重点
Nginx配置文件 fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; 这一行需要改成fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
否则界面访问PHP文件会报File not Found的错误，Nginx后台日志也会报Primary script unkNown" while reading response header from upstream的报错，$document_root 代表当前请求在root指令中指定的值，更改后重启Nginx服务即可恢复正常访问。
直接在/usr/local/Nginx/html 目录中新建index.PHP和MysqL_connect.PHP
[root@server1 html]# cat index.PHP
<?PHP
PHPinfo();
?>
[root@server1 html]#
[root@server1 html]# cat test.PHP
<?PHP

如果要zabbix服务器支持监控JAVA应用程序的性能需要事先在服务端安装java编译环境然后启用—enable-java 参数
[root@server1 zabbix-4.2.1]# rpm -ivh /home/ipnet/jdk-7u80-linux-x64.rpm
如果需要监控服务器硬件可以加上 –with-openipmi 参数，这个需要事先安装好OpenIPMI和OpenIPMI-devel RPM包，也可以用SNMP来监控服务器硬件，我因为是用的SNMP来获取服务器硬件信息，这里我没有将这个功能编译进去。
编译zabbix服务端应用
[root@server1 zabbix-4.2.1]# ./configure --prefix=/usr/local/zabbix-3.4.1 --enable-server --enable-agent --with-MysqL --with-net-snmp --with-libcurl --with-libxml2 --with-openssl --enable-java --enable-ipv6

浏览器打开zabbix配置界面
下面的要求都需要是OK状态再继续。
配置数据库连接，当主机填写为localhost时MysqL会采用 unix domain socket连接，当主机填写为127.0.0.1时MysqL会采用TCP/IP的方式连接，如果页面报的错误是No such file or directory，也就是说PHP找不到这个socket文件，这个时候需要修改PHP.ini指定MysqL的socket文件位置
具体可以看https://segmentfault.com/q/1010000000328531 这个博文
首先my.cnf看下socket文件的位置
[root@server1 no-debug-non-zts-20160303]# cat /etc/my.cnf|grep socket
socket=/var/lib/MysqL/MysqL.sock
[root@server1 no-debug-non-zts-20160303]# egrep 'MysqLi.default_socket' /usr/local/PHP-7.1.29/etc/PHP.ini
MysqLi.default_socket = /var/lib/MysqL/MysqL.sock
[root@server1 no-debug-non-zts-20160303]#
按照提示下载下来再传到对应服务器位置刷新界面即可
最终打开的界面如下：
