1、基础环境准备
安装zabbix的yum源，这里有必要提一点，阿里的yum源已经提供了zabbix3.0
1.1、yum源配置
rpm -ihv http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm
1.2、zabbix_agent安装配置
yum install zabbix-agent -y
vim /etc/zabbix/zabbix_agentd.conf
Server=server端ip地址 #用于被动模式，数据获取
ServerActive=server端ip地址 #用于主动模式，数据提交 /etc/init.d/zabbix-agent start #启动zabbix agent
这里的主动模式还有被动模式的出发点都是agent端，所以agent主动向server端发送数据就成为主动模式，而等待server端主动获取数据则称为被动模式。
agent端安装比较简单.至此已经安装完毕，下来就是在server端添加agent端.
zabbix客户端自动安装脚本
考虑脚本的通用性，设置的手工输入zabbixserverIP这个变量。
#!/bin/bash
#suto install zabbix_agentd
#author :swh
echo "Now this shell will install zabbix_agentd autoly:please wait"
yum install net-snmp-devel libxml2-devel libcurl-devel -y
echo "add zabbix group and user:"
groupadd zabbix
useradd -r zabbix -g zabbix -s /sbin/nologin
echo "download package -make and make install "
cd /usr/local/src
wget -c "http://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.0.3/zabbix-3.0.3.tar.gz"
tar -xzvf zabbix-3.0.3.tar.gz
cd zabbix-3.0.3
./configure --prefix=/usr/local/zabbix-3.0.3/ --enable-agent
make
make install
ret=$?
if [ $? -eq 0 ]
then
read -p "please input zabbix_serverIP:" zabbix_serverIP
sed -i 's/Server=127.0.0.1/Server='$zabbix_serverIP'/' /usr/local/zabbix-3.0.3/etc/zabbix_agentd.conf
sed -i 's/ServerActive=127.0.0.1/ServerActive='$zabbix_serverIP'/' /usr/local/zabbix-3.0.3/etc/zabbix_agentd.conf
sed -i 's/Hostname=Zabbix server/Hostname='$HOSTNAME'/' /usr/local/zabbix-3.0.3/etc/zabbix_agentd.conf
echo "zabbix install success,you need set hostname: $HOSTNAME" else
echo "install failed,please check"
fi
/usr/local/zabbix-3.0.3/sbin/zabbix_agentd
if [ $? -eq 0 ]
then
echo "set zabbix_agentd start with system"
echo "/usr/local/zabbix-3.0.3/sbin/zabbix_agentd start" >> /etc/rc.d/rc.local
else
echo "start error,please check"
fi
