某天机器由于断电+UPS 供电不足重启后,,发现监听器启不起来了,提示错误:
TNSLSNR for Linux: Version 10.2.0.1.0 - Production

检查磁盘空间 df -h 仍然是有空间可以使用的
奇怪,同时df -i 检查了一下 inodes 使用情况,很吃惊,/var 目录下 inodes 全部耗尽了
[oracle@newadm log]$ df -i

联系SA检查 /var 目录下 inodes 耗尽的原因,并删除那些小文件后,监听器正常启动了
之后参考 eygle 的文章,检查了一下,发现监听器启动的时候,在 /var/tmp/.oracle 目录下生成了两个临时文件,所以当 /var 目录下的 Inodes 耗尽的时候,监听器无法启动。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
