rm -r /etc/nginx/*

最简反向代理配置

events {

}

http {
    server {
        listen 80;
        location / {
            proxy_pass https://www.baidu.com;
        }
    }
}

最简负载均衡

events {

}

http {
    upstream cluster {
        server ubuntu101:8080 weight=1;
        server ubuntu102:8080 weight=1;
        server ubuntu103:8080 weight=1;
    }
    location / {
        proxy_pass http://cluster;
    }
}
