Programing Reference For .Net,Java,C

  JAVA operating environment: j2sdk-1_4_2_05 

  Database server: MySQL-4.0.20d 

  Web server: Tomcat5.0.27 

  JDBC Driver: mysql-connector-java-3.0.14-production-bin.jar 

  1, the structures of the operating environment JAVA JAVA 

  (1) to download j2sdk-Sun 1_4_2_05-linux-i586-rpm.bin 

  (2) documents to executable files: 

  [Root @ eframe62 tuzq] # chmod + x j2sdk-1_4_2_05-linux-i586-rpm.bin 

  (3) the implementation of self-extracting files: 

  [Root @ eframe62 tuzq] # ./j2sdk-1_4_2_05-linux-i586-rpm.bin 

  (4) decompress files generated rpm j2sdk-1_4_2_05-linux-i586-rpm, installation rpm: 

  [Root @ eframe62 tuzq] # rpm-ivh j2sdk-1_4_2_05-linux-i586-rpm 

  (5) files are installed in / usr/java/j2sdk1.4.2_05 directory, in order to facilitate the / usr directory to be a simple connection: 

  [Root @ eframe62 usr] # ln-s / usr/java/j2sdk1.4.2_05 jdk 

  (6) by adding environment variables: 

  [Root @ eframe62 usr] # export JAVA_HOME = / usr / jdk 

  [Root @ eframe62 usr] # export CLASSPATH = $ JAVA_HOME / lib: $ JAVA_HOME / jre / lib:. 

  [Root @ eframe62 usr] # export PATH = $ PATH: $ JAVA_HOME / bin: $ JAVA_HOME / jre / bin 

  (7) Test JAVA operating environment: write a procedure to verify java 
  [Root @ eframe62 usr] # vi HelloWorld.java 
  Importation of the following: 

  Public class HelloWorld ( 

  Public static void main (String args []) ( 

  System.out.println ( "Hello, Wrold"); 

  ) 

  ) 

  Write and withdraw from the Editor: 

  : Wq 

  [Root @ eframe62 usr] # javac HelloWorld.java 

  (No error) 

  [Root @ eframe62 usr] # java HelloWorld 

  Hello, World 
  In this way, JAVA operating environment built well. 

  2, MySQL database installation 

  MySQL database server can be downloaded to www.mysql.com.    Is a binary version (compiler) mysql-standard-4.0.20-pc-linux-i686.tar.gz, installation is as follows: 

  (1) increase and called mysql user groups: 

  [Root @ eFrame62 root] # groupadd mysql 

  [Root @ eFrame62 root] # useradd-g mysql mysql 

  (2) to decompress the file / usr / local directory: 

  [Root @ eFrame62 root] # cd / usr / local 

  [Root @ eFrame62 local] # gunzip </ home/tuzq/mysql-standard-4.0.20-pc-linux-i686.tar.gz | tar xvf – 

  (3) the creation of a user-friendly links: 

  [Root @ eFrame62 local] # ln-s / usr/local/mysql-standard-4.0.20-pc-linux-i686 mysql 

  (4) The Executive mysql_install_db script, initialize the database (creates system database and table): 

  [Root @ eFrame62 local] # cd mysql 

  [Root @ eFrame62 mysql] # scripts / mysql_install_db - user = mysql 

  Below if a similar mistake, and - force parameters: 

  Neither host 'eframe62' and 'localhost' could not be looked up with. / Bin / resolveip 

  (5) amend the owner: 

  [Root @ eFrame62 mysql] # chown-R root. 

  [Root @ eFrame62 mysql] # chown-R mysql data 

  [Root @ eFrame62 mysql] # chgrp-R mysql. 

  (6) launched the database server: 

  [Root @ eFrame62 mysql] # bin / mysqld_safe - user = mysql & 

  RPM is another version, including: MySQL-server-4.0.20-0.i386.rpm (server) and MySQL-client-4.0.20-0.i386.rpm (client).    Implementation of the following command to install, will automate the operation, launched good server: 

  Rpm-ivh MySQL-server-4.0.20-0.i386.rpm 

  Rpm-ivh MySQL-client-4.0.20-0.i386.rpm 

  NOTE: RPM version of the MySQL installation directory vary, there are some directory below: 

  L / usr / bin: Customer procedures and scripts 

  L / usr / sbin: mysqld service program 

  L / var / lib / mysql: database and the log file 

  If we can not start normal service may need to be modified / var / lib / mysql for the owner of mysql: 

  Chown-R mysql: mysql / var / lib / mysql 

  MySQL initial root password is empty, needs to be revised.    In order to use your tools (such as the Windows graphical tools) remote connectivity, the need to increase access: 

  [Root @ eFrame62 mysql] # mysql-u root-p 

  Mysql> use mysql 

  Mysql> grant all privileges on *.* to root @ "%" identified by'012345 'with grant option; 

  The above can be ordered from the arbitrary creation of a machine to the Super root login account, password is 012345.    In this way, the easy-to-use graphical tool can login and operation, including revising the root password. 

  3, installation of Tomcat 

  Www.jakarta.org can download Tomcat, is a binary packages (compiler): jakarta-tomcat-5.0.27.tar.gz. 

  (1) to extract the files to / usr / local directory 

  [Root @ eFrame62 local] # gunzip </ home/tuzq/jakarta-tomcat-5.0.27.tar.gz | tar xvf – 

  (2) create easy-to-use link 

  [Root @ eFrame62 local] # ln-s / usr/local/jakarta-tomcat-5.0.27.tar.gz tomcat 

  (3) a path JDK 

  [Root @ eFrame62 local] # cd tomcat 

  [Root @ eFrame62 tomcat] # vi bin / catalina.sh 

  Catalina.sh add in the beginning: 

  Export JAVA_HOME = / usr / jdk 

  Export CLASSPATH = $ JAVA_HOME / lib: $ JAVA_HOME / jre / lib:. 

  Export PATH = $ PATH: $ JAVA_HOME / bin: $ JAVA_HOME / jre / bin 

  (4) start Tomcat 

  [Root @ eFrame62 tomcat] # bin / startup.sh 

  In the browser type http:// machines domain name or IP Address: 8080 /, Tomcat welcome interface will be displayed. 

  (5) To stop the Tomcat 

  [Root @ eFrame62 tomcat] # bin / shutdown.sh 

  (6) in the system start to start automatically when Tomcat, in the / etc / rc.d / rc.local adding: 

  / Usr / local / tomcat / bin / startup.sh 

  (7) Management of Tomcat 

  Laws / usr / local / tomcat / conf / tomcat-users.xml increase administrator account (need to restart Tomcat): 

  [Root @ eFrame62 tomcat] # vi conf / tomcat-users.xml 

  In "tomcat-users> adding his party: 

  <user Username="admin" password="" roles="admin,manager"/> 

  In the browser type http:// machines domain name or IP Address: 8080 / admin, an administrator log-in management interface. 

  (8) Create content Context 

  Creating standards for Web applications (such as quickstart) include: WEB-INF directory, and there are classes lib directory. 

  One approach is to copy the whole directory / usr / local / tomcat / webapps / directory to restart Tomcat, will be automatically loaded. 

  Another method is to copy an entire directory to a directory (eg / home / tuzq / quickstart), in the management interface, the left choose Tomcat Server / Service (Catalina) / Host (localhost), the right of the Host Actions drop-down box Select Create New Context, designated Document Base for the / home / tuzq / quickstart designated Path to / quickstart; In order to use JNDI, Use Naming set to True. 

  In this way, the machine can http:// domain name or IP Address: 8080 / quickstart visit Web application content. 

  (9) set JDBC 

  In order to access the specified database, corresponding to the JDBC driver (here mysql-connector-java-3.0.14-production-bin.jar) copied to the / usr / local / tomcat / common / lib, in the Tomcat will be automatically activated when the load
