Ubuntu 配置

1.更改源

源备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

源更改

sudo vim /etc/apt/sources.list

清华源地址： Go.

# 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://mirrors6.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors6.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors6.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors6.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse

2.使用ipv6

安装miredo

1. sudo apt-get install miredo
2. 以root权限打开ufw的配置文件: “/etc/default/ufw”，找到"IPV6=no"这一行，将其改为"IPV6=yes"。
3. sudo invoke-rc.d networking restart

ubuntu16.04按照上述方案，ipv6地址出来了，但是仍不能访问ipv6网址。

• 原因
  当前用的是校园网动态分配的ipv6地址，需要改成静态的。
• 方法
  1.只需要改变/etc/sysctl.d/10-ipv6-privacy.conf文件，将net.ipv6.conf.default.use_tempaddr改为0
  2.sudo sysctl --system #加载所有的配置文件

测试：

ping6 ipv6.baidu.com

3.安装SSH

1.查看ssh是否安装

sudo ps -e |grep ssh

2.安装ssh

sudo apt-get install openssh-server

4.tab不能补全

1：打开终端输入如下命令：

sudo vim /etc/bash.bashrc

2：将下面代码注释取消

# enable bash completion in interactive shells  
#if ! shopt -oq posix; then  
# if [ -f /usr/share/bash-completion/bash_completion ]; then  
#    . /usr/share/bash-completion/bash_completion  
#  elif [ -f /etc/bash_completion ]; then  
#    . /etc/bash_completion  
#  fi  
#fi

3：重启ubuntu

sudo reboot
