How to make Linux partition and configure the network on Redhat Linux7.3 ?
Server Information :
master :192.168.2.2
slave_1 :192.168.2.3
slave_2 :192.168.2.4
default gateway :192.168.2.1
OS :Red Hat Enterprise Linux Server release 7.3 Beta (Maipo)
Adding extra slave:192.168.2.5 (without down time)
MASTER PARTITION:
On Master:
For Example:
From master:
ping 192.168.2.3
From slave_1:
ping 192.168.2.4
2.Disk Parition for data/archive/backup:
a)100GB data,50GB archive,40GB backup
For out of range error use "extended" option
B)add the mount point:
As root user:
1. create a mount point for the data partition:
sudo mkdir /DATA
2.This command will format the partition with ext4 FS
mkfs.ext4 /dev/sdc1
3.Mount the partition:
sudo mount /dev/sdb1 /DATA
sudo mount /dev/sdc1 /ARCHIVE
sudo mount /dev/sdd1 /BACKUP
(OR)
mount -t auto /dev/sdc1 /DATA
4.Take ownership of the mount point:
sudo chown -R postgres: /DATA
sudo chown -R postgres: /ARCHIVE
sudo chown -R postgres: /BACKUP
5.Find out the UUID# for your data partition:
gksu gedit /etc/fstab (OR) vi /etc/fstab
(Note: you may need to substitute a different text editor if gedit not installed to your version of Mint.)
In gedit, add either of the two examples below (substitute your UUID# for the ones listed here):
A.For an Ext4 formatted partition, add these two lines to end of fstab file:
master :192.168.2.2
slave_1 :192.168.2.3
slave_2 :192.168.2.4
default gateway :192.168.2.1
OS :Red Hat Enterprise Linux Server release 7.3 Beta (Maipo)
Adding extra slave:192.168.2.5 (without down time)
MASTER PARTITION:
- /mnt/DATA
- /mnt/archive
- /mnt/backup
- /DATA
- /ARCHIVE
- /BACKUP
On Master:
[postgres@master ~]$ cat /etc/redhat-release

#systemctl restart network
(OR)
#service network restart
FOR SLAVE_1 SERVER:--Netcard Entry
cd /etc/sysconfig/network-scripts/
vi ifcfg-ens33
BOOTPROTO=static

## Configure DNS Server
# vi /etc/resolv.conf
nameserver 8.8.8.8 # Replace with your nameserver ip
nameserver 192.168.2.1 # Replace with your nameserver ip
--Host Entry
vi /etc/hosts
192.168.2.3 slave1
--Restart the network services
#systemctl restart network
(Or)
#service network restart
FOR SLAVE_2 SERVER:--Netcard Entry
cd /etc/sysconfig/network-scripts/
vi ifcfg-ens33
BOOTPROTO=static
IPADDR=192.168.2.4

ONBOOT=yes
vi /etc/sysconfig/network

HOSTNAME=slave2
GATEWAY=192.168.2.1
## Configure DNS Server
# vi /etc/resolv.conf

nameserver 192.168.2.1 # Replace with your nameserver ip
--Host Entry
vi /etc/hosts
192.168.2.4 slave2
--Restart the network services
#systemctl restart network
(Or)
#service network restart
Now ping the server slave_1 from master and slave_1 to slave_2 if all successfull then we can go make partition ,if not successfully reaching the other server we can check it the fairwall status and stop it all serverFor Example:
From master:
ping 192.168.2.3
From slave_1:
ping 192.168.2.4

.:. restart the server using init 6,init 0 for shutdownB)add the mount point:
As root user:
1. create a mount point for the data partition:
sudo mkdir /DATA
2.This command will format the partition with ext4 FS
mkfs.ext4 /dev/sdc1
3.Mount the partition:
sudo mount /dev/sdb1 /DATA
sudo mount /dev/sdc1 /ARCHIVE
sudo mount /dev/sdd1 /BACKUP
(OR)
mount -t auto /dev/sdc1 /DATA
4.Take ownership of the mount point:
sudo chown -R postgres: /DATA
sudo chown -R postgres: /ARCHIVE
sudo chown -R postgres: /BACKUP
5.Find out the UUID# for your data partition:
[root@localhost ~]# sudo blkid /dev/sda1: UUID="15fe408e-72ef-47fe-b3f0-e33f032c1d9f" TYPE="xfs" /dev/sda2: UUID="03a8e0e8-ae89-4a1f-bafc-c03826de7ea5" TYPE="swap" /dev/sda3: UUID="f45ae60c-162f-4da2-aa33-f76723e0c5fe" TYPE="xfs" /dev/sdb1: UUID="46c3be28-2646-495e-9d1b-5f9be9d1e154" TYPE="ext4" /dev/sdc1: UUID="c5abf63e-a9ad-410c-a685-4407d9a12b93" TYPE="ext4" /dev/sdd1: UUID="961e84b2-dbe2-4f2c-ade7-72c2b2b5289d" TYPE="ext4" /dev/sr0: UUID="2016-08-17-06-07-50-00" LABEL="RHEL-7.3 Server.x86_64" TYPE="iso9660" PTTYPE="dos"6.Open your fstab file and make an entry to auto-mount the data partition on boot:
gksu gedit /etc/fstab (OR) vi /etc/fstab
(Note: you may need to substitute a different text editor if gedit not installed to your version of Mint.)
In gedit, add either of the two examples below (substitute your UUID# for the ones listed here):
A.For an Ext4 formatted partition, add these two lines to end of fstab file:
# Mount DATA partition under /DATA UUID=46c3be28-2646-495e-9d1b-5f9be9d1e154 /DATA ext4 defaults 0 2 UUID=c5abf63e-a9ad-410c-a685-4407d9a12b93 /ARCHIVE ext4 defaults 0 2 UUID=961e84b2-dbe2-4f2c-ade7-72c2b2b5289d /BACKUP ext4 defaults 0 2B.For an NTFS formatted partition, add these two lines to end of fstab file:
# Mount DATA partition under /DATA UUID=747D4C9C1EFAD1F2 /DATA ntfs-3g defaults,windows_names,locale=en_US.utf8 0 0Save the changes to fstab and close the text editor or vim editor
