# 修改主节点IP地址
|
||
|
|
|
||
|
|
***本文只在单master节点上测试通过***
|
||
|
|
|
||
|
|
首先修改etcd和api-server的地址
|
||
|
|
|
||
|
|
```bash
|
||
|
|
OLD_IP=""
|
||
|
|
NEW_IP=""
|
||
|
|
sed -e "s/${OLD_IP}/${NEW_IP}/g" -i /etc/kubernetes/manifests/etcd.yaml
|
||
|
|
sed -e "s/${OLD_IP}/${NEW_IP}/g" -i /etc/kubernetes/manifests/kube-apiserver.yaml
|
||
|
|
```
|
||
|
|
|
||
|
|
生成新的conf
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubeadm init phase kubeconfig admin --apiserver-advertise-address ${NEW_IP}
|
||
|
|
```
|
||
|
|
|
||
|
|
生成新的证书
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mv /etc/kubernetes/pki/apiserver.key /etc/kubernetes/pki/apiserver.key.bak
|
||
|
|
mv /etc/kubernetes/pki/apiserver.crt /etc/kubernetes/pki/apiserver.crt.bak
|
||
|
|
kubeadm init phase certs apiserver --apiserver-advertise-address 192.168.0.31
|
||
|
|
```
|
||
|
|
|
||
|
|
重启服务
|
||
|
|
|
||
|
|
***由于docker已被kubernetes抛弃，这里使用的containerd，使用docker的旧版kubernetes要重启docker***
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl restart containerd kubelet
|
||
|
|
```
|
||
|
|
|
||
|
|
更新kubectl的管理conf
|
||
|
|
|
||
|
|
```bash
|
||
|
|
rm -f ~/.kube/config
|
||
|
|
cp /etc/kubernetes/admin.conf ~/.kube/config
|
||
|
|
```
