Centos7 important changes
Centos7 compared to the previous Centos some changes related to commonly used commands, if you do not know in advance, can cause great distress at the time of using the command
Centos7 no default ifconfig and netstat two commands, ip addr command instead of ifconfig, just install the net-tools package you can continue to use the two commands ifconfig and netstat
Appears systemctl command (systemctl can be seen as a combination of service and chkconfig), although you can still use the previous command, but will be redirected to the new command, the following services, for example with http
job
Previous system
CentOS7
Service boot
chkconfig --level 3 httpd on
systemctl enable httpd.service
Service does not boot
chkconfig --level 3 httpd off
systemctl disable httpd
Service Status
service httpd status
systemctl status httpd
Start the status of all services
chkconfig --list
systemctl
Start Service
service httpd start
systemctl start httpd.service
Out of service
service httpd stop
systemctl stop httpd.service
Restart Service
service httpd restart
systemctl restart httpd.service
Configuring the development environment
Synchronization Time
The monitoring system once all the machines are synchronized network time (very important)
[Root @ localhost ~] timedatectl # This command is used to check the current time and time zone
If you find the time zone for all machines are inconsistent, then you must use the command
[Root @ localhost ~] timedatectl list-timezones # This command lists all time zones
[Root @ localhost ~] timedatectl set-timezone Asia / Shanghai # This command sets the time zone is set to Shanghai
ntpdate time.nist.gov # The current command to synchronize network time
If no ntpdate command prompt, install ntp, and configure the system to automatically update the time
[Root @ localhost ~] # yum install ntp -y
[Root @ localhost ~] # / usr / sbin / ntpdate time.nist.gov
[Root @ localhost ~] # echo '#time sync' >> / var / spool / cron / root
[Root @ localhost ~] # echo '* / 10 **** / usr / sbin / ntpdate time.nist.gov> / dev / null 2> & 1' >> / var / spool / cron / root
Close Selinux
Do not turn off selinux may cause some subtle error, to be safe, first turn off selinux:
[Root @ localhost ~] vi / etc / selinux / config
Restart the machine
Check selinux is closed:
[Root @ localhost ~] getenforce # If there is no enforcing Close
Packages uploaded using SecureCRT
SSH connectivity tools I use here is SecureCRT7.2, step through this tool to upload files to Linux as follows:
1. First Install file transfer command in Linux:
[Root @ localhost ~] yum install lrzsz -y
2. Then jump to the next / usr / local / src directory in Linux
[Root @ localhost ~] cd / usr / local / src
3. Run the file transfer commands CRT
Install Mail Service
Because e-mail alert service to install mail function
[Root @ localhost ~] yum install -y mailx
[Root @ localhost ~] yum install -y sendmail
[Root @ localhost ~] systemctl restart sendmail.service
[Root @ localhost ~] mail -s Test xxx@xxx.com (your email address)

Commonly used commands
Contents of the command
Command Format
Check whether the nagios configuration file is wrong
/etc/init.d/nagios checkconfig
or
/ Usr / local / nagios / bin / nagios -v /usr/local/nagios/etc/nagios.cfg
Start nagios
systemctl start nagios.service
or
/ Usr / local / nagios / bin / nagios -d /usr/local/nagios/etc/nagios.cfg
Reload the profile to modify the nagios configuration files
/ Etc / init
Nagios install the required operating environment
[Root @ localhost ~] # yum install gcc glibc glibc-common -y
[Root @ localhost ~] # yum install php php-gd perl -y
[Root @ localhost ~] # yum install httpd gd gd-devel openssl openssl-devel -y
[Root @ localhost ~] # systemctl enable httpd.service # set CentOS boot service
Increase user
[Root @ localhost ~] useradd -m nagios
And nagios and apache user to the group nagcmd
[Root @ localhost ~] groupadd nagcmd
[Root @ localhost ~] usermod -G nagcmd nagios
[Root @ localhost ~] usermod -a -G nagcmd apache # users to add apace with a group of nagios (apache user will be created automatically when you install apache)
Install nagios
[Root @ localhost src] # tar -zxvf nagios-4.0.8.tar.gz
[Root @ localhost src] # cd nagios-4.0.8
Initializes the environment and the establishment of a compiled
[Root @ localhost nagios-4.0.8] #. / Configure --with-command-group = nagcmd
If you can see the following description of the basic configuration information environment has successfully completed the initial configuration:
Follow the prompts after the command to compile:
[Root @ localhost nagios-4.0.8] # make all
[Root @ localhost nagios-4.0.8] # make install
[Root @ localhost nagios-4.0.8] # make install-init
[Root @ localhost nagios-4.0.8] # make install-config
[Root @ localhost nagios-4.0.8] # make install-commandmode
[Root @ localhost nagios-4.0.8] # make install-webconf
After installation is complete, in the / usr / local / nagios directory to see if these directories:
Naigos says the installation was successful.
Nagios sample configuration file is installed by default in / usr / local / nagios / etc directory, you can configure these files required to run such nagios (detailed configuration procedure, please refer to my other blog post: nagios service configuration in detail)
At this time should be to specify that you want to receive email warning nagios mail address information, the default is nagios user's local machine:
[Root @ localhost] # vi /usr/local/nagios/etc/objects/contacts.cfg
email nagios @ localhost # place to Miaohong modify your email address
Create a login nagios web application user (you do not need to configure the user name configured nagiosadmin permission settings will configure permissions for other users name), I am here to set the user name kylinlin, password is 123456, the user account in the future through the web authentication login nagios used:
[Root @ localhost ~] # htpasswd -bc /usr/local/nagios/etc/htpasswd.users kylinlin 123456 # place to Miaohong modify your username and password
Configuring Permissions
If you created above landing nagios web application's user name is not nagiosadmin (I mentioned above has been set to kylinlin), after landing nagios web interface (in this case we can not log on, but if you ignore this section of the configuration, landing in the back will see the following interface), click Hosts or Services displayed picture red error
Because nagios default permissions to the entire nagiosadmin, it can give permission to modify cgi.cfg kylinlin file, switch to the / usr / local / nagios / etc directory
[Root @ localhost etc] # sed -i 's # nagiosadmin # kylinlin # g' cgi.cfg # This command will nagiosadmin username replaced kylinlin
[Root @ localhost etc] # grep kylinlin cgi.cfg # This command to check whether the amendment is successful
After configuring the above process ends need to restart httpd:
[Root @ localhost etc] # systemctl restart httpd.service
Check the main configuration file syntax is correct:
[Root @ localhost etc] # / usr / local / nagios / bin / nagios -v /usr/local/nagios/etc/nagios.cfg
Or use the following command to check the syntax
[Root @ localhost etc] # /etc/init.d/nagios checkconfig
The error number is correct only 0
Configuration is successful
Install plug
Have already mentioned Nagios is a main control center, which can play a monitoring service and system monitoring functions are numerous Nagios plug-ins, no plug-ins Nagios system is actually just a shell. Therefore, after installing the Nagios platform we also need to install plug-ins.
Nagios plug-in is also on its official website, the current version is 1.4.15. I will download the source package into / usr / local directory, follow these steps to unpack, compile and install:
[Root @ localhost src] # tar zxf nagios-plugins-2.0.3.tar.gz
[Root @ localhost src] # cd nagios-plugins-2.0.3
[Root @ localhost nagios-plugins-2.0.3] # ./configure --with-nagios-user = nagios --with-nagios-group = nagios
[Root @ localhost nagios-plugins-2.0.3] #make
[Root @ localhost nagios-plugins-2.0.3] #make install
By the following command to view the number of installed plug-ins
[Root @ localhost nagios-plugins-2.0.3] #ls / usr / local / nagios / libexec / | wc -l
Nagios is then added to the list of services to enable it to start automatically at system startup:
[Root @ localhost nagios-plugins-2.0.3] # chkconfig --add nagios
[Root @ localhost nagios-plugins-2.0.3] # chkconfig nagios on
Run the following command to verify Nagios sample configuration file:
[Root @ localhost ~] # / usr / local / nagios / bin / nagios -v /usr/local/nagios/etc/nagios.cfg
Open http ports in the firewall
firewall-cmd --add-service = http (instant open)
firewall-cmd --permanent --add-service = http (the configuration file)
firewall-cmd --reload (reboot the firewall)
Start nagios service
[Root @ localhost ~] # / usr / local / nagios / bin / nagios -d /usr/local/nagios/etc/nagios.cfg
After the browser can access links http://192.168.1.204/nagios, enter the login name and password, if you can see the page properly, proved the main program and plug-ins are installed and configured successfully! Click on "Service" link to view the details of your surveillance of the machine. At this point you may need to give some time for Nagios to detect your machine depend on the service.
WARNING in a state of service, so I had to configure mailbox has received an alarm message, if you do not receive a warning message, this time to check whether you have configured the mailbox to receive alarm information, and check whether as spam blocked.
Installation nrpe
[Root @ localhost src] # tar -zxf nrpe-2.15.tar.gz
[Root @ localhost src] # cd nrpe-2.15
[Root @ localhost nrpe-2.15] # ./configure --with-nrpe-user = nagios \
--with-nrpe-group = nagios \

[Root @ localhost nrpe-2.15] # make all
[Root @ localhost nrpe-2.15] # make install-plugin
[Root @ localhost nrpe-2.15] # make install-daemon
[Root @ localhost nrpe-2.15] # make install-daemon-config
Check / usr / local / nagios / libexec directory if you have installed the plug-check_nrpe
[Root @ localhost libexec] # ls | grep check_nrpe

Commonly used commands
Contents of the command
Command Format
Close nrpe
pkill nrpe
Start nrpe
/ Usr / local / nagios / bin / nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
Start nrpe (applies only to write the script nrpe case)
systemctl start nrpe.service
Check whether to activate nrpe
netstat -lnt
(5666 by checking whether the port is open)
Configuring Operating Environment
First, turn off the firewall:
[Root @ localhost ~] # systemctl stop firewalld.service
[Root @ localhost ~] # yum install gcc glibc glibc-common -y
[Root @ localhost ~] # yum install gd gd-devel openssl openssl-devel -y
[Root @ localhost ~] # yum install php php-gd perl net-tools -y
Install nagios-plugin
1) first add nagios user
[Root @ localhost ~] # useradd -s / sbin / nologin nagios # ban nagios user login
2) NRPE dependent on nagios-plugins, therefore, need to install the
Go to the next / usr / local / src directory began to execute the following command
[Root @ localhost src] # tar zxf nagios-plugins-2.0.3.tar.gz
[Root @ localhost src] # cd nagios-plugins-2.0.3
[Root @ localhost nagios-plugins-2.0.3] # ./configure --with-nagios-user = nagios --with-nagios-group = nagios
[Root @ localhost nagios-plugins-2.0.3] # make all
[Root @ localhost nagios-plugins-2.0.3] # make install
Installation nrpe
Go to the next / usr / local / src directory began to execute the following command
[Root @ localhost src] # tar -zxf nrpe-2.15.tar.gz
[Root @ localhost src] # cd nrpe-2.15
[Root @ localhost nrpe-2.15] # ./configure --with-nrpe-user = nagios \

[Root @ localhost nrpe-2.15] # make all
[Root @ localhost nrpe-2.15] # make install-plugin
[Root @ localhost nrpe-2.15] # make install-daemon
[Root @ localhost nrpe-2.15] # make install-daemon-config
[Root @ localhost nrpe-2.15] # ls / usr / local / nagios / libexec / # If the installation is successful there are a lot NRPE plugin
Pay attention to whether check_nrpe this plug (no words to explain the nrpe not installed successfully)
Start nrpe
Method One: The command to start nrpe
[Root @ localhost ~] # / usr / local / nagios / bin / nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
# This command starts nrpe
If you want to restart nrpe, first execute the command:
[Root @ localhost ~] # pkill nrpe # Close nrpe
[Root @ localhost ~] # netstat -lnt # This command is used to check the port to see if the port has been closed 5666
[Root @ localhost ~] # / usr / local / nagios / bin / nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
# Restart process nrpe
Method Two: Create a startup script nrpe
For the startup NRPE service can be defined as the following /etc/init.d/nrpe script in the /etc/init.d directory nrpe file a new name, copy the contents into the following
#! / Bin / bash
# Chkconfig: 2345 88 12
# Description: NRPE DAEMON
NRPE = / usr / local / nagios / bin / nrpe
NRPECONF = / usr / local / nagios / etc / nrpe.cfg
case "$ 1" in
start)
echo -n "Starting NRPE daemon ..."
$ NRPE -c $ NRPECONF -d
echo "done."
;;
stop)
echo -n "Stopping NRPE daemon ..."
pkill -u nagios nrpe
echo "done."
;;
restart)
$ 0 stop
sleep 2
$ 0 start
;;
*)
echo "Usage: $ 0 start | stop | restart"
;;
esac
exit 0
Then add permission to run:
[Root @ localhost ~] # chmod + x /etc/init.d/nrpe
Start nrpe
[Root @ localhost ~] # systemctl start nrpe.service
Check that port 5666 started successfully
[Root @ localhost ~] # netstat -tnlp
5666 port has been successfully started
Add /usr/local/nagios/etc/nrpe.cfg file monitoring host ip address
[Root @ localhost etc] # vi nrpe.cfg +81
The allowed_hosts = 127.0.0.1 modify allowed_hosts = 127.0.0.1,192.168.1.204 (which is monitoring host ip address of the machine ip address is 192.168.1.112)
Then restart nrpe
[Root @ localhost ~] # pkill nrpe
[Root @ localhost ~] # / usr / local / nagios / bin / nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
On the monitoring host (ip address 192.168.1.204) Enter the following command to check for successful communication between two machines
[Root @ localhost ~] # cd / usr / local / nagios / libexec /
[Root @ localhost libexec] # ./check_nrpe -H 192.168.1.113
NRPE v2.15 # successful communication
At this point, the remote host to install nagios completed.

Possible that the firewall blocked port 80, then open the firewall to port 80:
firewall-cmd --add-service = http (instant open)
firewall-cmd --permanent --add-service = http (the configuration file)
firewall-cmd --reload (reboot the firewall)
If the following error appears:
You do not have permission to access / nagios / on this server.nagios
At this point you want to install php
yum install php -y
Then restart httpd:

But can not communicate with each other after the start nrpe
First start nrpe process
systemctl restart nrped.service
At this point you can check nrpe binding 5666 port is blocked by the firewall:
netstat -tnpl (observe whether there are one of two services below)
If port 5666 is not open on the firewall to open port 5666:
firewall-cmd --zone = public --add-port = 5666 / tcp --permanent (add 5666 port)
firewall-cmd --reload (reboot the firewall)
Or directly off the firewall

The requested URL / pnp4nagios / graph was not found on this server after installation pnp4nagios.
Reason, when you perform the installation in pnp4nagios make install-webconf, note that it generated a apache configuration file.
You put this file: /etc/httpd/conf.d/pnp4nagios.conf All contents all added to the apache httpd.conf file Finally, restart nagios and apache should be friends.
