安裝 Memcached
安裝
直接安裝 Ubuntu 的 Memcached 套件
sudo apt-get install memcached
sudo apt-get install libmemcached-dev libmemcached11
設定 php 7 Memcached 套件
php 7 讀取 Memcached 的套件還是在開發版，沒辦法直接使用 apt-get 去完成安裝，所以我們要自行下載開發版套件去進行編譯安裝
安裝 php 7 套件編譯軟體
php7.0-dev 是為了執行 php7 的 phpize 而安裝的
sudo apt-get install pkg-config
sudo apt-get install php7.0-dev
下載 php Memcached 套件
git clone https://github.com/php-memcached-dev/php-memcached
切換開發版套件路徑
cd php-memcached
git checkout -b php7 origin/php7
編譯 php7 Memcached 套件
phpize
./configure
make
make test
sudo make install
設定載入 php7 memcached 套件
sudo vim /etc/php/7.0/cli/conf.d/20-memcached.ini
sudo vim /etc/php/7.0/fpm/conf.d/20-memcached.ini
在 20-memcached.ini 檔案內設定
extension=memcached.so
設定檔分別要在 cli 與 fpm 兩個地方
cli指的是 command line 的 php 執行擋fpm指的是 nginx 解析 php 的解譯器
記得兩邊都要設定
重新啟動 php7.0-fpm
重新啟動之後，在網頁部分可以用 phpinfo(); 確認看看有沒有看到 Memcached 套件
sudo service php7.0-fpm restart
查詢安裝結果
查詢 phpinfo Memcached 安裝結果
查詢 php command line Memcached 安裝結果
$ php -i | grep memcached
/etc/php/7.0/cli/conf.d/20-memcached.ini,
