# 配置我的Ubuntu

### 换源

Ubuntu 的软件源配置文件是 `/etc/apt/sources.list`。将系统自带的该文件做个备份，将该文件替换为下面内容，即可使用 TUNA 的软件源镜像。

```
# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
```

最后，输入

```
sudo apt-get update
```



### vim

```
sudo apt install vim
```

### git

安装

```
sudo apt-get install git
```

配置git全局环境

```
git config --global user.name "用户名"
git config --global user.email "邮箱地址"
```

生成密钥

```
ssh-keygen -C 'you email address@gmail.com' -t rsa
```

上传密钥

```
cd ~/.ssh
cat id_rsa.pub
```

### oh-my-zsh

先安装zsh

```
sudo apt-get install zsh
```

安装配置oh-my-zsh

```
wget https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh
chmod +x install.sh
```

```
vim install.sh
```

找到以下部分

```
# Default settings
ZSH=${ZSH:-~/.oh-my-zsh}
REPO=${REPO:-ohmyzsh/ohmyzsh}
REMOTE=${REMOTE:-https://github.com/${REPO}.git}
BRANCH=${BRANCH:-master}
```

把其中两行改为

```
REPO=${REPO:-mirrors/oh-my-zsh}
REMOTE=${REMOTE:-https://gitee.com/${REPO}.git}
```

### net-tools

```
sudo apt-get install net-tools
```

### ssh

安装并启动

```
sudo apt-get install openssh-server
sudo service ssh start
```

更改ssh服务配置

```
vim /etc/ssh/sshd_config
```

把配置文件中的`PermitRootLogin without-password`注释掉
增加一句`PermitRootLogin yes`

确定存在：
`PubkeyAuthentication yes`
`AuthorizedKeysFile .ssh/authorized_keys .ssh/authorized_keys2`

然后插入公钥

```
.ssh
cat id_rsa.pub >> authorized_keys
```

重启ssh服务

```
/etc/init.d/ssh restart
```

**注意** 如果在家里，就使用桥接模式，如果是在学校，桥接模式是不能上网的，只能用NAT模式。

而这时，需要在虚拟机网络配置里选端口转发，添加ip

### GOLANG

先查看最新版Go语言的版本(2021.9.18 时 `go1.17.1`)

```
wget https://golang.google.cn/dl/go1.17.1.linux-amd64.tar.gz
```

将下载好的文件解压到`/usr/local`目录下：

```
sudo tar -zxvf go1.17.1.linux-amd64.tar.gz -C /usr/local
```

配置环境变量

```
sudo vim /etc/profile
```

添加如下代码

```
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
```

然后重启

==不知为何==，在zsh里也要配置上面的变量，否则ssh连接后就识别不到环境变量

```
sudo vim ~/.zshrc
```

加入下面两行代码

```
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
```

修改Goproxy

```
go env -w GOPROXY=https://goproxy.cn,direct
```

### gin框架

```
go get -u github.com/gin-gonic/gin
```

## Mysql

```
sudo apt-get update  #更新源
sudo apt-get install mysql-server #安装
```

验证mysql是否安装上

```
systemctl status mysql
```

然后，我们要修改mysql的认证方式

进入Mysql

```
sudo mysql -u root -p
```

```
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root的密码';
```

### gorm

```
go get -u github.com/jinzhu/gorm
```



### 配置虚拟机的web服务

打开虚拟机网络设置，如果是桥接模式则可以忽略这一步。如果是NAT模式，则需要选择端口转发，主机ip选择虚拟机的ip，子系统ip就是web服务器的ip。
