Juniper NETWORKS Upgrading Control Center kuchokera ku Version 2.34

Mawu Oyamba

Chikalatachi chikukhudzana ndi kukweza kwa Paragon Active Assurance Control Center kuchokera ku mtundu 2.34 kupita ku mtundu wina. Kusinthaku kumaphatikizapo njira zapadera monga kukweza Ubuntu OS kuchokera ku 16.04 kupita ku 18.04. Chikalatachi chili ndi zochitika ziwiri:

• Kusintha kwa Ubuntu 16.04 (ndi Control Center yoyikidwa) ku Ubuntu 18.04.
• Kukhazikitsa kwatsopano kwa Ubuntu 18.04 ndikutsatiridwa ndi kukhazikitsa Control Center ndikusamutsa deta yosunga zobwezeretsera kuchokera pamwambo wakale wa Control Center kupita ku chatsopano.

Kuti muwonjezere zina, chonde onani Zowongolera Zowonjezera.

Chitsanzo A: Kusintha kwa Ubuntu 16.04 ku Ubuntu 18.04

• Yambani ndikuyimitsa ntchito za apache2 ndi maukonde ochita kuyimba:
• Imitsa ntchito zonse za Paragon Active Assurance:
• Tengani zosunga zobwezeretsera za data yazinthu za Paragon Active Assurance.

ZINDIKIRANI: Iyi ndi njira yosunga zobwezeretsera yomwe yalongosoledwa mu Operations Guide, mutu Backing Up Product Data, yongolembedwa mwachidule.

Tsatirani malamulo awa:

ZINDIKIRANI: Lamulo la pg_dump lidzafunsa mawu achinsinsi omwe angapezeke mu /etc/netrounds/netrounds.conf pansi pa "postgres database". Mawu achinsinsi achinsinsi ndi "netrounds".

ZINDIKIRANI: Pakukhazikitsa kwakukulu (> 50 GB), kupanga tarball ya RRD files zitha kutenga nthawi yayitali, ndipo kujambula chithunzithunzi cha voliyumu kungakhale lingaliro labwino. Njira zothetsera izi ndi monga: kugwiritsa ntchito a file dongosolo lomwe limathandizira zithunzithunzi, kapena kutenga chithunzithunzi cha voliyumu yeniyeni ngati seva ikugwira ntchito pamalo enieni.

• Yang'anani kukhulupirika kwa nkhokwe pogwiritsa ntchito script zomwe zaperekedwa netrounds_2.35_validate_db.sh.

CHENJEZO: Ngati script iyi itulutsa machenjezo, musayese njira yosamutsira deta yomwe yafotokozedwa "pansipa" patsamba 5. Lumikizanani ndi chithandizo cha Juniper polemba tikiti pa https://support.juniper.net/support/requesting-support (kupereka zotuluka kuchokera pa script) kuti mavuto ndi nkhokwe athetsedwe musanapitilize kukweza.

• Tengani zosunga zobwezeretsera za kasinthidwe ka Control Center files:

Za exampLe:

• Sinthani Ubuntu kukhala mtundu 18.04. Njira yowonjezera yowonjezera ndi iyi (yosinthidwa kuchokera https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes):
• Kuti muwonjezere pa seva:
• Ikani update-manager-core ngati sichinayikidwe kale.
• Onetsetsani kuti mzere wa Prompt mu /etc/update-manager/release-upgrades wakhazikitsidwa ku 'lts' (kuwonetsetsa kuti OS yakwezedwa mpaka 18.04, mtundu wotsatira wa LTS pambuyo pa 16.04).
• Yambitsani chida chosinthira ndi lamulo la sudo do-release-upgrade.
• Tsatirani malangizo a pa sikirini. Ponena za Paragon Active Assurance ikukhudza, mutha kusunga zosasintha ponseponse. (Zitha kuchitika kuti muyenera kupanga zisankho zosiyanasiyana pazifukwa zosagwirizana ndi Paragon Active Assurance.)
• Ubuntu ikasinthidwa, yambitsaninso dongosolo. Kenako chitani zotsatirazi:
• Sinthani PostgreSQL.
• Sinthani database ya PostgreSQL files kuchokera ku 9.5 kupita ku 10:
• Chotsani mtundu wakale wa PostgreSQL:
• Sinthani phukusi la Paragon Active Assurance.
• Lembani cheke cha tarball yomwe ili ndi mtundu watsopano wa Control Center ndikutsimikizira kuti ndiyofanana ndi cheke ya SHA256 yoperekedwa patsamba lotsitsa:
• Tsegulani tarball ya Control Center:
• Ikani phukusi latsopano la Control Center:
• Chotsani phukusi lachikale:

ZINDIKIRANI: Ndikofunikira kuchotsa mapaketi awa.

• Musanayambe kusamuka kwa database, muyenera kuchita zina zowonjezera. Pitani ku nkhani yoyambira ya Knowledge iyi, yendani pansi mpaka gawo la Zochita ngati kutulutsidwa kwakhazikitsidwa, ndipo chitani masitepe 1 mpaka 4 mwa malangizowo.

ZINDIKIRANI: Osachita sitepe 5 pakadali pano.

• Yendetsani kusamutsa kwa database:

ZINDIKIRANI: Musanasamuke, muyenera kuwonetsetsa kuti cheke chatsatanetsatane chofotokozedwa "pamwambapa" patsamba 2 chimatha popanda cholakwika.

Lamulo la ncc migrate limatenga nthawi yayitali kuti lichite (mphindi zambiri). Iyenera kusindikiza zotsatirazi (zambiri sizinasiyidwe pansipa):

• (Mwasankha) Sinthani phukusi la ConfD ngati mukufuna ConfD:
• Fananizani masinthidwe omwe adasungidwa kale files ndi omwe angoikidwa kumene, ndikuphatikiza pamanja zomwe zili m'magulu awiri a files (ziyenera kukhala m'malo omwewo).
• Yambitsani ntchito za apache2, Kafka, ndi maukonde ochita kuitana:
• Yambitsani ntchito za Paragon Active Assurance:
• Kuti mutsegule kasinthidwe katsopano, muyeneranso kuthamanga:
• Ikani nkhokwe zatsopano za Test Agent:
• Popeza kuthandizira kwa Test Agent Lite kudatsitsidwa mu mtundu 2.35, muyenera kuchotsa mapaketi akale a Test Agent Lite ngati mwawayika:

ZINDIKIRANI: Mukakweza mpaka 3.x kenako, muyenera kuyamba ndikuyendetsa lamulo ili: sudo apt-mark osagwira python-django python-django-wamba.

Chitsanzo B: Kuyika Kwatsopano kwa Ubuntu 18.04

• Pa Ubuntu 16.04 chitsanzo, tengani zosunga zobwezeretsera za Paragon Active Assurance data.

ZINDIKIRANI: Iyi ndi njira yosunga zobwezeretsera yomwe yalongosoledwa mu Operations Guide, mutu wakuti “Backing Up Product Data”, yongonenedwa mwachidule.

Tsatirani malamulo awa:

ZINDIKIRANI: Lamulo la pg_dump lidzafunsa mawu achinsinsi omwe angapezeke mu /etc/netrounds/netrounds.conf pansi pa "postgres database". Mawu achinsinsi achinsinsi ndi "netrounds".

ZINDIKIRANI: Pakukhazikitsa kwakukulu (> 50 GB), kupanga tarball ya RRD files zitha kutenga nthawi yayitali, ndipo kujambula chithunzithunzi cha voliyumu kungakhale lingaliro labwino. Njira zothetsera izi ndi monga: kugwiritsa ntchito a file dongosolo lomwe limathandizira zithunzithunzi, kapena kutenga chithunzithunzi cha voliyumu yeniyeni ngati seva ikugwira ntchito pamalo enieni.

• Pa Ubuntu 16.04 chitsanzo, tengani zosunga zobwezeretsera za kasinthidwe ka Control Center files:

• /etc/netrounds/probe-connect.conf
• /etc/openvpn/netrounds.conf

Za exampLe:

• Pa chitsanzo cha Ubuntu 16.04, sungani chilolezo file.
• Chitsanzo chatsopanocho chiyenera kukwaniritsa zofunikira za hardware zofanana ndi zakale.
• Pachitsanzo chatsopano, ikani Ubuntu 18.04. Timalimbikitsa phunziro ili:
• https://ubuntu.com/tutorials/install-ubuntu-server

Ponena za Paragon Active Assurance ikukhudza, mutha kusunga zosasintha ponseponse. (Zitha kuchitika kuti muyenera kupanga zisankho zosiyanasiyana pazifukwa zosagwirizana ndi Paragon Active Assurance.)

• Ubuntu 18.04 ikakhazikitsidwa, yambitsaninso dongosolo.
• Magawo otsatirawa a disk akulimbikitsidwa, makamaka pazosunga zosunga zobwezeretsera (koma zili ndi inu ngati wogwiritsa kusankha):
• Kugawa kovomerezeka pakukhazikitsa labu:
• /: disk yonse, ext4.
• Magawo omwe akulimbikitsidwa kuti akhazikitse:
• /: 10% ya disk space, ext4.
• / var: 10% ya disk space, ext4.
