        }
    }　　

　　5、安装php扩展
cd /tmp
tar zxvf /software/memcache-3.0.8.tgz -C /tmp
cd memcache-3.0.8  
/usr/local/php/bin/phpize  
./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir  
make
make install
vim /usr/local/php/etc/php.ini
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/"
extension=memcache.so
[Memcache]
memcache.allow_failover = 1
memcache.max_failover_attempts=20
memcache.chunk_size =8192　　

　　6、发布discuz
#解压目录
unzip /software/Discuz_X3.2_SC_UTF8.zip -d /discuz/
chmod -R 777 /discuz/
#开启memcache支持
vim /discuz/upload/config/config_global.php
$_config['memory']['memcache']['server'] = '10.13.106.31';
$_config['memory']['memcache']['port'] = 11211;
$_config['memory']['memcache']['pconnect'] = 1;
$_config['memory']['memcache']['timeout'] = 1;　　7、查看memcached状态
yum install -y telnet
telnet 10.13.106.31 11211
stats
STAT cmd_get 199
STAT cmd_set 37
STAT cmd_flush 0
STAT cmd_touch 0
