【商城项目专栏一】Nginx

 

域名解析

    先在本地host解析，解析失败去域名服务器解析，将域名解析成对应的IP，域名备案就是域名绑定IP的过程

Nginx反向代理

    正向代理：配置客户机，将请求代理到一个服务器

    反向代理：客户端请求Nginx，Nginx将请求转发到服务器【客户端不用做任何修改】

    NGINX上配置域名解析，监听80端口【根据域名转发】

本地配置host文件，域名解析

C:\Windows\System32\drivers\etc

添加：

192.168.146.129 manage.leyou.com
192.168.146.129 www.leyou.com
192.168.146.129 api.leyou.com
192.168.146.129 image.leyou.com

虚拟机安装

    1、上传nginx安装包，解压【上传软件：xftp】

上传路径/home/leyou

解压命令：tar xvf nginx   【按table键自动补齐】

删除安装包：rm -rf 。。。

如果XFTP连接不上，换SFTP协议

    2、进入nginx目录执行以下命令   

cd /home/leyou/nginx-1.17.5

指定安装目录在/opt/nginx：./configure --prefix=/opt/nginx --sbin-path=/usr/bin/nginx

编译安装：make && make install

启动：nginx

停止：nginx -s stop

重新加载：nginx -s reload

查看配置文件地址：nginx -t

报错：

解决办法：https://blog.youkuaiyun.com/hybaym/article/details/50929958

yum install -y gcc-c++

yum install -y pcre-devel

yum install -y zlib-devel

然后关闭防火墙，以下是关防火墙碰到的问题

设置防火墙关闭：chkconfig iptables off 然后重启配置【centos7用下面的命令】

临时关闭防火墙：service iptables stop

CentOS之service iptables stop 显示not loaded :https://blog.youkuaiyun.com/yelllowcong/article/details/75945339

    3、修改配置文件/opt/nginx/nginx.config
