这篇文章主要介绍“Java对接ansible自动运维化平台的方法是什么”，在日常操作中，相信很多人在Java对接ansible自动运维化平台的方法是什么问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”Java对接ansible自动运维化平台的方法是什么”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
Java对接ansible自动运维化平台实现文件采集分发
此次对接主要为以下两个功能：
文件采集(对文件进行批量操作，包括批量从多台主机中采集共性文件如日志文件)
文件分发(对文件进行批量操作，包括批量从多台主机中分发共性文件如日志文件)
场景说明及ansible yum安装
因ansible没有Windows的安装包，所以为了方便测试，搭建了一套Linux环境进行后续工作。
此次采用yum方式安装，在采用yum方式安装Ansible,首先安装EPEL源。
yum install -y http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
查看EPEL源中的Ansible版本
yum info ansible
直接安装此版本，如果有其他要求，请调整源，安装其他ansible版本
yum install -y ansible
安装完成之后，查看ansible版本信息
ansible --version
配置Ansible服务器清单
清单文件/etc/ansible/hosts,在此文件中编写节点主机的对应IP地址和端口
我这里只是做一个演示，其中IP后面可以添加节点真实的SSH的端口，在定义的内容上面有一个[]列表，里面的内容为自定义内容，方面为了操作绑定的节点主机，我习惯称之为分组列表
简单的认证一下，Ping一下添加的主机
成功安装ansible ！！
Java代码实现文件分发
顾名思义，文件分发就是把本机的文件分发到多个主机。
这时候就需要 Apache POI(大家可以去导入对应的包)来创建本机的文件了(ansible Host配置文件也通过POI创建)
POI创建文件工具类
package com.tiduyun.cmp.operation.utils;import com.tiduyun.cmp.common.model.operation.HostInfo;import lombok.extern.slf4j.Slf4j;import org.apache.commons.lang.StringUtils;import org.springframework.stereotype.Component;import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.util.ArrayList;import java.util.List;@Slf4j@Componentpublic class AnsibleCreateFileUtils { private final static String filename = "hosts"; public static String passWordConnect(List<HostInfo> hostInfo, String hostGroup , String directory) throws IOException{ // 创建文件夹对象 创建文件对象 File folder = new File(directory); // 如果文件夹不存在 就创建一个空的文件夹 if (!folder.exists()) { log.info("创建了文件夹{}" , folder); folder.mkdirs(); } File file = new File(directory, filename); // 如果文件不存在 就创建一个空的文件 if (!file.exists()) { try { log.info("创建了文件{}" , file); file.createNewFile(); } catch (IOException e) { log.error("error data{}" , e); } } // 写入数据 // 创建文件字节输出流 FileOutputStream fos = new FileOutputStream(file); try { List<String> list = new ArrayList<>(); for (HostInfo data : hostInfo) { // 开始写 String string = data.getHost() + " ansible_ssh_pass=" + data.getPasswd() + " ansible_ssh_user=" + data.getAccount() + " ansible_ssh_port=" + data.getPort(); list.add(string); } String splicingData = StringUtils.join(list, "\n"); String str = "[" + hostGroup + "]" + "\n" + splicingData; byte[] bytes = str.getBytes(); // 将byte数组中的所有数据全部写入 fos.write(bytes); fos.flush(); log.info("文件内容{}" , str); // 删除文件 // deleteFile(file); // 关闭流 } catch (IOException e) { log.error("error data{}" , e); throw e; }finally { if (fos != null) { fos.close(); } } return directory; } public static void deleteFile(File file) { if (file.exists()) {// 判断路径是否存在 if (file.isFile()) {// boolean isFile():测试此抽象路径名表示的文件是否是一个标准文件。 file.delete(); } else {// 不是文件，对于文件夹的操作 // 保存 路径D:/1/新建文件夹2 下的所有的文件和文件夹到listFiles数组中 File[] listFiles = file.listFiles();// listFiles方法：返回file路径下所有文件和文件夹的绝对路径 for (File file2 : listFiles) { deleteFile(file2); } } file.delete(); } else { log.error("该file路径不存在！！"); } }}创建主机组配置文件
注：ansible分为两种连接方式，这里采用的是密钥连接，生成的文件已拼接密钥！！！后续的采集与分发都要用到这个。（如有不懂的小伙伴，可以去查找一下ansible的连接方式）
@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); } }实现文件分发
主机配置文件已经配置好，接下来就是执行ansible对应的命令，通过Java拼接ansible命令。
执行命令工具类

同上，调用两个工具类
@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(); } }到此，关于“Java对接ansible自动运维化平台的方法是什么”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注编程网网站，小编会继续努力为大家带来更多实用的文章！
