虚拟机MAC改变后，无法启动，并报错：“Device eth0 does not seem to be present”
出现该问题，是由于MAC地址变更后，操作系统仍然保留原来MAC地址作为eth0，并且将新的MAC地址识别为新的网卡导致的，可以删除文件“/etc/udev/rules.d/70-persistent-net.rule”中老MAC的信息，并把新MAC中的eth1改成eth0，通过start_udev重新加载udev，然后重启网卡恢复：“service network restart”

买了linksys wrt1200ac很久了，之前只是装了一个openwrt+默认配置，也没启用什么特别功能，感觉还算稳定。不过现在想听一些下载下来的广播，但又不想总是开着PC，所以突然想把这些音频挪到没用的u盘里，并挂在openwrt中，这样任何设备都可以访问了，还剩资源:)

定制OpenWRT

1. 安装中文包

root@OpenWrt:~# opkg update <<< 每次重启后需要缓存安装包列表，这样才能search到所有可用的包
root@OpenWrt:~# opkg list |grep zh-cn <<< 学会如何查找相应的包
root@OpenWrt:~# opkg install luci-i18n-base-zh-cn <<< 安装中文包

2.安装luci的主题

默认只有一种，在默认更新源里，加上默认的一共有4个，最后我还是选择了默认的 -_-

root@OpenWrt:~# opkg list |grep -i theme
luci - git-16.018.33482-3201903-1 - Standard OpenWrt set including full admin with ppp support and the default Bootstrap theme
luci-theme-bootstrap - git-16.018.33482-3201903-1 - Bootstrap Theme (default)
luci-theme-freifunk-bno - git-16.018.33482-3201903-1 - Freifunk Berlin Nordost Theme
luci-theme-freifunk-generic - git-16.018.33482-3201903-1 - Freifunk Generic Theme
luci-theme-openwrt - git-16.018.33482-3201903-1 - LuCI OpenWrt.org theme

在处理工作时，常常遇到统计log，但如何高效的统计，常常需要度娘，而且查起来也很麻烦，所以统计到blog里，下次可以统一查阅：

Excel中两列数据，找出重复项

参考文章请查看：https://zhidao.baidu.com/question/546059662.html
分别对两行建立条件公式，选中A列，条件“=COUNTIF(B:B,A1)>0”；选中B列，条件“=COUNTIF(A:A,B1)>0”，如下所示：

Introduction

After installed Centos 6.7 for CISCO WAE, I found python version is 2.6 that is much older, and I need ansible1.9, but Centos default upgrade to ansible2.2… in order to easy management ansible1.9 that is python package, I plan to install PIP. From official website, suggest not use 2.6 under pip, so I need to upgrade python to 2.7 too.

But I found WAE use 2.6 after I succeed upgrade python to 2.7…Summarized the totally steps that will help me review in future.
