【介绍】
Ubuntu 是一个以桌面应用为主的开源 GNU/Linux 操作系统。
Ubuntu 基于 Debian GNU/Linux,支持x86、amd64(即x64)和ppc架构,由全球化的专业开发团队(Canonical Ltd)打造的。
Ubuntu 基于 Debian 发行版和 GNOME 桌面环境,而从11.04版起,Ubuntu 发行版放弃了 Gnome 桌面环境,改为 Unity 。
【工具】
build-essential:
sudo apt-get install build-essential -y
参考:https://tecadmin.net/install-development-tools-on-ubuntu/
libtool等:
sudo apt-get install make libtool libtool-bin m4 autoconf automake libtool git aptitude htop dos2unix zip unzip -y
【更新】
sudo apt-get update -y && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y
或者:
sudo aptitude update -y && sudo aptitude upgrade -y && sudo aptitude dist-upgrade -y
参考:https://ubuntuforums.org/showthread.php?t=1222909
【端口】
参考:https://www.jianshu.com/p/95e5cbd37070
安装:
sudo apt-get install iptables
开启:
iptables -I INPUT -p tcp --dport 端口号 -j ACCEPT
查验:
sudo netstat -tlpn | grep 端口号
如果需要部署网站,需要在Ubuntu系统里开启 80 / 443 两个端口。
iptables -I INPUT -p tcp --dport 80 -j ACCEPT iptables -I INPUT -p tcp --dport 443 -j ACCEPT
【排错】
问题:更新系统时出现 The following packages have been kept back
新开了一个 Ubuntu 22.04 系统,升级系统时出现:
Reading package lists... Done Building dependency tree... Done Reading state information... Done Calculating upgrade... Done The following packages have been kept back: libnss-systemd libpam-systemd libsystemd0 libudev1 systemd systemd-sysv systemd-timesyncd udev 0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.
参考:https://itsfoss.com/following-packages-have-been-kept-back/
The fix for this error is really simple. All you have to do is to use the apt install command with package or packages in the question
参考:https://www.codenong.com/f-following-packages-have-been-kept-back/
解决方法:对问题中的一个或多个软件包使用apt install命令
sudo apt install libnss-systemd libpam-systemd libsystemd0 libudev1 systemd systemd-sysv systemd-timesyncd udev
解决方法:方案是运行 sudo apt-get install 。在大多数情况下,这将为保留的软件包提供成功升级所需的内容。
sudo apt-get install python3-update-manager update-manager-core
问题:WinSCP 以预设密码进行验证 拒绝访问
方法:关闭 WinSCP ,重新登录后,再使用 Putty。
参考:https://blog.csdn.net/weixin_42672685/article/details/123824826
第一次连接Ubuntu,使用 WinSCP 以预设密码进行验证,提示拒绝访问
解决方案:
路径:vim /etc/ssh/sshd_config
PermitEmptyPasswords yes
重启服务
service ssh restart
2.更改密码
3.核对密码再次登录
问题:缺少依赖

参考:https://stackoverflow.com/questions/20680050/how-do-i-install-chkconfig-on-ubuntu
ubuntu中chkconfig已经被sysv-rc-conf替代,具体如下操作如下:
chkconfig: command not found
sysv-rc-conf命令:
sudo apt-get install sysv-rc-conf sysv-rc-conf keepalived on
报错:
Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package sysv-rc-conf

更新apt-get:
sudo apt-get update
安装sysv-rc-conf:
sudo apt-get install sysv-rc-conf -y

【远程桌面:xfce(推荐)】
https://www.codenong.com/f-install-xfce-desktop-xubuntu/
sudo apt install xrdp sudo apt install xfce4
开启端口:
firewall-cmd --zone=public --add-port=3389/tcp --permanent firewall-cmd --zone=public --add-port=22/tcp --permanent firewall-cmd --zone=public --add-port=80/tcp --permanent firewall-cmd --zone=public --add-port=443/tcp --permanent
重新加载:
service firewalld start service firewalld reload firewall-cmd --zone=public --list-ports
【远程桌面:lxde】
参考:https://www.jianshu.com/p/4befb190c94b
参考:https://www.jianshu.com/p/daba3fd81786
sudo apt-get install lxde sudo apt-get install xrdp
打开 Windows 附件自带的远程桌面连接:
参考:https://jingyan.baidu.com/article/cbcede07ce04ee02f40b4d08.html
1. 按 Windows键 + R ,在运行中输入 mstsc
2. 在远程桌面登录框中输入 IP 地址和 Ubuntu 系统的用户名,点击连接,输入密码。
如果无法连结远程桌面:
方案1:关闭防火墙
ufw disable
方案2:配置安全规则
因为没有配置安全规则。添加入出口端口后就行了。
参考:https://blog.csdn.net/blank_tt/article/details/90759891
安全组》配置规则》添加安全组规则
规则方向:入方向
授权策略:允许
协议类型:自定义TCP
端口范围:3389
授权对象:0.0.0.0
之后,在桌面连接中输入凭据即可。
