千家信息网最后更新 2024年09月27日php通过thrift操作hbase

环境配置

操作系统 centos 5.8 hadoop版本cloudera cdh4u3 hbase版本hbase-0.90.4-cdh4u3 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

php

require_once( $GLOBALS['THRIFT_ROOT'].'/Thrift.php' );
