Yadda ake Kula da Ayyukan Nginx Amfani da Netdata akan CentOS 7

Netdata tushen buɗe ido ne na kyauta, mai daidaitawa, daidaitawa, wanda za'a iya daidaita shi, mai iya daidaitawa, kuma mai ƙarfi na ainihin lokacin da kayan aikin sa ido na lafiya don tsarin Linux, wanda ke tattarawa da hango awo. Yana aiki akan kwamfutoci, kwamfutoci na sirri, sabobin, na'urorin da aka saka, IoT, da ƙari.

Kayan aiki ne na kula da lafiya wanda ke ba ka damar sanya ido kan yadda tsarinka da aikace-aikacenku ko ayyuka kamar sabar yanar gizo ke aiki, ko dalilin da yasa suke jinkiri ko rashin ɗabi'a. Yana da matukar tasiri da inganci dangane da amfani da CPU da sauran albarkatun tsarin.

A cikin wannan labarin, zamuyi bayanin yadda ake saka idanu akan aikin sabar gidan yanar gizo na Nginx HTTP ta amfani da Netdata akan rarrabawar CentOS 7 ko RHEL 7.

A ƙarshen wannan jagorar, zaku iya kallon abubuwan gani na haɗin kai, buƙatu, matsayi, da ƙimar haɗin sabar yanar gizon ku ta Nginx.

1. Sabar RHEL 7 tare da Mafi ƙarancin shigarwa.
2. ngx_http_stub_status_module an kunna.

Mataki 1: Sanya Nginx akan CentOS 7

1. Farawa ta farko ta mai sarrafa fakitin YUM.

# yum install epel-release

Mataki 3: Sanya Netdata akan CentOS 7

8. Akwai rubutun harsashi mai layi daya da zaku iya amfani da shi don fara shigar da sabon sakin netdata daga ma'ajiyar github. Wannan rubutun zai sauke wani rubutun don gano distro Linux ɗinku kuma ya shigar da fakitin tsarin da ake buƙata don gina netdata; bayan haka kama sabbin fayilolin tushen netdata; ginawa da shigar da shi.

Yi amfani da umarnin da ke ƙasa don ƙaddamar da rubutun kickstarter, zaɓi duk yana ba da damar shigar da fakitin da ake buƙata don duk plugins na netdata gami da na Nginx.

Idan ba ku shiga tsarin a matsayin tushen ba, za a sa ku shigar da kalmar sirri ta mai amfani don umarnin sudo, sannan kuma za a umarce ku da ku tabbatar da wasu ayyuka ta danna [Enter].

8. Bayan ginawa, da shigar da netdata, rubutun zai fara aikin netdata ta atomatik ta hanyar mai sarrafa sabis, kuma yana ba shi damar farawa a boot boot. Netdata yana sauraron tashar jiragen ruwa 19999 ta tsohuwa.

9. Na gaba, buɗe tashar jiragen ruwa 19999 a cikin Tacewar zaɓi don samun damar UI na yanar gizo na netdata.

# firewall-cmd --permanent --add-port=19999/tcp

Shi ke nan! Netdata shine ainihin-lokaci, aikin da aka rarraba da kayan aikin sa ido na lafiya don tsarin Linux. A cikin wannan labarin, mun nuna yadda ake saka idanu akan aikin sabar gidan yanar gizo ta Nginx ta amfani da netdata akan CentOS 7. Yi amfani da sigar sharhi da ke ƙasa don raba duk wata tambaya ko tunani game da wannan jagorar.
