一.VMware Fusion自定义网段
1.什么是VMware Fusion
VMware Fusion是VMware公司推出MacOS的虚拟化解决方案,熟悉"VMware Workstation"的小伙伴使用起来很友好。
因为这两个产品均出自一家公司,很多设计套路几乎是一致的。MacOS的用户仅需要个别配置注意下。
2.自定义VMware Fusion网段
1.停止vm网络服务
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop
2.修改网段配置
# sudo vim /Library/Preferences/VMware\ Fusion/networking
...
# 仅需要修改VNET的网段,比如我将网段和子网掩码作如下修改。
answer VNET_8_HOSTONLY_NETMASK 255.255.255.0
answer VNET_8_HOSTONLY_SUBNET 10.0.0.0
3.应用配置生效,会覆盖现有的网络配置文件
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --configure
...
温馨提示:
此步骤,会自动生成"/Library/Preferences/VMware\ Fusion/vmnet8/nat.conf"和"/Library/Preferences/VMware\ Fusion/vmnet8/dhcpd.conf"的配置文件,如果之前修改过的话会直接覆盖哟~
4.启动vm网络服务
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start
二.Ubuntu 22.04LTS基本配置
1.安装ubuntu系统
基于VMware Fusion或者"VMware Workstation"软件环境安装Ubuntu 22.04LTS版本可参考我之前的笔记。

2.配置root用户登陆
1.更新软件源
sudo apt update
sudo apt -y install gdm3 net-tools iputils-ping
2.修改"gdm-password"配置文件
sudo vim /etc/pam.d/gdm-password
...
# auth required pam_succeed_if.so user != root quiet_success
3.修改"gdm-autologin"配置文件
sudo vim /etc/pam.d/gdm-autologin
...
# auth required pam_succeed_if.so user != root quiet_success
4.修改sshd服务的配置文件
sudo vim /etc/ssh/sshd_config
...
PermitRootLogin yes
5.重启sshd服务
sudo systemctl restart sshd
6.配置root的密码
sudo passwd root
3.配置静态IP地址
1.修改网卡的配置文件
root@yinzhengjie:~# cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'

2.应用配置
root@yinzhengjie:~# netplan apply

root@yinzhengjie:~#
3.测试登陆
yinzhengjie@bogon ~ % ssh root@10.0.0.128

4.修改默认的网卡为ens33
1.修改前查看网卡信息
root@yinzhengjie:~# ifconfig

...
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
3.用"grub-mkconfig"工具重新生成新的配置文件

5.配置PS1变量
cat <<EOF >> ~/.bashrc
PS1='[\[\e[34;1m\]\u@\[\e[0m\]\[\e[32;1m\]\H\[\e[0m\]\[\e[31;1m\] \W\[\e[0m\]]# '
EOF
source ~/.bashrc
6.设置登陆界面为字符界面
1.切换到字符界面
[root@yinzhengjie ~]# systemctl set-default multi-user.target
Created symlink /etc/systemd/system/default.target → /lib/systemd/system/multi-user.target.
[root@yinzhengjie ~]#
2.重启操作系统
[root@yinzhengjie ~]# reboot
Connection to 10.0.0.99 closed by remote host.
Connection to 10.0.0.99 closed.
yinzhengjie@bogon ~ %
温馨提示:
我的环境默认安装的Ubuntu系统,对于VMware Fusion虚拟机打开发现是图形化界面,还没有终端可以操作。
因此建议配置完成后,一定要将默认级别设置为字符界面,如果你真的很想用图形化界面,可以使用如下命令。
方法一:
systemctl set-default graphical.target
方案二:
startx
方法三:
init 5
7.修改软件源
1.清华源 22.04 LTS为例:(**/etc/apt/sources.list**)
# 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

8.vim基础优化
1.定义vim文件模板【可自行修改】
[root@yinzhengjie ~]# cat .vimtpl
#!/bin/bash
# Filename: %FILENAME%
# email: y1053419035@qq.com
# Author: 尹正杰(yinzhengjie) Jason Yin
# CurrentUser: %USER%
# Date: %DATE%
# Version: %VERSION%
# Blog: https://www.cnblogs.com/yinzhengjie
# Description:
[root@yinzhengjie ~]#
2.配置vim配置并引用模板
[root@yinzhengjie ~]# cat .vimrc
" 设置字符编码为: utf-8
set encoding=utf-8
" 设置行号
set number
" 设置制表符宽度为4个空格
set tabstop=4
set shiftwidth=4
" 设置自动缩进和智能缩进
set autoindent
set smartindent
" 显示匹配的括号
set showmatch
" 开启自动换行
set wrap
" 开启搜索时忽略大小写
set ignorecase
" 高亮显示当前行
set cursorline
" 搜索时自动高亮匹配
set hlsearch
" 启用文件类型检测
filetype plugin on
filetype indent on
" 设置原样粘贴,避免粘贴变行之类的
autocmd BufRead,BufNewFile * set paste
" 获取当前用户名
let s:current_user = $USER
" 设定默认版本号
let s:default_version = "v0.0.1"
" function! ReplaceTemplateVariables(timer_id)
function! YinZhengJieTpl(timer_id)
let l:current_date = strftime("%Y-%m-%d")
let l:current_filename = expand('%:t')
" 替换对应的占位符
execute "%s/%DATE%/" . l:current_date . "/g"
execute "%s/%FILENAME%/" . l:current_filename . "/g"
execute "%s/%User%/" . s:current_user . "/g"
execute "%s/%VERSION%/" . s:default_version . "/g"
" 设置光标位置
call cursor(9, 20)
endfunction
" 安装 Timer 插件(如果尚未安装)
if !exists('g:loaded_timer') && !exists('g:did_timer_plugin')
silent! timer defer timer_start 1
let g:did_timer_plugin = 1
endif
" 调用模板
autocmd BufNewFile *.sh 0r ~/.vimtpl | call timer_start(100, 'YinZhengJieTpl')
[root@yinzhengjie ~]#
3.测试效果,如上图所示
[root@yinzhengjie ~]# vim yinzhengjie-autoinstall-docker.sh
