Ubuntu wsl的一些坑

wsl中由于权限问题，之前修改了usr目录的权限，导致sudo不能用了，解决方案如下¶

在 windows power shell中

ubuntu1804.exe config --default-user root

chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
chown root /usr/lib/sudo/sudoers.so

ubuntu1804.exe config --default-user hanshuo

windows安装wsl2的教程¶

如何在windows 11中安装WSLG(WSL2) - guojikun - 博客园 (cnblogs.com)

wsl2可视化

export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0

wsl2访问外网：¶

1.首先保证wsl能访问本机ip https://blog.csdn.net/nick_young_qu/article/details/113709768 2.调整socket代理

host_ip=$(cat /etc/resolv.conf |grep "nameserver" |cut -f 2 -d " ")
#export ALL_PROXY="http://$host_ip:10810"
export http_proxy=socks5://$host_ip:10810
export https_proxy=socks5://$host_ip:10810

如果遇到了socket报错，可以暂时先取消代理

unset http_proxy
unset https_proxy

终极大法¶

取消全部代理： unset http_proxy unset HTTP_PROXY unset https_proxy unset HTTPS_PROXY git config --global --unset http.proxy git config --global --unset https.proxy

在windows中C:\Users\hanshuo.wslconfig中覆盖以下内容

[experimental] autoMemoryReclaim=gradual # gradual | dropcache | disabled networkingMode=mirrored dnsTunneling=true firewall=false autoProxy=true
