作者:小鱼的互联网观察 发布时间:December 13, 2023 分类:互联网观察

错误提示,

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)>

解决办法:

# install_certifi.py## sample script to install or update a set of default Root Certificates# for the ssl module.  Uses the certificates provided by the certifi package:#       https://pypi.python.org/pypi/certifiimport osimport os.pathimport sslimport statimport subprocessimport sysSTAT_0o775 = ( stat.S_IRUSR | stat.S_IWUSR | stat.S_IXUSR             | stat.S_IRGRP | stat.S_IWGRP | stat.S_IXGRP             | stat.S_IROTH |                stat.S_IXOTH )def main():    openssl_dir, openssl_cafile = os.path.split(        ssl.get_default_verify_paths().openssl_cafile)    print(" -- pip install --upgrade certifi")    subprocess.check_call([sys.executable,        "-E", "-s", "-m", "pip", "install", "--upgrade", "certifi"])    import certifi    # change working directory to the default SSL directory    os.chdir(openssl_dir)    relpath_to_certifi_cafile = os.path.relpath(certifi.where())    print(" -- removing any existing file or link")    try:        os.remove(openssl_cafile)    except FileNotFoundError:        pass    print(" -- creating symlink to certifi certificate bundle")    os.symlink(relpath_to_certifi_cafile, openssl_cafile)    print(" -- setting permissions")    os.chmod(openssl_cafile, STAT_0o775)    print(" -- update complete")if __name__ == '__main__':    main()

PVE8开启IOMMU硬件直通功能

作者:小鱼的互联网观察 发布时间:December 6, 2023 分类:linux

1、进入SHELL命令窗口下

~# nano /etc/default/grub


修改行“GRUB_CMDLINE_LINUX_DEFAULT="quiet",

使其为“GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on",


如果是amd cpu请改为:GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on" 。


2、更新grud

~# update-grub

Generating grub configuration file ...

Found linux image: /boot/vmlinuz-6.2.16-3-pve

Found initrd image: /boot/initrd.img-6.2.16-3-pve

Found memtest86+x64 image: /boot/memtest86+x64.bin

done



3、新增模块。修改文件/etc/modules,加入如下的行


~# nano /etc/modules


vfio

vfio_iommu_type1

vfio_pci

vfio_virqfd

 

4、重启系统

~#reboot

5、可以在PVE WEB界面添加需要直通的PCI设备了。
