- Ukugcina isizindalwazi sakho sivikelekile kudinga ukuphathwa okusebenzayo komsebenzisi.
- Ukusebenzisa umgomo welungelo elincane kubalulekile ekunikezeni izimvume ezifanele.
- Ukuhlola okuvamile kusiza ukuthola umsebenzi osolisayo futhi kuthuthukise ukusebenza.
- Ukubhalwa kwezinqubomgomo nezinqubo kuqinisekisa ukuphathwa komsebenzisi okungaguquki nokunesibopho.
Ukuphathwa komsebenzisi ku-MySQL
Ukuphathwa komsebenzisi ku-MySQL kuyisici esiyisisekelo sokugcina isizindalwazi esiphephile nesihlelekile. Njengomphathi wesizindalwazi , kungumthwalo wakho wemfanelo ukudala ama-akhawunti omsebenzisi, ukunikeza izimvume ezifanele, nokuqapha umsebenzi womsebenzisi. Ukwenza kanjalo ngendlela efanele akugcini nje ngokuvikela idatha yakho kodwa futhi kuthuthukisa ukusebenza kahle.
- Landela isimiso sokungabi namalungelo amancane
- Sebenzisa amagama ayimfihlo aqinile futhi uwashintshe njalo
- Hlola umsebenzi womsebenzisi
- Hoxisa izimvume ezingadingekile
- Bhala izinqubomgomo nezinqubo zakho
Ucabanga ngalezi zimiso, hlola lezi zigaba ezilandelayo ukuze uthole isiqondiso sesinyathelo ngesinyathelo sendlela yokusebenzisa le mikhuba emihle kakhulu kusizindalwazi sakho se-MySQL . Ekugcineni, uzoba namakhono owadingayo ukuphatha abasebenzisi njengochwepheshe.
Ukudala ama-Akhawunti Womsebenzisi
Isinyathelo sokuqala sokuphatha abasebenzisi ku-MySQL ukwenza ama-akhawunti omuntu ngamunye noma uhlelo lokusebenza oludinga ukufinyelela kusizindalwazi. Nansi indlela yokwenza:
- Ngena ngemvume ku-MySQL njengomsebenzisi wempande:
mysql -u impande -p
- Dala umsebenzisi omusha ngomyalo othi CREATE USER:
DALA UMSEBENZISI 'Igama lomsebenzisi'@'localhost' KHONJWA 'Ngephasiwedi';
Esikhundleni
'nombre_usuario'negama olifunayo futhi'contraseña'ngephasiwedi evikelekile. - Nikeza izimvume kumsebenzisi omusha ngomyalo we-GRANT:
NIKEZA UKUKHETHA, FAKA, BUYEKEZA Egameni_lesizindalwazi.* KU 'Igama_lomsebenzisi'@'localhost';
Lokhu kunikeza izimvume ze-SELECT, INSERT, kanye ne-UPDATE kuwo wonke amathebula kusizindalwazi esichaziwe.
- Faka izinguquko zemvume:
IZINDLELA ZOKUPHILA;
Ngokulandela lezi zinyathelo, ungakwazi ukusetha ngokushesha ama-akhawunti amasha njengoba idivayisi yakho noma izinhlelo zokusebenza ziwadinga. Vele uqiniseke ukuthi unikeza amalungelo amancane adingekayo kumsebenzisi ngamunye.
Ukunikezwa Kwezimvume
Uma usudale ama-akhawunti omsebenzisi, isinyathelo esilandelayo sokuphatha abasebenzisi ku-MySQL ukunikeza izimvume ezifanele. I-MySQL ihlinzeka ngamalungelo anhlobonhlobo ongawahlanganisa ukuze uchaze izindima:
| Ilungelo | Descripción |
|---|---|
| KONKE | Inikeza zonke izimvume ngaphandle kokuthi GRANT OPTION |
| KHETHA | Ivumela ukufunda idatha kusuka kumathebula/ukubukwa |
| BHALA | Ivumela ukufaka imigqa emisha kumathebula |
| QAPHELA | Ikuvumela ukuthi uguqule idatha ekhona kumathebula |
| SUSA | Ikuvumela ukuthi ususe imigqa kumathebula |
| DALA | Ikuvumela ukuthi udale okusha yolwazi, amathebula, ukubuka, njll. |
| DLULA | Ikuvumela ukuthi ususe yolwazi, amathebula, ukubuka, njll. |
Nansi indlela yokunikeza nokuhoxisa izimvume:
- Inikeza izimvume ngomyalo we-GRANT:
NIKEZA KHETHA, FAKA KU-database_name.table_name KU-'user_name'@'localhost';
- Hoxisa izimvume ngomyalo othi REVOKE:
HODLA ISIBUYEKEZO KU-database_name.table_name KUSUKA 'Igama_lomsebenzisi'@'localhost';
- Ibonisa izimvume zamanje yomsebenzisi:
BONISA IZIBONELELO ZOKUTHI 'igama lomsebenzisi'@'localhost';
Ngaso sonke isikhathi khumbula ukusebenzisa umgomo welungelo elincane futhi uhlole njalo izimvume ezinikeziwe. Lokhu kusiza ukugcina isizindalwazi sakho sivikelekile.
Ukuhlola Umsebenzi Womsebenzisi
Ukuqapha umsebenzi womsebenzisi kusizindalwazi sakho kuyisici esibalulekile sokuphathwa komsebenzisi ku-MySQL . Ngokuhlola, ungakwazi:
- Thola imisebenzi esolisayo noma engagunyaziwe
- Landelela izinguquko kudatha ebucayi
- Ukuthobela imithetho nezinqubomgomo zangaphakathi
- Lungiselela ukusebenza ngokuhlonza imibuzo engasebenzi kahle
I-MySQL inikeza amathuluzi namasu amaningana ukuze unike amandla ukuhlola:
- Nika amandla ukungena okuvamile ngenketho yokuqala -general_log=1
- Lungiselela i-plugin Yokuhlola ukuze ungene emicimbini yabasebenzisi
- Sebenzisa izibangeli ukulandelela izinguquko kumathebula abalulekile
- Hlela imisebenzi ukuze ubuyekeze amalogi futhi uthumele izexwayiso ngomsebenzi ongajwayelekile
- Isibonelo se-Audit trigger
DALA I-TRIGGER ngaphambi_kokuvuselela_isisebenzi
NGAPHAMBI KOKUTHUNYELWA KWAbasebenzi
EMQWENI NGAMUNYE
FAKA KU-Audit_log
SET isenzo = 'buyekeza',
umsebenzisi = CURRENT_USER(),
date_time = MANJE ();
Ngokuhlanganisa ukucwaninga kwamabhuku esu lakho lonke lokuphatha abasebenzisi be-MySQL, ungagcina ukuphepha nokuhambisana kwesizindalwazi sakho.
Izinqubomgomo Nezinqubo
Ukuqinisekisa ukuphathwa kwabasebenzisi okuhambisanayo nokuphumelela ku-MySQL , kubalulekile ukubhala phansi izinqubomgomo nezinqubo zakho. Amadokhumenti akho kufanele ahlanganise:
- Umbandela wokudala ama-akhawunti omsebenzisi amasha
- Amazinga amaphasiwedi avikelekile
- Izindima ezichazwe ngaphambilini nezimvume zezinhlobo ezahlukene zabasebenzisi
- Isheduli nezinqubo zokuhlolwa kwamabhuku okuvamile
- Uhlelo lokuphendula isigameko lwemisebenzi esolisayo
Ukuba nalezi zinqubomgomo zichazwe kahle futhi kukhulunywe ngazo kusiza:
- Ukugcina ukuziphendulela phakathi kwabaphathi besizindalwazi
- Ngena amalungu eqembu amasha ngokushesha
- Gwema ukudideka noma ukungahambisani nokuphathwa komsebenzisi
- Ukubonisa ukukhuthala uma kwenzeka kucwaningwa ezokuphepha
Ngakho-ke zinike isikhathi sokubhala nokugcina amadokhumenti akho okuphatha abasebenzisi be-MySQL esesikhathini . Kuzofaneleka umzamo wakho ngokuhamba kwesikhathi.
