修改软件源

Ubuntu 默认的软件源是境外的，速度上会有些问题，我们可以在「Software & Updates」(软件和更新)中选择国内的镜像。
还可以直接修改配置文件 https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.775b1b11o2W9u7

ssh服务

安装

sudo apt update
sudo apt install openssh-server

ssh免密登录失败

win10产生密钥
Ubuntu 添加密钥到 authorized_keys

修改配置文件：/etc/ssh/sshd_config

 StrictModes no

 PubkeyAuthentication yes

 AuthorizedKeysFile      .ssh/authorized_keys

 PasswordAuthentication yes

 ssh -i ~/.ssh/id_rsa xxx@192.168.1.103

git

安装

sudo apt update
sudo apt install git
sudo apt install cmake

配置

git配置

静态IP

VirtualBox安装完Ubuntu后，默认应该是开启一块网卡，连接方式根据宿主电脑的连接方式来（如果物理机是通过有线上网，那么需要使用NAT网络连接方式，如果是无线网络，那么需要使用桥接方式上网），该网卡负责虚拟机的上网。
查看网卡名字
```
 ifconfig
```

sudo vim /etc/netplan/01-network-manager-all.yaml

 sudo apt install samba samba-common -y

配置内容

 sudo vim /etc/samba/smb.conf

 [wtp]
 comment = wtp
 browseable = yes
 path = /home/wtp
 create mask = 0755
 directory mask = 0755
 valid users = wtp
 force user = wtp
 force group = wtp
 public = yes
 available = yes
 writable = yes

添加用户
```
 sudo smbpasswd -a wtp
```
重启服务
```
 sudo /etc/init.d/smbd restart
```

关闭终端提示音

在终端输入: sudo vim /etc/inputrc
找到 # set bell-style none 这一行，去掉前面的注释符号和空格。
重启终端

docker

安装docker

#1. 安装
# 官方仓库
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

# 国内仓库
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

# Ubuntu 22.04
sudo apt-key list
# 0EBFCD88 是 [ unknown] Docker Release (CE deb) <docker@docker.com> 的 Pub的最后8个字符
sudo apt-key export 0EBFCD88 | sudo gpg --dearmour -o /etc/apt/trusted.gpg.d/slack.gpg

# 安装
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

#2. 修改配置
sudo gedit /etc/docker/daemon.json 为:
{
"registry-mirrors": ["https://xxx.mirror.aliyuncs.com"]
,"insecure-registries": [ "192.168.56.101:6088"]
}

#3.重启docker

sudo service docker restart

#4.将账号权限加入docker组：

sudo groupadd docker #添加docker用户组
sudo gpasswd -a $USER docker #将登陆用户加入到docker用户组中
newgrp docker #更新用户

修改swap分区大小

#1. 查看swap分区大小
free -h
#2. 关闭swap分区
sudo swapoff /swapfile
free -h
#3. 修改swap分区大小到8GB
sudo fallocate -l 12G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
#4. 开启swap分区
sudo swapon /swapfile
#5. 查看swap分区大小
free -h
#6. 删除swap分区
sudo rm /swapfile

修复磁盘错误(Read-only file system)

sudo fsck /dev/sda5 -y
sudo reboot
