环境配置
操作系统 centos 5.8 hadoop版本cloudera cdh3u3 hbase版本hbase-0.90.4-cdh3u3 php版本5.2
1. 下载并编译thrift
# wget http://ftp.tc.edu.tw/pub/Apache/thrift/0.8.0/thrift-0.8.0.tar.gz
安装所需的依赖包
# yum install automake libtool flex bison pkgconfig gcc-c++ boost-devel libevent-devel zlib-devel python-devel ruby-devel php php-devel
# tar zxvf thrift-0.8.0.tar.gz
# cd thrift-0.8.0
# ./configure --prefix=/home/thrift --with-php-config=/usr/bin/php-config
# make && make install
2 生成php和hbase的接口文件:
# cd /home/thrift/
# bin/thrift --gen php $HBASE_HOME/src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thrift
# cd gen-php/Hbase
# ls
Hbase.php Hbase_types.php
3. 把PHP客户端需要的包及刚才生成的接口文件复制出来供php程序调用:
# mkdir -p /var/www/html/hbasethrift/libs (/var/www/html为apache的web主目录)
# cp -a /home/soft/thrift-0.8.0/lib/php/src /var/www/html/hbasethrift/libs
# mkdir -p /var/www/html/hbasethrift/libs/packages
# cp -a /home/thrift/gen-php/Hbase /var/www/html/hbasethrift/libs/packages
4. 启动hbase thrift server,测试php连接hbase
# ./bin/hbase-daemon.sh start thrift
hbase thrift 默认监听端口为9090
测试php连接与操作hbase代码
# vi hbasethrift.php

通过浏览器访问http://localhost/hbasethrift/hbasethrift.php,如果显示hbase中的表名与新建表table1 ,说明连接成功。
