ssh config常用配置

vim ~/.ssh/config

Host    别名
    HostName        主机名
    Port            端口
    User            用户名
    IdentityFile    密钥文件的路径

有了这些配置，就可以这样用 ssh 登陆服务器了：

ssh 别名

如果遇到Bad owner or permissions错误，执行以下语句：

sudo chmod 600 config

拷贝ssh key

ssh-copy-id 别名

gedit中文乱码解决

终端配置

gsettings set org.gnome.gedit.preferences.encodings auto-detected "['UTF-8', 'GB18030', 'GB2312', 'GBK', 'BIG5', 'CURRENT', 'UTF-16']"
gsettings set org.gnome.gedit.preferences.encodings shown-in-menu "['UTF-8', 'GB18030', 'GB2312', 'GBK', 'BIG5', 'CURRENT', 'UTF-16']"

使用dconf-tools工具进行配置

yum install dconf-tools，然后运行dconf-editor(ctrl+f2)，依次点开->org->gnome->gedit->preferences->encodings设置如上即可

windows安装go-sqlite3失败，提示找不到gcc

go get github.com/mattn/go-sqlite3时失败，提示exec: "gcc": executable file not found in %PATH%，是因为没有安装gcc。

去http://tdm-gcc.tdragon.net/download下载一个，32位windows下载 tdm-gcc-4.8.1-3.exe，64位下载 tdm64-gcc-4.8.1-3.exe

sudo无需密码

编辑sudo配置文件

# sudo visudo
your_user_name ALL=(ALL) NOPASSWD: ALL

不起作用？

原因是被后面的group的设置覆盖了，需要把group的设置也改为nopasswd

%wheel  ALL=(ALL)       NOPASSWD: ALL
