To put it simply, it is easy to install the software yum and will automatically resolve the dependencies of each package. RPM is just a package.
CentOS to install MySQL5.5 in RPM mode
First go to the http://dev.mysql.com/downloads/mysql/5.5.html#downloads site to download:
Download the following three files separately (since my machine is 32 bits, here is a 32-bit version of the package, if your machine is 64-bit, please download 64-bit version):
mysql-server-5.5.16-1.rhel5.i386.rpm
mysql-client-5.5.16-1.rhel4.i386.rpm
mysql-devel-5.5.16-1.rhel4.i386.rpm
Use the wget command to download these three files using a breakpoint transfer
Wget-c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
Wget-c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
Wget-c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
Start the installation after the download completes:
RPM-IVH mysql-server-5.5.16-1.rhel4.i386.rpm mysql-client-5.5.16-1.rhel4.i386.rpm mysql-devel-5.5.16-1.rhel4.i386.rpm

Cp/usr/share/mysql/my-huge.cnf/etc/my.cnf
Configuring Remote Access
Security considerations, MySQL by default is not allowed remote access, you can use the following to open remote access
Give any host access to data: (www.111cn.net)
Mysql>grant all privileges in *.* to ' root ' @ '% ' with GRANT OPTION
Make the changes take effect
Mysql>flush Privileges
If you still can't access it remotely, it's probably the cause of the firewall, you can open port 3306 in the firewall or simply turn off the firewall.
