Ii. Software Installation
1. First install Sun's JDK
[Root @ yangwenjun www] #./j2sdk-1_4_2_09-linux-i586.bin

After installation, the j2sdk1.4.2 _ 09 folder will be generated, and the j2sdk1.4.2 _ 09 folder will be moved (or copied) to the JDK location you want to store. This article is in/home/www/j2sdk1.4.2 _ 09
Next, edit the/etc/profile file and add the JDK environment variable. Add the following content to the end of the file:

[Root @ yangwenjun www] # vi/etc/profile

Export JAVA_HOME =/home/www/j2sdk1.4.2 _ 09
Export CLASSPATH =.: $ CLASSPATH: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar
: $ JAVA_HOME/lib/mysql-connector-java-3.2.0.jar: $ JAVA_HOME/lib/classes12.jar
Export PATH = $ PATH: $ JAVA_HOME/bin
Export JRE_HOME = $ JAVA_HOME/jre

[Root @ yangwenjun etc] # source profile
[Root @ yangwenjun etc] # set

Here you can see all the environment variables.
[Root @ yangwenjun etc] # java? Version
If the JDK configuration is correct, the corresponding JDK version will appear when you run the above command.

2. Install MySQL

[Root @ yangwenjun www] # tar xzfv mysql-standard-4.1.14-pc-linux-gnu-i686.tar.gz
[Root @ yangwenjun www] # cd mysql-standard-4.1.14-pc-linux-gnu-i686
[Root @ yangwenjun mysql-standard-4.1.14-pc-linux-gnu-i686] # more INSTALL-BINARY

Read this document carefully and you will find that MySQL is easy to install.

[Root @ yangwenjun mysql-standard-4.1.14-pc-linux-gnu-i686] # groupadd mysql
[Root @ yangwenjun mysql-standard-4.1.14-pc-linux-gnu-i686] # useradd-g mysql
[Root @ yangwenjun www] # mv mysql-standard-4.1.14-pc-linux-gnu-i686/home/www/mysql
[Root @ yangwenjun www] # cd/home/www/mysql
[Root @ yangwenjun mysql] # scripts/mysql_install_db -- user = mysql
[Root @ yangwenjun mysql] # chown-R root.
[Root @ yangwenjun mysql] # chown-R mysql data
[Root @ yangwenjun mysql] # chgrp-R mysql.
[Root @ yangwenjun mysql] # bin/mysqld_safe -- user = mysql &

In this way, MySQL has been started, and the following sets the password for the root user:

[Root @ yangwenjun mysql] #./bin/mysqladmin-u root password 'Password'
[Root @ yangwenjun mysql] #./bin/mysqladmin-u root-h localhost. localdomain password 'pass'
[Root @ yangwenjun mysql] #./bin/mysql-u root-p
Enter password:
Welcome to the MySQL monitor. Commands end with; or \ g.
Your MySQL connection id is 5 to server version: 4.1.14-standard

Type 'help; 'or' \ H' for help. Type '\ C' to clear the buffer.

Mysql>

[Root @ yangwenjun mysql] # cp support-files/mysql. server/etc/init. d/mysql
[Root @ yangwenjun mysql] # vi/etc/init. d/mysql
Modify the following definition to make the content:
Basedir =/home/www/mysql
Datadir =/home/www/mysql/data
[Root @ yangwenjun mysql] # chkconfig -- level 345 mysql on
[Root @ yangwenjun mysql] # service mysql restart
Shutting down MySQL... [OK]
Starting MySQL [OK]
[Root @ yangwenjun mysql] #
