🥇Tibgħat ta' zkuk json Nginx bl-użu ta' Vector għal Clickhouse u Elasticsearch

Vector, iddisinjat biex jiġbor, jittrasforma u jibgħat dejta tal-log, metriċi u avvenimenti.

Billi hija miktuba fil-lingwa Rust, hija kkaratterizzata minn prestazzjoni għolja u konsum baxx ta 'RAM meta mqabbla mal-analogi tagħha. Barra minn hekk, tingħata ħafna attenzjoni lill-funzjonijiet relatati mal-korrettezza, b'mod partikolari, l-abbiltà li tissejvja avvenimenti mhux mibgħuta f'buffer fuq disk u ddawwar fajls.

Arkitetturalment, Vector huwa router tal-avvenimenti li jirċievi messaġġi minn wieħed jew aktar sorsi, b'għażla li tapplika fuq dawn il-messaġġi trasformazzjonijiet, u tibgħathom lil wieħed jew aktar drenaġġ.

Vector huwa sostitut għal filebeat u logstash, jista 'jaġixxi fiż-żewġ rwoli (jirċievi u jibgħat zkuk), aktar dettalji dwarhom Online.

Jekk f'Logstash il-katina hija mibnija bħala input → filtru → output allura fil-Vector hija sorsi → jittrasforma → sinkijiet

Eżempji jistgħu jinstabu fid-dokumentazzjoni.

Din l-istruzzjoni hija struzzjoni riveduta minn Vyacheslav Rakhinsky. L-istruzzjonijiet oriġinali fihom l-ipproċessar tal-geoip. Meta ttestja geoip minn netwerk intern, vector ta żball.

Aug 05 06:25:31.889 DEBUG transform{name=nginx_parse_rename_fields type=rename_fields}: vector::transforms::rename_fields: Field did not exist field=«geoip.country_name» rate_limit_secs=30

Jekk xi ħadd irid jipproċessa geoip, imbagħad irreferi għall-istruzzjonijiet oriġinali minn Vyacheslav Rakhinsky.

Aħna ser tikkonfigura l-kombinazzjoni ta 'Nginx (logs ta' aċċess) → Vector (Klijent | Filebeat) → Vector (Server | Logstash) → separatament f'Clickhouse u separatament f'Elasticsearch. Se ninstallaw 4 servers. Għalkemm tista' tevitaha bi 3 servers.

L-iskema hija xi ħaġa bħal din.

Itfi Selinux fuq is-servers kollha tiegħek

sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
reboot

Aħna ninstallaw emulatur ta 'server HTTP + utilitajiet fuq is-servers kollha

Bħala emulatur ta 'server HTTP se nużaw nodejs-stub-server minn Maxim Ignatenko

Nodejs-stub-server m'għandux rpm. Hawnhekk toħloq rpm għaliha. rpm se jiġu kkompilati bl-użu Fedora Copr

Żid ir-repożitorju antonpatsev/nodejs-stub-server

yum -y install yum-plugin-copr epel-release
yes | yum copr enable antonpatsev/nodejs-stub-server

Installa nodejs-stub-server, benchmark Apache u multiplexer tat-terminal tal-iskrin fuq is-servers kollha

yum -y install stub_http_server screen mc httpd-tools screen

Ikkoreġejt il-ħin tar-rispons stub_http_server fil-fajl /var/lib/stub_http_server/stub_http_server.js sabiex kien hemm aktar zkuk.

var max_sleep = 10;

Ejja nniedu stub_http_server.

systemctl start stub_http_server
systemctl enable stub_http_server

Installazzjoni Clickhouse fuq is-server 3

ClickHouse juża s-sett ta' struzzjonijiet SSE 4.2, għalhekk sakemm ma jkunx speċifikat mod ieħor, l-appoġġ għalih fil-proċessur użat isir rekwiżit tas-sistema addizzjonali. Hawn hu l-kmand biex tivverifika jekk il-proċessur attwali jappoġġjax SSE 4.2:

grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"

L-ewwel trid tikkonnettja r-repożitorju uffiċjali:

sudo yum install -y yum-utils
sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64

Biex tinstalla pakketti trid tmexxi l-kmandi li ġejjin:

sudo yum install -y clickhouse-server clickhouse-client

Ħalli clickhouse-server jisma' l-karta tan-netwerk fil-fajl /etc/clickhouse-server/config.xml

<listen_host>0.0.0.0</listen_host>

Nibdlu l-livell tal-illoggjar minn traċċa għal debug

debug

Issettjar tal-kompressjoni standard:

min_compress_block_size  65536
max_compress_block_size  1048576

Biex tattiva l-kompressjoni Zstd, ġie avżat li ma tmissx il-konfigurazzjoni, iżda pjuttost li tuża DDL.

Ma stajtx insib kif nuża l-kompressjoni zstd permezz ta 'DDL fil-Google. Allura ħallejtha kif inhu.

Kollegi li jużaw kompressjoni zstd fi Clickhouse, jekk jogħġbok jaqsmu l-istruzzjonijiet.

Biex tibda s-server bħala daemon, mexxi:

service clickhouse-server start

Issa ejja ngħaddu għat-twaqqif ta' Clickhouse

Mur Clickhouse

clickhouse-client -h 172.26.10.109 -m

172.26.10.109 — IP tas-server fejn huwa installat Clickhouse.

Ejja noħolqu database tal-vettur

Installazzjoni ta' elasticsearch fuq ir-4 server biex tibgħat l-istess data lil Elasticsearch għal tqabbil ma' Clickhouse

Żid ċavetta pubblika rpm

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Ejja noħolqu 2 repo:

Installa elasticsearch u kibana

yum install -y kibana elasticsearch

Peress li se tkun f'kopja waħda, trid iżżid dan li ġej mal-fajl /etc/elasticsearch/elasticsearch.yml:

discovery.type: single-node

Sabiex dak il-vettur jista 'jibgħat data lil elasticsearch minn server ieħor, ejja nbiddlu network.host.

network.host: 0.0.0.0

Biex tikkonnettja ma' kibana, ibdel il-parametru server.host fil-fajl /etc/kibana/kibana.yml

server.host: "0.0.0.0"

Qadim u inkludi elasticsearch f'autostart

systemctl enable elasticsearch
systemctl start elasticsearch

u kibana

systemctl enable kibana
systemctl start kibana

Konfigurazzjoni ta' Elasticsearch għall-modalità ta' nodu wieħed 1 shard, 0 replika. X'aktarx li jkollok raggruppament ta 'numru kbir ta' servers u m'għandekx bżonn tagħmel dan.

Għal indiċi futuri, aġġorna l-mudell default:

Не забудте добавить юзера vector в нужную группу что бы он мог читать log файлы. Например, nginx в centos создает логи с правами группы adm.

usermod -a -G adm vector

Ejja nibdew is-servizz vector

systemctl enable vector
systemctl start vector

Iz-zkuk tal-vector jistgħu jarawh hekk:

journalctl -f -u vector

Għandu jkun hemm daħla bħal din fir-zkuk

INFO vector::topology::builder: Healthcheck: Passed.

Ittestjar tal-istress

Aħna nwettqu l-ittestjar bl-użu ta 'benchmark Apache.

Il-pakkett httpd-tools ġie installat fuq is-servers kollha

Nibdew nittestjaw bl-użu ta 'benchmark Apache minn 4 servers differenti fl-iskrin. L-ewwel, inniedu l-multiplexer tat-terminal tal-iskrin, u mbagħad nibdew nittestjaw bl-użu tal-benchmark Apache. Kif taħdem bl-iskrin tista' ssib ġo artikolu.
