linux centos安裝google chrome瀏覽器使用headless無(wú)頭模式

用java開(kāi)發(fā)爬蟲(chóng)，或者需要java操作控制瀏覽器來(lái)渲染頁(yè)面，抓取頁(yè)面元素，都需要在linux安裝google chrome瀏覽器，然后就可以通過(guò)chrome driver來(lái)連接操作chrome瀏覽器了，下面就介紹linux centos安裝google chrome瀏覽器.

1.linux centos7安裝 google chrome

下載google瀏覽器并安裝

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
sudo yum install google-chrome-stable_current_*.rpm

一般這樣是下載不到的，需要墻，你就只能墻后下載好了再上傳再安裝。

2.測(cè)試運(yùn)行g(shù)oogle chrome

# google-chrome --version
[14479:14479:0222/121214.627009:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

報(bào)錯(cuò)了

是因?yàn)椋荒苁褂胷oot用戶(hù)運(yùn)行沙盒模式，

解決方法是新建用戶(hù)再測(cè)試，linux新建用戶(hù)參考：linux 添加用戶(hù) 并添加文件權(quán)限

然后再測(cè)試

[test@localhost root]$ google-chrome --version
Google Chrome 80.0.3987.116 

3.linux 運(yùn)行g(shù)oogle chrome瀏覽器headless無(wú)頭模式

用headless模式打印網(wǎng)頁(yè)pdf,注意要有運(yùn)行輸出文件夾的權(quán)限

google-chrome --headless --disable-gpu --print-to-pdf http://www.baidu.com

google-chrome --headless --disable-gpu --no-sandbox --print-to-pdf http://www.baidu.com

系統(tǒng)中文亂碼

https://www.cnblogs.com/vekair/p/15878518.html

安裝中文系統(tǒng)支持，執(zhí)行下面三個(gè)命令就可以解決：
yum -y groupinstall "X Window System"
yum -y groupinstall chinese-support
yum -y groupinstall Fonts
我只成功執(zhí)行了第一個(gè)和第三個(gè) 問(wèn)題也解決了

安裝jdk

上傳jdk-8u144-linux-x64.tar.gz
將本地下載的jdk上傳到 /home/work/java 目錄下

[root@iZ4zeaehxxqhrn553tblkkZ /]# cd /home/work/java
[root@iZ4zeaehxxqhrn553tblkkZ /]# rz 

解壓

[root@iZ4zeaehxxqhrn553tblkkZ /]# cd /home/work/java
[root@iZ4zeaehxxqhrn553tblkkZ /]# tar -zxvf jdk-8u144-linux-x64.tar.gz

配置環(huán)境變量
在/etc/profile文件的末尾加上以下配置:

[root@iZ4zeaehxxqhrn553tblkkZ /]# vim /etc/profile

末尾增加如下內(nèi)容：

JAVA_HOME=/home/work/java/jdk1.8.0_144
JRE_HOME=/home/work/java/jdk1.8.0_144/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH

profile文件立即生效文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-486823.html

[root@iZ4zeaehxxqhrn553tblkkZ /]# source /etc/profile

錯(cuò)誤信息記錄：

Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.4.0-31-generic x86_64)

解決辦法：

  chromeOptions.addArguments("--no-sandbox","--disable-dev-shm-usage","window-size=1920x3000","--disable-gpu","--hide-scrollbars","blink-settings=imagesEnabled=false","--headless");

示例代碼：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/timbl/goole")
public class GooleController
{
    /**
     * 獲取參數(shù)配置列表
     */
    @GetMapping("/list")
    public Object list()
    {
        //命令啟動(dòng)瀏覽器
        String os = System.getProperty("os.name");
        String drivePath = "D:\\Desktop\\工具demo\\goole\\chromedriver.exe";
        if (os.toLowerCase().startsWith("windows")) {
        } else if (os.toLowerCase().startsWith("linux")) {
            drivePath = "/usr/bin/chromedriver";
        }
        System.out.println(drivePath);
        System.setProperty("webdriver.chrome.driver", drivePath);
        //創(chuàng)建無(wú)Chrome無(wú)頭參數(shù)
        ChromeOptions chromeOptions=new ChromeOptions();
        chromeOptions.setHeadless(Boolean.TRUE);
   
		// 
        chromeOptions.addArguments("--no-sandbox","--disable-dev-shm-usage","window-size=1920x3000","--disable-gpu","--hide-scrollbars","blink-settings=imagesEnabled=false","--headless");
        System.out.println("--------------------------------");
        WebDriver driver = new ChromeDriver(chromeOptions);

        driver.get("http://www.baidu.com");
        String title = driver.getTitle();
        System.out.println(title+"--------------------------------");
        driver.close();
        return "success";
    }

}
