1.安装浏览器

指定yum 源

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

安装

curl https://intoli.com/install-google-chrome.sh | bash

ldd /opt/google/chrome/chrome | grep "not found"

安装后,执行:

google-chrome-stable --no-sandbox --headless --disable-gpu --screenshot https://www.baidu.com/

成功之后会生成一个图片

查看 版本 很重要

google-chrome --version

#Google Chrome 78.0.3904.108  
#所以下载我们也只能下载对应的版本

2. 安装chromedriver

下载:https://npm.taobao.org/mirrors/chromedriver/ 索引 挑选自己系统匹配的

wget https://npm.taobao.org/mirrors/chromedriver/78.0.3904.11/chromedriver_linux64.zip

unzip 解压

unzip chromedriver_linux64.zip

./chromedriver

Starting ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945@{#614}) on port 9515
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
[1575091012.429][SEVERE]: bind() failed: Cannot assign requested address (99)

如果出现了 Cannot assign requested address (99)

#执行命令修改如下内核参数 (需要root权限) 
#调低端口释放后的等待时间,默认为60s,修改为15~30s:

sysctl -w net.ipv4.tcp_fin_timeout=30

#修改tcp/ip协议配置, 通过配置/proc/sys/net/ipv4/tcp_tw_resue, 默认为0,修改为1,释放TIME_WAIT端口给新连接使用:

sysctl -w net.ipv4.tcp_timestamps=1

#修改tcp/ip协议配置,快速回收socket资源,默认为0,修改为1:

sysctl -w net.ipv4.tcp_tw_recycle=1

#允许端口重用:

sysctl -w net.ipv4.tcp_tw_reuse = 1

安装完成
 建立软连接:

ln -s /root/data/soft/chromedriver /usr/bin/chromedriver

3. 测试代码

#coding=utf8
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
driver = webdriver.Chrome(chrome_options=chrome_options)
#driver = webdriver.Chrome()
driver.get("https://www.baidu.com")

print(driver.page_source)
#driver.quit()
