Centos7minimal安装playwright和firefox、chromium，终于跑起来了

系统环境为CentOS Linux release 7.9.2009 (Core) 最小安装，考虑到playwright的安装需要python3.7+，本次直接选择安装python3.10。Centos7 Python3.10安装部署 之后就开始一波三折的折腾了，最终完成并运行了脚本，模拟浏览器。

1、python3.10安装成功后，就可直接安装playwright

pip3 install playwright -i https://pypi.tuna.tsinghua.edu.cn/simple

2、python3 -m playwright install 将安装模拟的浏览器，firefox、chromium，但在这一步在centos7下会有大量缺少的依赖文件。

解决第一次报错

解决过程

yum install -y centos-release-scl
yum install -y devtoolset-8-gcc*
mv /usr/bin/gcc /usr/bin/gcc-old
ln -s /opt/rh/devtoolset-8/root/bin/gcc /usr/bin/gcc
mv /usr/bin/g++ /usr/bin/g++-old
ln -s /opt/rh/devtoolset-8/root/bin/g++ /usr/bin/g++


wget http://ftp.gnu.org/gnu/make/make-4.3.tar.gz
tar -xzvf make-4.3.tar.gz && cd make-4.3/
./configure  --prefix=/usr/local/make
make && make install
cd /usr/bin/ && mv make make.old
ln -sv /usr/local/make/bin/make /usr/bin/make


yum install -y bison

wget http://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
tar xf glibc-2.28.tar.gz 
cd glibc-2.28/ && mkdir build  && cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin



Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
  Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
  Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are wrong,
  libm.so should point to the newly installed glibc file - and there should be
  only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!

出现这个，算完成。

解决第二次报错

python3 -m playwright install 成功运行

3、运行脚本时还有报错

解决

yum install libXcomposite
yum install libXtst
yum install gtk3

完成！

注意，因为使用的centos系统是没有GUI界面的，所以python脚本一定要设置不显示浏览器，隐藏运行。

browser = await p.firefox.launch(headless=True, )
