librados开发环境搭建

安装ceph环境：ceph 客户端配置_worker_program的博客-优快云博客

默认安装的话头文件位置为/usr/include/rados

安装成功配置好配置文件后

[root@bogon StorageMedia]# rados lspools
.rgw.root
default.rgw.control
default.rgw.meta
default.rgw.log
rdb
tmVideoPool
tmVideoDataPool
default.rgw.buckets.index
default.rgw.buckets.data
说明客户端连接配置正常，测试代码：

#include <rados/librados.hpp>
#include <iostream>
#include <string>
#include <list>
int main(int argc,  const  char  **argv)
{
   int ret  =  0 ;
   // Get cluster handle and connect to cluster
  std::string cluster_name("ceph");
  std::string user_name("client.admin");
  librados::Rados cluster ;
  cluster.init2(user_name.c_str(), cluster_name.c_str(),  0);
  cluster.conf_read_file("/etc/ceph/ceph.conf");
  cluster.connect();

   // Print the list of pools
  std::list<std::string> pools ;
  cluster.pool_list(pools );
  std::cout  <<  "List of pools from this cluster handle" << std::endl ;
  for (std::list<std::string>::iterator i = pools.begin(); i != pools.end(); ++i)
    std::cout << *i << std::endl;

   // Cleanup
  io_ctx.close();
  cluster.shutdown();

  return  0 ;
}

 编译命令：g++ -std=c++11 rados_test.cpp -lrados -o rados_test

[root@bogon test]# ./radio_test
