Ansible 从 rpm 包安装 yum repo

Question

我正在尝试使用 Ansible 安装 rpm 包。但是，我无法弄清楚如何正确地做到这一点。我希望有人能帮我解决这个问题。

这是我到目前为止所做的：

1.使用 yum_repository 模块（尝试 1）

    - name: "Setting up percona repository"
      yum_repository:
        name: "Percona"
        description: "Percona yum repository"
        baseurl: "http://www.percona.com/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm"

    - name: "Installing PMM client package"
      yum: pkg={{item}} state=installed
      with_items:
      - pmm-client

结果

    TASK [pmmhosts : Setting up percona repository] **********************************************************************
    changed: [server1]
    changed: [server2]

    TASK [pmmhosts : Installing PMM client package] **********************************************************************
    failed: [server1] (item=[u'pmm-client']) => {"changed": false, "item": ["pmm-client"], "msg": "Failure talking to yum: failure: repodata/repomd.xml from Percona: [Errno 256] No more mirrors to try.
    http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for Percona: Damaged repomd.xml file"}
    failed: [server2] (item=[u'pmm-client']) => {"changed": false, "item": ["pmm-client"], "msg": "Failure talking to yum: failure: repodata/repomd.xml from Percona: [Errno 256] No more mirrors to try.
    http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for Percona: Damaged repomd.xml file"}

2。使用 yum_repository 模块（尝试 2）

    - name: "Setting up percona repository"
      yum_repository:
        name: "Percona"
        description: "Percona yum repository"
        baseurl: "http://www.percona.com/downloads/percona-release/redhat/latest/"

    - name: "Installing PMM client package"
      yum: pkg={{item}} state=installed
      with_items:
      - pmm-client

结果

    TASK [pmmhosts : Setting up percona repository] **********************************************************************
    changed: [server1]
    changed: [server2]

    TASK [pmmhosts : Installing PMM client package] **********************************************************************
    failed: [server1] (item=[u'pmm-client']) => {"changed": false, "item": ["pmm-client"], "msg": "Failure talking to yum: failure: repodata/repomd.xml from Percona: [Errno 256] No more mirrors to try.
    http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for Percona: Damaged repomd.xml file"}
    failed: [server2] (item=[u'pmm-client']) => {"changed": false, "item": ["pmm-client"], "msg": "Failure talking to yum: failure: repodata/repomd.xml from Percona: [Errno 256] No more mirrors to try.
    http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for Percona: Damaged repomd.xml file"}

3。使用 shell 模块（尝试 1）

    - name: "Setting up percona repository"
      shell: "yum install -y http://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm"

    - name: "Installing PMM client package"
      yum: pkg={{item}} state=installed
      with_items:
      - pmm-client

结果 (运行 1)

    TASK [pmmhosts : Setting up percona repository] **********************************************************************
    changed: [server1]
    changed: [server2]
    TASK [pmmhosts : Installing PMM client package] **********************************************************************
    changed: [server1] => (item=[u'pmm-client'])
    changed: [server2] => (item=[u'pmm-client'])

结果 (运行 2)

    TASK [pmmhosts : Setting up percona repository] **********************************************************************
    fatal: [server1]: FAILED! => {"changed": true, "cmd": "yum install -y http://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm", "delta": "0:00:01.363009", "end": "2018-02-28 16:31:23.728102", "msg": "non-zero return code", "rc": 1, "start": "2018-02-28 16:31:22.365093", "stderr": "Error: Nothing to do", "stderr_lines": ["Error: Nothing to do"], "stdout": "Loaded plugins: fastestmirror
    Examining /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: percona-release-0.1-4.noarch
    /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: does not update installed package.", "stdout_lines": ["Loaded plugins: fastestmirror", "Examining /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: percona-release-0.1-4.noarch", "/var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: does not update installed package."]}
    fatal: [server2]: FAILED! => {"changed": true, "cmd": "yum install -y http://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm", "delta": "0:00:01.363009", "end": "2018-02-28 16:31:23.728102", "msg": "non-zero return code", "rc": 1, "start": "2018-02-28 16:31:22.365093", "stderr": "Error: Nothing to do", "stderr_lines": ["Error: Nothing to do"], "stdout": "Loaded plugins: fastestmirror
    Examining /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: percona-release-0.1-4.noarch
    /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: does not update installed package.", "stdout_lines": ["Loaded plugins: fastestmirror", "Examining /var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: percona-release-0.1-4.noarch", "/var/tmp/yum-root-5raeIL/percona-release-0.1-4.noarch.rpm: does not update installed package."]}

结论：

到目前为止，使用 yum_repository 模块，我正在成功安装存储库。但是，我无法从此存储库中获取任何包，因此不再可能执行 "yum install"。另一方面，使用 shell 模块，我能够第一次安装存储库，然后安装包正常运行。但是，由于已安装的存储库出错，我无法再次重现状态。

Answer 1

我会修改你第三次尝试使用 yum 模块来安装 Percona rpm，它会设置存储库并安装所需的 GPG 密钥，它将以幂等方式工作：

- name: "Setting up percona repository"
  yum:
    name: "http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm"
    state: present

- name: Installing PMM client package...
....
