xray问题排查,curl: (35) Encountered end of file(已解决)

经过了好几次排查,都没找到问题,先说问题的排查过程,多次确认了user信息,包括用户id和alterid,都没问题,头大的一逼

问题排查过程

确保本地的xray服务是正常的

[root@k8s-master01 xray]# systemctl status xray
● xray.service - Xray Service

从这一步看上去没问题,接着又开始第二步,通过journalctl排查

[root@k8s-master01 xray]# journalctl -f -xu xray

也没看出什么问题,windows上测试几次都是正常的

为了保持统一,已经把windows上的config.json的内容复制粘贴到centos上了

现在开始接下来操作就是配日志(服务端和客户端都配置了)

  "log": {
    "access": "/var/log/xray/access.log",
    "error": "/var/log/xray/error.log",
    "loglevel": "debug"
  },

然后通过tail命令查看

服务端日志是这个

说实话,看了上面两个日志,我是摸不着头,因为userid和alterid都确认过都不知道多少次了,都感觉没问题

一度怀疑是xray的问题,于是换了一个客户端,采用v2ray的客服端

于是用v2ray进行本地服务配置,可还是出现同样的问题

后面网上说通过alter为0可以解决,然后还有其它乱七八着的解决方法,还是不行

终于,看到一条有用的信息,时间差

于是,更新centos的时间

 ntpdate time.windows.com

 再次查看
