如何在 apache 中建立 SSH 连接

Question

我正在尝试构建一个网络应用来使用 ansible 管理我的服务器

现在我使用 Centos 7、PHP 7.4、Laravel 8 和 apache 来构建这个应用程序，并且我已经安装了 https://packagist.org/packages/asm/php-ansible composer 包，以便在我的项目中使用 ansible。

这是我的代码：

$ansible = new Asm\Ansible\Ansible(
        '/var/www/xxx/storage/ansible',
        '',
        ''
    );

$ansible->playbook()->play($myplaybookPath)->inventoryFile($myInventoryPath)->execute(function ($type, $buffer) {
        if (Process::ERR === $type) {
            echo 'ERR > '.$buffer ."<br/>";
        } else {
            echo 'OUT > '.$buffer."<br/>";
        }
    });

这是输出：

OUT > PLAY [install nano] ************************************************************
OUT > TASK [Gathering Facts] *********************************************************
OUT > fatal: [xx.xx.14.139]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).", "unreachable": true}
OUT > PLAY RECAP *********************************************************************
OUT > xx.xx.14.139 : ok=0 changed=0 unreachable=1 failed=0 skipped=0 rescued=0 ignored=0
OUT >

库存文件中的用户名和密码是正确的，我测试了很多次，我尝试使用非常简单的密码的新服务器。

我用谷歌搜索了这个错误host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."，我发现它是关于运行 ssh 的用户的授权密钥

我在/var/user/share/httpd/.ssh中为我的apache用户更改了.ssh文件夹的权限和mod

购买此错误仍然存​​在，我不知道如何解决此问题。

感谢帮助

更新

这与我的 Web 服务器配置无关，有关 apache 和 PHP 的一切都可以。

我使用 ansible-playbook 直接从终端运行我的剧本：

ansible-playbook /var/www/xxx/storage/ansible/playbooks/install_nano -i /var/www/xxx/storage/ansible/inventories/testInventory -vvv

我遇到了同样的错误，我猜是关于 InventoryFile 中的 Auth 信息

这是库存文件内容

[linux]

xx.xx.14.139

[linux:vars]

ansible_user=root
ansible_password=testPassword

另外，我尝试了 ansible_ssh_user / password 但它不起作用！

解决办法

我在 ssh 连接中启用了详细模式，我注意到传出的 SSH 请求不支持密码验证。

有 2 个 SSH 配置文件 /etc/ssh/sshd.conf 用于传入请求和 /etc/ssh/ssh.cong 用于传出，因此我从传出的请求配置文件中解决了问题并启用了密码身份验证。

之后，我为我的 apache ssh 文件（如密钥和已知主机文件）设置权限。

之后，我在 laravel 中创建了一个命令，这样我就可以使用 root 用户和 Crond 运行我的 ansible playbook。
