linux(ubuntu) memcache安装及php的memcache扩展安装

1.安装包准备
a.memcache的服务端

libevent : memcache服务安装需要的库
https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz
memcached : memcache服务安装源码(注意后面有'd')
http://memcached.org/
b.memcahe的php扩展

libmemcached : 扩展库
http://libmemcached.org/libMemcached.html
memcached : php连接memcache的扩展安装源码(在http://pecl
4000
.php.net/中有3种php-memcache扩展，我们选择一直在维护的memcached,要注意版本选择，不能盲目选择最新的版本，要根据自己php的版本进行选择。我的php版本时5.6.9,所以选择了2.1.0版的memcached)
http://pecl.php.net/package-search.php?pkg_name=memcache&bool=AND&submit=Search
2.安装
a.安装libevent
tar xvf libevent-xxx

cd libevent-xxx

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

make

make install

b.安装memcached服务
tar xvf memcached-xxx

cd memcached-xxx

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

make

make install

启动memcached:/usr/local/memcached/bin/memcached -d -m 50 -u root -p 12000 -c 256 -P /tmp/memcached.pid

注:
-d选项是启动一个守护进程，
-m是分配给Memcache使用的内存数量，单位是MB.
-u是运行Memcache的用户.
-l是监听的服务器IP地址,我这里没有填.
-p是设置Memcache监听的端口.
-c选项是最大运行的并发连接数,默认是1024,按照你服务器的负载量来设定.
-P是设置保存Memcache的pid文件.

检查memcache是否启动成功:ps aux | grep memcached

c.安装libmemcached库

tar xvf libmemcached-xxx

cd libmemcached-xxx

./configure --prefix=/usr/local/libmemcached --with-memcached=/usr/local/memcached/bin/memcached

make

make install

d.安装php的memcached扩展

tar xvf memcached-xxx

cd memcached-xxx

/usr/local/php/bin/phpize:你的php安装目录下的bin目录中的phpize命令

./configure --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached

make

make install

配置php.ini文件:
extension=扩展安装成功后显示的路径/memcached.so

重启php服务

查看扩展是否安装成功:php -m | grep memcache
