This article mainly introduces how to achieve Ceph librdos programming access, has a certain reference value, interested friends can refer to, I hope you have a lot of gains after reading this article, the following let Xiaobian take you to understand.

introduction

I need to do direct programmatic access to Ceph's object store to see the performance difference with and without a gateway. The gate-way-based access example has gone through. What we're testing now is not going to go through the gateway, but using librados to deal directly with Ceph clusters.

environment configuration

1. Ceph cluster: You need to have a configured Ceph cluster, and you can see the state of the cluster through ceph -s.

2. Installation of development libraries My system is CentOS 6.5 Use the following command to install the relevant development package (C/C++ development package)

sudo yum install librados2-devel

After successful installation, you can see the corresponding header file under the/usr/include/rados path

sample program

The example program comes from the official website, can refer to the official website example

#include #include #include int main(int argc, const char **argv){int ret = 0 ;// Get cluster handle and connect to clusterstd::cout
