Include instructions for compiling against 3.0.x packaged versions from yum repos

[JCCyC]

Compiling the agent module:

• Download the exact version of the Zabbix sources that correspond to your running version. Mine is 3.0.9, I put it under /root/src
• yum groupinstall "Development Tools"
• yum install dbus-devel libtool gettext autoconf automake
• ./autogen.sh
• ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 --with-zabbix=/root/src/zabbix-3.0.9 (omit --libdir switch if 32 bit machine; replace src download path with your own)
• make && make install
• service zabbix-agent restart
• pidof zabbix_agentd to see if it's running properly

Importing template XML into zabbix:

• Edit version tag from 3.2 to 3.0
• Remove empty <httptests /> tag

Example template has been downgraded to 2.0 version, so any supported Zabbix version should import it without any problem. Commit b210bda.
