1.先按照依赖，执行以下命令

sudo apt-get install devscripts debhelper libsnappy-dev

2.下载leveldb的源码，利用wget命令

wget https://github.com/google/leveldb/archive/v1.19.zip

3. 解压，利用unzip

unzip v1.19.zip &&cd leveldb-1.19/

4. 在leveldb-1.19目录中执行 “make”，编译好leveldb，会在当前目录生成一个目录“out-shared”

5. 执行一下命令

cd ../out-shared/
sudo mv libleveldb.* /usr/local/lib
cd ../include/
sudo cp -R leveldb /usr/local/include
sudo ldconfig
执行到此，leveldb安装完成，下面来测试一下（Python）

pip install leveldb

进入到ipython环境

import leveldb

db = leveldb.LevelDB('./db')

# single put
db.Put('hello','world')
print db.Get('hello')

# single delete
db.Delete('hello')
print db.Get('hello')

# multiple put/delete applied atomically,and committed to disk
batch = leveldb.WriteBatch()
batch.Put('hello','world')
batch.Put('hello again','world')
batch.Delete('hello')

db.Write(batch,sync = True)
