使用PVE快速创建虚拟机集群并搭建docker环境

news 2025/12/29 5:28:59

安装Linux系统

这里以安装龙蜥操作系统AnolisOS8.9为例加以说明。
通过PVE后台上传操作系统ISO镜像。
在这里插入图片描述

然后在PVE上【创建虚拟机】，选定上传的龙蜥操作系统镜像进行系统安装。
注意：在安装过程中，要设定语言、时区、超管用户root的密码、普通用户k8s的账号和密码、内存、磁盘大小等参数。超管用户与普通用户的密码尽量保持一致，来回切换懒得匹配不同的密码。
安装好系统后，如果通过命令sudo su无法提升权限，需要把当前用户加入

# 切换root超管用户
su root# 编辑/etc/sudoers
vi /etc/sudoers# 然后在下面%wheel的下面添加一行，如安装操作系统时创建的普通用户为k8s，则添加%k8s这一行内容
## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL
%k8s    ALL=(ALL)       ALL

保存配置后退出。
为了加快服务器访问速度，还要配置域名解析文件。
编辑Dns解析配置文件，路径在/etc/resolv.conf。

# vi /etc/resolv.conf
search local
nameserver 211.xx.xx.xx     # 域名服务器地址

配置静态IP

编辑网卡配置文件，这里的网卡使用ens18，配置文件在/etc/sysconfig/network-scripts/ifcfg-ens18。注意：不同系统路径可能有差别，根据实际使用的网卡及系统进行配置。

# vi /etc/sysconfig/network-scripts/ifcfg-ens18
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static           # 静态IP方式
IPADDR=172.xx.xx.22        # 具体的IP
NETMASK=255.255.255.0
GATEWAY=172.xx.xx.1        # 网关，不一定为.1
DNS1=211.xx.xx.xx          # DNS地址解析服务器DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=ens18
UUID=xx-xx-xx
DEVICE=ens18
ONBOOT=on                 # 静态网卡跟随系统一起启动

克隆虚拟机

克隆创建好的虚拟机，只需修改hosts和静态IP即可。

修改/etc/hosts中的hostname
修改静态IP
在/etc/sysconfig/network-scripts/ifcfg-ens18

安装基础包

安装wget包

[root@localhost soft]# yum install -y wget

制作快照

对上面创建好的3台虚拟机初始环境创建快照，方便后面回滚使用初始安装的Linux系统重新部署新环境使用。

配置docker环境

更新yum源

更新软件源中的包。

yum update

安装底层工具

yum install -y yum-utils device-mapper-persistent-data lvm2

添加阿里云仓库

# 添加阿里云的docker镜像仓库
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

刷新源信息

yum makecache --timer

下载docker-ce

使用yum -y install docker-ce docker-ce-cli containerd.io命令安装docker相关资源包，更新龙蜥8.9的软件园后，安装的docker版本呢是26.1.3，还是比较新的。

[root@localhost harbor]# yum -y install docker-ce docker-ce-cli containerd.io

验证docker是否安装成功

[root@localhost harbor]# docker -v
Docker version 26.1.3, build b72abbb

展示出具体的docker版本，即说明docker安装成功。
