Question

想在本地设置网站，拥有Ubuntu 18.04（Vargant 2.1，VM 5.2，Ansible） Vagrant文件包含...

Copy

运行vagrant up（provision）并在控制台中收到该错误。

    if ENV.has_key?('verbose')
      ansible.verbose = ENV['verbose']
    end

    ansible.extra_vars = {

end

我应该在vargant文件中写什么来避免这个错误？使用SSH是必要的，没有它可以连接吗？

另一台机器上出现同样的错误（ubuntu 16.04）满堆

TASK [install python2] ********************************************************* fatal: [web3]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Warning: Permanently added '192.168.56.56' (ECDSA) to the list of known hosts.\r\nalex@192.168.56.56: Permission denied (publickey).\r\n", "unreachable": true} to retry, use: --limit @/home/alex/Projects/vm/provision/playbook.retry PLAY RECAP ********************************************************************* web3 : ok=0 changed=0 unreachable=1 failed=0

Answer 1

我在Ansible的Vagrants中做的是：

 "PostgreSQL 8.2.15 (Greenplum Database 4.3.18.0 build 1) on x86_64-unknown-linux-gnu, compiled by GCC gcc (GCC) 4.4.2 compiled on Nov 22 2017 18:54:31"

然后是脚本：

hostsfile.sh：

       required_plugins = %w( vagrant-hostsupdater )
       machine.vm.synced_folder "./", "/vagrant"

       machine.vm.provision "shell", inline: <<-SHELL
        sudo su
        rm -f /etc/localtime && ln -s /usr/share/zoneinfo/UTC /etc/localtime
        echo 'Adding `sudo su` to the `.bashrc` for `vagrant` user...'
        echo 'sudo su' >> /home/vagrant/.bashrc
        echo "Settings the hosts file and Ansible access..."
        bash /vagrant/scripts/hostsfile.sh
        bash /vagrant/scripts/ansible_ssh_key.sh
        echo "Done..."
      SHELL

ansible_ssh_key.sh：

cp /vagrant/files/hostsfile /etc/hosts

文件/ hosts文件

sudo su
USER="ansible"
HOME_DIR="/home/$USER"
useradd -m $USER
usermod -aG sudo $USER
passwd -d $USER
mkdir $HOME_DIR/.ssh
echo 'yourprivkeyhere' >  $HOME_DIR/.ssh/authorized_keys
chown -R $USER:root $HOME_DIR/.ssh
chmod 400  $HOME_DIR/.ssh/authorized_keys
sed -i 's/^#\s*\(%sudo\s*ALL=(ALL)\s*NOPASSWD:\s*ALL\)/\1/' /etc/sudoers

使用此配置，您将能够连接到您的盒子

当然，您应该在127.0.0.1 localhost 172.10.10.11 centos7-1.vagrant.local centos7-1

中添加类似的内容

~/.ssh/config

无法通过Vagrant中的ssh连接到主机（Ansible）
