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-c⑶.1.18.el6.x86_64.tgz" 
tar -zxvf aerospike-client-c⑶.1.18.el6.x86_64.tgz 
sudo rpm -i aerospike-client-c-devel⑶.1.18⑴.el6.x86_64.rpm
Edit

2. 程序Makefile修改

  • 增加静态库援用: /usr/lib/libaerospike.a
  • 增加动态库援用: -lssl -lcrypto -lrt -ldl -lpthread -pthread
  • 增加头文件援用: /usr/include/aerospike
Edit

3. key-Value Store API 开发代码实例
