Nginx 反向代理从客户端向定义的端口发送和接收请求,这通常是一个响应请求的过程,问题是如果其中一个请求的进程崩溃,整个并行线程也会崩溃,我知道应该避免这种情况,并且通过使用服务它可以在崩溃后运行,但 nginx 可以利用多个独立的并行进程吗?它还有一个丢失静态的缺点,但对我来说这并不重要。

我最终使用了 HAProxy,它是一个负载均衡器,可以完成以下工作:
global
log /dev/log local0
log /dev/log local1 notice
chroot /var/lib/haproxy
stats socket /run/haproxy/admin.sock mode 660 level admin
stats timeout 30s
user haproxy
group haproxy
daemon
