使用 LXC 时，Juju 卡在“待处理”状态

使用 LXC 时，Juju 卡在“待处理”状态

因此我尝试开始使用 Juju，并尝试使用 LXC 在本地执行此操作。

我按照这里的说明进行操作：如何配置 juju 以供本地使用？

不幸的是，这对我来说似乎不起作用。

状态显示如下：

$ juju status
machines:
  0:
    agent-state: running
    dns-name: localhost
    instance-id: local
    instance-state: running
services:
  mysql:
    charm: cs:precise/mysql-1
    relations:
      db:
      - wordpress
    units:
      mysql/0:
        agent-state: pending
        machine: 0
        public-address: null
  wordpress:
    charm: cs:precise/wordpress-0
    exposed: true
    relations:
      db:
      - mysql
    units:
      wordpress/0:
        agent-state: pending
        machine: 0
        open-ports: []
        public-address: null
2012-05-10 14:09:38,155 INFO 'status' command finished successfully

如您所见，代理状态为“待定”，并且没有公共地址可供我访问新创建的站点。我是不是漏掉了什么？

更新：尝试破坏环境并再次执行所有操作（多次）。这是 debug-log 的输出：

答案1

我遇到了同样的错误，在#juju 的好心人的帮助下，我能够确定主机上打开的防火墙阻止了 zookeeper 重新连接主机。

尝试运行：

sudo ufw disable

进而：

sudo juju destroy-environment

然后重新启动。另外，如果这是您第一次在机器上引导环境，请注意初始 charm 下载需要一些时间才能完成，因此在部署单元后请等待 15-20 分钟。

这现在也是一个打开错误，因为 juju 应该自动处理这种情况。

答案2

如果这是您第一次引导本地环境，则需要花费一些时间（取决于下载大约 400MB 的服务器映像数据所需的时间）来构建第一个主映像。在您的“data-dir”路径（在您的 environment.yaml 文件中定义）中，有一个machine-agent.log描述此过程的内容：

2012-05-09 10:04:03,848: juju.agents.machine@INFO: Machine agent started id:0
2012-05-09 10:05:08,175: juju.agents.machine@DEBUG: Units changed old:set([]) new:set(['mysql/0'])
2012-05-09 10:05:08,176: juju.agents.machine@DEBUG: Starting service unit: mysql/0 ...
2012-05-09 10:05:08,222: unit.deploy@DEBUG: Downloading charm cs:precise/mysql-1 to /home/marco/.juju/local/marco-local/charms
2012-05-09 10:05:08,314: unit.deploy@DEBUG: Using <juju.machine.unit.UnitContainerDeployment object at 0x9cccbec> for mysql/0 in /home/marco/.juju/local/marco-local
2012-05-09 10:05:08,375: unit.deploy@DEBUG: Starting service unit mysql/0...
2012-05-09 10:05:08,376: unit.deploy@DEBUG: Creating master container...

稍后您将看到以下内容：

2012-05-09 10:09:40,699: unit.deploy@DEBUG: Created master container marco-local-0-template
2012-05-09 10:09:40,699: unit.deploy@INFO: Creating container mysql-0...
2012-05-09 10:10:31,429: unit.deploy@INFO: Container created for mysql/0
2012-05-09 10:10:31,483: unit.deploy@DEBUG: Charm extracted into container

其中详细说明了几分钟后主容器被创建。

最后，并非每个“本地”引导程序都能正常工作，请尝试运行juju destroy-environment然后重新运行juju bootstrap

答案3

我也遇到了同样的问题。我发现master-customize.logapt-cacher-ng 中的软件包损坏导致 apt-get 失败（我不确定，但我认为这是因为我的笔记本电脑在下载过程中挂起了）。我能够通过访问 来纠正这个问题http://localhost:3142/acng-report.html，检查：

  • 通过文件名和文件目录进行验证（不推荐），
  • 然后通过校验和验证文件内容（慢），同时检测损坏的文件，
  • 然后立即截断损坏的文件。

并单击“开始扫描”和/或“到期”。然后我能够销毁 juju 环境并成功重新部署它。

答案4

除了禁用 ufw，还可以尝试使用以下命令允许 juju（libvirt）网络：

sudo ufw allow from `ip addr show virbr0|tail -n 1 |cut -d' ' -f 6` to any

在我的 Ubuntu 12.04 上有效
