下载安装snappy库
If you didn't install snappy under /usr or /usr/local, you need to specify the location by --with-snappy as follows.
# download snappy http://pkgs.fedoraproject.org/repo/pkgs/snappy/ # install snappy tar xvfz snappy-1.1.3.tar.gz cd snappy-1.1.3 ./configure --prefix=/usr/local/snappy make make install
Step2 : 下载安装snzip命令
# download snzip https://bintray.com/kubo/generic/snzip, # install snzip tar xvfz snzip-1.0.4.tar.gz cd snzip-1.0.4 ./configure --with-snappy=/usr/local/snappy make make install
You can use --with-default-format to change the default compression format.
./configure --with-default-format=snzip
