2. Installation configuration
. the repo package of Centos7 version is used here:
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
Because there are installation packages locally, the software warehouse can be configured directly. If necessary, it can be downloaded from the official website
[zabbix] name=Zabbix Official Repository - $basearch baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/ enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=https://mirrors.aliyun.com/zabbix/non-supported/rhel/7/x86_64/ enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=0
yum install zabbix-server-mysql yum install -y mariadb-server systemctl enable --now mariadb.service
The database needs to be safely initialized
mysql mysql> create database zabbix character set utf8 collate utf8_bin; mysql> create user 'zabbix'@'localhost' identified by 'westos'; mysql> grant all privileges on zabbix.* to 'zabbix'@'localhost';
Use MySQL to import the initial database schema and data of Zabbix server,
zcat /usr/share/doc/zabbix-server-mysql-4.0.27/create.sql.gz | mysql -uzabbix -pwestos zabbix
Edit ZABBIX_ The server.conf file to use the created database.
Enter the Zabbix database password created by MySQL in the DBPassword parameter.
vim /etc/zabbix/zabbix_server.conf edit the following
DBHost=localhost DBName=zabbix DBUser=zabbix DBPassword=westos
Run the following command to start the Zabbix server process:
systemctl enable --now zabbix-server netstat -antlp
Query whether port 10051 is enabled
Run the following command to install the Zabbix agent
yum install zabbix-agent -y systemctl enable --now zabbix-agent
Configuring the ZABBIX front end
yum install php-bcmath -y yum install php-mbstring -y yum install zabbix-web-mysql -y
After downloading, the configuration file:
The Apache configuration file for the Zabbix front end is located in / etc/httpd/conf.d/zabbix.conf.
vim /etc/httpd/conf.d/zabbix.conf php_value date.timezone Asia/Shanghai systemctl enable --now httpd
Set the correct time zone.
Visit on Web page http://172.25.76.7/zabbix
Select next: enter the database password
Next: the name is zabbix server
Next, start logging in. The user is Admin and the password is zabbix
We can choose Chinese by clicking this villain's Avatar:
Then select Configure host to see
We only need one package to install agent on server 5 and 6
We directly pass the yum source to server56
yum install zabbix-agent.x86_64 -y systemctl enable --now zabbix-agent.service
vim /etc/zabbix/zabbix_agentd.conf #Three amendments Server=172.25.76.7 ServerActive=172.25.76.7 Hostname=server5 systemctl restart zabbix-agent.service
If there is 10050, it will be opened successfully
There are three ways to add hosts
1. Add host manually
Select Linux servers for the group
Then select the template:
Select Template OS Linux in the link selector
Click Update directly after the change:
Configuration, host. When the status shown in the figure below appears, the data information in the view drawing indicates that the addition is successful,
2. Add host automatically
We need to use server6 just configured
Same as the previous server2 configuration
Action – > auto discovery – > start
The one on the far right is disabled. Click it to open it
Then the automatic discovery configuration is as follows:
The point update becomes like this
Then click auto discovery to find the server
Then we go to configure the host and check it. We can see that server3 is already in the host group
3. Automatic registration
In order to save resources, we directly delete the server6 just added, and then disable the automatically discovered rules
Now test automatic registration
Actions – > auto registration – > action hostname – > actions – > associated with adding to host group module
Click enable to turn auto discovery into disabled
Then, action, select automatic registration in the upper right corner
Select configuration, action!
Remember to add certain trigger conditions
Then click action
Insert picture description here and click New
Remember to add the key points after selecting the template
Then select a new template
Select two new templates and select update when finished
Let's go to the host to check whether the addition is successful. If it does not appear, restart the following services
Execute the following command on server6
systemctl restart zabbix-agent.service
Still configuring the host, check:
