python客户端初始化失败

Open dutyu opened this issue 4 years ago • 8 comments

python客户端启动时没有解析/cat/appdatas/cat/client.xml的内容，看日志是尝试连接了本机的2280端口，配置文件的权限也是OK的，同一台机器，java客户端就没有问题

日志如下： 2020-02-27 06:02:07 PM [19408][[INFO] ] Cat log module has been successfully initialized. 2020-02-27 06:02:07 PM [19408][[INFO] ] Current hostname: xxx 2020-02-27 06:02:07 PM [19408][[INFO] ] Current ip: xxx 2020-02-27 06:02:07 PM [19408][[INFO] ] Current ip hex: xxx 2020-02-27 06:02:07 PM [19408][[DEBUG] ] Get router from server successfully 2020-02-27 06:02:07 PM [19408][[DEBUG] ] Trying connecting to the best server 2020-02-27 06:02:07 PM [19408][[INFO] ] Try connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[WARNING] ] Cannot connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[INFO] ] Try connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[WARNING] ] Cannot connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[INFO] ] Try connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[WARNING] ] Cannot connect to server 127.0.0.1:2280. 2020-02-27 06:02:07 PM [19408][[ERROR] ] Failed to initialize cat: Error occurred while getting router config from remote server. 2020-02-27 06:02:07 PM [19408][[INFO] ] Cat has been initialized with appkey: mip 2020-02-27 06:02:21 PM [19596][[INFO] ] Master process has been forked, heartbeat will be disabled.​

远程配置和本地配置是什么

gfreezy avatar Jun 02 '20 07:06 gfreezy

不清楚您(@gfreezy )说的远程配置和本地配置是啥配置，以下是我的client.xml文件配置 <?xml version="1.0" encoding="utf-8"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="config.xsd"> <servers> <!-- Local mode for development --> <server ip="xxxxxxx.hz" port="2280" http-port="2281" /> <server ip="xxxxxxx.hz" port="2280" http-port="2281" /> </servers> </config>

<server ip="xxxxxxx.hz" port="2280" http-port="2281" /> <server ip="xxxxxxx.hz" port="2280" http-port="2281" />

这里的 IP 设置是正确的吗？

https://github.com/dianping/cat/wiki/global#%E9%85%8D%E7%BD%AE%E7%A4%BA%E4%BE%8B-1

这里我记得好像是不支持 127.0.0.1，必须要配置成网卡IP，并且与 client.xml 一致

gfreezy avatar Jun 02 '20 10:06 gfreezy

@gfreezy 这里的IP设置应该是正确的，因为公司JAVA服务都是用的相同内容的配置文件，只是我这个是Python服务，不是Java服务。但是python的cat-sdk总是会去读127.0.0.1的IP地址；看了一圈加载clent.xml文件的源码，也没发现什么猫腻。 `>>> import cat
