Solve the garbled characters in the graphical interface
1. Control Panel-->Fonts-->Select a Chinese font such as "Kaiti" (simkai.ttf)
2. Upload our downloaded fonts to the /usr/share/zabbix/fonts directory on the zabbix server side

4. After saving and exiting, refresh the interface to display normally
zabbix email alarm
1. Install the package
[root@localhost ~]# yum -y install mailx
2. Set permissions for the /bin directory
[root@localhost ~]# Chown -R zabbix.zabbix /bin/mail
3. Edit /etc/mail.rc
[root@localhost ~]# vim /etc/mail.rc
set smtp=smtp.163.com
set [email protected] #Email account
set smtp-auth-password=cheng12345 #Client authorization code
set smtp-auth=login
4. Test whether there is a problem with the mailx configuration
[root@localhost ~]# echo test | mail -s "my name is chengwangan" [email protected] #This inbox is for receiving mail
5. Edit zabbix_server.conf, configure the script storage directory
[root@localhost zabbix]# cd /etc/zabbix/
[root@localhost zabbix]# vim zabbix_server.conf
AlertScriptsPath=/usr/lib/zabbix/alertscripts #Here I choose the default directory

12. Testing
After we close zabbix_agentd, see if we can receive an email alert
[root@localhost alertscripts]# systemctl stop zabbix-agent.service
An error is reported here, the script does not have permission to execute, we need to give the script 555 permission
[root@localhost alertscripts]# chmod 555 mailx.sh
Start zabbix-agent, stay for a minute, then close and re-trigger
[root@localhost alertscripts]# systemctl start zabbix-agent.service
[root@localhost alertscripts]# systemctl stop zabbix-agent.service
The email has been sent, we log in to 163 mailbox to check
zabbix-agent client installation
1. Install zabbix-agent
#Agent side
[root@localhost ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-agent-3.0.4-1.el7.x86_64.rpm
2. Backup and change the zabbix-agent configuration file
[root@localhost ~]#cp /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.conf_$(date +%F)
[root@localhost ~]# sed -i 's/Server=127.0.0.1/Server=192.168.0.125/g' /etc/zabbix/zabbix_agentd.conf
[root@localhost ~]# sed -i 's/ServerActive=127.0.0.1/ServerActive=192.168.0.125/g' /etc/zabbix/zabbix_agentd.conf
4. Modify zabbix-agent.conf information
[root@localhost ~]# vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.4.182 #Fill in the Server IP
ServerActive=192.168.4.182 #Fill in the monitor IP
Hostname=zabbix server #Fill in the username when the monitor side created the host
5. Set up self-start at boot and start the zabbix client
systemctl start zabbix-agent
systemctl enable zabbix-agent
#Server side
1. Add the identity information of the monitored host
Interface operation: Configuration-->Host-->Create host
Fill in the Agent information
The hostname must be the same as the Hostname on the Agent side
The Agent port must be the same as the Server=XXX.XXX.XXX.XXX on the Agent side
2. Click on the template next to the host to add the following
Template App Zabbix Server
Template OS Linux
3. When ZBX turns green, it means we have successfully monitored this host
4. Monitor-->Graphics-->Select the host you just created, let's take a look at its network card traffic trend
