centos7.4 64位安裝 google-chrome 與 chromedriver 運行 Python selenium 項目

 centos7.4 實例

 

利用 yum 命令安裝 google-chrome 超級簡單（安裝最新版）：

yum install https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

 

chromedriver 也下載最新版就好，和Mac 版本一樣，我依舊選擇這個最新版本：

http://chromedriver.storage.googleapis.com/index.html?path=70.0.3538.16/

Python3.7 之前安裝過：

Centos7 環境下 Python2.7 換成 Python3.7 運行 scrapy 應用所遇到的問題記錄

 

然后配置一下，就能跑起來 selenium 項目了，當然該 pip install xxx 安裝模塊就缺什么安裝什么了

# 設置 webdriver 參數
        options = webdriver.ChromeOptions()
        # 設置谷歌瀏覽器的一些選項
        #  proxy 代理 options 選項
        options.add_argument(r'--proxy--server=http:\\' + ip)
        uas = get_uas()
        # 設置user-agent
        options.add_argument('user-agent=' + choice(uas))
        # 以 headless 方案運行
        options.add_argument('--headless')
        options.add_argument('--no-sandbox')
        # options.add_argument('--disable-dev-shm-usage')
        # 禁用圖片訪問
        # prefs = {"profile.managed_default_content_settings.images": 2}
        # options.add_experimental_option("prefs", prefs)

 如果不配置  # 以 headless 方案運行

會拋出下面異常

selenium 代碼正確運行：
