# Linux环境配置

## 系统配置

### 代理设置

# 设置代理（通过宿主机）
export http_proxy="http://192.168.31.14:7890"
export https_proxy=$http_proxy

# 取消代理
unset http_proxy
unset https_proxy

**提示：** 可将代理配置添加到 `~/.bashrc` 或 `~/.zshrc` 以永久生效。

### APT 软件源

- 镜像源
- [阿里巴巴开源镜像](https://developer.aliyun.com/mirror/)

# 备份原有源
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

# 写入阿里云镜像源
# 适用于 **Ubuntu 22.04 (Jammy)**
sudo bash -c 'cat << EOF > /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
EOF'

# 更新软件源
sudo apt update && sudo apt upgrade -y

### 时区配置

# 交互式选择时区
sudo tzselect

# 设置为上海时区
sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

# 或使用 timedatectl（推荐）
sudo timedatectl set-timezone Asia/Shanghai

## 软件

### Samba

# 1. 安装 Samba
sudo apt install samba samba-common -y

# 2. 编辑配置文件
sudo vim /etc/samba/smb.conf

在文件末尾添加：

[share]
comment = Share Folder
browseable = yes
path = /home/share  # 建议使用具体路径而非根目录
create mask = 0755
directory mask = 0755
valid users = your_username  # 指定允许访问的用户
writable = yes

# 3. 创建共享目录
sudo mkdir -p /home/share
sudo chmod 755 /home/share

# 4. 添加 Samba 用户
sudo smbpasswd -a your_username

# 5. 重启服务
sudo systemctl restart smbd
sudo systemctl enable smbd  # 开机自启

**安全建议：**
- 避免共享根目录 `/`
- 使用 `valid users` 限制访问
- 设置合理的权限掩码

## FAQ

### 修复 sudo 权限问题

当普通用户无法使用 sudo 时：

# 1. 切换到 root
su root

# 2. 编辑 sudoers 文件
visudo

# 3. 添加以下行（替换 username 为实际用户名）
username ALL=(ALL:ALL) ALL

# 或者将用户添加到 sudo 组
usermod -aG sudo username

**注意：** 使用 `visudo` 而非直接编辑 `/etc/sudoers`，可防止语法错误导致系统问题。
