Zabbix server side: centos7.6

Turn off the firewall and selinux, set the time zone and time synchronization

~] # systemctl stop firewalld

~] # systemctl disable firewalld

~] # setenforce 0

~] # vim / etc/sysconfig/selinux

SELINUX=disabled # change enforcing to disabled

# timedatectl set-timezone Asia/Shanghai

~] # yum-y install chrony

~] # vim / etc/chrony.conf

Server ntp1.aliyun.com iburst # modified to ntp server of Aliyun

~] # systemctl restart chronyd

Replace the yum source with Ali Cloud Source

~] # mv / etc/yum.repos.d/CentOS-Base.repo / etc/yum.repos.d/CentOS-Base.repo.backup

~] # curl-o / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

~] # curl-o / etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

~] # yum makecache

Third, install the LAMP environment

~] # yum-y install mariadb mariadb-server httpd php php-mysql

~] # systemctl start httpd mariadb

~] # systemctl enable httpd mariadb

~] # mysql_secure_installation

Fourth, install the zabbix program, choose 3.0LTS (long-term maintenance version)

~] # rpm-Uvh https://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

~] # yum clean all

~] # yum-y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

Initialize the database:

~] # mysql-uroot-p

MariaDB [(none)] > create database zabbix character set utf8 collate utf8_bin

MariaDB [(none)] > grant all privileges on zabbix.* to zabbix@localhost identified by 'password'; # where password is the database password of zabbix, set it by yourself

MariaDB [(none)] > quit

~] # zcat / usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql-uzabbix-p zabbix # enter the password of zabbix user

~] # vim / etc/zabbix/zabbix_server.conf

DBPassword=password # enter the password of the zabbix user

~] # vim / etc/httpd/conf.d/zabbix.conf

Php_value date.timezone Asia/Shanghai # enter the correct time zone information

~] # systemctl restart zabbix-server zabbix-agent httpd

~] # systemctl enable zabbix-server zabbix-agent httpd

5. The browser initializes the web of zabbix

~] # vim / etc/httpd/conf/httpd.conf

DocumentRoot "/ usr/share/zabbix"

~] # systemctl restart httpd

To access http://server-ip, the default account is Admin and the password is zabbix. Attention to production environment: 1, modify Admin password; 2, shut down guest users.

Sixth, due to many template support problems in 3.0, so upgrade to 4.0LTS here.

Aliyun's zabbix repository source package:

Https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm

Please refer to the official upgrade guide:

Https://www.zabbix.com/documentation/4.0/zh/manual/installation/upgrade/packages/rhel_centos

7. Add Chinese support to avoid Chinese garbled problems: the difference between 3.0and 4.0path: / usr/share/zabbix/fonts/ 4.0path: / usr/share/zabbix/assets/fonts/

The following example is the 4.0LTS version

Find a windows host: win+R, enter fonts (that is, C:\ Windows\ Fonts), and select a font (here example: Arial routine)

Upload font file to zabbix-server by dragging: premise ~] # yum-y install lrzsz

~] # mv simsun.ttc / usr/share/zabbix/assets/fonts/song.ttf

~] # chmod adepx / usr/share/zabbix/assets/fonts/song.ttf

~] # vim / usr/share/zabbix/include/defines.inc.php

Define ('ZBX_GRAPH_FONT_NAME',' song'); # modify the font graphfont to song

Common monitoring methods:

First, monitor through agent:

1. Install the zabbix-agent program and set the configuration file

Centos 7

~] # rpm-Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-agent-4.0.15-1.el7.x86_64.rpm

~] # vim / etc/zabbix/zabbix_agentd.conf

Server=172.20.120.214 # set server IP

# ServerActive=172.20.120.214 # active mode is not enabled here, so comments (active mode is where the client actively sends data to the server)

Hostname=172.20.120.182 # sets the name of the client

~] # systemctl start zabbix-agent

~] # systemctl enable zabbix-agent

Centos6

~] # sudo rpm-Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/6/x86_64/zabbix-agent-4.0.15-1.el6.x86_64.rpm

~] # hostip= `ip addr l | grep eth0 | grep inet | awk-F "/"'{print $1}'| awk'{print $2}'`# the network card obtained here is eth0. Please modify it as needed.

[] # sudo sed-I-e Universe 127.0.0.1Universe 172.20.120.214 g'-e s/Hostname=Zabbix server/Hostname=$hostip/g / etc/zabbix/zabbix_agentd.conf

~] # sudo service zabbix-agent start

~] # sudo chkconfig zabbix-agent on

2. Add the mode to web monitoring:

A, add manually

Access web http://server-ip: configure-CVM-create CVM-set CVM related information: as shown in figure

B, automatic discovery

Steps:

1. Set the actions to be taken after automatic discovery

Access web http://server-ip: configure-Action-event Source (Auto-Discovery)-create Action

2. Set auto-discovery rules

Access http://server-ip on the web: configure-automatically discover-create discovery rules

Zabbix monitors nginx performance

1. Check whether there is a with-http_stub_status_module for this module.

~] # nginx-V

2. Configure the nginx status page

~] # vim / etc/nginx/nginx.conf

Location / ngx_status {

Stub_status on

Access_log off

Allow 127.0.0.1

}

~] # systemctl reload nginx

Test whether you can get the status page

~] # curl http://127.0.0.1/ngx_status

The fields are explained as follows:

Active connections: indicates the number of active connections being processed by Nginx.

Server: indicates how many connections have been processed by Nginx since its startup

Accepts: indicates how many handshakes have been successfully created since Nginx was launched

Handled requests: indicates the total number of requests processed

Reading: the number of Header messages read by Nginx to the client

Writing: the number of Header messages returned by Nginx to the client

Waiting: Nginx has finished processing the resident link waiting for the next request instruction (when keep-alive is turned on, this value is equal to Active- (Reading+Writing))

Therefore, when the access efficiency is high and the request is processed quickly, it is normal to have a large number of Waiting. If there are a large number of reading + writing, the concurrent traffic is very large and is in the process of being processed.

3. Write a monitoring script

~] # vim / etc/zabbix/ngx_status.sh

#! / bin/bash

HOST= "127.0.0.1"

PORT= "80"

# detect whether the nginx process exists

Function ping {

/ sbin/pidof nginx | wc-l

}

# testing nginx performance

Function active {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | grep 'Active' | awk' {print $NF}'

}

Function reading {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | grep 'Reading' | awk' {print $2}'

}

Function writing {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | grep 'Writing' | awk' {print $4}'

}

Function waiting {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | grep 'Waiting' | awk' {print $6}'

}

Function accepts {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | awk NR==3 | awk'{print $1}'

}

Function handled {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | awk NR==3 | awk'{print $2}'

}

Function requests {

/ usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2 > / dev/null | awk NR==3 | awk'{print $3}'

}

# execute function

, 1

~] # chmod adepx / etc/zabbix/ngx_status.sh

Test script

~] # bash / etc/zabbix/ngx_status.sh requests

4. Zabbix-agent configuration file

~] # vim / etc/zabbix/zabbix_agentd.conf

UnsafeUserParameters=1

UserParameter=nginx.status [*], / etc/zabbix/ngx_status.sh $1

~] # systemctl restart zabbix-agent

~] # systemctl enable zabbix-agent

Zabbix server side test

~] # yum-y install zabbix-get

~] # zabbix_get-s 172.20.120.56-k 'nginx.status [accepts]' #-s followed by agent-ip,-k followed by custom key

5. Zabbix web terminal

Download template: https://pan.baidu.com/s/1CCaIURk-kXAcEXJ6BD-TEA

Import template

Host configuration

Host add template (Template App NGINX)

Second, monitor through snmp:

Zabbix Monitoring Dell Server hardware (iDRAC)

1. Dell server

Log in to iDRAC by browser

Enable SNMP

Click "iDRAC"-- "Network"-- "Service"-- "SNMP Agent"

Check "enabled" and click "apply"

2. Zabbix web terminal

Download template: https://pan.baidu.com/s/1CCaIURk-kXAcEXJ6BD-TEA

Import template

Host configuration SNMP interfaces

Host add template Dell iDRAC; Note: the setting of the macro needs to correspond (that is, the value of SNMP community should correspond).

Zabbix monitors Huawei switches and firewall devices

1. Enable the snmp function in the switch and firewall, and set SNMP community

2. Zabbix web terminal

Download template: https://pan.baidu.com/s/1CCaIURk-kXAcEXJ6BD-TEA

Import template

Host configuration SNMP interfaces

Host add template (Template Net Huawei VRP SNMPv2) Note: the setting of the macro needs to correspond (that is, the value of SNMP community should correspond).

Monitoring of windows server:

1. Install the agent client; download address https://assets.zabbix.com/downloads/4.0.15/zabbix_agents-4.0.15-win-amd64-openssl.zip on the official website

Decompress zabbix_agents-4.0.15-win-amd64-openssl.zip

The conf directory is an agent configuration file

Bin files are stored in windows programs.

Modify the zabbix_agentd.conf file in the conf directory

LogFile=c:\ zabbix_agentd.log / / Log location

EnableRemoteCommands=1 / / allows local execution of remote commands

LogRemoteCommands=1 / / whether the operation log is saved when executing remote commands

Server=172.20.120.214 / / zabbix_server host IP address

# ServerActive=192.168.1.10 / / since active mode is not enabled, you can simply comment

Hostname=* / / monitored hostname, own hostname

Open a command prompt to install

C:\ zabbix\ bin\ zabbix_agentd.exe-I-c c:\ zabbix\ conf\ zabbix_agentd.conf

C:\ zabbix\ bin\ zabbix_agentd.exe-s-c c:\ zabbix\ conf\ zabbix_agentd.conf

After the installation, the zabbix-agent service is available in the service.

Finally, remember to set up a firewall to allow zabbix-agent interconnection

Windows supplement points:

There is no cpu usage monitoring item in the default windows template, which is added as follows:

Name: CPU usage%

Key value: perf_counter [\ Processor (_ Total)\% Processor Time]

Information type: floating point number

Unit:%

Problem: unable to get cpu utilization. Server log: Collector is not started

Solution: rebuild the performance counter settings: the administrator can execute the lodctr / R command

Set the alarm mode:

2. Aliyun SMS alarm: here is an example of using python3.6+ (there is garbled code in Chinese SMS messages in python2)

1. CentOS7 upgrade Python2.x to 3.x

~] # python-V # View the current python version

~] # yum-y install python3

~] # mv / usr/bin/python / usr/bin/python.bak

~] # ln-sv / usr/bin/python3 / usr/bin/python

To be compatible with yum: modify the / usr/bin/yum and / usr/libexec/urlgrabber-ext-down files, change #! / usr/bin/python to #! / usr/bin/python2.7

2. Install Aliyun SDK core library:

~] # pip3 install aliyun-python-sdk-core

3. Aliyun SMS service, apply for SMS signature and template: pass three parameters here: ${host}, ${time}, and ${item}.

4. Write python scripts and test

~] # vim / usr/lib/zabbix/alertscripts/sendsms.py

#! / usr/bin/env python

#-*-coding: utf-8-*-

From aliyunsdkcore.client import AcsClient

From aliyunsdkcore.request import CommonRequest

Import sys

Client = AcsClient ('','', 'default') # fill in the accesskey information here, and the obtained address is https://usercenter.console.aliyun.com

Request = CommonRequest ()

Request.set_accept_format ('json')

Request.set_domain ('dysmsapi.aliyuncs.com')

Request.set_method ('POST')

Request.set_protocol_type ('https') # https | http

Request.set_version ('2017-05-25')

Request.set_action_name ('SendSms')

# the first parameter passed by zabbix is the sender number, and the second parameter message information is cut into three variables: host, time, item

String = sys.argv [2]

Phone_number = sys.argv [1]

Message = string.split (";")

Dict1 = {}

Dict1 ['host'] = message [0]

Dict1 ['time'] = message [1]

Dict1 ['item'] = message [2]

Request.add_query_param ('RegionId', "cn-hangzhou")

Request.add_query_param ('PhoneNumbers',phone_number)

Request.add_query_param ('SignName', "signature name") # fill in the signature name of the application

Request.add_query_param ('TemplateCode', "template CODE") # fill in the applied template CODE

Request.add_query_param ('TemplateParam',dict1)

Response = client.do_action (request)

# python2: print (response)

Print (str (response, encoding = 'utf-8'))

~] # chmod adepx / usr/lib/zabbix/alertscripts/sendsms.py

~] # python / usr/lib/zabbix/alertscripts/sendsms.py Mobile phone number 'official website; 18Drex03Test' # Parameter 1: mobile phone number; Parameter 2:3 parameters are separated by;

5. Zabbix web settings

Management-alarm media type-create media type

Management-user-alarm medium-add

Configure-Action-event Source: trigger-create Action

Message content:

{TRIGGER.NAME}: {TRIGGER.KEY1}; {EVENT.TIME}; {TRIGGER.STATUS}

Finally, a fault test is carried out to verify whether the transmission is successful. Viewing: report-Action Log

Third, the nail group alarms:

Official reference document: https://ding-doc.dingtalk.com/doc#/serverapi2/qf2nxq

1. Nail group, add custom webhook robot, copy webhook address; note that the new version of nail has security settings. Example Select Custom keywords: monitorin

2. Create a script

~] # vim / usr/lib/zabbix/alertscripts/dingding.sh

#! / bin/bash

To=$1

Subject=$2

Text=$3

Curl 'webhook address'\ # the address here is the webhook address of the robot

-H 'Content-Type: application/json'\

-d'

{"msgtype": "text"

"text": {

"content": "" $text ""

}

"at": {

"atMobiles": ["" $1 ""]

"isAtAll": false

}

}'

~] # chmod adepx / usr/lib/zabbix/alertscripts/dingding.sh

~] # chown zabbix:zabbix / usr/lib/zabbix/alertscripts/dingding.sh

~] # bash / usr/lib/zabbix/alertscripts/dingding.sh 1 2 Monitoring # the third parameter must contain a custom keyword, otherwise it fails

3. Set alarm media, users and actions as above.

Script parameters in order are: {ALERT.SENDTO}, {ALERT.SUBJECT}, {ALERT.MESSAGE}

The content of the message is consistent with the email alarm.

The recipient can fill in the mobile phone number.

Finally, a fault test is carried out to verify whether the transmission is successful. Viewing: report-Action Log
