所以我最终想在 AWS 上设置一个经典的负载均衡器，并且我有一个带有 2 个公共子网的 VPC，但是现在我不确定我是否可以将这两个子网用于那个 EC2 实例，还是需要两个 ec2 实例？
所以我发现自己被迫使用 Windows 机器只是因为金融机构认为这对外部承包商来说更安全。
我正在使用 powershell，我刚刚svg从他们的内部设计师那里收到了一些资产，我将这些资产提交并推送到我正在工作的分支中，然后在出现此错误时尝试合并到另一个分支：
error: cannot stat 'media/images1': Permission denied
现在我什至无法签出我开始这项工作的另一个分支，我什至无法 cd查看这些文件具有media/images1什么样的权限。svg
所以我想知道是否有人可以指导我如何在你拒绝某人运行 a 的能力的情况下完成这项工作git pull，cd或者甚至git checkout <other-branches>只是因为你没有这些文件的权限？
更好的是，我通常会要求谁在公司中纠正这个问题？做这件事通常是谁的工作？
我有从浏览器到 Express API 或我的反应服务器的 Nginx 路由请求，但是，在控制台中，我继续收到刚刚挂起的 xhr 请求，然后超时并出现 502 bad gateway 错误，这通常是由于 Nginx 无法将请求传递给“上游”，在这种情况下是我的 Express API，通常我可以检查/var/log/nginx/文件，但是当所有这些都发生在 Docker 容器中时，我不确定如何做到这一点。
我已经尝试过这种docker logs <container name/id>命令方法，但我得到了Error: No such container: <container-id>.
我在运行后从最后一行获取了容器 ID docker-compose up --build，它说Successfully built <container-id>
我复制了那个 id 并docker logs <container-id>在我的 iTerm 的第二个面板上运行。
然后我做了一个docker ps并得到了这个输出：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f37be54a9e60 complexly_api "npm run dev" 43 minutes ago Up 28 minutes complexly_api_1

我相信我需要获取其中一个容器 ID 并docker logs使用，但我不确定。
在我的站点中，执行以下配置后，我得到一个 502 bad gateway：

我做了一个：
sudo tail -30 /var/log/nginx/error.log
并收到以下错误，但我不知道它们是什么意思：
PHP message: PHP Notice: Undefined index: success in /var/www/microurb.com/public_html/index.php on line 295" while reading upstream, client: 24.55.9.54, server: www.microurb.club, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "www.microurb.club"

我相信问题根源于我上面的配置，但我不确定在哪里。当我尝试取消注释此块时：
31 # location / {
32 # # First attempt to serve request as file, then
33 # # as directory, then fall back to displaying a 404.
34 # try_files $uri $uri/ =404;
35 # }
运行后我得到一个错误，sudo nginx -t说我有nginx: [emerg] duplicate location "/" in /etc/nginx/sites-enabled/microurb.com:31，但我只有一个。不知道为什么我会收到那个错误。
我正在尝试登录到 centos 6.8 服务器，并且我有 IP 地址和正确的密码。它将私钥存储在我的 known_hosts 文件中，但后来我忘记了。我的同事可以从他的计算机登录，他在发送给我的 id_rsa.pub 文件中拥有私钥。当我存储它时，我仍然无法登录。我删除了那个文件，但我仍然无法登录，我无法理解下面的这个错误日志，请帮助。
