# 没有golang网站证书问题的解决办法

#### 问题现象描述

编译TF-Serving时提示“unable to find valid certification path to requested target”，没有golang的证书。详细信息如下：

```
ERROR: /home/cya/boss/tfserving/serving/WORKSPACE:77:10: fetching _go_download_sdk rule //external:go_sdk: Traceback (most recent call last):
        File "/home/cya/boss/tfserving/serving/output/ba6572d0268f10026d9549fa2ae08318/external/io_bazel_rules_go/go/private/sdk.bzl", line 71, column 21, in _go_download_sdk_impl

WARNING: errors encountered while analyzing target '//tensorflow_serving/model_servers:tensorflow_model_server': it will not be built
```


#### 关键过程、根本原因分析

下载依赖组件时，找不到请求目标的有效证书。


#### 结论、解决方案及效果

1. 打开证书信息存储文件“tls-ca-bundle.pem”。
  1 vi /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem

2. 按“i”进入编辑模式，添加如下证书信息。
