實驗軟體

libevent-1.4.14b-stable.tar.gz

memcached-1.4.15.tar.gz

軟體安裝

yum install -y gcc gcc-c++  libstdc++-* zlib*

tar zxvf libevent-1.4.14b-stable.tar.gz

cd libevent-1.4.14b-stable

./configure --prefix=/usr/local/libevent/

make  &&  make install 

ln -s/usr/local/libevent/lib/libevent-1.4.so.2 /lib/libevent-1.4.so.2

tar zxvf memcached-1.4.15.tar.gz

cd  memcached-1.4.15

./configure  --prefix=/usr/local/memcached/ --with-libevent=/usr/local/libevent/

/usr/local/bin/memcached -d -m 1024 -u root -p 11211 -P /tmp/memcached.pid 啟動服務

-d選項是啟動一個守護程序，

-m是配置設定給Memcache使用的記憶體數量，機關是MB，我這裡是100MB，

-u是運作Memcache的使用者，我這裡是root，  

-l是監聽的伺服器IP位址，如果有多個位址的話，我這裡指定了伺服器的IP位址192.168.1.128

-p是設定Memcache監聽的端口，我這裡設定了11211，最好是1024以上的端口，我們這裡統一使用11211

-c選項是最大運作的并發連接配接數，預設是1024，我這裡設定了256，按照你伺服器的負載量來設定

-P是設定儲存Memcache的pid檔案，我這裡是儲存在/tmp/memcached.pid，
