CentOS8
出现了。CentOS8
https://wiki.centos.org/zh/Manuals/ReleaseNotes/CentOS8.1905
在创建GCE时，我在选择操作系统时看到了发布选项。
因此，我打算暂时启动它来测试一下。

我会省略细节。
启动盘选择
机器配置

CentOS7与之前版本的区别
我已在以下网站上确认了变更点。
需要注意的是 CentOS 8 和 CentOS 7 的差异，以及 yum 和中间件。
yum命令已被替换为dnf命令。
CentOS7 的一种选择。
/bin/yum 可以在操作系统中使用命令行进行包管理操作。
#!/usr/bin/python
import sys
try:
import yum
except ImportError:
print >> sys.stderr, """\
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
%s
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
%s
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
""" % (sys.exc_value, sys.version)
sys.exit(1)
sys.path.insert(0, '/usr/share/yum-cli')
try:
import yummain
yummain.user_main(sys.argv[1:], exit_code=True)
except KeyboardInterrupt, e:
print >> sys.stderr, "\n\nExiting on user cancel."
sys.exit(1)

最终
・非常高频地使用PHP/Mysql等软件进行升级让我感到很高兴。
・不知道性能是否有所改变，我打算以后验证一下。
