flush privileges;
exit
mysql -u root -p'xxxx'
create database zabbix character set utf8 collate utf8_bin;
grant all on zabbix.* to zabbix@'localhost' identified by 'xxxx';
exit
安装php5.6（要求php5.6以上）：
rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

cp -rv /usr/share/doc/zabbix-web-4.0.4/httpd22-example.conf /etc/httpd/conf.d/zabbix.conf
vi /etc/httpd/conf.d/zabbix.conf
