Bagaimanakah Java antara muka dengan platform operasi dan penyelenggaraan automatik Ansible?

Java menyambung kepada platform operasi dan penyelenggaraan automatik yang boleh digunakan untuk merealisasikan pengumpulan dan pengedaran fail

Sambungan ini terutamanya mempunyai dua fungsi berikut:

• Pengumpulan Fail (operasi kelompok pada fail, termasuk pengumpulan kumpulan fail biasa seperti fail log daripada berbilang hos)

• Pengedaran fail (operasi kelompok pada fail, termasuk pengumpulan kumpulan fail daripada berbilang hos) Edarkan fail biasa seperti fail log)

Penerangan senario dan pemasangan ansible yum

Oleh kerana ansible tidak mempunyai pakej pemasangan Windows, persekitaran Linux telah dibina untuk memudahkan ujian.

Kali ini, kaedah yum digunakan untuk memasang Ansible Pertama, pasang sumber EPEL.

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

Lihat sumber EPEL Versi Ansible dalam

yum info ansible

terus pasang versi ini, jika ada keperluan lain, sila laraskan sumber dan pasang versi ansible lain

yum install -y ansible

Selepas pemasangan selesai, semak maklumat versi ansible

ansible --version

Konfigurasikan senarai pelayan Ansible

Fail inventori /etc/ansible/hosts, tulis alamat IP yang sepadan dan port hos nod dalam fail ini

I Saya hanya melakukan demonstrasi di sini Selepas IP, anda boleh menambah port SSH sebenar nod Terdapat senarai [] di atas kandungan yang ditakrifkan saya biasa memanggilnya sebagai senarai kumpulan

Pengesahan mudah dan ping hos yang ditambahkan

Ansible berjaya dipasang! !

Kod Java melaksanakan pengedaran fail

Seperti namanya, pengedaran fail adalah untuk mengedarkan fail setempat kepada berbilang hos.

Pada masa ini, anda memerlukan Apache POI (anda boleh mengimport pakej yang sepadan) untuk mencipta fail setempat (fail konfigurasi Hos yang boleh dibuat juga melalui POI)

Buat fail konfigurasi kumpulan hos

Nota: Ansible dibahagikan kepada dua kaedah sambungan digunakan di sini, dan fail yang dijana mempunyai kunci yang disambungkan! ! ! Ini akan digunakan dalam pengumpulan dan pengedaran seterusnya. (Jika anda tidak faham, anda boleh mencari kaedah sambungan ansible)

    @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(),
