The latest version of ZABBIX 4.2 updates a lot of features, among which the hostname that controls auto-discovery eliminates the worry of manual renaming when automatically discovering network devices, which is a very useful feature, especially when using Zabbix or SNMP agents to achieve a large degree of automation.

For more detailed information on the new features, please refer to the Zabbix website: https://www.zabbix.com/cn/whats_new_4_2

Now let's start building Zabbix4.2:

Environment configuration: permanently shut down selinux:

Sed-I "s/SELINUX=enforcing/SELINUX=disabled/g" / etc/selinux/config

Turn off the firewall and do not boot:

Systemctl stop firewalld.servicesystemctl disable firewalld.service first adds the Zabbix-yum source:

Rpm-Uvh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm

Here my system is centos7, so the link is zabbix/4.2/rhel/7/. If it is 6, you can change it to zabbix/4.2/rhel/6/.

two。 Install the zabbix server:

Yum-y remove mariadb-libs # Uninstalls databases that conflict with mysql

Yum-y install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get Note: when Error downloading appears, it may be caused by the instability of the Yum source network. You can re-enter the command breakpoint to resume transmission, or install a single yum package.

3. Install and configure the mysql database:

Wget-c https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpmrpm-ivh mysql80-community-release-el7-1.noarch.rpmyum-y install yum-utilsyum-config-manager-- disable mysql80-community # shielded 8.0 source package yum-config-manager-- enable mysql57-community # Open version 5.0 source package yum install mysql-community-server-y create data storage folder: mkdir-p / data/zabbix/chown-R mysql:mysql / data

Wait for the download and installation to complete:

Start mysql

Systemctl start mysqld

Boot up

Systemctl enable mysqld

Modify the mysql storage path:

Vi / etc/my.cnf

Datadir=/data/zabbix

Add: skip-name-resolve # disable automatic DNS parsing

Check the root temporary password and log in to mysql to change the password:

Grep 'temporary password' / var/log/mysqld.log

Mysql-uroot-p

ALTER USER 'root'@'localhost' IDENTIFIED BY' password

Create zabbix users and databases in the database:

Create database zabbix character set utf8 collate utf8_bin;grant all privileges on zabbix.* to zabbix@localhost identified by "Zabbix@123"

Import zabbix raw data into the database after exiting mysql

Zcat / usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql-uzabbix-paired Zabbix upload 123' zabbix

Zabbix service configuration:

Change the configuration parameters: vi / etc/zabbix/zabbix_server.conf

Modified items: DBName, DBUser, DBPassword, StartVMwareCollectors, Timeout, CacheSize

Change the time zone:

Sed-i.ori '19a php_value date.timezone Asia/Shanghai' / etc/httpd/conf.d/zabbix.conf

It can solve the garbled characters in the graphic list:

Yum-y install wqy-microhei-fonts

Mv / usr/share/fonts/dejavu/DejaVuSans.ttf / usr/share/fonts/dejavu/DejaVuSans.ttf.bak

Cp-f / usr/share/fonts/wqy-microhei/wqy-microhei.ttc / usr/share/fonts/dejavu/DejaVuSans.ttf

Set self-boot:

Systemctl enable zabbix-server httpd

Start zabbix:

Systemctl start zabbix-server httpd

Enter the zabbix-web http:// server ip/zabbix to detect OK

Set server information: Port 0 is the default port 3306

The initial account password is Admin zabbix

After logging in, you can set Chinese in the user settings:

LDAP authentication configuration: first create an account that matches the domain user: (note that permissions are given to Super Admin permissions)

Configure LDAP:

Now that the basic environment for ZABBIX is set up, let's create auto-discovery rules: create discovery rules in the configuration; auto-discovery menu:

Scan the network segment 172.16.57.0 to check the address ping in the segment and check whether the OID information of the device SNMP has this field: SNMPv2-MIB::sysName.0.

* SNMP community enter the community name of SNMP

Check OID: SNMPv2-MIB::sysName.0

Finish adding the discovery rules, and then create an automatic discovery action to define the actions to be performed after discovery:

Create actions in the configuration actions menu: add appropriate conditions and actions

After completing the action discovery configuration, the host named by the device name is automatically added after a period of time.
