无法打开/proc/net/unix:没有这样的文件或目录// invoke-rc.d:无法确定当前的运行级别
我正试图在我的wsl Ubuntu 18.04上重新安装mysql服务器。
(我在Windows 10上有MySQL服务器，但在端口3307上。如果这很重要，那就去看看吧，以防万一！)
我不能sudo service mysql start和sudo /etc/init.d/mysql start，它又回来了
No directory, logging in with HOME=/
mkdir: cannot create directory ‘//.cache’: Permission denied
-su: 19: /etc/profile.d/wsl-integration.sh: cannot create //.cache/wslu/integration: Directory nonexistent [Failed]我在谷歌上搜索了有关在Ubuntu中重新安装mysql的信息，并遵循了以下步骤。
sudo su
apt-get remove --purge 'mysql*'
apt-get autoremove
apt-get autoclean
rm -f /etc/mysql /var/lib/mysql
apt-get install mysql-server但是在尝试apt-get install mysql-server时，我得到了下面的错误。
invoke-rc.d: could not determine current runlevel
* Stopping MySQL database server mysqld [ OK ]
update-alternatives: using /etc/mysql/mysql.cnf to provide /etc/mysql/my.cnf (my.cnf) in auto mode
Renaming removed key_buffer and myisam-recover options (if present)

Package mysql-server-5.7 is not configured yet.我一直在谷歌Cannot open /proc/net/unix: No such file or directory和invoke-rc.d: could not determine current runlevel问题，但没有找到正确的解决方案。
如果你能就此给我一些建议，我真的很感激。谢谢!

当我查看日志文件/var/log/mysql/error.log时，我发现
[ERROR] [MY-012585] [InnoDB] Linux Native AIO interface is not supported on this platform. Please check your OS documentation and install appropriate binary of InnoDB.通过创建一个新的配置文件/etc/mysql/conf.d/no_native_aio.conf，我禁用了本机AIO的使用
[mysqld]
innodb_use_native_aio = 0 然后，我能够像这样启动数据库服务器：
sudo service mysql start我还得跑
sudo mysql_secure_installation若要设置根用户的密码，请执行以下操作。
我不得不欺骗dpkg，让它相信postinstall脚本已经成功运行了：
/var/lib/dpkg/info/mysql-server-8.0.postinst
- running
sudo dpkg --configure -a
- removing中的
- 添加
exit 0作为第二行--/var/lib/dpkg/info/mysql-server-8.0.postinst
中的exit 0

这将是一个WSL1与WSL2的问题。/proc目录没有完全填充WSL1。要检查您的版本运行(从powershell) wsl -l -v。如果它没有提供任何版本信息，那么您就在WSL1上了。
