环境： ubuntu16.4 需要安装 snappy gflage bz2 zstd 以及g++ 其中zstd是facebook开放源代码里的压缩的库

git clone https://github.com/facebook/rocksdb.git

cd rocksdb

make static_lib 成功生成 librocksdb.a静太库(使用动态库，make share_lib)

cd examples/

测试 simple_example.cc 编译命令：

g++ simple_example.cc -o test -I ../include ../librocksdb.a -std=c++11 -lpthread -lrt -lsnappy -lgflags -lz -lbz2 -lzstd 成功后生成test可执行文件

./test

修改simple_example

}

再次编译，输出value value
