1 . 先在 header 宣告：
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";
2. 再 subject 再宣告為：
$subject = "=?UTF-8?B?".base64_encode($subject)."?=";
這樣發送後主旨的地方就不會再有亂碼。

新增一些帳密資料，或都測試寫scirpt 時，都會不小時把敏感的資料keyin 在 console ，那有心人士只要下 history 可得知你之前下的指令。
之前都會在退出console 時下 history -c 清除歷史資料，但有時候太忙就是會忘記，累積幾次後，祕密全被看看。
在 google 找到一篇文章，有記載以下方式：
# vi /etc/profile
> HISTCONTROL=ignorespace
# source /etc/profile (讓 profile 的設定，立即生效。)
example：
# mysql -uadmin -p"test1234"
# history (就會出現剛剛下過的指令)
mysql -uadmin -p"test1234"
改用 ignorespace 的用法：
#<space>mysql -uadmin -p"test1234" # <space> 代表一個空白鍵
# history
就不會出現剛剛下過的指令，之後在做敏感資料時，都可以在指令前多空一個空白，就不會記錄在 history 中。

Wed Apr 29 15:33:33 2009] [error] (24)Too many open files: could not open mime types config file /etc/mime.types.
解決方法：
# nlimit -n
> 1024 (預設值)
# nlimit -n 8192
# nlimit -n
> 8192 (新值)
# service httpd restart
因為重開機後, nlimit -n 會變為預設值(1024), 需要更改 /etc/security/limit.conf 加入 nlimit -n 8192 。 但這樣 Apache 啟動時還是出現錯誤，於是在 /etc/rc.d/init.d/httpd 中加入 nlimit -n 8192 後，就順利啟動。

因為資料中有mysql 保留字，所以在匯入時會出現錯誤訊息。
可以利用phpmyadmin 的匯出功能，特別勾選「在資料表及欄位使用引號」，即可正常匯入，但儘量避免使用保留字
mysql 資料表中有保留字匯出方法如下：

0001 0002 0003 0004 0005 0006 |
# vi .htaccess
Options +FollowSymLinks
# sudo -u username ln -s source target
// 加上 sudo -u user 建立出來是symlinks 的權限是 user 而不是 root, 才不會出現 Error 403。
