Sådan installeres Oracle Linux Automation Manager (alias "Oracle Ansible Tower")

Hvis du følger de rigtige Oracle-folk, ved du sikkert allerede, at Oracle netop har udgivet Oracle Linux Automation Manager:

Din #Ansible automatiseringsmotor er der muligvis allerede, inkluderet med dit Oracle Linux-abonnement... https://t.co/RPZw37yOvs pic.twitter.com/aQZInFcUsv

— Ludovico Caldara (@ludodba) 6. september 2021

Min forståelse var, at adgang til det krævede ULN-adgang, så der var ingen måde at bare oprette en hurtig VM derhjemme og prøve det... men jeg tog fejl.

Som bekræftet af Ludovico er der offentlig adgang:

Jeg har måske talt for tidligt, det ser ud til, at en offentlig repo også er tilgængelig:https://t.co/XxZhs9oFDi

— Ludovico Caldara (@ludodba) 7. september 2021

Jeg troede, jeg vil holde det simpelt indtil videre, så jeg har lige oprettet en VM med Vagrant og bekræfter, at du kan teste den hjemmefra fra det offentlige lager.

Først skal du tilføje og aktivere det offentlige automationslager til dit system:

Lad os nu oprette administrationsbrugeren og sørge for, at du indstiller det korrekte værtsnavn/IP-adresse for "AWX Instance provision"

Når det er afsluttet, skal vi konfigurere HTTP-serveren.
Da dette kun er en test, kan du bare oprette et ssl-certifikat for at undgå problemer med login på din administrationsgrænseflade (vær venlig ikke at gøre dette på dit produktionssystem :) )

Jeg er sikker på, at du kan ændre webserveren til din yndlingsserver, men indtil videre vil vi konfigurere nginx-serveren, der er standardserveren.
Her har vi lige lavet en sikkerhedskopi af standardkonfigurationen og kopieret standardkonfigurationen fra dokumentationen:

[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.

events {

}

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    # 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 ~]#

Sidste trin, skift blot nogle oplysninger om tårnindstillingsfilen (tilføj blot dit værtsnavn/IP i CLUSTER_HOST_ID) og aktiver/start Oracle Automation Manager Service med 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

Og voilà! du kan nu begynde at administrere dine mulige playbooks direkte fra Oracle Automation Manager Interface






Jeg har virkelig brug for at komme mere ind i Ansible og Automation, så dette kunne være en god måde at begynde at bruge Oracles egen Automation Manager på :)
