Stream配置[S1]由主节点向节点A同步

在主节点重命名[S1]为[S2]，节点A不能同步重命名，会变成[S1],[S2]共存，这时Stream里的upstream命名就会冲突

另外我这里还有个问题不知道是不是和这个问题有关
主节点第一次向节点A同步[S1]时，节点A也会报[emerg] duplicate upstream "s1_upstream"

通过grep -r "upstream s1_upstream" /etc/nginx/ 也查不到第二个这个upstream

[S1]配置为

map $ssl_preread_server_name $backend_name {
    ~^S1_.*$ s1_upstream;
    default http_backend;
}
upstream s1_upstream {
    server s1-server:55782;
}
upstream http_backend {
    server 127.0.0.1:8443;
}
server {
    listen 443;
    listen [::]:443;
    ssl_preread on;
    proxy_pass $backend_name;
    proxy_protocol on;
    proxy_timeout 20s;
}

找到原因了，但不知道是哪一步操作引起的，nginx.conf变成了下面这样,stream和http的配置都被修改成了include两遍

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /run/nginx.pid;
events {
    worker_connections 1024;
}
http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
        '$status $body_bytes_sent "$http_referer" '
        '"$http_user_agent" "$http_x_forwarded_for"';
    access_log /var/log/nginx/access.log main;
    sendfile on;
    #tcp_nopush     on;
    keepalive_timeout 65;
    #gzip  on;
    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
    include /etc/nginx/sites-enabled/*;
}
stream {
    include /etc/nginx/streams-enabled/*;
    include /etc/nginx/streams-enabled/*;
}
