Linux（Ubuntu18.04）安装 Mysql
解决无法插入中文：
service mysql stop
编辑配置文件
sudo gedit /etc/mysql/my.cnf
service mysql restart
访问权限配置
mysql -u root -p mysql> update mysql.user set authentication_string=password('访问数据库的密码') where user = 'root'; mysql> flush privileges;
添加用户访问数据库的权限
以xyz账户为例添加数据库hello的访问权限
mysql> create user xyz; mysql> update mysql.user set authentication_string=password('访问数据库的密码') 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;
设置MySQL远程访问的权限
1.编辑mysql的启动配置文件
sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf
加前缀#注释掉bind-address = 127.0.0.1
保存并退出gedit
2.授权远程任意IP地址可以访问数据库
mysql> grant all privilages on hello.* to xyz@"%" identified by "访问数据库的密码" with grant option; mysql> flush privileges; mysql> quit
sudo ufw enable sudo ufw default deny sudo ufw allow 3306
3.重启mysql
sudo /etc/init.d/mysql restart

Linux（Ubuntu18.04）安装 QQ/Wechat
参考：https://github.com/wszqkzqk/deepin-wine-ubuntu
克隆 (git clone https://github.com/wszqkzqk/deepin-wine-ubuntu.git) 或下载到本地。
在中国推荐用下面的地址，速度更快： (git clone https://gitee.com/wszqkzqk/deepin-wine-for-ubuntu.git)
当然也可以选择下载releases：Github 或者 Gitee
解压后切换到解压文件目录，在终端中运行（授予可执行权限后）： ./install.sh
KDE或其他按照普通安装方式安装后运行出现X错误的桌面环境执行 ./KDE-install.sh ）。
Wine应用的中文框框问题
1.下载Windows的simsun.ttc字体
2.将字体放入~/.wine/drive_c/windows/Fonts 里面，如果是deepin的话，就放在~/.deepinwine/XXX/drive_c/windows/Fonts里面（XXX指deepin下的你安装的程序）
3.编写文件zh.reg:
REGEDIT4 [HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionFontSubstitutes] "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
如果没有提示就说明注册成功了，这样就解决了乱码问题了

联想R720无法开启WIFI解决方法[原文链接]
通过列入黑名单的方式来实现自动移出ideapad_laptop设备。 1）创建/etc/modprobe.d/ideapad.conf文件： sudo touch /etc/modprobe.d/ideapad.conf 2）编辑ideapad.conf文件： sudo gedit ideapad.conf 3) 在ideapad.conf文件中添加： blacklist ideapad_laptop 4) 关闭并保存ideapad.conf文件，移除ideapad_laptop设备： sudo modprobe -r ideapad_laptop 5) 注销重启Ubuntu系统，可以看到无线设备能够被打开，并能搜索到WiFi信号。
