AI摘要

本文详细介绍了Nginx的基础配置，包括反向代理、负载均衡等设置，并展示了在配置过程中遇到的错误。当尝试增加Redis代理配置时，出现报错。解决方法是检查Nginx是否安装了Stream模块，如果没有，则通过yum安装并启用。测试配置正确性的命令为`nginx-t`。

2.报错时nginx配置：

        } 
  }

 server {
        listen       8090;
        server_name  localhost;

        rewrite_log on;
        error_log      /var/log/nginx/error.log notice;
	
	location /download/ {
           root /home/nginx/;
        }

        location /img/ {
           root /home/nginx/;
        }

        location / {
            proxy_pass http://wms;
            proxy_set_header Host $host:$server_port;
        } 
   }

	# nacos-server配置
	server {
		listen 8858;
		server_name nacos.com; #nacos.com 映射配置
		location / {
			proxy_pass http://nacos_server;
			proxy_set_header Host $host;

			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header REMOTE-HOST $remote_addr;
			add_header X-Cache $upstream_cache_status;
			add_header Cache-Control no-cache;
		}
	}

    include /etc/nginx/conf.d/*.conf;

}

3.增加配置报错：

增加配置内容如下：

#redis代理测试
stream {
     upstream redis {
        #redis真实访问地址
        server  192.168.0.2:6701 max_fails=3 fail_timeout=30s;
     }
 
     server {
          #外网监听地址
          listen 6379;
          #代理连接超时时间
          proxy_connect_timeout 5s;
          #代理超时时间
          proxy_timeout 30s;
          #代理名称
          proxy_pass redis;
     }
}

4.增加配置位置如下：

在这里插入图片描述

5.解决办法：

1.nginx -V确保nginx安装了–with -stream如果没有，重新用yum install nginx -y安装
2. 安装 yum -y install epel-release
3. yum -y install nginx-all-modules.noarch
4.vi nginx.conf顶部加一行
load_module /usr/lib64/nginx/modules/ngx_stream_module.so;
