Optimizing WordPress with Nginx, Varnish, APC, W3 Total Cache

, , , , , , 0

Идеята е ясна – оптимизация на уордпрес блога чрез varnish който работи пред nginx-a с една едничка цел – по-бързо отваряне на сайта ни.

Първо инсталираме nginx и php-fpm :

apt-get install nginx php5-fpm

 

Ето и примерния ни nginx.conf:

user www-data;
worker_processes 12;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
worker_rlimit_nofile 8192;
events {
worker_connections 4096;
# multi_accept on;
}

http {
include /etc/nginx/mime.types;
# include /etc/nginx/proxy.conf;
include /etc/nginx/fastcgi.conf;
access_log /var/log/nginx/access.log;
upload_progress proxied 1m;
#cache
#fastcgi_cache_path /tmp/cache/fastcgi_cache levels=1:2 keys_zone=php:16m inactive=5m max_size=500m;
proxy_cache_path /var/www/cache/ levels=1:2 keys_zone=алабала.нет:10m inactive=30m max_size=2g;

upstream php5-fpm-sock {
server 127.0.0.1:9000 weight=100 max_fails=3 fail_timeout=5;
#server 127.0.0.1:9001 weight=100 max_fails=3 fail_timeout=5;
#server unix:/var/run/php5-fpm.sock;
}
#sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;

gzip on;
gzip_disable “MSIE [1-6]\.(?!.*SV1)”;
gzip_http_version 1.0;
gzip_comp_level 9;
gzip_proxied any;
gzip_min_length 1100;
gzip_buffers 16 8k;
gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
server_tokens on;
server_name_in_redirect off;

}

След това е нужно да създадем виртуален хост за сайта ни – /etc/nginx/sites-enabled/виртуален-хост.лтд

listen 8080;

Така , след всичко това трябва да имаме работещ nginx на порт 8080 , от тук нататък идва ред на Varnish.
Първо го инсталираме :

apt-get install varnish

 

Идват и настройките..
Правим си файл алабала.vcl в директория /etc/varnish/ и пействаме в него това:

backend default {
.host = "127.0.0.1";
.port = "8080";
}
acl purge {
"localhost";
}

sub vcl_recv {
if (req.request == “PURGE”) {
if (!client.ip ~ purge) {
error 405 “Not allowed.”;
}
return(lookup);
}
if (req.url ~ “^/$”) {
unset req.http.cookie;
}
}
sub vcl_hit {
if (req.request == “PURGE”) {
set obj.ttl = 0s;
error 200 “Purged.”;
}
}
sub vcl_miss {
if (req.request == “PURGE”) {
error 404 “Not in cache.”;
}
if (!(req.url ~ “wp-(login|admin)”)) {
unset req.http.cookie;
}
if (req.url ~ “^/[^?]+.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(\?.|)$”) {
unset req.http.cookie;
set req.url = regsub(req.url, “\?.$”, “”);
}
if (req.url ~ “^/$”) {
unset req.http.cookie;
}
}
sub vcl_fetch {
if (req.url ~ “^/$”) {
unset beresp.http.set-cookie;
}
if (!(req.url ~ “wp-(login|admin)”)) {
unset beresp.http.set-cookie;
}
}

След това отваряме /etc/default/varnish и закоментираме всичко като оставяме само :

START=yes

# Maximum number of open files (for ulimit -n)
NFILES=131072

# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory. If you increase log size,
# you need to increase this number as well
MEMLOCK=82000

# Default varnish instance name is the local nodename. Can be overridden with
# the -n switch, to have more instances on a single server.
INSTANCE=$(uname -n)
DAEMON_OPTS=”-a ИП.АДРЕСА.НИ:80 \
-T localhost:6082 \
-f /etc/varnish/алабала.vcl \
-S /etc/varnish/secret \
-s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G”

Следва инсталация на apc,memcached :

apt-get install apc memcached php5-memcached

След това инсталираме необходимия плугин за уордпрес -> W3-Total-Cache.
След успешна инсталация са необходими малки настройки.
Първо слагаме отметка на Page Cache,Minify – тук избираме : Minify mode – Manual , Minify Cache Method – Memcached , Object Cache – отметка , Browser Cache – отметка , Enable varnish cache purging – отметка и за сървър слагаме 127.0.0.1
Следва запаметяване и тест дали всичко работи. Конфигурациите са от моя сървър и с тях всичко работи чудесно 🙂
