一、LNMMP
LNMMP環境是Linux + Nginx + Memcached + MySQL + PhP,即LNMP + memcached。
Memcached 是一個高性能的分佈式內存對象緩存系統,用於動態Web應用以減輕數據庫負載。它通過在內存中緩存數據和對象來減少讀取數據庫的次數,從而提供動態、數據庫驅動網站的速度。Memcached基於一個存儲鍵/值對的hashmap。其守護進程(daemon )是用C寫的,但是客戶端可以用任何語言來編寫,並通過memcached協議與守護進程通信。

// 爲root用戶設置密碼 mysql> FLUSH PRIVILEGES; |
五、安裝php服務器
1.解決開發環境和依賴關係

4.爲php-fpm提供腳本,並將其添加到服務列表
# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm # chmod +x /etc/rc.d/init.d/php-fpm # chkconfig --add php-fpm # chkconfig php-fpm on
5.爲php-fpm提供配置文件
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
6.編輯php-fpm配置文件

7.啓動php-fpm
# service php-fpm start # ps -aux | grep php-fpm
六、安裝php加速器xcache
1.安裝xcache
1 2 3 4 5 6 7 8 9 10 | # tar xf xcache-3.0.3.tar.gz # cd xcache-3.0.3 # /usr/local/php/bin/phpize
//phpize 是用來安裝php擴展模塊的,通過phpize可以建立php的 外掛模塊,若你想在原來編譯好的php中加入memcached或者 ImageMagick等擴展模塊,就需要使用phpize # # ./configure --enable=xcache --with-php-config=/usr/local/php/bin/
php-config # make && make install
// 顯示xcache模塊路徑: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/ |

3.重啓php-fpm
# service php-fpm restart
七、配置nginx
1.編輯/etc/nginx/nginx.conf,實現動靜分離
worker_processes 2; #worker進程的個數 error_log /var/log/nginx/error.log notice; #錯誤日誌路徑及級別 events { worker_connections 1024; #每個worker能夠併發響應的最大請求數 } http { include mime.types; #支持多媒體類型 default_type application/octet-stream; sendfile on; #由內核直接轉發 #keepalive_timeout 0; keepalive_timeout 5; #持久連接5s gzip on; #開啓壓縮功能 server { listen 80; server_name www.hoo.com; add_header X-via $server_addr; #讓客戶端能夠看到代理服務器的IP location / { root html; index index.php index.html index.htm; } location ~* \.(jpg|jpeg|png|gif|js|css)$ { #匹配靜態內容 root html; #默認目錄在/usr/local/nginx/html } location ~ \.php$ { #匹配動態php文件 root html; fastcgi_pass 172.16.7.11:9000; #代理到的服務器 fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME scripts$fastcgi_script_name; include fastcgi_params; } } }
2.編輯/etc/nginx/fastcgi_params
fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name;
3.重載nginx
# service nginx reload
八、安裝Memcached服務器
1.memcached特性
Memcached是一款開發工具,它既不是一個代碼加速器,也不是數據庫中間件。其設計哲學思想主要反映在如下方面:
(1)簡單key/value存儲:服務器不關心數據本身的意義及結構,只要是可序列化數據即可。存儲項由“鍵、過期時間、可選的標誌及數據”四個部分組成;
(2)功能的實現一半依賴於客戶端,一半基於服務器端:客戶負責發送存儲項至服務器端、從服務端獲取數據以及無法連接至服務器時採用相應的動作;服務端負責接收、存儲數據,並負責數據項的超時過期;
(3)各服務器間彼此無視:不在服務器間進行數據同步;
(4)O(1)的執行效率
(5)清理超期數據:默認情況下,Memcached是一個LRU緩存,同時,它按事先預訂的時長清理超期數據;但事實上,memcached不會刪除任何已緩存數據,只是在其過期之後不再爲客戶所見;而且,memcached也不會真正按期限清理緩存,而僅是當get命令到達時檢查其時長;
2.安裝memcached
a).部署開發環境,解決依賴關係
# yum groupinstall "Development Tools" "Server Platform Deveopment" -y # yum install -y libevent-devel
b).編譯安裝memcached
# tar xf memcached-1.4.15.tar.gz # cd memcached-1.4.15 # ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent # make && make install
c).爲memcached提供啓動腳本
#!/bin/bash # # Init file for memcached # # chkconfig: - 86 14 # description: Distributed memory caching daemon # # processname: memcached # config: /etc/sysconfig/memcached . /etc/rc.d/init.d/functions ## Default variables PORT="11211" USER="nobody" MAXCONN="1024" CACHESIZE="64" OPTIONS="" RETVAL=0 prog="/usr/local/memcached/bin/memcached" desc="Distributed memory caching" lockfile="/var/lock/subsys/memcached" start() { echo -n $"Starting $desc (memcached): " daemon $prog -d -p $PORT -u $USER -c $MAXCONN -m $CACHESIZE -o "$OPTIONS" RETVAL=$? [ $RETVAL -eq 0 ] && success && touch $lockfile || failure echo return $RETVAL } stop() { echo -n $"Shutting down $desc (memcached): " killproc $prog RETVAL=$? [ $RETVAL -eq 0 ] && success && rm -f $lockfile || failure echo return $RETVAL } restart() { stop start } reload() { echo -n $"Reloading $desc ($prog): " killproc $prog -HUP RETVAL=$? [ $RETVAL -eq 0 ] && success || failure echo return $RETVAL } case "$1" in start) start ;; stop) stop ;; restart) restart ;; condrestart) [ -e $lockfile ] && restart RETVAL=$? ;; reload) reload ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $0 {start|stop|restart|condrestart|status}" RETVAL=1 esac exit $RETVAL
d).添加memcached至服務列表
# chmod +x /etc/init.d/memcached # chkconfig --add memcached # service memcached start
e).檢查是否運行
# ss -tnlp | grep 11211
九、安裝php的memcached擴展
1.安裝memcached擴展
# tar xf memcache-2.2.7.tgz # cd memcache-2.2.7 # /usr/local/php/bin/phpize # ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache # make && make install
2.編輯配置文件,整合php + memcached
# vim xcache.ini //添加模塊路徑 extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/memcache.so
3.重啓php-fpm
# service php-fpm restart
4.對memcached功能進行測試,在網站目錄中建立測試頁面test.php
//php服務器 # vim test.php <?php $mem = new Memcache; $mem->connect("172.16.1.13", 11211) or die("Could not connect"); $version = $mem->getVersion(); echo "Server's version: ".$version."<br/>\n"; $mem->set('hellokey', 'Hello World', 0, 600) or die("Failed to save data at the memcached server"); echo "Store data in the cache (data will expire in 600 seconds)<br/>\n"; $get_result = $mem->get('hellokey'); echo "$get_result is from memcached server."; ?> ~
測試訪問即可。
5.安裝wordpress測試訪問即可
十、安裝memadmin-master查看memcached狀態信息
1.解壓即可使用
//解壓至php服務器/usr/local/nginx/html/ # unzip memadmin-master.zip
2.測試訪問
