所需模块:


Curses

DBI Distributed as Bundle::DBI:

DBD::mysql

Getopt::Long (Distributed with Perl 5)

Net::Domain Part of libnet:

 

# perl -e use Curses

# perl -e use DBI

# perl -e use DBD::mysql

# perl -e use Getopt::Long

# perl -e use Net::Domain

 

没有输出就是模块已经安装了,有错误就是相应的模块没有安装。


可以在上面给出的地址下载相应模块的最新版本。

 

安装所需的 Perl 模块:

# tar zxvf Curses-x.xx.tar.gz

# cd Curses*

# perl Makefile.PL

# make

# make install

 

yum仓库里有 perl-DBI ,所以直接 yum 安装


# yum -y install perl-DBI

 

因为是编译安装的 MySQL ,所以需要把 lib 的路径加入 ld.so.conf


# vi /etc/ld.so.conf

/usr/local/mysql/lib/mysql

# ldconfig

 

虽然yum仓库里有 perl-DBD-MySQL ,但其依赖 mysql ,所以还是编译安装


# tar zxvf DBD-mysql-x.xxxx.tar.gz

# cd DBD-mysql*

# perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config

# make

# make install

 

安装mtop:


# tar zxvf mtop-0.6.6.tar.gz

# cd mtop-0.6.6

# perl Makefile.PL

# make

# make install

 

添加相应的MySQL数据库用户:

# mysql -uroot -pPASSWORD

mysql> GRANT RELOAD,PROCESS,SUPER ON *.* TO IDENTIFIED BY mtop;

mysql> FLUSH PRIVILEGES;

mysql> exit

 

运行:


因为自定义了 mysql.sock 的位置,所以需要做个链接 mtop 才能运行,


# ln -s /var/run/mysqld/mysql.sock /tmp/mysql.sock

 

# mtop --dbuser=mtop --password=mtop

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.
