apache - 502 Bad Gateway nginx/1.11.5 在 docker 中运行

转载作者：行者123 更新时间：2023-12-02 18:07:45

我在 Apache Karaf 中运行 soap Web 服务，我们使用的是 Apache CXF 2.7.6，JDK 是 1.7.0_80。我在 Centos 7 下的 Oracle VM Virtual box 上的笔记本电脑上的 docker 容器中运行以下命令

MongoDB
ActiveMQ
BlazeDS
HTTPD
OpenLDAP
NGINX
关系

Apache Flex 中的 UI 调用以下 url 进行登录，我们收到以下错误:

http://my_virtual_machine_ip_address/usermanagementcxf/UserManagementService?wsdl结果从 Nginx 进入 502 Bad Gateway

在这里，请注意 Nginx 在 docker 内部运行，而托管 soap 服务的 Apache Karaf 不是在 docker 内部而是在 docker 外部运行，基本上是在本地运行。

能否请您告诉我在这里可以做些什么来解决这个问题？非常感谢这方面的任何帮助。

我还尝试了以下方法来解决这个问题:

重启 Nginx、httpd 和 blazeds
setsebool -P httpd_can_network_connect true
setsebool -P httpd_can_network_relay 1
重启 Centos 7 操作系统

最佳答案

以下对我有用。如果您正在使用由 docker 创建并命名为 docker0 的以太网桥，您可以通过以 root 身份运行以下命令来设置以下转发规则:

iptables -A FORWARD -i docker0 -o eth0 -j ACCEPT
iptables -A FORWARD -i eth0 -o docker0 -j ACCEPT
iptables -I 输入 1 -i docker0 -j 接受
iptables-保存
reboot命令重启机器
