简单 apache2 任务上的 ansible-playbook 出错

Question

尝试使用小型编排来处理 ansible，但很快运行就一个简单的 apache 问题提出了问题。在启用 mod_proxy 后重新启动时，失败并显示：

~$ ansible-playbook ansible/playbooks/apache_tomcat_mysql_mongo_stack.yml -u ansible --private-key ~/ansible/ansible.pem

下面是剧本apache_tomcat_mysql_mongo_stack.yml

- hosts: web
  roles:

  sudo: True
  vars:
    document_vhost: False
    proxy_vhost: True

    tomcat_ajp_redirection_port: 8443
    tomcat_ajp_server_fake_name: Server
    tomcat_jvmroute_name: jvmroute1

为了简洁起见，所有相关信息（如 apache 角色和处理程序）都可以在 pastie.org 上找到。我无法真正弄清楚发生了什么，因为它看起来像 ansible 正试图在已经运行ning 之外启动一个不同的 apache 服务。

如何解决此类问题？谢谢

我发现有两件事你可以进一步调查：

msg: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down

这看起来 apache 无法绑定 TCP 端口 80，因为其他东西正在使用它。运行 sudo netstat -ntlp | grep 80 在运行剧本之前，并准确验证哪个进程正在侦听端口 80。确保它是 apache。

AH00015: Unable to open logs

看起来 apache 写入其日志文件的文件系统权限可能是错误的。您还应该验证 /var/log/apache2（或您的发行版的任何路径）的相关目录权限。
