thanks,
I read them, but
for example, what is mean :
Add /usr/local/BerkeleyDB.4.8/ to ld.so.conf ?

knudfl · 12-14-2014, 07:29 AM

← #5 .

"Add /usr/local/BerkeleyDB.4.8/ to ld.so.conf"
means ``Add /usr/local/BerkeleyDB.4.8/ to /etc/ld.so.conf´´

But installing an alien version of db4 to /usr/local isn't recommended.
Please install libdb4.8 / libdb4, for your OS :
Fedora, CentOS : # yum install libdb4
Debian based OS : # apt-get install libdb4.8

Only if you are looking for trouble.
! Install db4.8 from the repositories for your OS.
See post #6.

Which "Linux OS" are you using ? ?
http://www.linuxquestions.org/linux/...Ask_a_Question
http://linuxsilo.net/docs/smart-questions_en.html
I.e. you are supposed to specify your OS every time you ask a question.
→ OS name and version, please.

I'm sorry, you say right,

my linux is centos 6.6 ,
I installed db6.1 that is newer,
in documents that i searched ,write :
"add /usr/local/BerkeleyDB.4.8 to /etc/ld.so.conf "

what is means?

ld.so.conf is a txt file and editable , i must open it and copy text of "/usr/local/BerkeleyDB.6.1" and add end of file and saved?

hamsaeed · 12-15-2014, 08:10 AM

thanks dears,
I installed lessfs as follows:

Quote:

1 Install dependencies:

You may need 'gcc' packages or others to compile.

yum install mhash-devel pkgconfig zlib-devel bzip2-devel

Quote:

2 Install Fuse from source

wget http://sourceforge.net/projects/fuse...ar.gz/download
tar xzvf fuse-2.8.5.tar.gz
cd fuse-2.8.5
./configure && make && make install
cd ..

Quote:

3 Install TokyoCabinet from source

wget http://fallabs.com/tokyocabinet/toky...-1.4.47.tar.gz
tar xzvf tokyocabinet-1.4.47.tar.gz
cd tokyocabinet-1.4.47
./configure && make && make install
cd ..

Quote:

4 Install LessFS from source

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
wget http://sourceforge.net/projects/less...ar.gz/download
tar xzvf lessfs-1.5.4.tar.gz
cd lessfs-1.5.4
./configure && make && make install

Quote:

5 Configure lessfs

cp etc/lessfs.cfg /etc/

Quote:

5.1 Edit /etc/lessfs.cfg

Because the kernel is less than version 2.6.26, it doesn't support block sizes over 4096.

Change the following variable to look like this:

BLKSIZE=4096

Quote:

5.2 Prepare the volume

By default the DB is configured in the /data directory. The following commands will create the database and file structure in /data, and then create the mountpoint used to work with the files.

mklessfs -fc /etc/lessfs.cfg
mkdir /lessfs

Quote:

5.3 Edit /etc/rc.d/rc.local

Add the following line:

modprobe fuse > /dev/null 2>&1

Quote:

5.4 Load the fuse module

modprobe fuse

Quote:

5.5 Configure lessfs startup

You should still be in the lessfs source directory

cp etc/lessfs-init.example /etc/init.d/lessfs

Quote:

5.5.1 Edit /etc/init.d/lessfs

PATH=$PATH:/usr/bin:/usr/local/bin
LD_LIBRARY_PATH=/usr/local/lib
MKLESSFS=/usr/local/bin/mklessfs
MOUNTPOINT=/lessfs
LESSFS_OPTS="/etc/lessfs.cfg $MOUNTPOINT"
LESSFS=/usr/local/bin/lessfs

5.5.2 Add lessfs to init

chkconfig --add lessfs
chkconfig lessfs on

Quote:

6 Start it up and Test it

You can reboot, to test your startup script, or use this command

/etc/init.d/lessfs start

Quote:

6.1 Verify that it's mounted

Running

mount

now , I dont know how cheek that is it work right?

knudfl · 12-15-2014, 09:10 AM

Seems you are using the ancient instructions for CentOS 5 ?
http://www.howtoforge.com/lessfs-1.5-on-centos-5
6 Start it up and Test it.
# /etc/init.d/lessfs start

By the way, your kernel isn't less than 2.6.26 .
CentOS 6.6 has kernel-2.6.32 .
And fuse is included : # yum install fuse-devel
