CentOS7 Docker安装及网络环境配置含Seleniumdocker使用

本文主要是介绍CentOS7 Docker安装及网络环境配置含Seleniumdocker使用，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

Centos7安装

网络环境准备

----------------------------------------------------------------------------------------------------

//更新DNS，防止DNS解析有问题，更换阿里公共DNS sevver

vi /etc/resolv.conf

增加nameserver 223.5.5.5

保存后，锁住文件防止重启被更新掉

chattr +i /etc/resolv.conf 

reboot

更换yum镜像源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum clean all

yum makecache

---------------------------------------------------------------------------------------------

卸载旧版本 yum -y remove docker docker-common docker-selinux docker-engine

1、yum install -y yum-utils

2、yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3、yum-config-manager --enable docker-ce-nightly

4、yum-config-manager --enable docker-ce-test

5、yum install docker-ce docker-ce-cli containerd.io

6、systemctl start docker

#配置阿里云加速器，https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors 登录进去镜像工具-->镜像加速器-->复制加速地址替换下面的

mkdir -p /etc/docker

vi /etc/docker/daemon.json

{

"registry-mirrors": ["https://pcocmgfc.mirror.aliyuncs.com"]

}

systemctl daemon-reload

systemctl restart docker

docker selenium chrome

docker pull selenium/hub

docker pull selenium/node-chrome

后台启动主hub后台运行容器4444转到宿主机8888

docker run -d -p 8888:4444 --name selenium-hub selenium/hub

启动分支node chrome 容器

docker run -d --link selenium-hub:hub selenium/node-chrome

启动后查看容器id 通过id查看log，log中会有chrome的驱动版本，以及selenium的版本

查看log 命令 docker logs -t 容器id

自己代码只要selenium的版本对应查到的版本即可

注每次docker run会产生对应的容器实例，如果宿主机被重启，可以先删除之前的实例容器id

先启动docker systemctl restart docker

强制删除实例化的容器 docker rm -f $(docker ps -aq)

然后再启动主从

后台启动主hub后台运行容器4444转到宿主机8888

docker run -d -p 8888:4444 --name selenium-hub selenium/hub

启动分支node chrome 容器

docker run -d --link selenium-hub:hub selenium/node-chrome

public static void main(String[] args){

try{

//第一个参数：表示服务器的地址。第二个参数：表示预期的执行对象，其他的浏览器都可以以此类推，ip和端口对应宿主机的ip和容器转发宿主机的端口

WebDriver driver = new RemoteWebDriver(new URL("http://192.168.88.129:8888/wd/hub/"), DesiredCapabilities.chrome());

driver.manage().window().maximize();

driver.get("http://www.baidu.com");

Thread.sleep(2000);

System.out.println("Title----"+driver.getTitle());

Thread.sleep(2000);

driver.quit();

}catch(Exception e){

e.printStackTrace();

}

}
