前言:博主已經將自己的vue項目部署在nginx上邊,服務器是阿里雲服務器,今天是要部署springboot後臺並實現前臺請求轉發到後臺,踩了很多坑,記錄一下。
一、服務器環境
- 阿里雲服務器
- jdk1.8
- docker(以下是容器)
- Redis
- Rabbitmq
- mysql8.x
二、服務器配置jdk環境
該步驟請查看:服務器配置jdk1.8環境並永久性運行
三、部署springboot
雙擊package即可進行打包,博主設置的是jar包
生成之後如下
然後我們直接將該jar包往服務器上一丟(隨便找個文件夾,或者自己建一個)
cd 到jar包位置,執行以下命令
$ nohup java -jar 包名.jar >log.txt &
// 這種方法會把日誌文件輸入到你指定的文件中,沒有則會自動創建。並且進程會在後臺運行。
// 不要忘記後邊的 &
我們查看一下端口情況,我的佔用的是8001端口,執行netstat -anp |grep 8001
,看到如下
此時,後臺已經跑起來了,並且有一些tcp連接隨時待命
四、修改Nginx配置
方案一
在沒有設置代理的情況下,客戶端請求到nginx,nginx服務器是不會進行轉發的,接下來我們配置一下,vim /etc/nginx/nginx.conf
或者拷貝到本地修改再上傳
# 核心配置
server {
listen 8080;
server_name xxxxxxx;
# root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
root /dist;
index index.html;
try_files $uri $uri/ /index.html;
}
location /api {
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Methods 'GET, POST, DELETE, PUT, OPTIONS';
add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
if ($request_method = 'OPTIONS') {
return 204;
}
rewrite ^/api/(.*)$ /$1 break;
proxy_pass http://xxxxxxx:8001;
}
}
- 修改完之後,重啓nginx,
nginx -s reload
,如果啓動失敗,報.pid文件的錯,比如:
nginx: [error] open() "/run/nginx.pid" failed (2: No such file or directory)
也就是沒有改文件,我們找到報錯目錄,並在其下新建nginx.pid文件,然後nginx -s stop
關閉服務,然後nginx -c /etc/nginx/nginx.conf
直接以配置文件重啓,注意,nginx.pid所在的路徑必須和配置文件中配置的pid文件路徑一樣,我這裏是/run/nginx.pid
- 然後就可以訪問了
- 當瀏覽器發送ip+8080請求時,nginx響應前端資源,在頁面內,我們點擊按鈕,或者提交表單等操作請求服務器時,nginx檢測到api字樣則進行轉發處理,添加上請求頭刪除api字樣,然後轉發到後臺接口進行處理
附:nginx.conf

方案二
這個方案我沒有使用過,只是理論上可行
具體思路是:
- (前後端都在同一個服務器)添加一個server,監聽一個端口比如8888端口,vue中axios的baseurl請求端口改成8888,然後添加代理,進行轉發到8001端口
以上都爲博主個人理解,如有不對,麻煩指出
