Jika Anda mengikuti orang Oracle yang tepat, Anda mungkin sudah tahu bahwa Oracle baru saja merilis Oracle Linux Automation Manager:
Mesin otomatisasi #Ansible Anda mungkin sudah ada di sana, disertakan dengan langganan Oracle Linux Anda... https://t.co/RPZw37yOvs pic.twitter.com/aQZInFcUsv
— Ludovico Caldara (@ludodba) 6 September 2021
Pemahaman saya adalah bahwa akses ke sana memerlukan akses ULN, jadi tidak ada cara untuk hanya menjalankan VM cepat di rumah dan mencobanya... tapi saya salah.
Seperti yang dikonfirmasi oleh Ludovico, ada akses publik:
Saya mungkin berbicara terlalu dini, sepertinya repo publik juga tersedia:https://t.co/XxZhs9oFDi
— Ludovico Caldara (@ludodba) 7 September 2021
Saya pikir saya akan membuatnya tetap sederhana untuk saat ini, jadi saya baru saja membuat VM dengan Vagrant dan mengonfirmasi bahwa Anda dapat mengujinya dari rumah dari repositori publik tersebut.
Pertama, tambahkan dan aktifkan repositori publik Otomatisasi ke sistem Anda:

Setelah kami memperbarui sistem, kami dapat mencari paket manajer otomatisasi

Instalasi paket otomatisasi cukup sederhana (untuk konfigurasi default/pengujian, tentu saja) dan Anda dapat melihat contoh di bawah yang disalin dari dokumentasi Oracle:

Selanjutnya, kita perlu mengatur konfigurasi menggunakan pengguna AWX.
Sekali lagi, cukup ikuti contoh dokumentasi:
[root@OracleAuto ~]# cat /etc/redis.conf
[...]
unixsocket /var/run/redis/redis.sock
unixsocketperm 775
[root@OracleAuto ~]# /var/lib/ol-automation-manager/ol-automation-manager-DB-init.sh

Sekarang mari buat pengguna manajemen dan pastikan Anda menyetel nama host/alamat IP yang benar untuk "penyediaan Instans AWX"
[awx@OracleAuto ~]$ awx-manage createsuperuser --username admin
Email address: [email protected]
Password:
Password (again):
Superuser created successfully.
[awx@OracleAuto ~]$
[awx@OracleAuto ~]$ awx-manage create_preload_data
Default organization added.
Demo Credential, Inventory, and Job Template added.
(changed: True)
[awx@OracleAuto ~]$ awx-manage provision_instance --hostname=OracleAuto
Successfully registered instance OracleAuto
(changed: True)
[awx@OracleAuto ~]$ awx-manage register_queue --queuename=tower --hostnames=OracleAuto
Creating instance group tower
Added instance OracleAuto to tower
(changed: True)
[awx@OracleAuto ~]$
[awx@OracleAuto ~]$ exit
logout
Setelah itu selesai, kita perlu mengatur server HTTP.
Karena ini hanya sebuah tes, Anda bisa membuat sertifikat ssl untuk menghindari masalah masuk ke antarmuka manajemen Anda (tolong, jangan lakukan ini di sistem produksi Anda :))
[root@OracleAuto ~]# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/tower/tower.key -out /etc/tower/tower.crt
Generating a RSA private key
......+++++
.+++++
writing new private key to '/etc/tower/tower.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:
State or Province Name (full name) []:
Locality Name (eg, city) [Default City]:
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:
Email Address []:
[root@OracleAuto ~]#
Saya yakin Anda dapat mengubah server web ke favorit Anda, tetapi untuk saat ini, kami akan mengatur server nginx yang default.
Di sini, kami baru saja membuat cadangan konfigurasi default dan menyalin konfigurasi default dari dokumentasi:
[root@OracleAuto ~]# mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bk
[root@OracleAuto ~]# nano /etc/nginx/nginx.conf
[root@OracleAuto ~]# cat /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
}
[root@OracleAuto ~]#
Langkah terakhir, cukup ubah beberapa informasi pada file pengaturan menara (cukup tambahkan nama host/IP Anda ke CLUSTER_HOST_ID) dan aktifkan/mulai Layanan Oracle Automation Manager dengan Systemd
[root@OracleAuto ~]# grep -i CLUSTER_HOST_ID /etc/tower/settings.py
CLUSTER_HOST_ID = "OracleAuto"
[root@OracleAuto ~]#
[root@OracleAuto ~]# systemctl enable --now ol-automation-manager.service
Created symlink /etc/systemd/system/multi-user.target.wants/ol-automation-manager.service → /usr/lib/systemd/system/ol-automation-manager.service.
[root@OracleAuto ~]#
Dan voilà! sekarang Anda dapat mulai mengelola playbook yang memungkinkan langsung dari Oracle Automation Manager Interface
Saya benar-benar perlu mempelajari lebih lanjut tentang Ansible dan Automation, jadi ini bisa menjadi cara yang baik untuk mulai menggunakan manajer Automation Oracle :)
