Kif Jippermettu, Tiskonnettja u Tinstalla Yum Plug-ins

Il-plug-ins YUM huma programmi żgħar li jestendu u jtejbu l-prestazzjoni ġenerali tal-maniġer tal-pakketti. Ftit minnhom huma installati awtomatikament, filwaqt li ħafna mhumiex. Yum dejjem jinnotifikak liema plug-ins, jekk ikun hemm, huma mgħobbija u attivi kull meta tmexxi xi kmand yum.

F'dan l-artikolu qasir, se nispjegaw kif tixgħel jew titfi u tikkonfigura l-plug-ins tal-maniġer tal-pakketti YUM fid-distribuzzjonijiet CentOS/RHEL.

Biex tara l-plug-ins attivi kollha, mexxi kmand yum fuq it-terminal. Mill-output ta 'hawn taħt, tista' tara li l-plug-in l-aktar mgħaġġel tal-mirror huwa mgħobbi.

Jippermettu YUM Plug-ins

Biex tippermetti yum plug-ins, kun żgur li d-direttiva plugins=1 (1 tfisser fuq) teżisti taħt it-taqsima [prinċipali] fil-fajl /etc/yum.conf, kif muri hawn taħt.

# vi /etc/yum.conf

[main]
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1 installonly_limit=5

Dan huwa metodu ġenerali li jippermetti yum plug-ins globalment. Kif se naraw aktar 'il quddiem, tista' tagħmilhom individwalment fil-fajls tal-konfigurazzjoni riċettivi tagħhom.

Jiskonnettja l-Plug-ins tal-YUM

Biex tiddiżattiva l-plug-ins yum, sempliċiment ibdel il-valur ta' hawn fuq għal 0 (jiġifieri off), li tiddiżattiva l-plug-ins kollha globalment.

plugins=0

F'dan l-istadju, huwa utli li wieħed jinnota li:

  • Peress li ftit plug-ins (bħal product-id u subscription-manager) joffru funzjonalitajiet fundamentali yum, mhux irrakkomandat li titfi l-plug-ins kollha speċjalment globalment.
  • It-tieni nett, id-diżattivazzjoni tal-plug-ins globalment hija permessa bħala mod faċli, u dan jimplika li tista' tuża din id-dispożizzjoni meta tinvestiga problema probabbli b'yum.
  • Konfigurazzjonijiet għal diversi plug-ins jinsabu f'/etc/yum/pluginconf.d/.
  • Id-diżattivazzjoni tal-plug-ins globalment f'/etc/yum.conf jegħleb is-settings fil-fajls tal-konfigurazzjoni individwali.
  • U tista' wkoll tiddiżattiva plug-ins yum wieħed jew kollha meta tħaddem yum, kif deskritt aktar 'il quddiem.

Installazzjoni u Konfigurazzjoni ta' Plug-ins Extra YUM

Tista' tara lista tal-plug-ins kollha yum u d-deskrizzjonijiet tagħhom billi tuża dan il-kmand.

Biex tinstalla plug-in, uża l-istess metodu biex tinstalla pakkett. Pereżempju aħna se ninstallaw il-plug-in tal-changelog li jintuża biex juri l-changelogs tal-pakkett qabel/wara l-aġġornament.

# yum install yum-plugin-changelog

Ladarba tkun installat, changelog se jkun attivat awtomatikament, biex tikkonferma tagħti ħarsa lejn il-fajl tal-konfigurazzjoni tiegħu.

# vi /etc/yum/pluginconf.d/changelog.conf

Issa tista' tara l-changelog għal pakkett (httpd f'dan il-każ) bħal dan.

Itfi YUM Plug-ins fil-Linja tal-Kmand

Kif intqal qabel, nistgħu wkoll itfi plug-ins wieħed jew aktar waqt li nħaddmu kmand yum billi nużaw dawn iż-żewġ għażliet importanti.

  • --noplugins – jitfi l-plugins kollha
  • --disableplugin=plugin_name – tiddiżattiva plug-ins wieħed

Tista' tiddiżattiva l-plug-ins kollha bħal f'dan il-kmand yum.

# yum search --noplugins yum-plugin

Il-kmand li jmiss tiddiżattiva l-plug-in, fastestmirror waqt l-installazzjoni tal-pakkett httpd.

# yum install --disableplugin=fastestmirror httpd
