OCP 4.3集群安装

744

一、简介

Openshift从4.0时代从OKD(Openshift Kubernetes Distribution)更名为OCP（openshift container platform)

二、安装操作

1、安装架构

图片[1]-OCP 4.3集群安装-不念博客
安装架构
VM Name硬件配置OSIP地址服务
ocp43-tools4C8G100G系统盘CentOS 7.7192.168.1.80PXE、DHCP 、DNS、Web Server、TFTP、NFSv4、Load Balance
ocp43-bootstrap4C8G100G系统盘暂不安装OS
后续会使用辅助节点上的PXE安装上Readhat CoreOS		192.168.1.55临时K8S集群，用来安装OCP、安装完后可以弃用
ocp43-master18C16G100G系统盘暂不安装OS
后续会使用PXE安装上Readhat CoreOS		192.168.1.81OCP集群Master节点
ocp43-worker18C16G100G系统盘暂不安装OS
后续会使用PXE安装上Readhat CoreOS		192.168.1.91OCP集群Worker节点

2、需预先提供的事项

2.1、在ESXI中创建以上配置的虚拟机

  • 可使用govc命令快速创建
  • ocp43-bootstrap、ocp43-master1、ocp43-worker1虚拟机创建后先关机
  • ocp43-bootstrap、ocp43-master1、ocp43-worker1虚拟机的网卡Mac地址，获取方式可使用govc命令：
govc device.info -vm ocp4-worker1 |grep "MAC Address:"
govc device.info -vm ocp4-worker1 |grep "MAC Address:"
govc device.info -vm ocp4-worker1 |grep "MAC Address:"

2.2、辅助节点安装PXE/DHCP/DNS/LB

可使用红帽大神开源的Ansible部署脚本，github地址：https://github.com/RedHatOfficial/ocp4-helpernode

2.3、拉取镜像的pull secret

echo | openssl s_client -connect api-int.ocp43.curiouser.com:6443 | openssl x509 -noout -text
echo | openssl s_client -connect api-int.ocp43.curiouser.com:6443 | openssl x509 -noout -text
echo | openssl s_client -connect api-int.ocp43.curiouser.com:6443 | openssl x509 -noout -text

3、辅助节点准备

3.1、基础环境准备

  • 开启SELinux
  • 固定IP地址
  • 生成SSH密钥
  • 设置代理
  • 设置主机名
  • 开启ssh-agent
  • 安装ansible、git等基础软件
sed -i 's/SELINUX=disabled/SELINUX=enforcing/g' /etc/selinux/config
echo 'export HTTP_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export HTTPS_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export NO_PROXY="mirrors.ustc.edu.cn,api.ocp43.curiouser.com"' >> ~/.zshrc
source ~/.zshrc
hostnamectl set-hostname --static tools.ocp43.curiouser.com
echo "PREFIX=24\nIPADDR=192.168.1.80\nGATEWAY=192.168.1.1" >> /etc/sysconfig/network-scripts/ifcfg-ens32
sed -i 's/dhcp/static/g' /etc/sysconfig/network-scripts/ifcfg-ens32
yum -y install ansible git
ssh-keygen -t rsa -b 4096 -N "" -f ~/.ssh/id_rsa
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
sed -i 's/SELINUX=disabled/SELINUX=enforcing/g' /etc/selinux/config

echo 'export HTTP_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export HTTPS_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export NO_PROXY="mirrors.ustc.edu.cn,api.ocp43.curiouser.com"' >> ~/.zshrc
source ~/.zshrc

hostnamectl set-hostname --static tools.ocp43.curiouser.com

echo "PREFIX=24\nIPADDR=192.168.1.80\nGATEWAY=192.168.1.1" >> /etc/sysconfig/network-scripts/ifcfg-ens32
sed -i 's/dhcp/static/g' /etc/sysconfig/network-scripts/ifcfg-ens32

yum -y install ansible git

ssh-keygen -t rsa -b 4096 -N "" -f ~/.ssh/id_rsa
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
sed -i 's/SELINUX=disabled/SELINUX=enforcing/g' /etc/selinux/config

echo 'export HTTP_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export HTTPS_PROXY="http://192.168.1.7:8001"' >> ~/.zshrc
echo 'export NO_PROXY="mirrors.ustc.edu.cn,api.ocp43.curiouser.com"' >> ~/.zshrc
source ~/.zshrc

hostnamectl set-hostname --static tools.ocp43.curiouser.com

echo "PREFIX=24\nIPADDR=192.168.1.80\nGATEWAY=192.168.1.1" >> /etc/sysconfig/network-scripts/ifcfg-ens32
sed -i 's/dhcp/static/g' /etc/sysconfig/network-scripts/ifcfg-ens32

yum -y install ansible git

ssh-keygen -t rsa -b 4096 -N "" -f ~/.ssh/id_rsa
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa

由于主机名修改需要重启才能生效，所以该节点需要重启（虽然也可以不重启修改主机名、但是修改的地方较多、以防万一留下隐患、保险起见重启吧）

3.2、下载Ansible脚本

git clone https://github.com/RedHatOfficial/ocp4-helpernode
git clone https://github.com/RedHatOfficial/ocp4-helpernode
git clone https://github.com/RedHatOfficial/ocp4-helpernode

3.3、创建配置文件

3.4、预下载安装OCP/RedHat CoreOS的二进制文件

辅助节点上的PXE服务需要给集群其他节点提供安装OCP和基础OS的二进制文件。在Ansilbe脚本执行时会去联网下载、我们可以收到先下载下来放到指定的文件夹下，加速Ansible执行速度。这些文件的下载地址可以在Ansible脚本文件中查看。

手动下载完后、需要将它们重名并放到指定路径下

cp openshift-client-linux-4.3.8.tar.gz /usr/local/src/openshift-client-linux.tar.gz
cp openshift-install-linux-4.3.8.tar.gz /usr/local/src/openshift-install-linux.tar.gz
mkdir -p /var/www/html/install/ /var/lib/tftpboot/rhcos/ /var/lib/tftpboot/rhcos/

cp rhcos-4.3.8-x86_64-installer-kernel /var/lib/tftpboot/rhcos/kernel
# 因为后续会使用到openshift安装工具openshift-instsall，所以在辅助节点也解压一份命令到可执行路径下
tar -zxvf ~/openshift-install-linux-4.3.8.tar.gz -C /usr/local/bin/
rm -rf /usr/local/bin/README.md

tar -zxvf ~/openshift-install-linux-4.3.8.tar.gz -C /usr/local/bin/
rm -rf /usr/local/bin/README.md

3.5、执行Ansible脚本

cd ~/ocp4-helpernode
ansible-playbook -e @vars.yaml tasks/main.yml
cd ~/ocp4-helpernode
ansible-playbook -e @vars.yaml tasks/main.yml
cd ~/ocp4-helpernode
ansible-playbook -e @vars.yaml tasks/main.yml

3.6、检查辅助节点上安装的服务状况

/usr/local/bin/helpernodecheck
        {dns-masters|dns-workers|dns-etcd|dns-other|install-info|haproxy|services|nfs-info}
/usr/local/bin/helpernodecheck
        {dns-masters|dns-workers|dns-etcd|dns-other|install-info|haproxy|services|nfs-info}
/usr/local/bin/helpernodecheck
        {dns-masters|dns-workers|dns-etcd|dns-other|install-info|haproxy|services|nfs-info}

4、创建安装OCP配置文件

4.1、创建配置文件的定义信息文件

mkdir ~/ocp43
bash -c 'cat > ~/ocp43/install-config.yaml << EOF
apiVersion: v1
# 要与～/ocp4-helpernode/vars.yaml的dns.domain保持一致
baseDomain: curiouser.com
compute:

  replicas: 1

  name: ocp43
networking:
  clusterNetwork:
  - cidr: 10.128.0.0/14
    hostPrefix: 23
  networkType: OpenShiftSDN
  serviceNetwork:
  - 172.30.0.0/16
platform:
  none: {}
fips: false
pullSecret: '2.3章节在红帽官网生成的pull secret'
sshKey: 'ssh密钥的公钥'
EOF'
mkdir ~/ocp43
bash -c 'cat > ~/ocp43/install-config.yaml << EOF
apiVersion: v1

    hostPrefix: 23

  serviceNetwork:
  - 172.30.0.0/16
platform:
  none: {}
fips: false

sshKey: 'ssh密钥的公钥'
EOF'
mkdir ~/ocp43
bash -c 'cat > ~/ocp43/install-config.yaml << EOF
apiVersion: v1
# 要与～/ocp4-helpernode/vars.yaml的dns.domain保持一致
baseDomain: curiouser.com
compute:

platform:
  none: {}
fips: false
pullSecret: '2.3章节在红帽官网生成的pull secret'
sshKey: 'ssh密钥的公钥'
EOF'

4.2、使用openshift-install工具命令生成配置文件

./openshift-install create manifests --dir=ocp43
./openshift-install create manifests --dir=ocp43
./openshift-install create manifests --dir=ocp43

4.3、使用openshift-install工具命令生成PXE安装CoreOS的ignition文件

./openshift-install create ignition-configs --dir=ocp43
# 上述命令会在～/ocp43路径下生成以下文件
auth
bootstrap.ign
master.ign
metadata.json
worker.ign
./openshift-install create ignition-configs --dir=ocp43

# 上述命令会在～/ocp43路径下生成以下文件
auth
bootstrap.ign
master.ign
metadata.json
worker.ign
./openshift-install create ignition-configs --dir=ocp43

# 上述命令会在～/ocp43路径下生成以下文件
auth
bootstrap.ign
master.ign
metadata.json
worker.ign

将ign文件拷贝到/var/www/html/ignition目录下，并修改权限

cd ocp43
cp bootstrap.ign master.ign worker.ign /var/www/html/ignition
chmod 775 /var/www/html/ignition/*
cd ..
cd ocp43
cp bootstrap.ign master.ign worker.ign /var/www/html/ignition
chmod 775 /var/www/html/ignition/*
cd ..
cd ocp43
cp bootstrap.ign master.ign worker.ign /var/www/html/ignition
chmod 775 /var/www/html/ignition/*
cd ..

5、将集群节点虚拟机开机

要是辅助节点上所有的服务准备就绪了、此时将ocp43-bootstrap、ocp43-master1、ocp43-worker1节点虚拟机开机。它们就会发现局域网内辅助节点上的DHCP、TFTP、PXE服务，自动从网卡启动，然后在PXE服务的引导下拉取OS镜像文件安装操作系统。

6、执行等待安装完成命令

openshift-install --dir=ocp43 wait-for bootstrap-complete --log-level=info
openshift-install --dir=ocp43 wait-for bootstrap-complete --log-level=info
openshift-install --dir=ocp43 wait-for bootstrap-complete --log-level=info

7、注意事项！等待、等待、等待

  • 在安装过程中，由于Bootstrap、Master、Worker节点默认时区是UTC时区，而pull secret的有效期是一天，申请完后立即安装的话。安装过程中安装组件式时报证书无效，需要等到8小时，让系统时间等到pull secret有效期。
  • 可通过 echo | openssl s_client -connect api-int.ocp43.curiouser.com:6443 | openssl x509 -noout -text 查看pull secret相关证书的有效期
  • 疑问待后续解决的：集群节点为什么会出现时区设置不一致的？为什么手动设置时区后，系统层面生效但POD没有及时生效？是不是需要改动tool节点上某个服务的配置？

8、验证

tar -zxvf ~/openshift-client-linux-4.3.8.tar.gz -C /usr/local/bin/
export KUBECONFIG=~/ocp43/auth/kubeconfig
oc get node
