RouterOS导入key登陆ssh

Linux或者Mac OS生成一个key

ssh-keygen -t rsa

用scp上传到Mikrotik

scp -P端口 ~/.ssh/id_rsa.pub [email protected]:id_rsa.pub

在Mikrotik内导入key

[[email protected]] > /user ssh-keys import public-key-file=id_rsa.pub user=admin

打印查看

[[email protected]] > /user ssh-keys print
Flags: R - RSA, D - DSA        
 #   USER                       BITS KEY-OWNER        
 0 R admin                      2048 XXXXXXX

dd安装Routeros

wget http://download2.mikrotik.com/routeros/6.43.8/chr-6.43.8.img.zip -O chr.img.zip && \

gunzip -c chr.img.zip > chr.img && \

mount -o loop,offset=33554944 chr.img /mnt && \

ADDRESS0=`ip addr show eth0 | grep global | cut -d' ' -f 6 | head -n 1` && \

GATEWAY0=`ip route list | grep default | cut -d' ' -f 3` && \

echo "/ip address add address=$ADDRESS0 interface=[/interface ethernet find where name=ether1]

/ip route add gateway=$GATEWAY0

" > /mnt/rw/autorun.scr && \

umount /mnt && \

CentOS7重新生成 /boot/grub2/grub.cfg

修改/etc/default/grub

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet"

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto enforcing=0 vconsole.keymap=us rhgb quiet"

添加 enforcing=0 或者net.ifnames=0 biosdevname=0

GRUB_DISABLE_LINUX_UUID=true

存盘退出

执行 grub2-mkconfig --output /boot/grub2/grub.cfg

MacOS修改单个应用程序默认语言

背景

Mac系统语言设置的是英文，安装的Office语言默认也是英文。由于习惯了中文Office的使用，想把Office的语言设置成中文，    
方法之一就是直接修改系统的默认语言设置，但并不希望直接修改系统语言，仅想修改Office软件的默认语言

实现

1获取App的Bundle Identifier

Bundle Identifier是应用软件的标识，以Microsoft Word为例，Terminal中输入命令：

mdls -name kMDItemCFBundleIdentifier /Applications/Microsoft\ Word.app

2得到结果：

kMDItemCFBundleIdentifier = "com.microsoft.Word"

3修改应用程序默认语言

该操作需要用到第一步查到的应用程序Bundle Identifier，本例中是com.microsoft.Word，Terminal中输入命令：

defaults write com.microsoft.Word AppleLanguages '("zh_CN")'
