nginx校验配置文件时报错：nginx: [emerg] “ssl_certificate” directive is not allowed here in /home/hehuang/nginx/nginx/conf/nginx.conf:143

GPT:

你遇到的错误是由于在 stream 模块中使用了 ssl_certificate 指令，而 stream 模块不支持该指令。在 Nginx 中，ssl_certificate 和其他 SSL 相关的配置一般用于 HTTP 模块，而不是 stream 模块。

如果你需要在 stream 模块中启用 SSL，可以使用 ssl 和 ssl_certificate 相关的指令，但它们的配置语法略有不同。可以修改你的 stream 配置，具体方法如下：

stream {
    upstream emqx_cluster {
        server 192.168.0.33:1883 max_fails=2 fail_timeout=30s;
        server 192.168.0.34:1883 max_fails=2 fail_timeout=30s;
    }

    server {
        listen 1883;
        proxy_pass emqx_cluster;
        proxy_buffer_size 4k;
        proxy_connect_timeout 10;
    }

    upstream stream_backend {
        zone tcp_servers 64k;
        hash $remote_addr;
        server 192.168.0.33:1883 max_fails=2 fail_timeout=30s;
        server 192.168.0.34:1883 max_fails=2 fail_timeout=30s;
    }

    server {
        listen 8883 ssl;  # 在 stream 模块中启用 SSL
        proxy_pass stream_backend;
        
        # SSL 配置
        ssl_certificate /home/hehuang/nginx/nginx/certs/emqx.pem;
        ssl_certificate_key /home/hehuang/nginx/nginx/certs/emqx.key;
        ssl_client_certificate /home/hehuang/nginx/nginx/certs/ca.pem;
        ssl_verify_client on;
        ssl_verify_depth 1;
    }

    upstream mqtt_server_manage {
        server 192.168.0.33:18083 max_fails=2 fail_timeout=30s;
        server 192.168.0.34:18083 max_fails=2 fail_timeout=30s;
    }

    server {
        listen 18083;
        proxy_pass mqtt_server_manage;
        proxy_buffer_size 4k;
        proxy_connect_timeout 1;
        #proxy_send_timeout 1;
        #proxy_read_timeout 1;
    }
}

关键修改点：

  1. 在 listen 8883 后面添加了 ssl，启用了 SSL。
  2. 保留了 SSL 证书和相关配置，但放在 server 块中，并且在 stream 中语法正确。

修改后再试试重新加载配置。
