Mā te ripa Āpitihanga koe e āhei ai ki te hono i tētahi pātengi raraunga PostgreSQL whakamanahinihia, i tētahi momo Redis whakamanahinihia rānei ki tētahi paetukutuku, me te kore e hanga, e tiaki rānei i tētahi tūmau mō taua mea. Mā KapsuleHost e whakarite, ka hoatu ki a koe tētahi aho hono, ā, ka tangohia mā runga anō i te horopaki marama ina whakakorehia e koe.
Kei Hea Ngā Āpitihanga
Whakatuwherahia Ngā Paetukutuku, pāwhiritia te paetukutuku, whakatuwherahia te rōpū Ngā Taupānga kei te tahua maui o te paetukutuku, kātahi ka kōwhiritia Ngā Tāpiritanga. Ko te taitara o te whārangi ko Ngā āpitihanga whakamanahinihia.
E rua ngā kōwhiringa kei roto i te rārangi hokohoko:
| Āpitihanga | Whakamahinga māori |
|---|---|
| PostgreSQL | Te pātengi raraunga matua mō tētahi tono kāore i runga i te MySQL |
| Redis | Te penapena tere (caching), te rokiroki wāhanga, me ngā rārangi mahi papamuri |
He mea wehe ēnei i te pātengi raraunga MySQL e haere tahi ana me tētahi paetukutuku tukutuku paerewa. Kei te ripa Putanga Raraunga taua mea, ā, kāore he whakaritenga e hiahiatia ana: tirohia Te Hono atu ki Tō Pātengi Raraunga mā roto i te Anga SSH.
Te Tono i Tētahi Āpitihanga
- Kimihia te āpitihanga kei roto i te wāhanga Tāpiri tētahi roputu āramatai.
- Pāwhiritia Tāpiri ki te paetukutuku.
Ka tuhia tonutia te tono, ā, ka puta te āpitihanga i roto i Ō āpitihanga me tētahi tohu PENDING me te kupu āpiti E tatari ana mō te kaiwhakarite. Ka whakahōu anō te whārangi ia tekau mā rima hēkona, nō reira ka taea e koe te waiho tuwhera.
I ia tekau meneti pea, ka mauria e tētahi mahi papamuri ngā tono e taria ana, ka hangaia he pātengi raraunga motuhake me tētahi kaiwhakamahi motuhake mō tō paetukutuku, ā, ka tuhia anō tētahi aho hono kua whakamunatia. Kātahi ka neke te tūnga ki ACTIVE.
Me whai whakaaetanga sites:write te tono, te tango rānei, i tētahi āpitihanga. Ka taea e ngā mema tīma pānui anake te kite i ngā āpitihanga kei konā me ō rātou tūnga, engari kua hunaia ngā pātene.
Kotahi o Ia Momo, Mō Ia Paetukutuku
Ka taea e tētahi paetukutuku te pupuri kotahi āpitihanga PostgreSQL me kotahi āpitihanga Redis. Ki te tonoa he tuarua o te momo ōrite, ka whakakāhoretia me tētahi karere e kī ana kua whakaritea kētia, ā, ka huna te rārangi hokohoko i tētahi kōwhiringa i muri i tōna whakaurunga. Ina kua whakaritea ngā mea e rua, ka kī te wāhanga rārangi hokohoko Kua whakaritea katoatia ngā āpitihanga e wātea ana.
Te Pānui i te Tūnga
| Tūnga | Tikanga |
|---|---|
| PENDING | Kua tonoa, e tatari ana i te rārangi mō te kaiwhakarite |
| PROVISIONING | E hangaia ana i tēnei wā |
| ACTIVE | Kua rite ki te whakamahi |
| FAILED | Kāore i oti te whakaritenga; ka whakaatuhia te take i runga i te rārangi |
| DELETED | Kua tangohia, kua kore e whakarārangihia |
Ka whakaatuhia e tētahi rārangi FAILED te kupu hapa pono kei raro iho, kaua ko tētahi karere whānui noa. Ki te kore e taea e koe te whakatika i te take, tāruatia ōrite ki roto i tētahi tiikete tautoko: tirohia Te Whakatuwhera i Tētahi Tiikete Tautoko.
Te Tiki i te Aho Hono
I te mea kua ACTIVE tētahi āpitihanga, ka whakaatu tōna rārangi i tētahi aho hono kua huna, kua whakakapia te kupuhipa ki ngā piko, nō reira ka taea e koe te whakaū i te kaihautū me te ingoa pātengi raraunga mā te tiro poto, me te kore e whakakitea te mōhiohio ngaro.
Pāwhiritia Kōphi hono hei tuku i te aho hono katoa ki tō papatopetope. Ka wetewetea i te taha tūmau mō taua tono kotahi anake, kāore anō i tāngia ki te whārangi, nō reira kāore e torere ana i roto i ngā tiritiri mata me ngā whakapae mata. Ka tuhia ia whakakitenga ki te rārangi arotake o te paetukutuku, ā, ka kitea i roto i te Rārangi Auaha Paetukutuku.
Kei roto te aho i te āhua URL māori mō ia pūnaha, e mau ana i te kaihautū, te tauranga, te kaiwhakamahi, te kupuhipa me te ingoa pātengi raraunga i hangaia mō tēnei paetukutuku.
Te Whakamahi i te Aho Hono ki Tō Tono
Whakapiritia te aho hono ki te wāhi e pānui ai tō tono i tōna whirihoranga. Mō tētahi paetukutuku Node.js, ko te wāhi tika ko te ripa Secrets, i raro i tētahi kī pērā i te DATABASE_URL, i te REDIS_URL rānei, i roto i te horopaki production.
Kaua e whakauru pūmau i te aho hono ki tētahi kōnae ka tāpaetia e koe. Kei roto he kupuhipa e mahi ana. Mēnā ka eke ki tētahi tāwhiti git, me whakaaro he mea kua torere, ā, ko te rongoā pono anake ko te muku i te āpitihanga me te tono anō i tētahi mea hōu, nā te mea kāore e taea te huri i te kupuhuna i te waahi tonu mai i te paewhakahaere.
Te Tango i Tētahi Āpitihanga
Pāwhiritia Delete i te rārangi. Ka pātai mai a KPanel kia whakaūngia, ā, ka tino mārama mai i ngā putanga: ka tangohia tēnei i te pātengi raraunga whakamanahinihia, ā, kāore e taea te whakaora i ngā raraunga.
Ka tohua te rārangi hei mea kua mukua i taua wā tonu, ā, ka tangohia e te kaiwhakarite te pātengi raraunga me te kaiwhakamahi i tōna wā e whai ake nei. Ka whakamutua ngā hononga kei te mahi i taua wā anō.
Kāore he tāwharau tuari i mauria mō tētahi āpitihanga whakamanahinihia i te wā e mukua ana, kāore anō he huri whakamuri. Mēnā kei roto tētahi mea e hiahia ana koe kia pupuri, tukuna ki waho i mua mā te whakamahi i te pg_dump, i te redis-cli --rdb rānei, i te mea e mahi tonu ana te āpitihanga, ā, e mahi tonu ana te aho hono.
Te Kōwhiri i waenga i ngā Kōwhiringa
Whakamahia a PostgreSQL ina hiahia tō tono i tētahi pātengi raraunga whakapā, ā, kua tuhia mō Postgres: he here kaha, he mahi tahi (transactions), he pou JSON, me te rapu kupu-katoa ka rāwaho atu te whakatinana.
Whakamahia a Redis mō ngā mea e whakaaetia ana kia ngaro: ngā kongakonga kua penatia, ngā tatau whakaiti-reiti, te rokiroki wāhanga, me ngā rārangi mahi. Me whakaaro he mea tere me te kore pūmau, kaua he pūnaha pūkete.
Whakamahia te pātengi raraunga MySQL kua whakaurua mai mō WordPress, mō ngā mea katoa kua tuhia kē mō MySQL. Ki te tāpiri koe i tētahi āpitihanga Postgres ki tētahi paetukutuku WordPress, kāore he hua, nā te mea kāore e taea e WordPress te kōrero ki a ia.
Te Whakatika Raru
Kua roa noa atu te āpitihanga e PENDING ana. Ka whakahaerehia te kaiwhakarite i runga i tētahi wātaka, kaua i te wā tonu. Waiho te whārangi kia tuwhera, i te mea ka whakahōu anō ia, ā, titiro anō ā muri ake. Mēnā kāore anō kia neke i muri i ētahi wā maha, whakatuwherahia tētahi tiikete tautoko me te rorohiko o te paetukutuku me te momo āpitihanga.
Kua FAILED te whakaritenga. Pānuitia te hapa kei te rārangi. Mukua te āpitihanga i rahua, ā, tonoa anō, he haumaru tēnei: kāore rawa he pātengi raraunga e mahi ana i muri i tētahi rārangi i rahua.
Kāore he aha e tupu ana i te Kōphi hono. Ka ārai ētahi pūtirotiro i te tuhinga papatopetope ina kāore te ripa e aro mai ana. Pāwhiritia te whārangi i te tuatahi, kātahi ka pāwhiritia anō te pātene.
Kāore e taea e te tono te hono. Tirohia ēnei mea e toru, kia tika te raupapa: kei te ACTIVE te tūnga āpitihanga, nāu anō i kōphi te aho kaua i te tā anō, ā, e pānui ana tō tono i te uara i tautuhia tūturutia e koe, kaua i tētahi mea tawhito nō tētahi tukunga o mua. He mea tika kia tīmata anō i mua i te tango o te whirihoranga hōu.
Kua whakakāhoretia ngā hononga i muri i te tuku anō. Whakaūngia kei te taurite tonu te aho hono kei tō whirihoranga me tērā kei tēnei whārangi. Mā te muku me te tono anō i tētahi āpitihanga ka hangaia he kaiwhakamahi hōu me tētahi kupuhipa hōu, nō reira kāore e mahi te aho tawhito.
Te Wāhi e Haere ai ā Muri Ake
- Te Penapena i ngā Kupu Ngaro Tono mō Tētahi Paetukutuku, te wāhi tika hei pupuri i te aho hono.
- Te Hono atu ki Tō Pātengi Raraunga mā roto i te Anga SSH mō te pātengi raraunga MySQL kua whakaurua mai.
- Ngā Tautuhinga Paetukutuku mō ētahi atu whirihoranga i te taumata paetukutuku.
