Centos 7 compile and install zabbix-agent2

summarize Zabbix agent 2 is a new generation of Zabbix agent that can be used in place of Zabbix agent.Zabbix agent 2 has been developed for:

• Reduce the number of TCP connections
• Provide improved check concurrency
• Easy Extension with Plugins
• Provides simple checks consisting of only a few simple lines of code
• Provide complex checks consisting of long-running scripts and independent data collection with regular data returns
• is a direct replacement for the Zabbix agent (as it supports all previous features)

Agent 2 is written in the Go programming language (reusing some C code from the Zabbix agent).Building Zabbix Agent 2 requires a configured Go environment with a currently supported version of Go Official Documentation Portal

2
tar -xvf go1.19.5.linux-amd64.tar.gz -C /usr/local/
3
echo "export PATH=/opt/go/bin:$PATH" >> /etc/profile.d/go.sh
4
echo "export GO111MODULE=on" >> /etc/profile.d/go.sh
5
echo "export GOPROXY=https://goproxy.cn,direct" >> /etc/profile.d/go.sh
6
source /etc/profile

Configuring and compiling the zabbix-agent2 installation environment

(1)、Installing the pcre library yum install pcre-devel (2)、Upgrading the GCC version
