Zabbix installation repository

rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

Bay install Zabbix server, client, agent

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent

Creating the initial database:

# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to 'zabbix'@'%' identified by 'zabbix';
mysql> source create.sql;
mysql> quit;

Zabbix configuration database server

vim /etc/zabbix/zabbix_server.conf

Edit the file /etc/httpd/conf.d/zabbix.conf, uncommented and set the correct time zone for you.

vim /etc/httpd/conf.d/zabbix.conf

在：# php_value date.timezone Europe/Riga

　加：php_value date.timezone Asia/Shanghai

After you install normal zabbix, after logging zabbix monitoring error zabbix server is not running: the information displayed may not be current

The following scenarios are likely to cause this error,

1. selinux is closed. Be sure to close the open selinux will cause a series of problems, even zabbix the discovery function can not be used normally

Close SELinux method:

Temporary closure: setenforce 0

Permanent closure: vi / etc / selinux / config

Note:

setenforce 1 becomes enforcing mode setting SELinux

setenforce 0 becomes permissive mode setting SELinux

Increase in the startup parameters lilo or grub of: selinux = 0, can also turn off selinux

Turn off the firewall

Temporary closure: systemctl stop firewalld.service

Permanent closure: systemctl disable firewalld.service

1. Installation Agent (disposed on the target host monitoring)

rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

Installation method and installation as zabbix

yum install zabbix-agent zabbix-sender -y

Modify agent profiles

vim /etc/zabbix/zabbix_agentd.conf

vim /etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid

LogFile=/var/log/zabbix/zabbix_agentd.log

LogFileSize=0

Server = 192.168.2.76  monitoring servers which host

ListenIP=0.0.0.0

Home Agents = 3

ServerActive = 127.0.0.1 monitored servers which host

Hostname = node1 monitored host name

Start agent service

systemctl start zabbix-agent

Then the monitor included in the manual zabbix web interface Host Host

I remember being monitored host is down: selinux.
