5.重新加载 nginx

nginx -s reload

六、nginx 的配置文件（nginx.conf）

nginx 配置文件有三部分组成

1.全局块

从配置文件开始到 events 块之间的内容，主要会设置一些影响 nginx 服务器整体运行的配置指令。

比如：worker_processes 1; worker_processes 值越大，可以支持的并发处理量也越多。

2.events 块

events 块涉及的指令主要影响 nginx 服务器与用户的网络连接。?比如：worker_connection 1024; 支持的最大连接数。

3.http 块

nginx 服务器配置中最频繁的部分，http 块也可以包括 http 全局块、server 块。

七、nginx 配置图片的访问路径

图片文件上传至服务器 D:/images 中，然后通过 IP 地址/upload/加图片名称进行访问。

#user nobody;worker_processes 1;

#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;

#pid logs/nginx.pid;

events {worker_connections 1024;}

http {include mime.types;default_type application/octet-stream;

#log_format main '$remot{e}_{a}ddr-$remote_user [$tim{e}_{l}ocal]"$request" '

'$status$body_bytes_sent "$http_referer" '

'"$htt{p}_{u}se{r}_{a}gent""$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;#tcp_nopush on;

#keepalive_timeout 0;keepalive_timeout 65;

#gzip on;

server {listen 80;server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

#访问路径拼接 upload 访问本地绝对路径下的某图片 location /upload/ {alias D:/images/;autoindex on;}

location / {root html;index index.html index.htm;}

#error_page 404 /404.html;

redirect server error pages to the static page /50x.html

error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}

proxy the PHP scripts to Apache listening on 127.0.0.1:80

#location ~ .php$ {

proxy_pass http://127.0.0.1;

#}

pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#location ~ .php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

include fastcgi_params;

#}

deny access to .htaccess files, if Apache's document root

concurs with nginx's one

#location ~ /.ht {

deny all;

#}}

another virtual host using mix of IP-, name-, and port-based configuration

#server {

listen 8000;

listen somename:8080;

server_name somename alias another.alias;

location / {

root html;

index index.html index.htm;

}

#}

HTTPS server

#server {

listen 443 ssl;

server_name localhost;

ssl_certificate cert.pem;

ssl_certificate_key cert.key;

ssl_session_cache shared:SSL:1m;

ssl_session_timeout 5m;

ssl_ciphers HIGH:!aNULL:!MD5;

ssl_prefer_server_ciphers on;

location / {

root html;

index index.html index.htm;

}

#}

}

配置好 nginx.conf 记得重启一下服务器。效果如图：

八、java 后台代码

/**

• 文件上传*/@RestControllerpublic class FileController {

@PostMapping(value = "/fileUpload")public String fileUpload(@RequestParam(value = "file") MultipartFile file) {if (file.isEmpty()) {System.out.println("请选择图片");}String fileName = file.getOriginalFilename(); // 文件名 String suffixName = fileName.substring(fileName.lastIndexOf(".")); // 后缀名 String filePath = "D:/images/"; // 上传后的路径 fileName = UUID.randomUUID() + suffixName; // 新文件名 File dest = new
