zabbix3.4原生支持Centos7，
在Centos6上面安装对依赖包的版本有要求
实际安装时遇到很多坑，总结记录一下
Centos6安装选择basic server
yum install httpd
在我的机器上zabbixweb模块不是安装到默认的/var/www下，
而是跑到了/usr/share/zabbix下。
/etc/httpd/conf/http.conf修改
DocumentRoot "/usr/share/zabbix"
<Directory "/usr/share/zabbix">
PHP5.6依赖包安装
rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
