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.
