二、配置负载均衡集群

负载均衡列表：

test-kube-nginx-lb-01 172.18.1.12
test-kube-nginx-lb-02 172.18.1.10

1. 创建nginx配置

cat >> /etc/nginx.conf << EOF
worker_processes 4;
worker_rlimit_nofile 40000;

events {
    worker_connections 8192;
}

stream {
    upstream rancher_servers_http {
        least_conn;
        server 172.18.1.4:80 max_fails=3 fail_timeout=5s;
        server 172.18.1.5:80 max_fails=3 fail_timeout=5s;
        server 172.18.1.9:80 max_fails=3 fail_timeout=5s;
    }
    server {
        listen     80;
        proxy_pass rancher_servers_http;
    }

    upstream rancher_servers_https {
        least_conn;
        server 172.18.1.4:443 max_fails=3 fail_timeout=5s;
        server 172.18.1.5:443 max_fails=3 fail_timeout=5s;
        server 172.18.1.9:443 max_fails=3 fail_timeout=5s;
    }
    server {
        listen     443;
        proxy_pass rancher_servers_https;
    }
}
EOF

以容器的形式运行nginx服务，而不需要把它安装在宿主机上。将编辑好的NGINX示例配置文件保存到/etc/nginx.conf，并运行以下命令来启动NGINX容器:

docker run -d --restart=unless-stopped   -p 80:80 -p 443:443   -v /etc/nginx.conf:/etc/nginx/nginx.conf   nginx:1.14
