输出可以直接写入新服务器的已建立好的分区， 也可以设置目录保存为文件。

从6升级到7，建议按步骤走一遍弄个机器测试升级，玩坏了自己买单。

随后生成pem和key 直接在http服务器上绑定即可以使用。

又是一年秋季，有些人手的手掌脱皮，指尖脱皮龟裂且裂口出外翻。
如果只是脱皮其实还好，也就手掌的掌纹变白皮肤犹如枯枝扎人，但是如果指尖脱皮又开裂，就生不如死没，一是痛二是指尖的触觉犹如覆盖了一层502胶水。
我的解决办法是在发现贴创口贴的地方皮肤明显更加湿润和热水泡胀手脚皮肤去角质层想到的，然后跑药店买了几幅医用手套，
在睡前洗涂抹新鲜的肉芦荟（用护手霜或甘油也可以）再戴手套睡觉，反复折腾几天后皮肤就恢复了正常机能。
如果情况严重的建议先去医院断诊。

最近几年的一些营销号和自媒体的视频和文章都特别+非常+特别非常喜欢带上“众所周知”。
一些特点 视频内容多数是东拼西凑出来的或者搬运过来重新配音并打上LOGO，
常用语 “众所周知” “小伙伴们怎么看？” “各位网友怎么看” “各位网友如何如何”
文稿内容只要能看到“众所周知”可以判断100%是自媒体营销号，然后通篇内容就是视频配音读稿的文案一字不改直接发出来，有时候看着看着都能自动脑补BGM。
还有一类更恶劣的，直接看图编内容，东拼西凑出来狗屁不通的洗稿见闻内容。
这拨人给人的感觉好像都是一个窝里面的， 和UC震惊部一样一样的，不知道啥时候才是头，这些想蟑螂的傻逼才会死翘翘进垃圾桶。

Shell大致流程
1.获取网络IP配置参数
2.写入自定义grub引导内核
2.1 http://103.xxx.xxx.xxx/kickstart.php/rh?end=1&ethworkaround=1是预设定的anaconda-ks自动响应安装脚本。
3.修改grub默认配置参数等待时间和指定引导顺序。
4. 重新生成grub2配置
5.重启等待安装完成。
最后建议在NoVNC或者IPMi辅助的情况下使用。
vmlinuz的网络参数还有一种写法是 ip=address::gateway:netmask:hostname:interface:method
getETH=`ip -4 route list 0/0 |awk '{ print $5 }'`
getGATEWAY=`ip -4 route list 0/0 |awk '{ print $3 }'`
getNETMASK=`ifconfig $getETH | awk '/mask /{ print $4;}'`
getIPADDR=`ifconfig $getETH | awk '/inet /{ print $2;}'`

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
