Memcached是個好東西 它可以?由于頁面是緩存在內(nèi)存里，所以減少了系統(tǒng)的I/O操作?？梢灾苯永肕emcached的分布式特性?？梢灾苯永镁彺娴倪^期時間，方便對頁面的過期時間進(jìn)行處理。
網(wǎng)上找了很多教程 都不適用于wordpress 于是我經(jīng)網(wǎng)上的腳本 自己改了一個
注意事項??！?memcached是多核處理的 如果你是單核的服務(wù)器 在配上這個 會相當(dāng)?shù)目?甚至?xí)礄C(jī) 我之前出過了很多問題 所以我現(xiàn)在僅能把教程寫出來 而我用了redis /哭;w;
Nginx內(nèi)置了Memcached模塊memcached_module
它可以從memcached中讀取內(nèi)容后直接輸出，后續(xù)的請求不再經(jīng)過如php-fpm、django應(yīng)用程序處理，大大的提升動態(tài)頁面的速度。nginx只負(fù)責(zé)從memcached中讀取數(shù)據(jù)，要往memcached寫入數(shù)據(jù)還得需要后臺的應(yīng)用程序來完成，主動的將要緩存的頁面緩存到memcached中，然后通過404重定向到后端去處理的。
memcached的key可以通過memcached_key變量來設(shè)置，如以$uri。如果命中，那么直接輸出內(nèi)容，沒有命中就意味著nginx需要從應(yīng)用程序請求頁面。同時，我們還希望該應(yīng)用程序?qū)㈡I值對寫入到memcached，以便下一個請求可以直接從memcached獲取。
如果鍵值不存在，nginx將報告not found錯誤。最好的方法是使用error_page指定和location請求處理。同時包含"Bad
Gateway"錯誤和"Gateway Timeout"錯誤，如：error_page 404 502 504 = @app;。

首先在nginx總配置中連接memcached 在http{ }字段中添加
#memcache servers load balanced
upstream memcached {
server 127.0.0.1:11211 weight=5 max_fails=3 fail_timeout=30s;
keepalive 1024;
}
#fastcgi - little load balancer
upstream phpbackend{
server 127.0.0.1:9000 weight=5 max_fails=5 fail_timeout=30s;
}
然后在網(wǎng)站中添加配置
網(wǎng)站-你的網(wǎng)站-設(shè)置-配置文件中 的 最后一個“}”前添加
client_body_timeout 1460;
client_header_timeout 1460;
send_timeout 1460;
client_max_body_size 10m;
keepalive_timeout 1300;
location /app/ { deny all; }
location /includes/ { deny all; }
location /lib/ { deny all; }
location /media/downloadable/ { deny all; }
location /pkginfo/ { deny all; }
location /report/config.xml { deny all; }
location /var/ { deny all; }
location ~* .(jpg|png|gif|css|js|swf|flv|ico)$ {
expires max;
tcp_nodelay off;
tcp_nopush on;
}
location / {
try_files $uri $uri/ @handler;
expires 30d;
}
location @handler {
rewrite / /index.php;
}
location ~ .php$ {
if (!-e $request_filename) {
rewrite / /index.php last;
}
expires off;
default_type text/html; charset utf-8;
if ($request_method = GET) {
set $memcached_key $request_uri;
memcached_pass memcached;
error_page 404 502 = @cache_miss;
add_header x-header-memcached true;
}
if ($request_method != GET) {
fastcgi_pass phpbackend;
}
}
location @cache_miss {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_max_temp_file_size 0;
fastcgi_pass 127.0.0.1:9000;
fastcgi_send_timeout 5m;
fastcgi_read_timeout 5m;
fastcgi_connect_timeout 5m;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 512k;
fastcgi_param PHP_VALUE "memory_limit = 32M";
fastcgi_param PHP_VALUE "max_execution_time = 18000";
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /. {
deny all;
}
這個是我改過的版本 理應(yīng)寶塔面板下的Wordpress都可以用
如果提示你 什么什么錯誤 那你應(yīng)該檢查一下 你的Nginx剛開始時是否是 編譯安裝方法 如果你是極速安裝的方法 請重裝成編譯安裝
