Bii o ṣe le Fi Apakan ActiveMQ sori CentOS/RHEL 8

ActiveMQ jẹ olokiki, orisun-ṣiṣi, imuse ilana pupọ-pupọ ti middleware-oriented ifiranṣẹ (MOM) pẹlu awọn ẹya iṣowo ti a kọ ni Java, ti a lo lati firanṣẹ awọn ifiranṣẹ laarin awọn ohun elo meji, tabi awọn paati meji ninu ohun elo kan.

O ṣe atilẹyin ọpọlọpọ awọn alabara Awọn Ede-Ede lati Java, C, C ++, C #, Ruby, Perl, Python, PHP, ati awọn ilana gbigbe irin-ajo bi OpenWire, STOMP, MQTT, AMQP, isinmi, ati WebSockets.

Diẹ ninu awọn ọran lilo rẹ pẹlu fifiranṣẹ iṣowo, iṣakojọpọ ati awoṣe fifiranṣẹ async gbogbogbo, ṣiṣan ṣiṣan wẹẹbu ti data, API RESTful si fifiranṣẹ ni lilo HTTP, ati pupọ diẹ sii.

Ninu nkan yii, a yoo ṣalaye fun ọ bi o ṣe le fi ẹya tuntun ti Apache ActiveMQ sori ẹrọ lori CentOS 8 ati pinpin Linux RHEL 8.

Fifi Apache ActiveMQ sori CentOS ati RHEL 8

Lati fi ActiveMQ sori ẹrọ, eto rẹ gbọdọ ti fi Java sori ẹrọ olupin rẹ. Ti Java ko ba fi sii, o le fi sii lori eto rẹ nipa lilo Bawo ni lati Fi Java sori itọsọna CentOS ati itọsọna RHEL 8.

Lọgan ti fi Java sori ẹrọ, o le tẹsiwaju siwaju si aṣẹ wget lati ja package orisun bi o ti han.

# cd /opt
# wget https://www.apache.org/dist/activemq/5.15.10/apache-activemq-5.15.10-bin.tar.gz

Bayi jade faili faili ile-iwe nipa lilo pipaṣẹ cd bi o ti han.

# tar zxvf apache-activemq-5.15.10-bin.tar.gz
# cd apache-activemq-5.15.10

Bayi o yẹ ki o fi package package ActiveMQ rẹ sii ninu itọsọna /opt/apache-activemq-5.15.9 ati pe o le wo awọn akoonu rẹ nipa lilo pipaṣẹ ls.

# ls -l

Lati iṣẹjade ti o wa loke, diẹ ninu awọn ilana itọsọna ti o nilo lati ṣe akiyesi, wọn pẹlu awọn atẹle:

bin - tọju faili alakomeji pẹlu awọn faili miiran ti o jọmọ.

Ṣiṣe ActiveMQ bi Iṣẹ kan Labẹ Systemd

Lati ṣiṣe ActiveMQ bi iṣẹ kan, o nilo lati ṣẹda faili ẹyọ iṣẹ ti ActiveMQ labẹ olumulo ti a pe ni activemq, nitorinaa bẹrẹ nipa ṣiṣẹda olumulo nipa lilo pipaṣẹ useradd bi o ti han.

Idanwo Igbeyewo ActiveMQ

A lo console wẹẹbu ActiveMQ lati ṣakoso ati ṣetọju ActiveMQ nipasẹ ẹrọ lilọ kiri lori ayelujara kan. Lati wọle si i ṣii ẹrọ lilọ kiri lori ayelujara kan ki o tọka si URL atẹle:
