Uziphindaphinda njani ii-database kwi-MariaDB?
Ukuphendula i-database kwi-MariaDB yinto ebalulekileyo yokuqinisekisa ukufumaneka kunye nokhuseleko lwedatha yakho. Ukuphindaphinda kukuvumela ukuba ube neekopi ezichanekileyo zedatha yakho kwiindawo ezahlukeneyo, okubalulekileyo kwimeko yokulahleka kwedatha okanye ukusilela kwenkqubo. Kweli nqaku, siya kukuchazela inyathelo ngenyathelo uphinda-phinda njani oovimba beenkcukacha kwi-MariaDB ukuze ugcine idatha yakho ikhuselekile kwaye ifikeleleke ngamaxesha onke.

Inyathelo ngenyathelo ➡️ Uphinda-phinda njani oovimba beenkcukacha kwi-MariaDB?

• Faka kwaye uqwalasele iMariaDB kwiiseva: Into yokuqala ekufuneka uyenzile kukufaka i-MariaDB kwiseva ephambili kunye neseva ye-replica. Qinisekisa ukuba zombini ufakelo lukwinguqulelo enye ukunqanda imiba yokuhambelana.
• Qwalasela umncedisi oyintloko: Fikelela kwiseva ephambili kwaye uvule ifayile yoqwalaselo kaMariaDB. Fumana icandelo lophindaphindo loqwalaselo kwaye wenze ukuloga kokubini. Eli nyathelo liyimfuneko ukuze umncedisi akwazi ukuthumela idatha kwiiseva eziphindaphindayo.
• Yenza umsebenzisi ophindaphindayo: Kumncedisi wokuqala, yenza umsebenzisi othile wokuphindaphinda. Lo msebenzisi kufuneka abe neemvume zophindaphindo kunye nofikelelo olusuka kwidilesi ye IP yomncedisi wophindaphindo.
• Yenza i-database yokulahla: Ngaphambi kokuqala ukuphindaphinda, kuyacetyiswa ukuba wenze i-database yokulahla ukuqinisekisa ukuba iiseva zokuphindaphinda ziqala ngolwazi olufanayo nomncedisi oyintloko.
• Qwalasela iseva yesipili: Fikelela kwi-replica server kwaye uvule ifayile yoqwalaselo ye-MariaDB. Ixelela umncedisi ukuba iza kusebenza njengekhoboka kwaye iseke useto lomdibaniso kunye nomncedisi omkhulu.
• Qala inkqubo yophindaphindo: Nje ukuba yonke into iqwalaselwe, qalisa kwakhona zombini iiseva zeMariaDB. Emva koko, iqala inkqubo yophindaphindo kwi-replica server. Ukususela kulo mzuzu ukuya phambili, umncedisi uya kufumana kwaye asebenzise idatha ethunyelwe kumncedisi oyintloko.

Q&A

Imibuzo Ebuzwa Rhoqo malunga nokuReplication Database kwi-MariaDB

Yintoni ukuphindaphindwa kwedatha kwi-MariaDB?

1. Ukuphindaphindwa kwedatha kwi-MariaDB yinkqubo yokukopisha kunye nokugcina idatha ehlaziyiweyo kwisiseko sedatha kwiseva enye ukuya kwenye.

Ziziphi izibonelelo zokuphindaphinda i-database kwi-MariaDB?

1. Ukuphucula ukusebenza kwedatha kunye nokufumaneka.
2. Inika ukhuseleko lokungafuneki kunye nokungaphumeleli.
3. Iququzelela ubungakanani bedatha.

Zeziphi iimfuno zokuphinda-phinda oovimba beenkcukacha kwi-MariaDB?

1. Yiba nobuncinci iiseva ezimbini ezine-MariaDB ezifakiwe.
2. Ukufikelela kwinethiwekhi phakathi kweeseva ukunxibelelana.

Ngawaphi amanyathelo okuqwalasela ukuphindaphindwa kwedatha kwi-MariaDB?

1. Lungisa ubumbeko lomncedisi omkhulu.
2. Yenza umsebenzisi ngeemvume zophindaphindo kwi-master server.
3. Thatha i-backup ye-database kwaye uyibuyisele kumncedisi wekhoboka.
4. Qwalasela umncedisi wekhoboka ukuze adibanise nomncedisi oyintloko.

Ukubekwa esweni njani ukuphindaphindwa kwedatha kwi-MariaDB?

1. Sebenzisa inkcazo ye-SHOW SLAVE STATUS ukufumana ulwazi malunga nobume bokuphindaphinda kumncedisi wekhoboka.

Zeziphi iingxaki ezinokubakho xa uphinda-phinda ugcino lweenkcukacha kwi-MariaDB?

1. Ukusilela kuqhagamshelwano lwenethiwekhi phakathi kweeseva.
2. Iingxabano eziphindaphindayo ezinokubangela ukungangqinelani kwedatha.

Uzisombulula njani iingxaki zokuphindaphinda kwedatha kwi-MariaDB?

1. Hlaziya iilog zokuphindaphinda ukuchonga iimpazamo ezinokubakho.
2. Qinisekisa ubumbeko lwenethiwekhi phakathi kweeseva.

Uthini umahluko phakathi kwe-synchronous kunye ne-asynchronous replication kwi-MariaDB?

1. Ukuphindaphinda kwe-synchronous kuqinisekisa ukuba idatha ibhaliwe kumncedisi wekhoboka ngaphambi kokuba wenze umsebenzi kwi-master server, eqinisekisa ukuhambelana kwedatha kodwa inokuchaphazela ukusebenza.
2. Ukuphindaphindwa kwe-Asynchronous kuvumela imisebenzi ukuba igqibezele kwi-master server ngaphambi kokuba iphindwe kumncedisi wekhoboka, onokuba nokulibaziseka okuncinci ekuhlaziyeni idatha kodwa igcine ukusebenza okungcono.

Ngaba kunokwenzeka ukuphindaphinda i-database esuka ku-MariaDB ukuya kwenye i-database evela kumnikezeli owahlukileyo?

1. Ewe, inokwenzeka kodwa iyantlukwano kwi-syntax kunye nokuziphatha phakathi kwabanikezeli bedatabase kufuneka kuthathelwe ingqalelo.

Sesiphi esona senzo silungileyo sokugcina ingqibelelo yogcino-lwazi oluphindiweyo kwi-MariaDB?

1. Yenza iimvavanyo zokuphindaphinda rhoqo ukuqinisekisa ukuhambelana kwedatha.
2. Ukuphumeza imigaqo-nkqubo yokugcina kunye nokubuyisela kwimeko yokusilela.
