Splunk Standalone node
installations
Environment Setup
·
Download Ubuntu Linux 12.04.3 LTS or CentOS 6.7 (Any linux flavor)
·
Download Latest Splunk Enterprise tar ball ( For simplicity)
Pre-requisites
·
Do the necessary network
settings and assign static IP if preferred.
·
Assign the hostname in network
and hosts files.
·
All hosts must be recent
version of Linux x86_64 (kernel +2.6)
- Python 2.7 must installed and present in
PATH. Python 3 is NOT supported.
- Additionally, the following Python
modules must be installed:
- pycrypto (needed by paramiko)
- simplejson
- pyyaml
* These modules can usually be
installed using 'pip'
- sar must be installed on all systems.
- needed for metrics
- All hosts must be reachable from each
other.
- DNS must be working or,
alternatively, host files must be working
- All hosts must be running SSH.
- Preferably, SSH keys should be
exchanged to all
- Time is synchronized on all hosts.
- This is *extremely* important as many
measurements depend on time
accuracy.
Install python 2.7
Redhat now has "Software Collections" which take care
of this sort of thing, so you can do:
yum install centos-release-SCL
yum install python27
yum install python27
Then if you want to use if in your
shell you would run something like:
scl enable python27 bash
Which sets up the correct
environment variables (including PATH and LD_LIBRARY_PATH etc) and dumps you
into a new shell - pretty sure it would't be too hard to make that the
default.....
Install pycrypto
yum install
gmp-devel
pip install
pycrypto
Install SimpleJson.
Install Pyyaml
Install sar
yum install
syssstat
