Centos的vagrant模板的制作

• 账号密码 vagrant:vagrant和root:vagrant
• docker的下载页面 https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/ ,下载的链接 https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm
• Centos的vagrant镜像的下载页面 http://cloud.centos.org/centos/7/vagrant/x86_64/images/ ,下载的链接 http://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vagrant-1805_01.VirtualBox.box
• *Ubuntu的vagrant镜像的下载页面 https://cloud-images.ubuntu.com/
• 用vagrant ssh登录服务器，修改配置文件允许账号远程登录
• 换成阿里的yum源
• 安装docker，并指定加速仓库
• 导出虚拟机前先清空网络配置
• 用vagrant package 导出虚拟机

所以步骤合在一起

# 步骤01 导入vagrant官方的centos7虚拟机模板
vagrant box remove -f CentOS-7-x86_64-Vagrant-1811_02
vagrant box add CentOS-7-x86_64-Vagrant-1811_02 CentOS-7-x86_64-Vagrant-1811_02.VirtualBox.box

# 步骤02 编写Vagrantfile文件
rm -rf CentOS-7-x86_64-Vagrant-1811_02
mkdir -p CentOS-7-x86_64-Vagrant-1811_02
cd CentOS-7-x86_64-Vagrant-1811_02

tee Vagrantfile <<-'EOF'
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.define :centos1811 do |centos1811|
    centos1811.vm.box = "CentOS-7-x86_64-Vagrant-1811_02"
    centos1811.vm.hostname = "centos-1811"
# 官方镜像都不能设置账号密码登录，因为官方原始镜像的/etc/ssh/sshd_config文件配置都是不允许任何账号远程登录的
    centos1811.vm.synced_folder ".", "/vagrant", disabled: true
    centos1811.vm.network :private_network, ip: "192.168.130.11"
    centos1811.vm.provider "virtualbox" do |vb|
      vb.customize [ "modifyvm", :id, "--name", "CentOS-7-x86_64-Vagrant-1811_02", "--memory", "1024", "--cpus", "2" ]
    end
  end
end
EOF

vagrant up

# 步骤03 用vagrant ssh登录服务器，修改配置文件 /etc/ssh/sshd_config 允许账号远程登录
vagrant ssh centos1811
echo "vagrant" | sudo -S sed -ri 's/^#?PubkeyAuthentication\s+.*/PubkeyAuthentication yes/' /etc/ssh/sshd_config ;

echo "vagrant" | sudo -S sed -ri 's/^GSSAPIAuthentication\s+.*/GSSAPIAuthentication no/' /etc/ssh/sshd_config ;
echo "vagrant" | sudo -S systemctl restart sshd

# 步骤04 修改的yum源
echo "vagrant" | sudo -S mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
echo "vagrant" | sudo -S curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
echo "vagrant" | sudo -S echo "export LC_ALL=en_US.UTF-8"  >>  /etc/profile
echo "vagrant" | sudo -S source /etc/profile
echo "vagrant" | sudo -S yum clean all
echo "vagrant" | sudo -S yum makecache
echo "vagrant" | sudo -S yum clean all

# 步骤05 清空网络配置，然后作为模板
# 网上说，要删除 /etc/udev/rules.d/70-persistent-net.rules ，用官方的CentOS-7-x86_64-Vagrant-1811_02.VirtualBox.box创建虚拟机，/etc/udev/rules.d目录下面没有任何文件
# 用官方的CentOS-7-x86_64-Vagrant-1811_02.VirtualBox.box创建虚拟机后，/etc/sysconfig/network-scripts/ifcfg-eth0网卡没有写定什么参数，/etc/sysconfig/network-scripts/ifcfg-eth1网卡配置了IP，应该删掉
echo "vagrant" | sudo -S sed -i '/HWADDR/d' /etc/sysconfig/network-scripts/ifcfg-eth0
echo "vagrant" | sudo -S sed -i '/UUID/d' /etc/sysconfig/network-scripts/ifcfg-eth0
echo "vagrant" | sudo -S rm -rf /etc/sysconfig/network-scripts/ifcfg-eth1
echo "vagrant" | sudo -S shutdown -h now

# 步骤06 在宿主机导出虚拟机
rm -rf centos-1811-vagrant-templates.VirtualBox.box
vagrant package --base=CentOS-7-x86_64-Vagrant-1811_02 --output=centos-1811-vagrant-templates.VirtualBox.box
vagrant box remove -f centos-1811-template
vagrant box remove -f CentOS-7-x86_64-Vagrant-1811_02
vagrant box add centos-1811-template centos-1811-vagrant-templates.VirtualBox.box

# 步骤07 删除virtualbox的centos-1811虚拟机
vagrant destroy -f centos1811
cd ..
rm -rf CentOS-7-x86_64-Vagrant-1811_02

导入vagrant官方的centos7虚拟机模板

vagrant box add centos-7.3 CentOS-7-x86_64-Vagrant-1805_01.VirtualBox.box

编写Vagrant

rm -rf docker-templates
mkdir -p docker-templates
cd docker-templates

# 编写Vagrantfile文件
# =========================================================================================
tee Vagrantfile <<-'EOF'
# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.define :template do |template|
    template.vm.box = "centos-7.3"
    template.vm.hostname = "template"
# 官方镜像都不能设置账号密码登录，因为官方原始镜像的/etc/ssh/sshd_config文件配置都是不允许任何账号远程登录的
    template.vm.synced_folder ".", "/vagrant", disabled: true
    template.vm.network :private_network, ip: "192.168.35.11"
    template.vm.provider "virtualbox" do |vb|
      vb.name = "template"
      vb.memory = "768"
      vb.cpus = "1"
    end
  end
end
EOF
# =========================================================================================

vagrant up

用vagrant ssh登录服务器，修改配置文件允许账号远程登录

# 用vagrant ssh登录服务器，修改配置文件允许账号远程登录，修改/etc/ssh/sshd_config
vagrant ssh template
# 切换到root用户
su root

# PubkeyAuthentication yes    # 打开公钥验证模式
# PasswordAuthentication yes  # 打开密码验证模式
# UseDNS no                   # 修改UseDNS为no，该镜像的UseDNS原来就是no，不用改
# GSSAPIAuthentication no     # 修改GSSAPIAuthentication为no
cat /etc/ssh/sshd_config | grep PubkeyAuthentication
cat /etc/ssh/sshd_config | grep PasswordAuthentication
cat /etc/ssh/sshd_config | grep UseDNS
cat /etc/ssh/sshd_config | grep GSSAPIAuthentication
sed -ri 's/^#?PubkeyAuthentication\s+.*/PubkeyAuthentication yes/' /etc/ssh/sshd_config ;

cat /etc/ssh/sshd_config | grep PubkeyAuthentication
cat /etc/ssh/sshd_config | grep PasswordAuthentication
cat /etc/ssh/sshd_config | grep GSSAPIAuthentication
systemctl restart sshd

修改的yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
echo "export LC_ALL=en_US.UTF-8"  >>  /etc/profile
source /etc/profile
yum clean all
yum makecache
yum clean all

安装docker和docker-compose，并指定加速仓库

yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm  #安装docker

mkdir -p /etc/docker
# https://docker.mirrors.ustc.edu.cn 是中国科学技术大学的docker仓库加速器，好像是实时代理的，但是时好时坏
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://kfp63jaj.mirror.aliyuncs.com"]
}
EOF
systemctl enable docker #设置docker服务开机自启动
sudo systemctl restart docker
curl -L https://mirrors.aliyun.com/docker-toolbox/linux/compose/1.21.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
yum clean all
rm -rf /var/cache/yum

导出虚拟机前先清空网络配置

# 网上说，要删除 /etc/udev/rules.d/70-persistent-net.rules ，用官方的CentOS-7-x86_64-Vagrant-1805_01.VirtualBox.box创建虚拟机，/etc/udev/rules.d目录下面没有任何文件
# 用yum安装了docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm，发现/etc/udev/rules.d目录下面多出了 80-docker.rules 文件
# rm -rf /etc/udev/rules.d/70-persistent-net.rules

# 用官方的CentOS-7-x86_64-Vagrant-1805_01.VirtualBox.box创建虚拟机后，/etc/sysconfig/network-scripts/ifcfg-eth0网卡没有写定什么参数，/etc/sysconfig/network-scripts/ifcfg-eth1网卡配置了IP，应该删掉
sed -i '/HWADDR/d' /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i '/UUID/d' /etc/sysconfig/network-scripts/ifcfg-eth0
rm -rf /etc/sysconfig/network-scripts/ifcfg-eth1
shutdown -h now

在宿主机导出虚拟机

vagrant package --base=template --output=centos7-1805-docker.VirtualBox.box
vagrant box add centos7-1805-docker centos7-1805-docker.VirtualBox.box

Vagrantfile文件

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.define :template do |template|
    template.vm.box = "centos-7.3"
    template.vm.hostname = "template"
    template.vm.synced_folder ".", "/vagrant", disabled: true
    template.vm.network :private_network, ip: "192.168.35.11"
    template.vm.provider "virtualbox" do |v|
      v.customize [ "modifyvm", :id, "--name", "template", "--memory", "1024", "--cpus", "1" ]
