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！
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)
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 ！！
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)

return directory;
}
public static void deleteFile(File file) {

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) {
/*
* 递归作用：由外到内先一层一层删除里面的文件 再从最内层 反过来删除文件夹
* 注意：此时的文件夹在上一步的操作之后，里面的文件内容已全部删除
* 所以每一层的文件夹都是空的 ==》最后就可以直接删除了
*/
deleteFile(file2);
}
}
file.delete();
} else {
log.error("该file路径不存在！！");
}
}
}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);
}
}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。
