[root@k8s-node-1 ~]# yum install ipvsadmipset -y
复制

[root@k8s-node-1 ~]# modprobe -- ip_vsmodprobe -- ip_vs_rr modprobe -- ip_vs_wrr modprobe -- ip_vs_sh modprobe --nf_conntrack_ipv4
[root@k8s-node-1 ~]# lsmod |egrep ip_vs
复制

[root@k8s-node-1 ~]# vim /usr/local/kubernetes/conf/env_proxy.sh
添加：
# 创建kube-proxy kubeconfig文件
KUBE_APISERVER="https://192.168.1.3:6443"
 
kubectl config set-cluster kubernetes \
       --certificate-authority=/usr/local/kubernetes/ssl/ca.pem \
       --embed-certs=true  \
       --server=${KUBE_APISERVER} \
       --kubeconfig=/usr/local/kubernetes/conf/kube-proxy.kubeconfig
 
kubectl config set-credentials kube-proxy \
       --client-certificate=/usr/local/kubernetes/ssl/kube-proxy.pem \
       --client-key=/usr/local/kubernetes/ssl/kube-proxy-key.pem \
       --embed-certs=true \
        --kubeconfig=/usr/local/kubernetes/conf/kube-proxy.kubeconfig
 
kubectl config set-context default \
       --cluster=kubernetes \
       --user=kube-proxy \
       --kubeconfig=/usr/local/kubernetes/conf/kube-proxy.kubeconfig
 
kubectl config use-context default \
       --kubeconfig=/usr/local/kubernetes/conf/kube-proxy.kubeconfig
 
 
[root@k8s-node-1 ~]# chmod +x/usr/local/kubernetes/conf/env_proxy.sh
[root@k8s-node-1 ~]# /usr/local/kubernetes/conf/env_proxy.sh
复制

[root@k8s-node-1 ~]# ls /usr/local/kubernetes/conf/kube-proxy.kubeconfig
[root@k8s-node-1 ~]# scp/usr/local/kubernetes/conf/kube-proxy.kubeconfig192.168.1.2:/usr/local/kubernetes/conf/
复制

[root@k8s-node-1 ~]# vim /usr/local/kubernetes/conf/kube-proxy
添加：
KUBE_PROXY_OPTS="--logtostderr=true \
        --v=4 \
       --hostname-override=k8s-node-1 \                          ##修改为本机主机名
        --cluster-cidr=10.244.0.0/16\
--proxy-mode=ipvs\
       --kubeconfig=/usr/local/kubernetes/conf/kube-proxy.kubeconfig"
 
[root@k8s-node-1 ~]# scp /usr/local/kubernetes/conf/kube-proxy 192.168.1.2:/usr/local/kubernetes/conf/
 
3、创建kube-proxysystemd服务
[root@k8s-node-1 ~]# vim/usr/lib/systemd/system/kube-proxy.service
添加：
[Unit]
Description=KubernetesProxy
After=network.target
 
[Service]
EnvironmentFile=-/usr/local/kubernetes/conf/kube-proxy
ExecStart=/usr/local/kubernetes/bin/kube-proxy$KUBE_PROXY_OPTS
Restart=on-failure
 
[Install]
WantedBy=multi-user.target
 
[root@k8s-node-1 ~]# scp/usr/lib/systemd/system/kube-proxy.service 192.168.1.2:/usr/lib/systemd/system/
复制

[root@k8s-node-1 ~]# systemctl enable kube-proxy.service
[root@k8s-node-1 ~]# systemctl start kube-proxy.service
复制

[root@k8s-node-1 ~]# systemctl status kube-proxy.service
复制

[root@k8s-node-1 ~]# ps -elf | grepkube-proxy
复制

[root@k8s-node-1 ~]# netstat -anpt |grep kube-proxy
复制

[root@k8s-node-1 ~]# ipvsadm -Ln
