RHEL
一、环境说明:
复制代码 代码如下:
[root@beanvm ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)
[root@beanvm ~]# uname -a
Linux beanvm 2.6.32-220.el6.i686 #1 SMP Wed Nov 9 08:02:18 EST 2011 i686 i686 i386 GNU/Linux
二、准备工作与系统配置
1.下载安装包
这里下载的是较新的MySQL 5.6.16版本,更新迭代的太快了,文件为:mysql-5.6.16.tar.gz
下载地址:http://dev.mysql.com/downloads/mysql/
2. 安装编译必须的包
复制代码 代码如下:
[root@beanvm ~]# rpm -ivh bison-devel-2.4.1-5.el6.i686.rpm
warning: bison-devel-2.4.1-5.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]

[root@beanvm ~]# rpm -ivh ncurses-devel-5.7-3.20090208.el6.i686.rpm
warning: ncurses-devel-5.7-3.20090208.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
Preparing... ########################################### [100%]
1:ncurses-devel ########################################### [100%]
个人经验上面两个包是比较容易缺失,像gcc,make,cmake则是必备的了,也建议检查一下:
复制代码 代码如下:
[root@beanvm ~]# rpm -qa |grep gcc-c++
gcc-c++-4.4.6-3.el6.i686
[root@beanvm ~]# rpm -qa |grep make
imake-1.0.2-11.el6.i686
automake-1.11.1-1.2.el6.noarch
cmake-2.6.4-5.el6.i686
make-3.81-19.el6.i686
3.创建MySQL用户和组
复制代码 代码如下:
[root@beanvm ~]# groupadd mysql
[root@beanvm ~]# useradd -g mysql mysql
[root@beanvm ~]# passwd mysql
4.配置环境变量
复制代码 代码如下:
[root@beanvm ~]# su

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
