在机器上已经安装好了Grafana容器，zabbix-web-Nginx-MySQL容器，镜像都是从官网下载官方制作的镜像，grafana配置zabbix数据源也是很简单的（grafana官网写的也很清楚）。下面就到了?这个配置数据源画面：

修改API地址，输入zabbix用户的密码，接着我点下确定。这时我陷入了一个深坑，报错了！！！

浏览器查看报错信息如下：

我惊异了跨域请求问题？？？原来用实体机装没有出现过这个问题啊！！！

一开始看到跨域请求问题在想是不是因为Nginx没有设置跨域问题，百度一整在配置文件增加了跨域的配置，还是不行！！！

索性直接再起一个httpd的zabbix web 容器试试，我擦还是不行！！！

再次，再次又研究了一下请求和响应如下：

response

File not found.

我擦文件没找到，咋回事！！！

服务器上有api_jsonrpc.php文件啊！！！

就在我在绝望时，名侦探柯南说他用curl调用成功了啊！！！

柯南代码?

curl -s -X POST -H 'Content-Type:application/json' -d '{"jsonrpc": "2.0","method": "user.login","params": {"user": "Admin","password": "zabbix"},"id": 1}' http://localhost:80/api_jsonrpc.php

我心想这就更诡异了，我咋用curl调不成功呢！！！

我的代码?

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"user.login","params":{"user":"Admin","password":"zabbix"},"auth":null,"id":0}' http://zabbix-web-nginx-mysql-8/zabbix/api_jsonrpc.php;

我擦难道是“-i"和”-s“参数不一样导致柯南可以跑通？？？百度了一下这两个参数没啥用！！！

擦擦擦！！！正在百思不得其解的时候，发现两个URL不一样！！！

由于zabbix-web容器PHP文件存放的层级变了，导致API的URL也变了，少了zabbix这个层级。

其实在初始页面也可以看出这一点：

平时我们登录地址是http://ip/zabbix/

容器版的web服务直接http://ip/就可以打开登录页面。

终于活着出坑啊！！！
