卷組擴容
Linux mint采用默認卷組的安裝方式

提高效率技巧：
1. 建立永久快捷鍵
參照上面的圖示編輯用戶目錄下的.bashrc文件，添加一行：alias ll="ls?-l" 保存退出
然后用source ~/.bashrc（或者 . ~/.bashrc）使修改立刻生效。
2. 為軟件建立快捷啟動命令模仿subl命令的寫sain@Linux /opt/scitools/bin/linux64 $ which subl
/usr/bin/subl sain@Linux /opt/scitools/bin/linux64 $ cat /usr/bin/subl #!/bin/sh exec /opt/sublime_text/sublime_text "$@"
創建文件 /usr/bin/understand
文件添加exec /opt/scitools/bin/linux64/understand
chmod a+x /usr/bin/understand

1. 安裝ssh服務：
先安裝sudo apt-get install openssh-server
后安裝sudo apt-get install openssh-client
?顯示sshd則表示服務安裝成功
sain@Linux ~/Desktop $ ps -A | grep ssh*
1214 ? 00:00:00 cinnamon-sessio

2. sougou輸入法,網易云音樂,wps,visualstudiocode

http://pinyin.sogou.com/linux/
http://community.wps.cn/download/
https://code.visualstudio.com/?wt.mc_id=DX_841432
安裝完sogoupinyin_2.2.0.0102_amd64.deb之后，需要安裝fctix.重啟
應用程序中搜素fcitx configuration,添加搜狗輸入法
?
3. 安裝shadowsocks
通過PPA源安裝，僅支持Ubuntu?14.04或更高版本。
打開終端
sudo?add-apt-repository?ppa:hzwhuang/ss-qt5
sudo?apt-get?update
sudo?apt-get?install?shadowsocks-qt5
?4.安裝Guake Terminal和sublime
sudo apt-get install guake
另外可參考
sublime安裝參考：
1.下載sublime text3 deb包 wget https://download.sublimetext.com/sublime-text_build-3103_amd64.deb 2.安裝sublime text3 sudo dpkg -i sublime-text_build-3103_amd64.de
?
?5. AndroidStudio 配置
歸一化配置：
sdk目錄：?
~/Android_tools/sdk
啟動快捷方式：（不一定有效）
[Desktop Entry] Version=1.0 Type=Application Name=AndroidStudio2.3 Comment=AndroidStudio Icon=/opt/android-studio/bin/studio.png Exec=/opt/android-studio/bin/studio.sh Terminal=false StartupNotify=tr
?
更好的方法是啟動androidstudio，Tools菜單下直接創建
?
6. deepin root 賬號設置
deepin系統默認是沒有為root賬號設置密碼的，需要執行下面的指令?
sudo passwd root
?
7.開機自動掛載分區
編輯系統/etc/fstab 文件，默認是以UUID區分各分區
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda7 during installation UUID=20c18c6c-7fc0-4c30-bd9f-d5df7095f2da / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda6 during installation UUID=0ba8d57e-a628-40ad-a106-aa3d56f21ff2 /boot ext4 defaults 0 2 # /home was on /dev/sda8 during installation UUID=55b3eb18-13c2-4e34-90f6-4df36bf449fa /home ext4 defaults 0 2 # swap was on /dev/sda5 during installation UUID=31ed8d6a-2575-4990-8ee5-0f101eb8b975 none swap sw 0 0
查看硬盤信息，可以看到UUID和分區的其實有一一對應關系：
sain@Linux ~/Desktop $ sudo blkid [sudo] password for sain: /dev/sda1: LABEL="ESP" UUID="F46C-A96B" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="af5dc20b-b10b-4391-85b2-05e30732df65" /dev/sda3: LABEL="OS" UUID="F2369D40369D06AF" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="ca736ee9-c841-49b9-bd67-454d8e6b7c1e" /dev/sda4: LABEL="Data" UUID="D20C9C1D0C9BFAA5" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="de967f44-f620-4234-b310-6f500384768c" /dev/sda5: UUID="31ed8d6a-2575-4990-8ee5-0f101eb8b975" TYPE="swap" PARTUUID="e7c24756-5ba1-4155-8242-7acee14a432c" /dev/sda6: UUID="0ba8d57e-a628-40ad-a106-aa3d56f21ff2" TYPE="ext4" PARTUUID="f898d6c1-8992-495d-9764-a62c1adb3ab1" /dev/sda7: UUID="20c18c6c-7fc0-4c30-bd9f-d5df7095f2da" TYPE="ext4" PARTUUID="5b45a43d-c981-4f52-adea-53158b5ba79c" /dev/sda8: UUID="55b3eb18-13c2-4e34-90f6-4df36bf449fa" TYPE="ext4" PARTUUID="89854a0e-f085-498d-852e-1afa819d8675" /dev/sda9: LABEL="WINRETOOLS" UUID="F6A0BFFCA0BFC203" TYPE="ntfs" PARTUUID="667d7919-0759-4c4b-8b02-51fbc2f380b2" /dev/sda2: PARTLABEL="Microsoft reserved partition" PARTUUID="97ac0bb1-226a-48b2-8745-343f3827b0d5"
所以，簡單起見，掛在某個硬盤
只需要/etc/fstab?在末尾加上一句，保存,重啟實現開機自動掛載?
/dev/sda4 /media/sain/Data ntfs defaults 0 0
defaults?等于rw,suid,dev,exec,auto,nouser,async
fstab參數解釋

安裝軟件可能出現的問題：
情況1：
E: 有未能滿足的依賴關系。請嘗試不指明軟件包的名字來運行“apt-get -f install”(也可以指定一個解決辦法)。
說明：
因為安裝的時候出現了一點問題，最后apt-get的包依賴關系被我搞亂了
解決辦法：
在終端輸入：apt-get -f install
然后在輸入：
sudo apt-get install flex
情況2：
有的時候，使用sudo apt-get install可能導致意想不到的錯誤，尤其是中途中斷了安裝時，錯誤信息為：
Errors were encountered while processing:
ttf-dustin
khangman
kdeedu
kde
E: Sub-process /usr/bin/dpkg returned an error code (1)
此時可以這樣解決：
cd /var/lib/dpkg
sudo mv info info.bak
sudo mkdir info
重新安裝，在此為：
sudo apt-get --reinstall install ttf-dustin khangman kdeedu kde
?

win7 遠程桌面ubuntu16.04

使用win10遠程控制ubuntu16.04
| 使用win10遠程控制ubuntu16.04，網上很多需要安裝xfce桌面的。今天介紹一下，不需要安裝其他桌面，使用Ubuntu16.04自帶桌面，漂亮美觀。 Ubuntu16.04端： 1、打開終端，安裝xrdp,vncserver sudo apt-get install xrdp vnc4server xbase-clients 2、安裝desktop sharing（Ubuntu16.04默認已經安裝），可以到應用商店下載。打開desktop sharing，設置如下：  3、安裝安裝dconf-editor，取消權限限制： sudo apt-get install dconf-editor dconf-editor設置：org > gnome > desktop > remote-access，取消 “requlre-encryption” Win10端： 搜索遠程桌面連接，輸入Ubuntu的ip地址，點擊連接。  選擇vnc-any，輸入Ubuntu的ip地址，端口不變（5900），桌面共享設定的密碼，即可遠程連接到ubuntu 16.04桌面。 參考http://www.linuxdiyf.com/linux/27078.html dconf-editor有一定概率啟動不了 Starting dconf-editor: imediately crashes:(dconf-editor:15007): GLib-GIO-ERROR **: Settings schema 'ca.desrt.dconf-editor.Settings' is not installedTrace/breakpoint trap (core dumped) sudo glib-compile-schemas /usr/share/glib-2.0/schemas/ |
?誤刪/var/lib/dpkg/info 解決辦法
1、手動新建info目錄：
mkdir/var/lib/dpkg/info
2、重新刷新軟件安裝列表
?
sudo apt-get upgrade sudo apt-get install dis-upgrade把所有的軟件更新
ubuntu samba配置
安裝samba
sudo apt get-install samba
啟動時碰到一堆問題，結果發現是由于/etc/samba/smb.conf文件不存在
新建該文件

valid user = ninjame
browseable = yes

?
[aosp]
comment = public share
guest ok = yes

[ftp]
comment = public share
guest ok = yes
dos charset = UTF-8
unix charset = UTF-8
display charset = UTF-8
path = /home/sain/ftp
browseable = yes
writable = yes
增加samba密碼
sudo ?smbpasswd ?-a user，新增用戶，該用戶和ubuntu用戶不是一回事，一定要加sudo，否則沒有任何提示
重啟服務
sudo service smbd restart
?
安裝samba過程可能有些過于激進的操作，系統只能進入高級選項，選擇一個特定的版本重啟，且無法進入正常界面
考慮將系統內核進行升級
參考：http://www.linuxidc.com/Linux/2017-03/141940.htm

以上命令在用戶目錄~下執行就可以，安裝后在/boot 目錄生成新文件
下載完成這些所有內核文件后，如下安裝：
$?sudo?dpkg?-i?*.deb
?
安裝完成后，重啟并驗證新的內核已經被使用了：
$?uname?-sr
就是這樣。你下次就可以使用比 Ubuntu 16.04 默認安裝的內核的更新版本了。
?
安裝搜狗輸入法
用 im-config 命令打開一個配置器窗口
默認是ibus，需要修改為 fcitx
重啟 ubuntu 系統就可以了。
