Zabbix3.2 monitoring tool

Zabbix is an enterprise-level open source tool for distributed system monitoring and network monitoring based on the WEB interface.

Zabbix can monitor various network parameters, ensure the safe operation of the server system, and provide a flexible notification mechanism for administrators to quickly locate / solve various problems.

Zabbix consists of three parts: Zabbix_Server server, Zabbix_Agent client and Zabbix_proxy proxy.

Zabbix_Server: monitoring the status of remote servers / networks can be provided through methods such as SNMP,Zabbix_Agent,Ping,SNMP.

Zabbix_Agent: it is used to collect client server data and give it to Zabbix_Server for processing.

Zabbix_Proxy: cache synchronization server monitoring data.

The main functions of Zabbix: CPU load, memory usage, disk usage, network condition, port monitoring, log monitoring.

Monitoring architecture of Zabbix:

Zabbix deployment steps:

Environmental requirements: it must be supported by LNMP/LAMP environment and above version of PHP5.4.

# systemctl stop firewalld # turn off firewalld Firewall

# systemctl disable firewalld.service # disable self-startup of firewalld service

# sed-I-e's | SELINUX=enforcing | SELINUX=disabled |'/ etc/selinux/config # disable SELINUX

# sed-I-e's | SELINUXTYPE=targeted | # SELINUXTYPE=targeted |'/ etc/selinux/config

# setenforce 0

Source code compilation method:

V install related dependent components

# yum-y install php php-gd php-mysql php-bcmath php-mbstring php-xml curl curl-devel gcc gcc-c++ net-snmp net-snmp-devel perl-DBI httpd mariadb* # YUM deploy LAMP environment

V unpack the installation package

# tar xzvf zabbix-3.2.1.tar.gz

# cd zabbix-3.2.1

V compile and install Zabbix

Install Server and Agent, and support putting data into the MYSQL database:

#. / configure-prefix=/usr/local/zabbix-enable-server-enable-agent-with-mysql-enable-ipv6-with-net-snmp-with-libcurl

Install only Server and support putting data into the MYSQL database:

#. / configure-prefix=/usr/local/zabbix-enable-server-with-mysql-with-net-snmp-with-libcurl

Install only the Proxy agent and support putting data into the MYSQL database:

#. / configure-prefix=/usr/local/zabbix-enable-proxy-with-net-snmp-with-mysql-with-ssh3

Install only the Agent client:

#. / configure-enable-agent

# make & & make install

Note:-- with-libcurl: monitor WEB page response time and download speed.

V authorize Zabbix database users

# systemctl start mariadb # start MYSQL

# mysqladmin-u root password 123 # set database ROOT user password

# mysql-u root-p123 # Log in to database

Mysql > create database zabbix character set UTF8; # create the zabbix database and specify the encoding as UTF8

Mysql > grant all on zabbix.* to 'zabbix'@'localhost' identified by' 123' with grant option

Mysql > flush privileges; # authorizing zabbix users and Refresh Authorization

Mysql > exit

V import the SQL file that comes with Zabbix into the database

# mysql-u zabbix-p123 zabbix

Installation troubleshooting

Failure 1: MYSQL database version is too high; solution: reinstall suitable MYSQL database

Note: Current database version: current version Required mandatory version: mandatory version number

Fault 2: user authorization problem; solution: re-authorize Zabbix database users

Fault 3: database problem solution: re-import the corresponding database of Zabbix

Fault 4: the solution to the problem of too many server processes: set the parameters related to the configuration file to control the process

Note: Too many processes on Zabbix server: there are too many processes in the Zabbix server

Failure 5: low number of threads when Zabbix_server starts resulting in polling load workaround: StartPollers is set to 5 or 10

Fault 6: Zabbix_server is running but prompt is not running solution: turn off SELinux

Failure 7: database password error solution: modify the configuration file zabbix.conf.php
