CentOS Webpanel (CWP7) da Monit monitoring dasturini qanday o'rnatish mumkin?

Ushbu qo'llanmada biz sizga qanday qilishni ko'rsatamizCentOs 7 da CentOS Webpanel (CWP7) o'rnatilishiMonitoring.

Monit monitoringi nima?

Monit monitoringi bepul va ochiq manba hisoblanadiDasturiy ta'minot, bu juda foydaliLinuxmonitoring dasturi.

• U UNIX/Linux-da server jarayonlarini, fayllarni, kataloglarni, nazorat summasi ruxsatlarini, fayl tizimlari va xizmatlarini avtomatik ravishda kuzatishi va boshqarishi mumkin.
• Masalan: Apache, Nginx,MySQL, FTP, SSH, Postfix va boshqalar ...
• Tizim ma'murlari uchun mukammal monitoring imkoniyatlarini ta'minlovchi tizimga asoslangan tizim boshqaruvi.

Nima uchun Monit monitoringini o'rnatish kerak?

To'xtash vaqtini kamaytirish uchun Monit monitoringidan foydalanishingiz mumkin, haElektron tijoratVeb-saytSEO和Internet-marketingyordamchi ta'sir ko'rsatadi.

Chunki har qanday xizmat ishlamay qolganda, Monit uni tekshiradi va xizmatni avtomatik ravishda ishga tushiradi.

Masalan: agar sizning Apache yoki Nginx xizmatingiz sababsiz ishlamay qolsa, monit tekshiradi va agar u ishlamay qolganligi aniqlansa, monit avtomatik ravishda tegishli xizmatlarni ishga tushiradi.

Qizig'i shundaki, monit o'zining httpd xizmatini boshqaradi.

Agar apache xizmatingiz ishlamay qolsa, monit o'z xizmati bilan ishlaydi.

1) Monit monitoring xizmati faylini yuklab oling▼

• Yuklab olish sahifasida Monit monitoring xizmati faylini bepul yuklab olish uchun oddiy yuklashda "Hozir yuklab olish" tugmasini bosing.
• (Kirish kodi: 5588)

2) Zipni oching va /etc/monit.d/ katalogiga yuklang.

• agar ichidaKonfiguratsiya faylini kuzatib boring /etc/monitrc da bir xil konfiguratsiyaga ega monitoring xizmati mavjud, u bo'lishi kerak在Konfiguratsiya faylini kuzatib boring /etc/monitrc o'chiriladi, aks holda xatolik yuz beradi.

Kerakli konfiguratsiya fayllarini yaratgandan so'ng, sintaksis xatolarini tekshiring▼

monit -t

Agar quyidagi so'rov paydo bo'lsa ▼

monit -t
/etc/monit.d/cwp.mariadbd:1: Service name conflict, mysql already defined '"/usr/sbin/mariadbd"'

• Bu shuni anglatadiki /etc/monit.d/cwp.mariadbd:1: Xizmat nomi ziddiyati; MySQL allaqachon aniqlangan '"/usr/sbin/mariadbd"'

Hech qanday xato bo'lmasa, monitoring xizmatini yoqing va qayta ishga tushiring ▼

systemctl enable monit
systemctl restart monit

Yuklashda Monit xizmatini ishga tushiring ▼

systemctl enable monit.service

Endi monitoring jurnalini tekshiring ▼

tail -f /var/log/monit.log

Monitoring asosiy buyruqlarini kuzatib boring

Monitni quyidagi buyruq bilan boshlang ▼

monit

Monit holatini tekshiring ▼

Monit xizmati doimo kuzatilmaydigan muammoni hal qiling

Monit barcha yoki muayyan xizmatlarning monitoringini yoqish va o'chirish uchun buyruqlarni o'z ichiga oladi.

Agar Monit xizmati doimo nazorat qilinmasa, siz quyidagi buyruqdan foydalanishingiz mumkin▼

monit monitor mysql

Yoki barcha monitoringni qayta yoqing▼

monit monitor all

• Ushbu buyruqlar ishlashi uchun Monit HTTP interfeysini yoqishingiz kerakligini unutmang.

Monit Notes

Monit jarayonlar xizmatlarini kuzatib boradi, ya'ni Monit tomonidan nazorat qilinadigan xizmatlarni oddiy usullar yordamida to'xtatib bo'lmaydi, chunki to'xtatilgandan so'ng, Monit ularni qaytadan ishga tushiradi.

Monit tomonidan nazorat qilinadigan xizmatni to'xtatish uchun siz shunga o'xshash narsalarni ishlatishingiz kerakmonit stop nameBunday buyruq, masalan, nginx ni to'xtatish ▼

monit stop nginx

Monit tomonidan nazorat qilinadigan barcha xizmatlarni to'xtatish uchun quyidagi buyruqni kiriting▼

monit stop all

Monit monitoring dasturini o'chirish ▼

yum remove monit
