memsql_platform.network.state.primary_state.primary_poll: 查找本地代理失败

Question

我正在尝试按照说明在离线模式下在 RHEL 6 机器上安装 MemSQL 4.1.7： http://docs.memsql.com/latest/setup/offline/

在第 3 步中，memsql-ops 启动命令完成并出现以下错误消息

    memsql-ops-4.1.7 > memsql-ops/memsql-ops start
    Starting MemSQL Ops...
    Exception in thread Thread-7:
    Traceback (most recent call last):
    File "/usr/local/updated-openssl/lib/python3.4/threading.py", line 921, in _bootstrap_inner
    File "/usr/local/updated-openssl/lib/python3.4/threading.py", line 869, in run
    File "/memsql_platform/memsql_platform/agent/daemon/manage.py", line 198, in startup_watcher

    File "/usr/local/updated-openssl/lib/python3.4/site-packages/simplejson/decoder.py", line 400, in raw_decode
simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

之后我可以访问 MemSQL Ops Web 界面，它会提示 "MemSQL Ops is unable to connect to the MemSQL download servers" 并提示我添加二进制文件。因此我按照说明指南的第 5 步进行操作并得到了这个错误

    memsql-ops > memsql-ops file-add -t memsql memsqlbin_amd64.tar.gz
    Traceback (most recent call last):

任何人都可以确认 MemSQL 4.1.7 是否适用于 RHEL 6 或者它是否需要一些其他依赖项？

Answer 1

正如@Wayne Song 在评论中指出的那样。 MemSQL Ops 命令行通过向 127.0.0.1:9000

发送 API 请求来工作

因此，如果您的服务器位于公司防火墙内，则可能无法通过对 127.0.0.1 的请求。所以将 127.0.0.1 添加到 no_proxy 解决了这个问题。

您可以在命令行中将其设置为：

export no_proxy=127.0.0.1
