ubuntu16.04环境下软件启动，但是不显示软件界面

作者：系统库时间：2018-05-07人气：

新装的ubuntu16.04操作系统，然后安装pycharm，第一次安装成功，可是启动时，不显示软件界面；卸载后重装，安装界面都不显示；然后用命令行进行安装，启动软件后，依然不能切换到软件界面。后来Alt+Tab，发现软件明明已经启动。

原因是系统默认了两个或者多个数据显示端口，启动软件时，软件界面出现在了当前显示屏以外的输出端口。可以用命令查看当前启动的输出端口：

xrandr

有一个显示端口有分辨率数据，说明当前只有一个显示输出端口。如果有两个显示端口有分辨率数据，说明当前有两个输出端口，从而导致软件启动，而不能显示软件画面。此时我们需要关掉那个隐藏的输出端口。

方法1

在终端下，关闭多余窗口

xrandr --output 显示端口名称 --off

方法2

系统设置-> 显示，手动关掉一个显示输出。

注意：如果关错了，导致黑屏，重新启动显示器即可。

如何创建定制的Ubuntu Live CD镜像

今天让我们来讨论一下如何创建 Ubuntu Live CD 的定制镜像（ISO）。我们以前可以使用 Pinguy Builder 完成这项工作。但是，现在它似乎停止维护了。最近 Pinguy Builder 的官方网站似乎没有任何更新。幸运的是，我找到了另一种创建 Ubuntu Live CD 镜像的工具。使用 Cubic （即 Custom Ubuntu ISO Creator 的首字母缩写），这是一个用来创建定制的可启动的 Ubuntu Live CD（ISO）镜像的 GUI 应用程序。

Cubic 正在积极开发，它提供了许多选项来轻松地创建一个定制的 Ubuntu Live CD ，它有一个集成的 chroot 命令行环境（注：chroot —— Change Root，也就是改变程序执行时所参考的根目录位置），在那里你可以定制各种方面，比如安装新的软件包、内核，添加更多的背景壁纸，添加更多的文件和文件夹。它有一个直观的 GUI 界面，在 live 镜像创建过程中可以轻松的利用导航（可以利用点击鼠标来回切换）。您可以创建一个新的自定义镜像或修改现有的项目。因为它可以用来制作 Ubuntu live 镜像，所以我相信它可以用在制作其他 Ubuntu 的发行版和衍生版镜像中，比如 Linux Mint。

安装 Cubic

Cubic 的开发人员已经做出了一个 PPA 来简化安装过程。要在 Ubuntu 系统上安装 Cubic ，在你的终端上运行以下命令:

sudo apt-add-repository ppa:cubic-wizard/release

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E

sudo apt update

sudo apt install cubic

利用 Cubic 创建 Ubuntu Live CD 的定制镜像

安装完成后，从应用程序菜单或 dock 启动 Cubic。这是在我在 Ubuntu 16.04 LTS 桌面系统中 Cubic 的样子。

为新项目选择一个目录。它是保存镜像文件的目录。

请注意，Cubic 不是创建您当前系统的 Live CD 镜像，而是利用 Ubuntu 的安装 CD 来创建一个定制的 Live CD，因此，你应该有一个最新的 ISO 镜像。

选择您存储 Ubuntu 安装 ISO 镜像的路径。Cubic 将自动填写您定制操作系统的所有细节。如果你愿意，你可以改变细节。单击 Next 继续。

接下来，来自源安装介质中的压缩的 Linux 文件系统将被提取到项目的目录（在我们的例子中目录的位置是 /home/ostechnix/custom_ubuntu)。

一旦文件系统被提取出来，将自动加载到 chroot 环境。如果你没有看到终端提示符，请按几次回车键。

在这里可以安装任何额外的软件包，添加背景图片，添加软件源列表，添加最新的 Linux 内核和所有其他定制到你的 Live CD 。

例如，我希望 vim 安装在我的 Live CD 中，所以现在就要安装它。

我们不需要使用 sudo，因为我们已经在具有最高权限（root）的环境中了。

类似地，如果需要，可以安装更多的任何版本 Linux 内核。

apt install linux-image-extra-4.10.0-24-generic

此外，您还可以更新软件源列表（添加或删除软件存储库列表）：

修改源列表后，不要忘记运行 apt update 命令来更新源列表：

apt update

另外，您还可以向 Live CD 中添加文件或文件夹。复制文件或文件夹（右击它们并选择复制或者利用 CTRL+C），在终端右键单击（在 Cubic 窗口内)，选择 “Paste file(s)”，最后点击 Cubic 向导底部的 “Copy”。

Ubuntu 17.10 用户注意事项

在 Ubuntu 17.10 系统中，DNS 查询可能无法在 chroot 环境中工作。如果您正在制作一个定制的 Ubuntu 17.10 Live 镜像，您需要指向正确的 resolve.conf 配置文件：

ln -sr /run/systemd/resolve/resolv.conf /run/systemd/resolve/stub-resolv.conf

要验证 DNS 解析工作，运行:

cat /etc/resolv.conf

ping google.com

如果你想的话，可以添加你自己的壁纸。要做到这一点，请切换到 /usr/share/backgrounds/ 目录

cd /usr/share/backgrounds

并将图像拖放到 Cubic 窗口中。或复制图像，右键单击 Cubic 终端窗口并选择 “Paste file(s)” 选项。此外，确保你在 /usr/share/gnome-backproperties 的XML文件中添加了新的壁纸，这样你可以在桌面上右键单击新添加的图像选择 “Change Desktop Background” 进行交互。完成所有更改后，在 Cubic 向导中单击 “Next”。

接下来，选择引导到新的 Live ISO 镜像时使用的 Linux 内核版本。如果已经安装了其他版本内核，它们也将在这部分中被列出。然后选择您想在 Live CD 中使用的内核。

在下一节中，选择要从您的 Live 映像中删除的软件包。在使用定制的 Live 映像安装完 Ubuntu 操作系统后，所选的软件包将自动删除。在选择要删除的软件包时，要格外小心，您可能在不知不觉中删除了一个软件包，而此软件包又是另外一个软件包的依赖包。

接下来， Live 镜像创建过程将开始。这里所要花费的时间取决于你定制的系统规格。

镜像创建完成后后，单击 “Finish”。Cubic 将显示新创建的自定义镜像的细节。

如果你想在将来修改刚刚创建的自定义 Live 镜像，不要选择“ Delete all project files, except the generated disk image and the corresponding MD5 checksum file”（除了生成的磁盘映像和相应的 MD5 校验和文件之外，删除所有的项目文件**），Cubic 将在项目的工作目录中保留自定义图像，您可以在将来进行任何更改。而不用从头再来一遍。

要为不同的 Ubuntu 版本创建新的 Live 镜像，最好使用不同的项目目录。

利用 Cubic 修改 Ubuntu Live CD 的定制镜像

从菜单中启动 Cubic ，并选择一个现有的项目目录。单击 “Next” 按钮，您将看到以下三个选项：

1.Create a disk image from the existing project. （从现有项目创建一个磁盘映像。）

2.Continue customizing the existing project.（继续定制现有项目。）

3.Delete the existing project.（删除当前项目。）

第一个选项将允许您从现有项目中使用之前所做的自定义设置创建一个新的 Live ISO 镜像。如果您丢失了 ISO 镜像，您可以使用第一个选项来创建一个新的。

第二个选项允许您在现有项目中进行任何其他更改。如果您选择此选项，您将再次进入 chroot 环境。您可以添加新的文件或文件夹，安装任何新的软件，删除任何软件，添加其他的 Linux 内核，添加桌面背景等等。

第三个选项将删除现有的项目，所以您可以从头开始。选择此选项将删除所有文件，包括新生成的 ISO 镜像文件。

我用 Cubic 做了一个定制的 Ubuntu 16.04 LTS 桌面 Live CD。就像这篇文章里描述的一样。如果你想创建一个 Ubuntu Live CD，Cubic 可能是一个不错的选择。

ubuntu17.10安装LAMP并测试部署php探针系统

步骤1、ubuntu17.10配置IP (这个版本配置IP方式改变较大，apt-get upgrade更新至最新以前配置方式也可以用了)

root@ubuntu:~# vi /etc/netplan/01-netcfg.yaml

# This file describes the network interfaces available on your system

# For more information, see netplan(5).

network:

version: 2

renderer: networkd

ethernets:

ens32:

dhcp4: no

dhcp6: no

addresses: [192.168.10.222/24]

gateway4: 192.168.10.1

nameservers:

addresses: [61.134.1.5, 114.114.114.114]

配置修改保存后执行命令让配置生效：

root@ubuntu:~# netplan apply

步骤2、安装 Apache Web Server

输入以下命令来安装Apache Web服务器。该apache2-utils包将安装一些有用的实用程序，如Apache HTTP服务器基准测试工具（ab）。

root@ubuntu:~# sudo apt install -y apache2 apache2-utils

安装完成后，应自动启动Apache。使用systemctl检查其状态。

root@ubuntu:~# systemctl status apache2.service

apache2.service - The Apache HTTP Server

Jan 22 22:14:47 ubuntu systemd[1]: Started The Apache HTTP Server.

如果没有运行，请使用systemctl启动它。使Apache启动时自动启动也是一个好方法

root@ubuntu:~# sudo systemctl start apache2

root@ubuntu:~# sudo systemctl enable apache2

Synchronizing state of apache2.service with SysV service script with /lib/systemd/systemd-sysv-install.

Executing: /lib/systemd/systemd-sysv-install enable apache2

启动后浏览器测试IP是否可以打开访问

现在我们需要将www-data（Apache用户）设置为文档根目录的所有者。默认情况下，它由root用户拥有。

root@ubuntu:~# sudo chown www-data:www-data /var/www/html/ -R

步骤3、安装 MariaDB 数据库服务器

MariaDB是MySQL的替代品。输入以下命令将其安装在Ubuntu 17.10上。

root@ubuntu:~# sudo apt install mariadb-server mariadb-client

Reading package lists... Done

Building dependency tree

Reading state information... Done

The following additional packages will be installed:

galera-3 libaio1 libcgi-fast-perl libcgi-pm-perl libdbd-mysql-perl

libhtml-tagset-perl libhtml-template-perl libhttp-date-perl

libhttp-message-perl libio-html-perl libjemalloc1 liblwp-mediatypes-perl

安装完毕后，MariaDB服务器应自动开启。使用systemctl检查其状态。

root@ubuntu:~# systemctl start mariadb

root@ubuntu:~# systemctl enable mariadb //开机自动自动

root@ubuntu:~# systemctl status mariadb

mariadb.service - MariaDB 10.1.30 database server

Jan 22 22:34:51 ubuntu systemd[1]: Started MariaDB 10.1.30 database server.

现在运行安装后的安全脚本。

sudo mysql_secure_installation

当它要求您输入MariaDB root密码时，按Enter键，因为root密码尚未设置。然后输入y设置MariaDB服务器的root密码。

root@ubuntu:~# sudo mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current

password for the root user. If you've just installed MariaDB, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB

root user without the proper authorisation.

Set root password? [Y/n] y

New password:

Re-enter new password:

##后面的设置选项按需选择即可

默认情况下，Ubuntu上的MaraiDB软件包使用unix_socket对用户登录进行身份验证，这主要表示您可以使用操作系统的用户名和密码登录到MariaDB控制台。因此，您可以运行以下命令登录，而不提供MariaDB root密码。

root@ubuntu:~# sudo mariadb -u root

Welcome to the MariaDB monitor. Commands end with ; or \g.

Your MariaDB connection id is 10

Server version: 10.1.30-MariaDB-0ubuntu0.17.10.1 Ubuntu 17.10

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>exit

Bye

步骤4、安装 PHP7.1

在选写本文时，PHP7.1是PHP的最新稳定版本，在PHP7.0上具有较小的性能优势。输入以下命令来安装PHP7.1。

root@ubuntu:~# sudo apt install php7.1 libapache2-mod-php7.1 php7.1-mysql php-common php7.1-cli php7.1-common php7.1-json php7.1-opcache php7.1-readline

php7.1-mysql php7.1-opcache php7.1-readline

PHP 7.1.11-0ubuntu0.17.10.1 (cli) (built: Nov 1 2017 16:30:52) ( NTS )

要使用Apache服务器测试PHP脚本，我们需要在文档根目录中创建一个info.php文件。

root@ubuntu:~# sudo vi /var/www/html/info.php

将以下PHP代码粘贴到文件中。

phpinfo()
