Zabbix monitoring deployment scenario

Objective:

Build a monitoring environment for the data center

Initialize the system auto-talk script init.sh

Deployment of LAMP environment

To install the compilation environment, install lamp or lnmp using an one-click installation script

# Note: when using the script, you should pay attention to whether the software link is invalid or not, so as to avoid installation failure.

Lamp Security and Optimization:

1. Configure disable_function to disable some functions

Disable_functions = eval,assert,popen,passthru,escapeshellarg,escapeshellcmd,passthru,exec,system,chroot,scandir,chgrp,chown,escapeshellcmd,escapeshellarg,shell_exec,proc_get_status,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,leak,popepassthru,stream_socket_server,popen,proc_open,proc_close

2.Mysql configuration

Turn on each tablespace

Login:

# / usr/local/mysql/bin/mysql-S / data/mysql/mysql.sock

Mysql > use mysql

Mysql > update user set password=password ('123456') where user = 'root'

Mysql > flush privileges

/ usr/local/mysql/bin/mysql-uroot-p123456-S / data/mysql/mysql.sock

Download address of Zabbix:

Wget http://ncu.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.0.4/zabbix-3.0.4.tar.gz

Create and import zabbix database

Mysql > create database zabbix character set utf8

Grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'; # create zabbix user

Flush privileges; # refresh the system authorization table again

Use zabbix # enter the database

Select database (); # View the current database

Source / usr/local/src/zabbix-3.0.4/database/mysql/schema.sql # Import script file to zabbix database

Source / usr/local/src/zabbix-3.0.4/database/mysql/p_w_picpaths.sql # Import script file to zabbix database

Source / usr/local/src/zabbix-3.0.4/database/mysql/data.sql # Import script file to zabbix database

Note: please import in the above order, otherwise you will make an error.

Install zabbix

1. Add users:

Because secure zabbix can only be run by ordinary users

Groupadd zabbix # create user group zabbix

Useradd-M zabbix-s / sbin/nologin

Useradd zabbix-g zabbix-s / bin/false # create the user zabbix and add the user zabbix to the user group zabbix

Cd / usr/local/src/zabbix-3.0.4/ # enter the installation directory

/ configure-- prefix=/usr/local/zabbix-- enable-server-- enable-agent-- with-net-snmp-- with-libcurl-- enable-proxy-- with-mysql=/usr/bin/mysql_config

-- enable-java # supports jmx to monitor java processes

Make # compilation

Make install # installation

Description: find /-name mysql_config search location. If there is no mysql_config, you need to install yum install mysql-devel.

Modify zabbix configuration file

Cd / usr/local/zabbix/etc

Vi etc/zabbix_server.conf

DBName=zabbix # Database name

DBUser=zabbix # Database user name

DBPassword=123456 # database password

ListenIP=127.0.0.1 # Database ip address

AlertScriptsPath=/usr/local/zabbix/share/zabbix/alertscripts # zabbix run script storage directory

: wq! # Save exit

Vi / home/sxit/zabbix/etc/zabbix_agentd.conf

Include=/home/sxit/zabbix/etc/zabbix_agentd.conf.d/

UnsafeUserParameters=1 # enable custom key

: wq! # Save exit

6. Add boot script

Cp / usr/local/src/zabbix-3.0.4/misc/init.d/fedora/core/zabbix_server / etc/init.d/zabbix_server # server

Cp / usr/local/src/zabbix-3.0.4/misc/init.d/fedora/core/zabbix_agentd / etc/init.d/zabbix_agentd # client

Chmod + x / etc/init.d/zabbix_server # add script execution permissions

Chmod + x / etc/init.d/zabbix_agentd # add script execution permissions

Chkconfig zabbix_server on # add Boot Boot

Chkconfig zabbix_agentd on # add Boot Boot

Modify the zabbix installation directory in the zabbix boot script

Vi / etc/rc.d/init.d/zabbix_server # Editing server configuration file

BASEDIR=/home/sxit/zabbix/ # zabbix installation directory

: wq! # Save exit

Vi / etc/init.d/zabbix_agentd # Editing client profile

BASEDIR=/home/sxit/zabbix/ # zabbix installation directory

: wq! # Save exit

3. Configure web site

Cd / home/sxit/zabbix-3.0.3

Cp-r / usr/local/src/zabbix-3.0.4/frontends/php / usr/local/apache/htdoc/zabbix

Chown daemon.daemon-R / usr/local/apache/htdoc/zabbix

Note: / home/sxit/apache/htdoc/ is apache default site directory daemon is apache running account

Service zabbix_server start # start the zabbix server

Service zabbix_agentd start # start the zabbix client

4. Modify php configuration file parameters

1. Vi / etc/php.ini # Editing and modifying

Post_max_size = 16m

Max_execution_time = 300

Max_input_time = 300

: wq! # Save exit

PHP databases supportoffFail

Php databases support off fail is missing mysqli after query.

Install mysqli

The module needs to be compiled in the php source code and then loaded

/ usr/local/php/bin/phpize

. / configure-- prefix=/usr/local/php/mysqli\

-- with-php-config=/usr/local/php/bin/php-config\

-- with-mysqli=/usr/bin/mysql_config

Make & & make install

Installing shared extensions: / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

Installing header files: / usr/local/php/include/php/

Edit php.ini

# vi etc/php.ini

Add a line at the end:

Extension= / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/mysqli.so

Restart the http service

Note: this may return: / usr/local/src/php-5.6.6/ext/mysqli/mysqli_api.c:36:47: error: ext/mysqlnd/mysql_float_to_double.h: No such file or directory

Direct modification: the path of line 36 of mysqli/mysqli_api.c file is absolute

Include "/ usr/local/src/php-5.6.6/ext/mysqlnd/mysql_float_to_double.h"

PHP gettextoffWarning

Manually compile and install the gettext module

Cd / usr/local/src/php-5.6.6/ext/gettext

# / usr/local/php/bin/phpize

#. / configure-with-php-config=/usr/local/php/bin/php-config

# make & & make install

After installation, an informational prompt similar to this is generated:

Installing shared extensions: / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

Edit php.ini

# vi etc/php.ini

Add a line at the end:

Extension= / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/gettext.so

Restart the http service

Question:

Zabbix server is runningNo10.0.8.153:10051

Zabbix server is not running:the information displayed may not be current

1. Look for allow_url_fopen = On in the php.ini file

Let your php support opensll extensions

/ usr/local/php/bin/phpize

. / configure-with-openssl-with-php-config=/usr/local/php/bin/php-config

Installing shared extensions: / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

Add a line at the end:

Extension= / usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/openssl.so

2. Just turn on the fsockopen function

Disable_function, remove pfsockopen.

5. Install web

Open in the browser:

Http://10.0.8.153/zabbix/setup.php

Login:

Default user name: Admin

Password: zabbix

Zabbix agent installation:

. / configure-prefix=/usr/local/zabbix_agent-enable-agent

Make & & make install

Cp / usr/local/src/zabbix-3.0.4/misc/init.d/fedora/core/zabbix_agentd / etc/init.d/zabbix_agentd # client

Chmod + x / etc/init.d/zabbix_agentd

Chkconfig zabbix_agentd on

Modify the installation directory: vim / etc/init.d/zabbix_agentd

BASEDIR=/usr/local/zabbix_agent/

Zabbix client configuration

Configure the zabbix_server configuration file under the zabbix source directory

# vim / usr/local/zabbix_agent/etc/zabbix_agentd.conf

Server=127.0.0.1 (note that the above client needs to be modified to the IP address of the monitor)

ServerActive=127.0.0.1 (note that the above client needs to be modified to the IP address of the monitor)

Hostname=Zabbix server (the name here needs to be the same as that configured on the monitor)

Both Server and ServerActive specify the IP address of zabbixserver, but the difference is that the former is passive and the latter is active. In other words, the configuration of Server is used to allow 127.0.0.1 this ip to come to me to get data. ServerActive 127.0.0.1 means that the client actively submits data to him. Do you get it? Why should there be a distinction between active and passive? We will discuss this issue later!

Zabbix agent detection can be divided into two forms: active (agent active) and passive (agent). Both active and passive are discussed relative to agent. Briefly explain the difference between active and passive as follows:

Initiative: agent requests server to obtain a list of active monitoring items, and actively submits the data to be detected in the monitoring items to server/proxy

Passive: server requests agent to obtain data of monitoring items, and agent returns data.

Active configuration: monitoring clients actively send data

Server 192.168.18.223 ip (server side)

ServerActive 192.168.18.223 10051 monitor side ip: Port

Hostname=Zabbix server (the name here needs to be the same as that configured on the monitor)

Passive configuration: monitoring server actively collects data

Server 192.168.18.223 ip (server side)

ServerActive 192.168.18.22x:10050 monitored end ip: Port

Hostname=192.168.18.22x (the name here needs to be the same as that configured on the monitor)

Test, the following command needs to be executed on the server side, where 10.0.8.152 is the ip of agent

# / usr/local/zabbix/bin/zabbix_get-s 10.0.8.152-p10050-k "system.host"

11163875

# / usr/local/zabbix/bin/zabbix_get-s 10.0.8.152-p10050-k "system.hostname"

HOSTNAME
