12 Jan 2015

0. memcache模块安装

step 1 下载memcache模块安装包

wget http://pecl.php.net/get/memcache-2.2.7.tgz
tar zxvf memcache-2.2.7.tgz
cd memcache-2.2.7

step 2 初始化php模块安装环境

/usr/local/php/bin/phpize
Configuring for:
PHP Api Version:         20131106
Zend Module Api No:      20131226
Zend Extension Api No:   220131226

step 3 编译安装memcache模块

./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-zts-20131226/

# 检查模块文件
ls /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
memcache.so  opcache.so

step 4 配置php.ini，添加安装的模块路径

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20131226/"
extension = memcache.so
# 或者
extension = /usr/local/php/lib/php/extensions/no-debug-zts-20131226/memcache.so

1. 扩展：安装守护进程memcached

wget http://memcached.org/files/memcached-1.4.22.tar.gz
tar zxvf memcached-1.4.22.tar.gz
yum install -y libevent-devel      
cd memcached-1.4.22
./configure --prefix=/usr/local/memcached
make
make install

# 启动memcached
# -d(作为daemon启动);-m(分配内存200M);-l(监听host);-p(端口);-u(执行user)
/usr/local/memcached/bin/memcached -d -m 200 -l localhost -p 11111 -u root
ps aux |grep 11111
root      4119  0.0  0.1  56492  1100 ?        Ssl  20:34   0:00 /usr/local/memcached/bin/memcached -d -m 200 -l localhost -p 11111 -u root
root      4126  0.0  0.0   4356   736 pts/0    S+   20:34   0:00 grep --color=auto 11111
