zabbix自动注册，实现自动添加机器，减少人工干预

1.zabbix_agent的安装配置：

vim install_zabbix_agent.sh 

#!/bin/bash
#author:chenjianwen

RealIP=`curl -s http://members.3322.org/dyndns/getip`
## 若zabbix服务端地址改变，修改此处即可
zabbix_server_ip=115.xx.xx.xx

yum_list_install(){
        yum install -y pcre pcre-devel
}

backup_agent_old(){
        killall -9 zabbix_agentd
        mv /usr/local/zabbix /usr/local/zabbix-old
}

scp_agent(){
        scp -r 115.xxx.xxx.xxx:/data/source/zabbix-3.4.5.tar.gz .
        tar xvf zabbix-3.4.5.tar.gz
}

install_agent(){
        cd zabbix-3.4.5
        ./configure --prefix=/usr/local/zabbix --enable-agent
        if [ $? == 0 ];then
                make -j 4
                if [ $? == 0 ];then
                        make install
