1.安装nginx包

sudo apt update
sudo apt install nginx

2.安装完成后系统自动启动nginx

sudo systemctl status nginx

查看nginx服务的状态

3.开启防火墙上的HTTP服务端口80

sudo ufw allow ‘Nginx HTTP’

4.在浏览器输入 http://localhost 看到nginx的欢迎界面，代表成功

在这里插入图片描述

5.更改nginx的配置文件

cd /etc/nginx/
sudo gedit nginx.conf

更改nginx.conf配置文件，在http{}内添加如下内容，修改如下：

server{
        listen       8090;#80
        server_name  localhost;
location ~ .*\.(gif|jpg|jpeg|png)$ {  
                #expires 24h;  
                
                root /home/wqh/savingImages/20230816/;#指定图片存放路径  
                autoindex on;
                #access_log /njbestway/server/logs/images.log;#日志存放路径  
                proxy_store on;  
                proxy_store_access user:rw group:rw all:rw;  
                proxy_temp_path     /home/wqh/savingImages/20230816/;#图片访问路径  
                proxy_redirect     off;  
                proxy_set_header    Host 127.0.0.1;  
                client_max_body_size  10m;  
                client_body_buffer_size 1280k;  
                proxy_connect_timeout  900;  
                proxy_send_timeout   900;  
                proxy_read_timeout   900;  
                proxy_buffer_size    40k;  
                proxy_buffers      40 320k;  
                proxy_busy_buffers_size 640k;  
                proxy_temp_file_write_size 640k;  
                if ( !-e $request_filename)  
                {  
                 proxy_pass http://127.0.0.1;#默认80端口  
                }  
        }
