ubuntu18.04使用记录

1.设置静态IP

//编辑文件
root@ubuntu18:~# cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
    ethernets:
       enp0s5:        #⚠️这里要看一下网卡的名称
           dhcp4: false
           addresses: [10.0.0.15/24]
           gateway4: 10.0.0.1
           nameservers:
                 addresses: [223.5.5.5,114.114.114.114]
    version: 2
    renderer: networkd

//使设置生效
netplan apply

2.开启ssh服务

//ubuntu-18.04desktpo版默认只安装ssh-agent
sudo apt -y install openssh-server

//启动服务
sudo service ssh start

3.安装python3.6

//ubuntu18.04默认python版本是3.7
root@ubuntu18:~# python3
Python 3.7.5rc1 (default, Oct  8 2019, 16:47:45) 
[GCC 9.2.1 20191008] on linux
Type "help", "copyright", "credits" or "license" for more information.

root@ubuntu18:~# python3.7
Python 3.7.5rc1 (default, Oct  8 2019, 16:47:45) 
[GCC 9.2.1 20191008] on linux
Type "help", "copyright", "credits" or "license" for more information.


//安装依赖包
apt -y install python3-dev libffi-dev libssl-dev zlib*

//源码编译安装python3.6
./configure --enable-optimizations --prefix=/usr/local/python36
make
make altinstall        #防止覆盖原来的版本

//设置环境变量
echo "PATH=/usr/local/python36/bin:$PATH" >/etc/profile.d/python36.sh && source /etc/

//设置pip国内源
mkdir /root/.pip
cat >/root/.pip/pip.conf <<EOF
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
EOF

ubuntu安装python3.6问题

4.更换国内源(ubuntu18.04)

//备份原有文件
cp /etc/apt/sources.list{,.bak}

//设置为阿里云源
cat >/etc/apt/sources.list<EOF
