Wụnye Varnish Cache 5.2 iji kwalite arụmọrụ Apache na CentOS 7
Cache Varnish (nke a na-akpọkarị Varnish), bụ isi mmalite mepere emepe, onye na-eme ngwa ngwa proxy HTTP ezubere maka ịgbasa sava weebụ ọsọ ọsọ. A na-eme ya maka njedebe njedebe API nke a na-ejikarị eme ihe yana kwa maka saịtị dị ike nke na-enye nnukwu ọdịnaya ma nwee ahụmahụ dị elu.
Ọ bụ isi na-enyere aka belata ibu CPU; na-akwado nguzozi ibu na sava weebụ ma na-enyere ihe nchọgharị weebụ aka ibuo saịtị ngwa ngwa n'ihi ịchekwa cache na RAM. Ọtụtụ nnukwu ụlọ ọrụ na-eji ya gụnyere Facebook, Twitter, na Wikipedia naanị ịkọ ma ole na ole.
- CentOS 7 nwere Apache arụnyere
- CentOS 7 nwere adreesị IP kwụ ọtọ
N'isiokwu a, m ga-akọwa otu esi etinye ma jiri Varnish Cache 6.5 dị ka njedebe n'ihu na sava weebụ Apache na CentOS 7 (na-arụkwa ọrụ na RHEL 7).
Kwụpụ 1: Wụnye sava weebụ Apache na CentOS 7
1. Buru ụzọ wụnye sava Apache HTTP site na ebe nchekwa ngwanrọ CentOS ndabara site na iji njikwa ngwugwu YUM dị ka ndị a.
# yum install httpd
2. Ozugbo Apache arụnyere, malite ya maka oge ahụ ma mee ka ọ malite na-akpaghị aka na buut usoro.
# systemctl start httpd # systemctl enable httpd # systemctl status httpd
3. Ọzọ update usoro firewall iwu ikwe inbound ngwugwu na ọdụ ụgbọ mmiri 80 iji iwu n'okpuru.
# firewall-cmd --zone=public --permanent --add-service=http # firewall-cmd --reload
Kwụpụ 2: Wụnye Cache Varnish na CentOS 7
4. Ugbu a enwere ngwugwu RPM achịkọtara nke ọma maka ụdị Varnish Cache 6 kachasị ọhụrụ (ya bụ 6.5 n'oge ederede), yabụ ịkwesịrị ịgbakwunye ebe nchekwa Varnish Cache gọọmentị.
Tupu nke ahụ, ịkwesịrị ịme ka ebe nchekwa EPEL rụnye ọtụtụ ngwugwu ndabere dịka egosiri.
# yum install -y epel-release
5. Na-esote, wụnye pygpgme, ngwugwu maka ijikwa akara GPG na yum-utils, nchịkọta ọrụ bara uru nke na-agbatị njirimara ala yum n'ụzọ dị iche iche.
# yum install pygpgme yum-utils
6. Ugbu a mepụta faịlụ aha ya bụ /etc/yum.repos.d/varnishcache_varnish65.repo nke nwere nhazi nhazi n'okpuru.
# vi /etc/yum.repos.d/varnishcache_varnish65.repo
Ihe dị mkpa: Gbaa mbọ hụ na iji nkesa na ụdị Linux gị dochie el na 7 na nhazi dị n'okpuru:
[varnishcache_varnish65] name=varnishcache_varnish65 baseurl=https://packagecloud.io/varnishcache/varnish65/el/7/$basearch repo_gpgcheck=1 gpgcheck=0 enabled=1 gpgkey=https://packagecloud.io/varnishcache/varnish65/gpgkey sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300 [varnishcache_varnish65-source] name=varnishcache_varnish65-source baseurl=https://packagecloud.io/varnishcache/varnish65/el/7/SRPMS repo_gpgcheck=1 gpgcheck=0 enabled=1 gpgkey=https://packagecloud.io/varnishcache/varnish65/gpgkey sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300
7. Ugbu a na-agba ọsọ iwu n'okpuru ka imelite gị local yum cache na wụnye varnish cache ngwugwu (echefula ịnakwere igodo GPG site na ịpị y ma ọ bụ ee mgbe ị na-etinye ya ngwugwu):
# yum -q makecache -y --disablerepo='*' --enablerepo='varnishcache_varnish65' # yum install varnish
8. Mgbe ị wụnye Varnish Cache, a ga-arụnye isi ọrụ dị ka/usr/sbin/varnished na varnish nhazi faịlụ dị na /etc/varnish/:
- /etc/varnish/default.vcl – nke a bụ isi faịlụ nhazi varnish, ejiri asụsụ nhazi vanish (VCL) dee ya.
9. Ugbu a bido ọrụ varnish, mee ka ọ malite na-akpaghị aka n'oge buut sistemu, ma nyochaa ọnọdụ ya iji hụ na ọ na-agba ọsọ dị ka ndị a.
# systemctl start varnish # systemctl enable varnish # systemctl status varnish
10. Ị nwere ike ikwenye na nrụnye Varnish gara nke ọma site n'ịhụ ebe Varnish executable na ụdị arụnyere na usoro gị.

Kwụpụ 3: Hazie Apache ka ọ rụọ ọrụ na Cache Varnish
11. Ugbu a hazie Apache ka ọ rụọ ọrụ na njikọ Varnish Cache. Site na ndabara Apache na-ege ntị na ọdụ ụgbọ mmiri 80, ịkwesịrị ịgbanwe ọdụ ụgbọ mmiri HTTPD ndabara na 8080 - nke a ga-ahụ na HTTPD na-aga n'azụ caching Varnish.
Ị nwere ike iji sed iwu ịgbanwe ọdụ ụgbọ mmiri 80 ka 8080 dị ka egosiri.
# sed -i "s/Listen 80/Listen 8080/" /etc/httpd/conf/httpd.conf
Mara: Ọzọkwa, ịkwesịrị ịgbanwe ọdụ ụgbọ mmiri na nhazi nhazi nnabata gị maka weebụsaịtị ọ bụla ịchọrọ ijere site na Varnish. Nke a bụ nhazi maka saịtị ule anyị (/etc/httpd/conf.d/tecmint.lan.conf).
<VirtualHost *:8080>
DocumentRoot "/var/www/html/tecmint.lan/"
ServerName www.tecmint.lan
# Other directives here
</VirtualHost>
12. Ọzọ, mepee faịlụ nhazi usoro varnish wee chọta parameter ExecStart nke na-akọwa ọdụ ụgbọ mmiri Varnish na-ege ntị, ma gbanwee uru ya site na 6081 gaa na 80 dị ka egosiri na nseta ihuenyo.
# systemctl edit --full varnish
Nhazi kwesịrị ịdị ka nke a mgbe emechara.
ExecStart=/usr/sbin/varnishd -a :80 -f /etc/varnish/default.vcl -s malloc,256m
13. Ọzọ, guzobe Apache dị ka ihe nkesa azụ maka Varnish proxy, na faịlụ nhazi /etc/varnish/default.vcl.
# vi /etc/varnish/default.vcl
Chọta ngalaba azụ azụ, ma kọwaa IP na ọdụ ụgbọ mmiri onye ọbịa. N'okpuru bụ nhazi ndabere ndabere, tọọ nke a ka ọ rụtụ aka na nkesa ọdịnaya gị n'ezie.
backend default {
.host = "127.0.0.1";
.port = "8080";
}
Ọ bụrụ na ihe nkesa azụ azụ gị na-agba ọsọ na sava dị iche nwere adreesị 10.42.1.10, mgbe ahụ paramita nnabata kwesịrị ịrụtụ aka na adreesị IP a.
backend server1 {
.host = "10.42.1.10";
.port = "8080";
}
14. Mgbe ịmechara nhazi niile dị mkpa, malitegharịa HTTPD na Varnish cache iji mee mgbanwe ndị dị n'elu.
# systemctl daemon-reload # systemctl restart httpd # systemctl restart varnish
Kwụpụ 4: Nwalee cache Varnish na Apache
15. N'ikpeazụ, nwalee, ma ọ bụrụ na Varnish na-enyere aka na-arụ ọrụ na HTTPD ọrụ site na iji cURL iwu n'okpuru, nke nwere ike iji na-ele HTTP nkụnye eji isi mee.
