snappy 在linux安装及使用


If you didn't install snappy under /usr or /usr/local, you need to specify the location by --with-snappy as follows.

# download snappy

# install snappy
tar xvfz snappy-1.1.3.tar.gz
cd snappy-1.1.3
./configure --prefix=/usr/local/snappy
make install


Step2 : 下载安装snzip命令

# download snzip

# install snzip
tar xvfz snzip-1.0.4.tar.gz
cd snzip-1.0.4
./configure --with-snappy=/usr/local/snappy
make install


You can use --with-default-format to change the default compression format.

./configure --with-default-format=snzip


[root@test1 ~]# snzip -h
