Als je de juiste Oracle-mensen volgt, weet je waarschijnlijk al dat Oracle zojuist Oracle Linux Automation Manager heeft uitgebracht:
Uw #Ansible-automatiseringsengine is er misschien al, inbegrepen bij uw Oracle Linux-abonnement... https://t.co/RPZw37yOvs pic.twitter.com/aQZInFcUsv
— Ludovico Caldara (@ludodba) 6 september 2021Ik had begrepen dat toegang ertoe ULN-toegang vereiste, dus er was geen manier om gewoon een snelle VM thuis te draaien en het uit te proberen... maar ik had het mis.
Zoals bevestigd door Ludovico, is er openbare toegang:
Ik heb misschien te vroeg gepraat, het lijkt erop dat er ook een openbare repo beschikbaar is:https://t.co/XxZhs9oFDi
— Ludovico Caldara (@ludodba) 7 september 2021
Ik dacht dat ik het voorlopig simpel zal houden, dus ik heb zojuist een VM gemaakt met Vagrant en bevestig dat je het vanuit huis kunt testen vanuit die openbare repository.
Voeg eerst de openbare repository van Automation toe aan uw systeem en schakel deze in:
[root@OracleAuto ~]# dnf config-manager --add-repo http://yum.oracle.com/repo/OracleLinux/OL8/automation/x86_64

Nadat we het systeem hebben bijgewerkt, kunnen we zoeken naar het automatiseringsbeheerpakket

De installatie van het automatiseringspakket is vrij eenvoudig (uiteraard voor een standaard-/testconfiguratie) en u kunt hieronder een voorbeeld zien dat is gekopieerd uit de Oracle-documentatie:
Oracle Linux Automation Manager installeren

Vervolgens moeten we de configuratie instellen met AWX-gebruiker.
Nogmaals, volg gewoon het documentatievoorbeeld:
[root@OracleAuto ~]# cat /etc/redis.conf
[...]

unixsocketperm 775
[root@OracleAuto ~]# /var/lib/ol-automation-manager/ol-automation-manager-DB-init.sh
* Initializing database in '/var/lib/pgsql/data'

Laten we nu de beheergebruiker maken en ervoor zorgen dat u de juiste hostnaam/IP-adres instelt voor de "AWX-instantievoorziening"
[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
Zodra dat is voltooid, moeten we de HTTP-server instellen.
Aangezien dit slechts een test is, kunt u gewoon een ssl-certificaat maken om problemen met inloggen op uw beheerinterface te voorkomen (doe dit alstublieft niet op uw productiesysteem :))
[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 ~]#
Ik weet zeker dat je de webserver naar je favoriete kunt veranderen, maar voor nu zullen we de nginx-server instellen die de standaardserver is.
Hier hebben we zojuist een back-up gemaakt van de standaardconfiguratie en de standaardconfiguratie gekopieerd uit de documentatie:
[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 ~]#
Laatste stappen, verander gewoon wat informatie over het toreninstellingenbestand (voeg gewoon uw hostnaam/IP toe aan CLUSTER_HOST_ID) en activeer/start de Oracle Automation Manager Service met 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 ~]#
En voila! u kunt nu beginnen met het rechtstreeks beheren van uw ansible-playbooks vanuit de Oracle Automation Manager Interface
Ik moet echt meer in Ansible en automatisering komen, dus dit zou een goede manier kunnen zijn om Oracle's eigen automatiseringsmanager te gaan gebruiken :)
