Zabbix 3.2 Install Agent on Linux Rhel 7 - Not connecting to agent

[uncram]

Having issue Install Agent on Linux Rhel 7 for Zabbix 3.2.

First question is how do you match up the exact agent with the specific version of Zabbix. If I have 3.2 how do I pick which agent?

FROM: http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/

I choose 3.2.0.1 but how do you match up with the Server?

zabbix-agent-3.2.0-1.el7.x86_64.rpm 2016-09-14 02:20 333K
[ ] zabbix-agent-3.2.1-1.el7.x86_64.rpm 2016-10-03 15:55 334K
[ ] zabbix-agent-3.2.2-1.el7.x86_64.rpm 2016-12-09 17:20 337K
[ ] zabbix-agent-3.2.3-1.el7.x86_64.rpm 2016-12-22 08:34 338K
[ ] zabbix-agent-3.2.4-1.el7.x86_64.rpm 2017-03-10 19:01 342K
[ ] zabbix-agent-3.2.4-2.el7.x86_64.rpm 2017-03-10 19:01 342K
[ ] zabbix-agent-3.2.5-1.el7.x86_64.rpm 2017-04-26 03:40 343K
[ ] zabbix-agent-3.2.6-1.el7.x86_64.rpm 2017-05-06 16:53 344K
[ ] zabbix-agent-3.2.7-1.el7.x86_64.rpm 2017-07-20 10:12 345K
[ ] zabbix-agent-3.2.8-1.el7.x86_64.rpm

Then I ran

Step 1. rpm -Uvh http://repo.zabbix.com/zabbix/3.2/rh...el7.x86_64.rpm
Step 2. Change config, added Zabbix server and correct HOSTNAME
Step 3. systemctl restart zabbix-agent
Step 4. chkconfig --level 345 zabbix-agent on
Step 5. firewall-cmd --zone=public --add-port=10050/tcp –permanent
Stpe 6. firewall-cmd --reload

RAN :
Ps -C Zabbix_agentd
RAN:
Netsat -ntpl | grep zabbix

Getting Good output, so going back does it matter which version of the agent I install and how to figure out?

My dashboard Get Value from Agent Failed - IP 10050 - Interuppt system call

Checked agent logs files.
Says usual agent start listener

Your agent don't need to be in the same version as your server.

Coudl you perform telnet from server to your host using command

telnet <ip> 10050

You are using IP or DNS ?

This is either a SELinux issue or there is something wrong with your "Server" setting in the agent configuration file. If you are using an IP address there, make sure that the server is actually connecting using this IP address! If you are using a name, make sure that there is a DNS PTR record or a hosts file entry resolving to the aforementioned IP address.
