Make your lan connections eth0,eth1 from ens33 etc in CentOS 7

yum -y install ftp nano net-tools #(net-tools for ifconfig)

go to /etc/hostname

server1.sourav.com

go to /etc/hosts

the file is like this

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6


make it look like

127.0.0.1  server1.sourav.com localhost localhost.localdomain localhost4 localhost4.localdomain4
::1       server1.sourav.com  localhost localhost.localdomain localhost6 localhost6.localdomain6


now ifconfig command shows the interface as ens33,I want to make the two lan adapter as eth0 and eth1

nano /etc/default/grub

find this line

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto  vconsole.keymap=us rhgb quiet"

and make it look like that

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto  vconsole.keymap=us rhgb quiet net.ifnames=0 biosdevname=0"

save and exit

reboot


ifconfig eth0 down

ifconfig eth1 down

and

ifconfig eth0 up

will do the managing for you


run this command

grub2-mkconfig -o /boot/grub2/grub.cfg

reboot

run ifconfig

you will see the network adapters as eth0 and eth1

cd /etc/sysconfig/network-scripts/

mv ifcfg-ens33 ifcfg-eth0

nano ifcfg-eth1

DEVICE="eth1"

NAME="eth1"

IPADDR=10.10.0.1

delete the gate way and dns

delete the uuid

get the proper mac address for ethernet adapter2

BOOTPROTO="static"

ONBOOT="yes"

Del PEERROUTES,PEERDNS,DEFROUTE portions on eth1

save and exit


systemctl stop NetworkManager

systemctl disable NetworkManager

systemctl restart network

now you are fine

Install and configure Xymon to monitor Slackware part 1

download rrdtool and fping and xymon package in tar.gz format

tar -zxvf fping ...

cd fping ..

./configure

make

make install


tar -zxvf rrdtool...

cd rrdtool

./configure

make

make install

tar -zxvf xymon-...

cd xymon ..

groupadd xymon

useradd xymon -g xymon

./configure.server

keep saying y to the questions(press enter)

when asked which group does the webserver use

the answer should be apache

the ip address of the machine should not be 127.0.0.1

it should be

192.168.28.51

and keep saying yes and you are done


make

make install

type

visudo

or

mcedit /etc/sudoers

under the section

Cmnd alias specification

Write Cmnd_Alias and press tab

Cmnd_Alias    XYM = /usr/local/sbin/fping *

then go to user privilege specification

go to under the line as

root    All=(ALL)  All

type

xymon    All = NOPASSWD: XYM


save and exit

su xymon

and try to run

/usr/local/sbin/fping google.com

and I have faced this error

Fping can only be run by root

So I tried

as root

chown root:xymon /usr/local/sbin/fping

chmod 710 /usr/local/sbin/fping

chmod ug+s /usr/local/sbin/fping

and then

become xymon

su xymon

and then

/usr/local/sbin/fping google.com

the thing is working now

become root

mc

go to /home/xymon/server/etc

see if hobbitserver.cfg exists

go to /etc/httpd/httpd.conf

Under the line

Include /etc/httpd/mod_php.conf

Write

Include /home/xymon/server/etc/hobbit-apache.conf

save and exit

/etc/rc.d/rc.httpd restart

su xymon

/home/xymon/server.hobbit.sh start

ps aux | grep hobbit


Now from a client pc

if I type

http://192.168.28.51/xymon

it shows 404 Not Found URL/xymon was not found on this server

So I went to

cd /home/xymon/server/etc

nano hobbit-apache.conf

find this line

Alias /xymon/  "/home/xymon/server/www/"

and change it to

Alias /xymon  "/home/xymon/server/www"

save and exit

/etc/rc.d/rc.httpd restart

and

open from client pc

192.168.28.51/xymon

it is working now

go to

cd /home/xymon/server/etc

nano bb-hosts

add this line at the last

10.10.29.141    MyPC             #Win8


save and exit

su xymon

/home/xymon/server/hobbit.sh stop

/home/xymon/server/hobbit.sh start

now you will find 2 host on the main view of xymon

at 192.168.28.51/xymon
