Distributed File System Moosefs installation steps

1. Installation 1.1 Prepare the installation environment

First choose a better server to do master, if you can choose a backup server as Master best. Then the other servers become chunkserver.

For the sake of explaining the problem, I choose here:

Master server 1 Units 192.168.2.98

Chunkserver server 2 units 192.168.2.222 and 192.168.2.223

Client server 1 Units 192.168.2.55

1.2 Installation Steps

(1). fuse-2.8.5.tar.gz

(2). mfs-1.6.20-2.tar.gz

Although Fuse is used only by the client, we install the fuse module on all computers for uniform installation steps.

Put both fuse-2.8.5.tar.gz and mfs-1.6.20-2.tar.gz in the/OPT directory.

1.2.1 Create User:

[Email protected]]# groupadd MFS

[[Email protected]]# useradd-g MFS MFS

Because the default running user for Moosefs is MFS, it is created first.

1.2.2 Installing fuse:

[[Email protected]]# ls/opt/

Fuse-2.8.3.tar.gz mfs-1.6.20-2.tar.gz

[Email protected]]# tar-zxvf fuse-2.8.3.tar.gz

[[Email protected]]# CD fuse-2.8.3

[Email protected]]#./configure

[Email protected]]#./make

[Email protected]]#./make Install

[Email protected]]# CD.

Follow the steps above to install fuse.

1.2.3 Installing Moosefs:

[[Email protected]]# ls/opt

fuse-2.8.3 fuse-2.8.3.tar.gz mfs-1.6.20-2.tar.gz

[Email protected]]# tar-zxvf mfs-1.6.20-2.tar.gz

[[Email protected]]# CD mfs-1.6.20-2

[Email protected] mfs-1.6.20-2]#./configure--prefix=/usr/local/mfs--with-default-user=mfs--with-default-group= Mfs

[[email protected] mfs-1.6.20-2]# make

[[email protected] mfs-1.6.20-2]# make install

2. Configuration Instructions

First put all the configuration files into the/etc/mfs directory

[Email protected]]# mkdir-p/etc/mfs

[[Email protected]]# cd/opt/mfs-1.6.20-2

[Email protected]]# CP./mfsdata/mfshdd.cfg/etc/mfs/

[Email protected]]# CP./mfsdata/mfsexports.cfg/etc/mfs/

[Email protected]]# CP./mfsdata/mfschunkserver.cfg/etc/mfs/

[Email protected]]# CP./mfsdata/mfsmaster.cfg/etc/mfs

[Email protected]]# CP./mfsdata/mfsmetalogger.cfg/etc/mfs

[Email protected]s]# mkdir-p/data/mfs

[Email protected]]# chmod-r 777/data/mfs

Down to edit the configuration file:

[Email protected] mfs]# VI mfsmaster.cfg

[Email protected] mfs]# VI mfschunkserver.cfg

2.1 Starting the master server

[Email protected] mfs]# Cp/usr/local/mfs/var/mfs/metadata.mfs.empty/data/mfs/metadata.mfs

[[Email protected]]#/usr/local/mfs/sbin/mfsmaster-c/etc/mfs/mfsmaster.cfg Start

[Email protected]]# ps-aux|grep Mfsmaster

2.2 Starting the backup server for master

[Email protected] mfs]#/usr/local/mfs/sbin/mfsmetalogger-c/etc/mfs/mfsmetalogger.cfg start

Working Directory:/data/mfs

Lockfile Createdand Locked

Mfsmetaloggerdaemon initialized properly

2.3 Starting the Chunkserver server

The Chunkserver server needs to use the Mfshdd.cfg configuration file, which is designed to allow the server to manage multiple hard disks while placing data on them.

[Email protected]]# VI mfshdd.cfg

# mount points OFHDD drives

#

/mnt/hd1

/mnt/hd2

#etc.

Once you have edited the above configuration file, you can start chunkserver with the following command.

[[email protected] mfs]#/usr/local/mfs/sbin/mfschunkserver-c/etc/mfs/mfschunkserver.cfg start

Moosefs also brings a web monitoring tool that you need to start Mfscgiserv

The start command is as follows:

[Email protected] mfs]#/usr/local/mfs/sbin/mfscgiserv

You can then enter the following address in your browser to see how your data is saved.

http://192.168.2.55:9425/mfs.cgi

2.4 Mounting the Client

[Email protected] mfs]# mkdir-p/mnt/mfs

[Email protected] mfs]# chmod-r 777/mnt/mfs

[Email protected] mfs]#/usr/local/mfs/bin/mfsmount/mnt/mfs/-H 192.168.2.85

[Email protected] mfs]# df–h

If the command can see

mfs#192.168.2.85:9421 such a line, on behalf of the success of the mount, down can be used, the official installation is complete.
