Linux（Ubuntu18.04）安裝 WICD
無法連接到 wicd 的 D-Bus 接口。錯誤信息請查看 wicd 日志。|
sudo service wicd stop

Linux（Ubuntu18.04）安裝 JDK1.8
Linux（Ubuntu18.04）安裝 Maven
Linux（Ubuntu18.04）安裝 Mysql
解決無法插入中文：
service mysql stop
編輯配置文件
sudo gedit /etc/mysql/my.cnf
service mysql restart
訪問權限配置
mysql -u root -p mysql> update mysql.user set authentication_string=password('訪問數據庫的密碼') where user = 'root'; mysql> flush privileges;
添加用戶訪問數據庫的權限
以xyz賬戶為例添加數據庫hello的訪問權限
mysql> create user xyz; mysql> update mysql.user set authentication_string=password('訪問數據庫的密碼') where user = 'xyz'; mysql> update mysql.user set host=localhost where user = 'xyz'; mysql> grant all privilages on hello.* to 'xyz'@'localhost'; mysql> flush privileges;
設置MySQL遠程訪問的權限
1.編輯mysql的啟動配置文件
sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf
加前綴#注釋掉bind-address = 127.0.0.1
保存並退出gedit
2.授權遠程任意IP地址可以訪問數據庫
mysql> grant all privilages on hello.* to xyz@"%" identified by "訪問數據庫的密碼" with grant option; mysql> flush privileges; mysql> quit
sudo ufw enable sudo ufw default deny sudo ufw allow 3306
3.重啟mysql
sudo /etc/init.d/mysql restart

Linux（Ubuntu18.04）安裝 Solr
1.進入官網下載：https://lucene.apache.org/solr/downloads.html
wget https://www.apache.org/dyn/closer.lua/lucene/solr/8.4.1/solr-8.4.1.tgz
2.解壓：
tar zxvf solr-8.4.1.tgz
Linux（Ubuntu18.04）安裝 QQ/Wechat
參考：https://github.com/wszqkzqk/deepin-wine-ubuntu
克隆 (git clone https://github.com/wszqkzqk/deepin-wine-ubuntu.git) 或下載到本地。
在中國推薦用下面的地址，速度更快： (git clone https://gitee.com/wszqkzqk/deepin-wine-for-ubuntu.git)
當然也可以選擇下載releases：Github 或者 Gitee
解壓后切換到解壓文件目錄，在終端中運行（授予可執行權限后）： ./install.sh
KDE或其他按照普通安裝方式安裝后運行出現X錯誤的桌面環境執行 ./KDE-install.sh ）。
Wine應用的中文框框問題
1.下載Windows的simsun.ttc字體
2.將字體放入~/.wine/drive_c/windows/Fonts 里面，如果是deepin的話，就放在~/.deepinwine/XXX/drive_c/windows/Fonts里面（XXX指deepin下的你安裝的程序）
3.編寫文件zh.reg:
REGEDIT4 [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Arial"="simsun" "Arial CE,238"="simsun" "Arial CYR,204"="simsun" "Arial Greek,161"="simsun" "Arial TUR,162"="simsun" "Courier New"="simsun" "Courier New CE,238"="simsun" "Courier New CYR,204"="simsun" "Courier New Greek,161"="simsun" "Courier New TUR,162"="simsun" "FixedSys"="simsun" "Helv"="simsun" "Helvetica"="simsun" "MS Sans Serif"="simsun" "MS Shell Dlg"="simsun" "MS Shell Dlg 2"="simsun" "System"="simsun" "Tahoma"="simsun" "Times"="simsun" "Times New Roman CE,238"="simsun" "Times New Roman CYR,204"="simsun" "Times New Roman Greek,161"="simsun" "Times New Roman TUR,162"="simsun" "Tms Rmn"="simsun"
4.regedit zh.reg
如果沒有提示就說明注冊成功了，這樣就解決了亂碼問題了

聯想R720無法開啟WIFI解決方法[原文鏈接]
通過列入黑名單的方式來實現自動移出ideapad_laptop設備。 1）創建/etc/modprobe.d/ideapad.conf文件： sudo touch /etc/modprobe.d/ideapad.conf 2）編輯ideapad.conf文件： sudo gedit ideapad.conf 3) 在ideapad.conf文件中添加： blacklist ideapad_laptop 4) 關閉並保存ideapad.conf文件，移除ideapad_laptop設備： sudo modprobe -r ideapad_laptop 5) 注銷重啟Ubuntu系統，可以看到無線設備能夠被打開，並能搜索到WiFi信號。
