1、 找不到url
2、 服务器无法处理当前请求，PHP解析出错
3、 服务器无法处理当前请求，权限不足
1、 找不到url
浏览器报错：The requested URL /zabbix/ was not found on this server
日志报错：File does not exist: /var/www/html/zabbix
原因：Apache缺少指向/usr/share/zabbix相关目录的配置文件
解决办法：配置/etc/httpd/conf.d/zabbix.conf文件内容如下
mv /etc/httpd/conf.d/zabbix.conf{,.bak} cat >>/etc/httpd/conf.d/zabbix.conf<<EOF # # Zabbix monitoring system php web frontend # Alias /zabbix /usr/share/zabbix <Directory "/usr/share/zabbix"> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all <IfModule mod_php5.c> php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value max_input_vars 10000 php_value date.timezone Asia/Shanghai </IfModule>
</Directory>

</Directory> EOF /etc/init.d/httpd restart
2、 服务器无法处理当前请求，PHP解析出错
浏览器报错：10.0.0.106 is currently unable to handle this request.
日志报错：PHP Parse error: syntax error, unexpected '[' in /usr/share/zabbix/index.php on line 32
原因：PHP版本太低，需要安装PHP5.4以上的版本
解决办法：CentOS6默认yum安装的是php5.3，需要构建yum源安装或进行源码安装高版本PHP
配置命令
yum remove php php-mysql php-cli php-xml php-gd php-common php-bcmath php-pdo php-mbstring -y rpm -qa|grep php rpm -i https://mirror.webtatic.com/yum/el6/latest.rpm
yum install php55w php55w-mysql php55w-cli php55w-xml php55w-gd php55w-common php55w-bcmath php55w-pdo php55w-mbstring -y php -v
3、 服务器无法处理当前请求，权限不足
浏览器报错：10.0.0.106 is currently unable to handle this request.
日志报错：PHP Fatal error: require_once(): Failed opening required '/etc/zabbix/web/maintenance.inc.php' (include_path='.:/usr/share/pear:/usr/share/php') in /usr/share/zabbix/include/classes/core/ZBase.php on line 276
原因：apache对/etc/zabbix/web/maintenance.inc.php文件的权限不足导致处理中断
解决办法：更改/etc/zabbix/web/目录的属主
解决命令：
chown -R apache. /etc/zabbix/web/
/etc/init.d/httpd restart ls -l /etc/zabbix/web/
