Aerospike数据库实战(五) -- Aerospike C Client 开发

本人原创文章，转载请注明出处：http://blog.csdn.net/yanshu2012/article/details/54288856

1. C Client 安装

sudo yum install openssl-devel
sudo yum install gcc gcc-c++
wget -S "http://www.aerospike.com/artifacts/aerospike-client-c/3.1.18/aerospike-client-c-3.1.18.el6.x86_64.tgz"
tar -zxvf aerospike-client-c-3.1.18.el6.x86_64.tgz
sudo rpm -i aerospike-client-c-devel-3.1.18-1.el6.x86_64.rpm

2. 程序Makefile修改

3. key-Value Store API 开发代码实例
