在 Mac M1 上安装 selenium

自从主力机换成 M1 后，就很少开docker了，很多容器都没有做arm架构的镜像。我常用的 selenium 也是，可叹。最后还是裸着安装了。以前在这篇文章里折腾过本地安装《selenium 裸安装备忘》，这次也是类似的操作，在本篇文章里记录一下。

一、安装java

brew install java

export PATH="/opt/homebrew/opt/openjdk/bin:$PATH"
alias java="/opt/homebrew/opt/openjdk/bin/java

我发现 Mac 下的PATH有问题，在 zshrc 里改的不符合想法，系统的PATH还是在前面，我担心这样会有问题，遂直接改了这个文件 /etc/paths。

二、安装chromedriver

先去官网下载 Chrome 版本对应的Chromedriver：https://chromedriver.chromium.org/downloads，扔到 path 对应的目录里。这里我扔到 ~/bin 目录下

Mac 下允许执行权限，设置->安全 里：

三、安装selenium

官方地址：https://www.selenium.dev/downloads/

我下载了目前最新的 4.6.0版本：

然后运行：

java -jar bin/selenium-server-4.6.0.jar standalone --host 100.100.100.9 --port 14444

IP 端口根据各自的需要配置了。

看到日志显示找到driver 就说明已经运行成功了。

尝试调用，看到输出了：

四、番外-容器化

这两个命令是可以跑起来了：

docker run -d -p 4444:4444 --name selenium-hub selenium/hub:latest 
docker run -d --link selenium-hub:hub -e SE_EVENT_BUS_HOST=hub -e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 -e SE_EVENT_BUS_PUBLISH_PORT=4442 -p 5900:5900 --name selenium-node-chrome-vnc selenium/node-chrome:latest 

因为 arm下还没有相关的镜像，虽然容器可以运行

但是无法拉起chrome，用代码拉起chrome一定报错

其实如果直接在vnc里启动chrome，也可以注意到，chrome是无法启动的：

正常情况下应该是这个样子：

所以如果有需要远程运行的话，找一台x86的机器运行即可。我也是没想到，我x86的MacBook Air还能发挥余热。

docker run -d \
  --name selenium-chrome-1 \
  --restart always \
  --network bridge \
  -p 5901:5900 \
  -p 4445:4444 \
  -v /dev/shm:/dev/shm \
  selenium/standalone-chrome-debug

docker run -d \
  --name selenium-chrome-2 \
  --restart always \
  --network bridge \
  -p 5902:5900 \
  -p 4446:4444 \
  -v /dev/shm:/dev/shm \

docker run -d \
  --name selenium-chrome-3 \
  --restart always \
  --network bridge \
  -p 5903:5900 \
  -p 4447:4444 \
