Server1 master

Server2

Server3

Server4

First, server1 downloads the software package:

Libpcap-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm dependent environment

Libpcap-devel-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm dependent environment

Moosefs-3.0.80-1.tar.gz

Yum install-y rpm-build rpm package detection compiler environment installation

Rpmbuild-tb moosefs-3.0.80-1.tar.gz view the compiled package

You may want to install the gcc compilation environment

Yum install gcc-y

Make soft connection ln-s moosefs-3.0.80-1.tar.gz moosefs-3.0.80.tar.gz

Enter the directory cd / root/rpmbuild/RPMS/x86_64

Send client packages to server2 and server3

[root@server1 x86 / 64] scp moosefs-client-3.0.80-1.x86_64.rpm root@172.25.35.250:/root/desktop sends the client software to the tester (here the physical machine will be used for testing later)

Server2,3 installs software, pay attention to parsing, same as server1

[root@server2 ~] # cd / etc/mfs/

[root@server2 mfs] # vim mfshdd.cfg

Append storage path to / mnt/chunk1 document

[root@server2 mfs] # mkdir / mnt/chunk1/

[root@server2 mfs] # mfschunkserver starts, server3 is the same as server2, as long as the file directory is changed to / mnt/chunk2 and server2 is different

Add a hard drive to server2: install scsi service

[root@server2 mfs] # yum install-y scsi- installs all packages of scsi

To achieve high availability, master parsing is the same as server1 installed on server4
