## Build and Install
|
|
|
|
Create a workspace and checkout ledisdb source
|
|
|
|
mkdir $WORKSPACE
|
|
cd $WORKSPACE
|
|
git clone git@github.com:siddontang/ledisdb.git src/github.com/siddontang/ledisdb
|
|
|
|
cd src/github.com/siddontang/ledisdb
|
|
|
|
make
|
|
|
|
## LevelDB support
|
|
|
|
+ Install leveldb and snappy, if you have installed, skip.
|
|
|
|
LedisDB supplies a simple shell to install leveldb and snappy:
|
|
|
|
sh build_leveldb.sh
|
|
|
|
It will default install leveldb at /usr/local/leveldb and snappy at /usr/local/snappy.
|
|
|
|
LedisDB use the modified LevelDB for better performance, see [here](https://github.com/siddontang/ledisdb/wiki/leveldb-source-modification).
|
|
|
|
+ Set LEVELDB_DIR and SNAPPY_DIR to the actual install path in dev.sh.
|
|
|
|
+ make
