在CentOS7上设置Selenium [英] Set up Selenium on CentOS7
问题描述
我正在尝试在CentOS-VM上设置测试环境。
I am trying to set up test environment on my CentOS-VM.
我在Eclipse中运行的Java-maven-project中有以下三个文件：
I have the following three files in my Java-maven-project running in Eclipse:
main.java
package main;
public class main {
public static void main(String[] args) {
StartFirefox fire = new StartFirefox();
StartChrome chrome = new StartChrome();
chrome.start();
fire.start();
}
}
启动Firefox.java
package main;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class StartFirefox {
WebDriver fire;
public StartFirefox() {
System.setProperty("webdriver.gecko.driver", "src/main/resources/geckodriver/geckodriver");
System.out.println("debug 1");
fire = new FirefoxDriver();
System.out.println("debug 2");
fire.manage().window().maximize();
}
public void start() {
System.out.println("debug 3");
fire.get("https://www.google.com/");
System.out.println("debug 4");
}
}
StartChrome.java
package main;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class StartChrome {
WebDriver chrome;
public StartChrome() {
String pathToChromeDriver = "src/main/resources/chromedriver/chromedriver";
System.setProperty("webdriver.chrome.driver", pathToChromeDriver);
System.out.println("debug 1");
chrome = new ChromeDriver();
System.out.println("debug 2");
}
public void start() {
System.out.println("debug 3");
chrome.get("https://www.google.com/");
System.out.println("debug 4");
}
}
使用Firefox运行程序时，窗口打开，但不会转到我的网址。
相反，一段时间后（似乎是超时），我在控制台中得到以下输出：
When running the program with Firefox the window opens, but it doesn't go to my url. Instead I get the following output in the console after some time (seems to be a timeout):

我是卡在这里，因为我不知道如何解决此问题。可能是什么原因？
I am stuck here as I don't know how to fix this problem. What may be the cause?

何时在Windows 10上运行此项目，一切正常。
When running this project on Windows 10 it all works fine.
所以操作系统似乎有问题。但是搜索时找不到任何解决方案。它只说了有关服务器和无头版本的内容。
So it seems to be a problem with the OS. But I can't find any solutions when searching. It only says something about a server and headless version.
更新：
添加了调试消息。 Firefox仅到达消息1，而Chrome直到消息3才打印。
Added debug messages. Firefox reaches only message 1, while Chrome prints until message 3.
推荐答案
您从geckodriver 0.19.1开始的第一个错误堆栈跟踪给我们一些提示：
Your first error stack trace from the geckodriver 0.19.1 does gives us some hint:
org.openqa.selenium.WebDriverException：连接被拒绝
org.openqa.selenium.WebDriverException: connection refused
但是来自ChromeDriver（v2.9.248304）的第二个堆栈跟踪说明了一切：
But the second stack trace from ChromeDriver (v2.9.248304) says it all:
org。 openqa.selenium.WebDriverException：org.apache.http.conn.HttpHostConnectException：连接到localhost：8004 [localhost / 127.0.0.1，localhost / 0：0：0：0：0：0：0：0：1]失败：连接被拒绝（拒绝连接）
org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:8004 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused (Connection refused)
/ etc / hosts文件中的条目未正确配置。
The entries within the /etc/hosts file are not properly configured.
要解决此问题，请确保Linux Box上的 / etc / hosts 包含以下条目：
To fix this, ensure that /etc/hosts on your Linux Box contains the following entry:
127.0.0.1 localhost.localdomain localhost
