Java 如何與 Ansible 自動運維平台對接？

Java對接ansible自動運維化平台實作檔案擷取分發

此次對接主要為以下兩個功能：

• 文件採集(對文件進行批次操作，包括批量從多台主機中採集共性文件如日誌文件)

• #文件分發(對文件進行批量操作，包括批量從多台主機中分發共通性檔案如日誌檔)

場景說明及ansible yum安裝

因ansible沒有Windows的安裝包，所以為了方便測試，搭建了一套Linux環境進行後續工作。

此次採用yum方式安裝，在採用yum方式安裝Ansible,先安裝EPEL來源。

yum install -y http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

查看EPEL來源中的Ansible版本

yum info ansible

#直接安裝此版本，如果有其他要求，請調整來源，安裝其他ansible版本

#yum install -y ansible

安裝完成之後，查看ansible版本資訊

ansible --version

設定Ansible伺服器清單

清單檔案/etc/ansible/hosts,在此檔案中編寫節點主機的對應IP位址和連接埠

我這裡只是做一個演示，其中IP後面可以添加節點真實的SSH的端口，在定義的內容上面有一個[]列表，裡面的內容為自定義內容，方面為了操作綁定的節點主機，我習慣稱之為分組列表

簡單的認證一下，Ping一下新增的主機

成功安裝ansible ！ ！

Java程式碼實作檔案分發

顧名思義，檔案分發就是把本機的檔案分發到多個主機。

這時候就需要Apache POI(大家可以去導入對應的套件)來建立本機的檔案了(ansible Host設定檔也透過POI建立)

建立主機群組設定檔

註：ansible分為兩種連接方式，這裡採用的是金鑰連接，產生的檔案已拼接金鑰！ ！ ！後續的採集與分發都要用到這個。 （如有不懂的小夥伴，可以去查找ansible的連接方式）

    @Override
    public void ansibleCreateHost(HostInfo hostInfo, String Key) {
        ParamCheckUtils.notNull(hostInfo, "hostInfo");

        List<HostInfo> HostIp = Arrays.asList(hostInfo);
        for (HostInfo data : HostIp) {
            String ansiblePassWd = data.getPasswd();
            String PassWd = hostInfoService.decode(ansiblePassWd);
            data.setPasswd(PassWd);
        }
        try {
            AnsibleCreateFileUtils.passWordConnect(HostIp, ansibleConfigurationItemVo.getHostGroup(),
                ansibleConfigurationItemVo.getDirectory());
        } catch (IOException e) {
            log.error("Failed to create host configuration{}", e);
        }
    }

實現文件分發

主機設定檔已經配置好，接下來就是執行ansible對應的指令，透過Java拼接ansible指令。

同上，呼叫兩個工具類別

@Override
    public void fileCollection(HostInfo hostInfo, String remotePath, String localPath) {
        ansibleCreateHost(hostInfo, null);
        try {
            log.info("remote file path = {}", remotePath);
            log.info("local file path = {}", localPath);

            // 文件采集
            AnsibleExecuteTheOrderUtils.fileCollection(ansibleConfigurationItemVo.getHostGroup(), remotePath,
                localPath , ansibleConfigurationItemVo.getDirectory());
        } catch (Exception e) {
            log.error("主机[{}]文件采集失败,主机ID[{}]:", hostInfo.getHost(), hostInfo.getId(), e);
            throw exceptionBuildService.buildException(OperationExceptionCode.EXECUTE_CMD_ERROR,
                new Object[] {e.getMessage()});

        } finally {
            AnsibleExecuteTheOrderUtils.disconnect();
        }

    }
