ʻElua makahiki a me 4 lā mai koʻu kākau ʻana , akā,ʻaʻole i lōʻihi nā mea - ke hoʻololi nei nā mea a pau a me ka uluʻana, a ke ho'āʻo neiʻo HAProxy-WI e mālama i kēiaʻano. Nui nā hana i hana ʻia ma mua o ʻelua mau makahiki, a makemake wau e kamaʻilio e pili ana i nā loli nui i kēia manawa, no laila: hoʻokipa i ka "cat".

3. Loaʻa ke kākoʻo Nginx i kēia manawa! ʻO ka mea pōʻino, ʻaʻole hiki ke hoʻohui like me ka HAProxy ma muli o ka hiki ʻole o ka hōʻike ʻana i kāu ʻikepili i ka mana manuahi o Nginx, akā ʻo nā hana nui (hoʻoponopono, hoʻohālikelike a hoʻololi i nā configs, hana a hoʻokomo i nā lawelawe) o HAProxy-WI. loaʻa mau no Nginx.
4. Hiki iā ʻoe ke kau i ka nānā ʻana piha no HAProxy a me Nginx! Loaʻa iā ia nā: Grafana, Prometheus a me Nginx a me HAProxy exporters. ʻElua kaomi a hoʻokipa i nā dashboards!
5. Ma nā manaʻo i ka pou mua, ua haʻi ʻia iaʻu i nā manawa he nui ka hoʻohana ʻana i nā palapala bash e hoʻokomo i nā lawelawe e pana ana iā ʻoe iho i ka wāwae. ʻAe wau me lākou a ʻo ia ke kumu e hele ai ʻo 95% o nā hoʻonohonoho āpau i Ansible.

I kēia manawa , kahi demo o HAProxy-WI a hiki iāʻoe ke ho'āʻo i nā mea a pau iāʻoe iho a ma kahi e loaʻa ai kahi changelog. ʻAʻole makemake wale i ka "habro effect" e ʻoluʻolu, inā ʻaʻole wau he kikowaena nāwaliwali no ka pūnaewele a me ka demo.
