Isiokwu a ga-elekwasị anya na nrụnye bụ isi nke Icinga 1 Ngwaọrụ nlekota site na ọnụọgụ abụọ na CentOS ma ọ bụ RHEL 7, na-eji RepoForge > (nke a na-akpọbu RPMforge) ebe nchekwa maka CentOS 6, yana interface webụ oge ochie nke Apache Webserver nwere yana iji Nagios Plugins nke a ga-etinye na sistemụ gị.

Gụọkwa: Wụnye Nagios Monitoring Tool na RHEL/CentOS

Ihe nrụnye LAMP na RHEL/CentOS 7.0 na-enweghị MySQL na PhpMyAdmin, mana ya na modul PHP ndị a: php-cli

  1. Ịwụnye Basic LAMP na RHEL/CentOS 7.0

Nzọụkwụ 1: Ịwụnye Icinga Monitoring Tool

1. Tupu ịga n'ihu na ntinye Icinga site na ọnụọgụ abụọ tinye RepoForge nchekwa na sistemụ gị site na ịnye iwu na-esonụ, dabere na igwe gị.

# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
# rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm

2. Mgbe RepoForge repositories e kwukwara na gị usoro, malite na Icinga isi echichi na-enweghị web interface ma, site na-agba ọsọ na-esonụ iwu.

# yum install icinga icinga-doc

3. Nzọụkwụ ọzọ bụ ịgbalị ịwụnye Icinga web interface nyere site na ngwugwu icinga-gui. Ọ dị ka ugbu a ngwugwu a nwere ụfọdụ nsogbu na-edozibeghị na CentOS/RHEL 7, ma ọ ga-emepụta ụfọdụ njehie nlele azụmahịa, mana ị nwere ike nweere onwe gị ịnwale ịwụnye ngwugwu ahụ, ma eleghị anya ka edozila nsogbu ahụ.

N'agbanyeghị nke ahụ, ọ bụrụ na ịnweta otu njehie ahụ na igwe gị dị ka foto dị n'okpuru na-egosi gị, jiri usoro a dị ka akọwara ọzọ, ka ị nwee ike ịwụnye Icinga web interface.

# yum install icinga-gui

4. Usoro iji wụnye ngwugwu icinga-gui nke na-enye ntanetị weebụ bụ nke a. Buru ụzọ budata ụdị ngwungwu ọnụọgụ abụọ RepoForge webụsaịtị site na iji iwu wget.

# wget http://pkgs.repoforge.org/icinga/icinga-gui-1.8.4-4.el6.rf.x86_64.rpm

5. Mgbe wget mechara nbudata ngwugwu ahụ, mepụta ndekọ aha ya bụ icinga-gui (ị nwere ike họrọ aha ọzọ ma ọ bụrụ na ịchọrọ), bugharịa icinga-gui RPM ọnụọgụ abụọ na nchekwa ahụ. , tinye nchekwa ma wepụ ọdịnaya RPM site na ịnye usoro iwu na-esote.

# mkdir icinga-gui

6. Ugbu a ị nwere ngwugwu icinga-gui ewepụtara, jiri iwu ls hụ ọdịnaya nchekwa - ọ ga-ebute akwụkwọ ndekọ aha ọhụrụ atọ - etc , usr na var. Malite site n'ịme nbigharị ugboro ugboro nke akwụkwọ ndekọ aha atọ a rụpụtara na nhazi sistemụ faịlụ mgbọrọgwụ gị.

Kwụpụ 2: Gbanwee faịlụ nhazi Icinga Apache yana ikike Sistemụ

7. Dị ka e gosiri na isiokwu a okwu mmeghe, gị usoro kwesịrị ka Apache HTTP nkesa na PHP arụnyere na-enwe ike na-agba ọsọ Icinga Web Interface.

Mgbe ịmechara usoro ndị a dị n'elu, faịlụ nhazi ọhụrụ kwesịrị ịdị ugbu a na Apache conf.d ụzọ akpọrọ icinga.conf. Iji nwee ike ịnweta Icinga site na ebe dịpụrụ adịpụ site na ihe nchọgharị, mepee faịlụ nhazi a ma dochie ọdịnaya ya niile na nhazi ndị a.

# nano /etc/httpd/conf.d/icinga.conf

Gbaa mbọ hụ na ị jiri ihe ndị a dochie ọdịnaya faịlụ niile.
