ma mua o kaChen WeiliangUa kaʻana like ka moʻomanaʻoCentOS 6 Aʻo e hoʻokomo a hoʻonohonoho iā Monit ▼
Eia naʻe, i ka hoʻonohonoho CentOS 7Ka nānā ʻana i ka monitʻAʻole like ka papahana, me kekahi mau ʻokoʻa mai CentOS 6.
inā kāuLinuxHoʻohana ka mea hoʻokipa i ka ʻōnaehana CentOS 7. Ma hope o ka hoʻokomo ʻana iā Monit ma ka panel Vesta CP, hiki iā ʻoe ke hahai i kēia kumu aʻo e hoʻonohonoho i ka polokalamu nānā Monit.
lawelawe kaʻina hana nānā monit
Eia ka maʻiʻo hoʻonohonoho hoʻonohonoho lawelawe o ke kaʻina nānā Monit (hoʻopau i kekahi mau lawelawe nānā i hoʻohana ʻole ʻia):

- httpd
-
memcached - mysql
- nginx

E nānā i nā wahi a me nā inodes -
Nānā i nā kumuwaiwai ʻōnaehana (RAM, swap, CPU, load)
ʻO ka hoʻonohonoho nānā ʻana i ka monit
ʻOkoʻa nā inoa faila hoʻonohonoho Monit no CentOS 6 & 7:
- ʻO ka inoa o ka faila hoʻonohonoho Monit no CentOS 6 ʻo "monit.conf"
- ʻO ka inoa o ka faila hoʻonohonoho Monit no CentOS 7 ʻo "monitrc"
me SFTP ʻŌnaehanaMa hope o kou komo ʻana i kāu kikowaena Linux, hoʻoponopono i ka faila hoʻonohonoho Monit ▼
