华硕ask30bf装win7 (华硕k30bf能装win7吗) 环境


准备工作

配置ansible(deploy 主机执行)

# ssh-keygen# for i in 192.168.3.{21..28}; do ssh-copy-id -i ~/.ssh/id_rsa.pub $i; done

[root@deploy ~]# cat /etc/ansible/hosts [etcd]192.168.3.21192.168.3.22192.168.3.23[k8s-master]192.168.3.24192.168.3.25192.168.3.26[k8s-worker]192.168.3.27192.168.3.28[k8s:children]k8s-masterk8s-worker


优化主机配置

关闭防火墙和selinux

# ansible all -m shell -a "systemctl stop firewalld && systemctl disable firewalld"# ansible all -m shell -a "sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config"

修改limit

关闭交换分区

# swapoff -a# ansible k8s -m shell -a "yes | cp /etc/fstab /etc/fstab_bak"# ansible k8s -m shell -a "cat /etc/fstab_bak | grep -v swap > /etc/fstab"# ansible k8s -m shell -a "echo vm.swappiness = 0 >> /etc/sysctl.d/k8s.conf"# ansible k8s -m shell -a "sysctl -p /etc/sysctl.d/k8s.conf"配置ipvs

配置网桥转发规则

# cat sysctl.sh #!/bin/bashcat > /etc/sysctl.d/k8s.conf << EOFnet.bridge.bridge-nf-call-ip6tables = 1net.bridge.bridge-nf-call-iptables = 1net.ipv4.ip_forward = 1EOFcat <<EOF | tee /etc/modules-load.d/crio.confoverlaybr_netfilterEOFmodprobe overlaymodprobe br_netfiltersysctl --system

# ansible k8s -m script -a "/root/sysctl.sh"配置etcd集群

生成证书(ansible 主机操作)

# curl -o /usr/bin/cfssl https://pkg.cfssl.org/R1.2/cfssl_linux-amd64# curl -o /usr/bin/cfssljson https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64# curl -o /usr/bin/cfssl-certinfo https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64# chmod +x /usr/bin/cfssl*

创建 CA 配置文件

# mkdir p ssl# cd /root/ssl# cat >ca-config.json <<EOF{ "signing": { "default": { "expiry": "876000h" }, "profiles": { "etcd": { "usages": [ "signing", "key encipherment", "server auth", "client auth" ], "expiry": "876000h" } } }}EOF

创建 CA 证书签名请求

# cat >ca-csr.json <<EOF{ "CN": "etcd", "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "ST": "beijing", "L": "beijing", "O": "jdt", "OU": "iot" } ]}EOF

生成 CA 证书和私钥

# cfssl gencert -initca ca-csr.json | cfssljson -bare ca

创建etcd的TLS认证证书

# cat > etcd-csr.json <<EOF{ "CN": "etcd", "hosts": [ "192.168.3.21", "192.168.3.22", "192.168.3.23", "192.168.3.24", "192.168.3.23", "192.168.3.26", "etcd1", "etcd2", "etcd3", "master1", "master2", "master3" ], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "ST": "beijing", "L": "beijing", "O": "jdt", "OU": "iot" } ]EOF

生成 etcd证书和私钥并分发

# cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=etcd etcd-csr.json | cfssljson -bare etcd# ansible etcd -m copy -a "src=/root/ssl/ dest=/export/Data/certs/"

ETCD安装以及配置

创建数据目录

# ansible etcd -m shell -a "mkdir -p /export/Data/etcd_data"

下载etcd并分发

# wget https://github.com/etcd-io/etcd/releases/download/v3.5.1/etcd-v3.5.1-linux-amd64.tar.gz# tar xf etcd-v3.5.1-linux-amd64.tar.gz && cd etcd-v3.5.1-linux-amd64# ansible etcd -m copy -a "src=etcd dest=/usr/bin/"# ansible etcd -m copy -a "src=etcdutl dest=/usr/bin/"# ansible etcd -m copy -a "src=etcdctl dest=/usr/bin/"# ansible etcd -m shell -a "chmod +x /usr/bin/etcd*"

# ansible etcd -m script -a "/root/etcd_config.sh"

启动ETCD

# ansible etcd -m shell -a "systemctl daemon-reload"# ansible etcd -m service -a 'name=etcd state=started'# ansible etcd -m shell -a "systemctl enable etcd"

校验ETCD

修改cri-o 存储路径

# ansible k8s -m shell -a "sed -i -e 's?^graphroot =.*?graphroot = "/export/Data/containers/storage"?g' /etc/containers/storage.conf"

配置cgroup

公有云使用负载均衡代替

高可用LB后续更新,暂用nginx代替

以下操作LB节点执行

[root@lb ~]# yum -y install epel-release.noarch[root@lb ~]# yum -y install nginx nginx-mod-stream

nginx 配置文件中加入以下配置

stream { log_format main '$remote_addr [$time_local]' '$protocol $status $bytes_sent $bytes_received' '$session_time'; server { listen 16443; proxy_pass kubeapi; access_log /var/log/nginx/access.log main; } upstream kubeapi { server 192.168.3.24:6443; server 192.168.3.25:6443; server 192.168.3.26:6443; }}部署k8s

1 、 kubelet日报错 failed to get cgroup stats for "/system.slice/kubelet.service"

解决方案

配置文件中写入 CPUAccounting=true 与 MemoryAccounting=true

[root@master2 ~]# cat /lib/systemd/system/kubelet.service.d/10-kubeadm.conf # Note: This dropin only works with kubeadm and kubelet v1.11+[Service]CPUAccounting=trueMemoryAccounting=trueEnvironment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf"Environment="KUBELET_CONFIG_ARGS=--config=/var/lib/kubelet/config.yaml"# This is a file that "kubeadm init" and "kubeadm join" generates at runtime, populating the KUBELET_KUBEADM_ARGS variable dynamicallyEnvironmentFile=-/var/lib/kubelet/kubeadm-flags.env# This is a file that the user can use for overrides of the kubelet args as a last resort. Preferably, the user should use# the .NodeRegistration.KubeletExtraArgs object in the configuration files instead. KUBELET_EXTRA_ARGS should be sourced from this file.EnvironmentFile=-/etc/sysconfig/kubeletExecStart=ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS

2、kubectl get cs 提示 dial tcp 127.0.0.1:10251: connect: connection refused

[root@deploy ~]# kubectl get csWarning: v1 ComponentStatus is deprecated in v1.19+NAME STATUS MESSAGE ERRORscheduler Unhealthy Get "http://127.0.0.1:10251/healthz": dial tcp 127.0.0.1:10251: connect: connection refused etcd-1 Healthy {"health":"true","reason":""} controller-manager Healthy ok etcd-0 Healthy {"health":"true","reason":""} etcd-2 Healthy {"health":"true","reason":""}
