How to install MySql in Linux

Create users and user groups first
Su-Root
Groupadd MySQL
Useradd-G MySQL decompress the binary file.
Tar zxvf mysql-5.0.51a-linux-i686.tar.gz
Copy the directory/home/MySQL to/usr/local. Create the MySQL license table:
[Root @ localhost root] # cd/usr/local/MySQL
[Root @ localhost MySQL] # scripts/mysql_install_db -- user = MySQL sets binary ownership to be owned by root and belongs to the MySQL Management Group:
[Root @ localhost MySQL] # chown-r root/usr/local/MySQL
[Root @ localhost MySQL] # chgrp-r MySQL/usr/local/MySQL:
[Root @ localhost MySQL] # chown-r MySQL/usr/local/MySQL/Data start server: different database servers use different commands to start the server, for example, if I install the MySQL-server-5.1.7-0.i386.rpm, so use it at startup
[Root @ localhost root] # service MySQL start instead of [root @ localhost root] # service mysqld start
Then it is shown as follows:
Starting MySQL success!
The errors may be as follows:
[Root @ localhost MySQL] # bin/MySQL-umysql
Error 2002 (hy000): Can't connect to local MySQL server through socket '/tmp/MYS
QL. Sock '(2)
Solution:
I went to the mysql. Sock file, under the/var/lib/MySQL. Sock directory, and then found the/tmp directory.
Then, log in as follows:
[Root @ localhost MySQL] # bin/MySQL-uroot-P
Enter password:
