当我尝试使用Xvfb运行selenium测试时，我得到以下错误

org.openqa.selenium.firefox.NotConnectedException：无法在45000 ms后连接到端口7055上的主机localhost.localdomain . Firefox控制台输出：错误：无法打开显示：1

这些是我使用过的配置

Selenium版本：2.53.0 Firefox版本46

我检查了端口7055它不活动的netstat -ntlp | grep 7055

但是Xvfb正在linux服务器上运行netstat -ntlp | grep Xvfb tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 31384 / Xvfb

我尝试运行Xvfb服务器端口号不能正常工作Xvfb：1 -screen 0 1024x768x16 -nolisten inet6 -port 7055 -from localhost.localdomain

请帮忙

码

public static WebDriver getWebDriver(WebDriverImplementation implementation) {
    switch (implementation) {
        case FIREFOX:

            return new FirefoxDriver(getFirefoxCapabilities());
        case FIREBUG: {
            FirefoxProfile firefoxProfile = new FirefoxProfile();
            String seleniumPath = System.getProperty("selenuim.webdriver.path");
            try {
                firefoxProfile.addExtension(new File(seleniumPath + "/" + FIREBUG_FILENAME));
