include /etc/nginx/default.d/*.conf;
location / {
proxy_pass https://blog.csdn.net/resilient;
}
重启nginx,执行命令nginx -s relaod
访问 localhost:8282
居然出现了界面,说明代理过去了,那么我tp5项目咋就代理不过去 呢
再次来看,修改配置文件
server {
listen 8282;
server_name localhost;#这里也可以填写自己的域名 或者服务器地址 比如104.224.166.36
#charset koi8-r;
#access_log logs/host.access.log main;
# Load configuration files for the default server block.
#include /etc/nginx/default.d/*.conf;
location / {
proxy_pass http://tp5.test.com:7888/;
}
http://localhost:8282/index/goodsclass/classlist
运行其他页面也可以访问
http://tp5.test.com:7888/index/goodsclass/classadd
http://localhost:8282/index/goodsclass/classadd
说明配置好了
一般情况下 还可以做图片啊文件之类的缓存,打开这些配置就可以座缓存
