[转]Linux /home下中文目录如何修改成英文？

export LANG=en_US.UTF-8

xdg-user-dirs-gtk-update

跳出对话框询问是否将目录转化为英文路径,同意并关闭.
在终端中输入命令:

export LANG=zh_CN.UTF-8

关闭终端,并重起.下次进入系统,系统会提示是否把转化好的目录改回中文.选择不再提示,并取消修改.主目录的中文转英文就完成了~

produced an unexpected error: ‘ascii’ codec can’t decode byte 0xe9 in position

把配置文件里的中文字符串删除就好了

  1. $ sudo grep -r -P ‘[^\x00-\x7f]’ /etc/apache2 /etc/letsencrypt /etc/nginx
  2. 將看到的內容，全部進去檔案刪除
  3. 刪除這些編碼後，在重新執行 Let’s encrypt script 就可以通過囉~
Attempting to renew cert (www.xxx.com) from /etc/letsencrypt/renewal/www.xxx.com.conf produced an unexpected error: 'ascii' codec can't decode byte 0xe9 in position 5: ordinal not in range(128). Skipping.
All renewal attempts failed. The following certs could not be renewed:

2.增加2个路由表分别是电信：a0 联通：b1
# vi /etc/iproute2/rt_tables
252 a0
251 b1
ip route flush table a0
ip route add default via 172.31.16.1 dev eth0 src 172.31.17.107 table a0
ip rule add from 172.31.17.107 table a0

ip route flush table b1
ip route add default via 172.31.32.1 dev eth1 src 172.31.43.225 table b1
ip rule add from 172.31.43.225 table b1

openssl_private_encrypt 最大只能加密117字符😂

On my PHP5 build, the limit is 117 characters (936 bits, strange number). That’s because public key encryption is CPU intensive, and meant to be used on short values. The idea is to use this function to encrypt a secret key that is in turn used to encrypt data using a more efficient algorithm, such as RC4 or TripleDES.openssl_public_encrypt
