最近，我将网格从旧的RHEL7服务器迁移到了新的RHEL8服务器。当我在新机器上运行对接-组合时，节点不会连接到集线器。

docker-compose.yml

version: "3"
services:
  selenium-hub:
    image: selenium/hub:3.141.59-20200525
    container_name: selenium-hub
    ports:
      - "4444:4444"
  chrome:
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
    image: selenium/node-chrome-debug:3.141.59-20200525
    volumes:
      - "/dev/shm:/dev/shm"
  firefox:
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
    image: selenium/node-firefox-debug:3.141.59-20200525
    volumes:
      - "/dev/shm:/dev/shm"

测试命令

$ docker-compose up --scale chrome=1 --scale firefox=0

终端出

注意： RHEL8使用podman，但是它被删除了，所以我们可以继续使用docker-RHEL8。

docker-compose

docker-selenium

rhel8

java

linux

这需要一些时间，但我们已经发现了一个修复方法，并在第二台机器上验证了这些步骤。

安装

IpTables

$ yum install iptables-services
$ systemctl start iptables
$ systemctl enable iptables

配置IpTables以允许集线器的端口

$ sudo iptables -A INPUT -p tcp --dport 4444 -j ACCEPT

关闭了防火墙守护进程

$ systemctl stop firewalld

Start/Restart码头守护进程

$ systemctl restart docker
