我有一个 Angular 构建和一个 Laravel 后端,提供在一台服务器上运行的 API。我在 nginx 中配置了它们,前端具有到后端服务器的代理。
后端正在 url 上运行(例如占位符)http://api.example.com前端在 http://example.com 上运行
前端配置:
server {
listen 80;
server_name example.com;
location /api {
proxy_pass http://api.example.com;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}
location / {
root /var/www/angular/em-frontend/dist;
index index.html index.htm;
try_files $uri $uri/ /index.html$is_args$args;
}
}
后端配置:
server {
listen 80;
server_name api.example.com;
root /var/www/angular/em-backend/public;
index index.php index.html index.htm;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ /index.php?$query_string;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
现在,当我从前端执行任何 api 调用时,我会收到来自 nginx 的 502 Bad Gateway 错误。
来自 nginx 错误日志:
2017/12/09 23:30:40 [alert] 5932#5932: 768 worker_connections are not enough
2017/12/09 23:30:40 [error] 5932#5932: *770 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: IP_MASKED, server: example.com, request: "GET /api/endpoint HTTP/1.1", upstream: "http://IP_ADDRESS:80/api/endpoint", host: "example.com", referrer: "http://example.com/dashboard"
知道如何解决这个问题吗?
最佳答案
你必须像这个例子一样在 location block 中使用 proxy-pass:
upstream myproject {
server ip1 ;
server ip2 ;
server ip3 ;
}
location / {
proxy_pass http://myproject;
}
