zabbix2.2升级到zabbix3.0.2
1、操作系统环境# cat /etc/issue
CentOS release 6.4 (Final)
Kernel \r on an \m
# uname -r
2.6.32-358.el6.x86_64
# uname -m
x86_64
备份备份。。
# cp -a /usr/share/zabbix /tmp/zabbix.bak
备份数据库，也可以使用mysqldump命令等等。
# cp /var/lib/mysql /tmp/mysql.bak
备份zabbix_server.conf文件
# cp /etc/zabbix/zabbix_server.conf /tmp/zabbix_server.conf.bak
2、Zabbix 3.x对PHP的要求最低为5.4，而CentOS6默认为5.3.3，完全不满足要求，故需要利用第三方源，将PHP升级到5.4以上，注意，不支持PHP7
3、安装php第三方源，并安装相应php版本
