CentOs7 配置Nginx 部署Java前后端项目https协议

# 下载Nginx 
wget http://nginx.org/download/nginx-1.19.6.tar.gz
# 解压
tar -xzf nginx-1.19.6.tar.gz 
# 切换到目录下
cd nginx-1.19.6

2.安装nginx的依赖环境

# yum升级
yum update
# yum安装依赖
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
# 配置ssl模块
./configure
./configure --with-http_ssl_module
# 安装
make & make install
# 查看是否安装成功
/usr/local/nginx/sbin/nginx -V

3.配置Nginx

# 切换到Nginx配置文件目录下
cd /usr/local/nginx/conf
# 修改配置文件
vi nginx.conf

Nginx的配置文件（https协议）

有几点注意项：

1.location /backend/ 代理的是后端， location /代理的是前端
2.backend 得在后台程序中的application.yml中定义
3.启动项目之后，开启了防火墙的话，一定要开放443、80和项目中的端口号

4.前端访问后端的地址得是VUE_APP_BASE_API = 'https://192.168.3.105/backend'，https协议的，不然会出现协议混淆，访问不到后端接口。

server {
    
    
        listen 443 ssl;
		server_name  localhost;

        ssl_certificate      /usr/local/nginx/cer/server.crt;
        ssl_certificate_key  /usr/local/nginx/cer/server.key;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

		location / {
    
    
            root   /usr/local/nginx/html/dist;
			try_files $uri $uri/ /index.html;
            index  index.html index.htm;
        }
		
		location /backend/{
    
    
			proxy_set_header Host $http_host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header REMOTE-HOST $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_pass http://localhost:8991;
		}
		
		error_page   500 502 503 504  /50x.html;
        location = /50x.html {
    
    
            root   html;
        }
    }

配置完之后，就启动Nginx

# 切换到sbin目录下
/usr/local/nginx/sbin
# 启动Nginx
./nginx 
# 改动配置之后重启
./nginx -s reload
