MySQL failure under Linux

Because a lot of failure problems are not, so in the process of recording are mostly statements, not so intuitive, the original intention is more like a record of their own resolution process, of course, if you have encountered the same problem, do not understand also can message contact, hope to help busy.

Build an application platform on a Linux system, use Tomcat, MySQL, execute programs, databases, patches are packaged together, directly installed on the line. Install Linux encountered problems, external CD-ROM installation RHEL5.1, industrial computer motherboard direct connection keyboard, the initial installation interface (text mode prompts the Linux text place) keyboard can not press the key, let it automatically enter the installation, the keyboard will be used, the BIOS can also recognize the keyboard, has confirmed that non-keyboard, interface , wiring problems, no solution. Fortunately the problem is not big, after entering does not install the desktop on the line.

After the system is installed, the Integration Package Deployment certification system (Tomcat and so on a series of programs) more smoothly. Then import the previously backed up SQL data into the Mysql,web page to restart the service with problems. The general meaning is "unable to connect to the database." Using the Mysqlyog tool, you can enter MySQL normally, which means that MySQL is turned on and normal. Then the root user password is cleared out. Failure remains. Looking for Niang, the problem may be due to the MySQL process conflict, resulting in MySQL can not restart, good, kill the MySQL process, restart programs and services. Done, the data import was successful.
