git clone https://github.com/qq676596084/ansible-playbook.git

cd ansible-playbook/Keeplived-Nginx

修改host文件

stream {
    upstream kube-servers {
        hash  consistent;
        server 172.16.100.31:6443 weight=6 max_fails=1 fail_timeout=10s;
        server 172.16.100.32:6443 weight=6 max_fails=1 fail_timeout=10s;
        server 172.16.100.33:6443 weight=6 max_fails=1 fail_timeout=10s;
        server 172.16.100.34:6443 weight=6 max_fails=1 fail_timeout=10s;
        server 172.16.100.35:6443 weight=6 max_fails=1 fail_timeout=10s;
    }

    server {
