部署Linux系统前端服务(Nginx负载均衡),前后端调试

全部任务流程图

 1.编辑hosts文件(实现本机的ip与域名映射)

如果在本机进行业务测试. 则windows/Linux系统,提供了一个测试的文件.在该文件中可以编辑域名与IP的映射关系. 但是只对本机有效. 该文件就是hosts文件.

C:\Windows\System32\drivers\etc\hosts

127.0.0.1       localhost
::1             localhost
#图片服务器域名
#127.0.0.1       image.jt.com
#前端域名地址
#127.0.0.1       web.jt.com
#后端域名地址
#127.0.0.1       manage.jt.com

#Linux系统配置 只对本机测试有效
192.168.126.129       image.jt.com
192.168.126.129       web.jt.com
192.168.126.129       manage.jt.com

2.Linux安装Nginx

下载地址

URL:http://nginx.org/en/download.html 

 上传压缩包

上传到指定目录中 /usr/local/src 

操作安装包-Nginx数据源 

解压:tar -xvf nginx补全名称

删除压缩包 rm -f nginx补全名称

重名称文件:  mv nginx-1.19.4   nginx-source 

3.安装nginx服务器

*说明:在nginx-source的根目录中执行如下命令
需要提前安装nginx的依赖项* 

 yum -y install gcc pcre-devel zlib-devel openssl openssl-devel

 ./configure

 执行make

 执行make install

 查找Nginx真实文件地址:whereis nginx 

nginx命令

1.启动命令: ./nginx
2.重启命令: ./nginx -s reload
3.关闭命令: ./nginx -s stop 

配置Nginx配置文件(/usr/local/nginx/conf)

		location / {
			#proxy_pass 反向代理服务器发起是一个http请求
			proxy_pass  http://tomcats;

	#配置图片反向代理  image.jt.com 
	server {
		listen 80;
		server_name image.jt.com;
		location / {
			root /usr/local/src/images;
		} 
	}
	
}

 4.打包前端代码

修改前端对后台axios访问地址 

 修改图片上传访问axios访问地址 

前端打包

vue脚手架中build生成dist静态资源

说明: 将前端打包好的目录dist 上传到指定的位置 /usr/local/nginx 目录下, 如图所示; 

切记重启Nginx!!!!!!!!!!!!!!!!!!!!!!!!!!!
