Tomcat production environment configuration and tomcat production environment

In the window, at the top of catalina. bat:
Set JAVA_OPTS =-XX: PermSize = 64 M-XX: MaxPermSize = 128 m-Xms512m-Xmx1024m;-Duser. timezone = GMT + 08;
It must be added at the top of catalina. bat.

 

In linux, add the following at the beginning of catalina. sh:

JAVA_OPTS = "-XX: PermSize = 64 M-XX: MaxPermSize = 128 m-Xms512m-Xmx1024m-Duser. timezone = Asia/Shanghai"

How to configure tomcat environment variables?

Add the following to the environment variable:
Tomcat_home
E:/java/Tomcat6.0 // Replace the drive letter with your own tomcat.

Others: You have to change it to your own one.
Classpath

.; E: \ Java \ jdk1.6.0 _ 11 \ lib \ dt. jar; E: \ Java \ jdk1.6.0 _ 11 \ lib \ tools. jar

JAVA_HOME
E: \ Java \ jdk1.6.0 _ 11

Path

; E: \ Java \ jdk1.6.0 _ 11 \ bin;

Tomcat_home
E: \ Java \ Apache Tomcat 6.0.18

E: \ Java \ Tomcat 6.0

E: \ oracle \ product \ 10.1.0 \ db_1 \ bin; % SystemRoot % \ system32; % SystemRoot % \ System32 \ Wbem; D: \ Program Files \ MySQL Server 5.0 \ bin; E: \ Java \ jdk1.6.0 _ 11 \ bin

How to configure the environment for tomcat, beginner

System Environment:
1. Operating System: Windows 2000
2. Database: Oracle 8i R2 (8.1.6) for NT Enterprise Edition
3. installation path: C: \ ORACLE

In this example, the software is used:
1、jdk-1.4-win.exe [19.5 MB]
Java.sun.com/
2、jakarta-tomcat.zip [2.26 MB]
Jakarta.apache.org/builds/tomcat/release/v4.06

Installation Method:
The method in () is the directory on my machine, which is easy to use to change the default configuration.

1. Install JDK
Step 1: Install jdk-1_2_006-win.exe using the default configuration
The default installation directory of JDK is C: \ jdk1.4.1, and the default installation directory of JRE is C: \ Program Files \ mongooft \ JRE \ 1.4;
(For future convenience, you can select a well-remembered directory, such as c: \ jdk14 ;)

Step 2: Update Environment Variables
Start> Settings> Control Panel> system> advanced> environment variables> System Variables
The configuration is as follows:

JAVA_HOME = C: \ jdk1.4.1
CLASSPATH =.; % JAVA_HOME % \ lib \ tool. jar; % JAVA_HOME % \ lib \ dt. jar;
PATH =.; % JAVA_HOME % \ bin;

Ii. install Tomcat
Step 1: double-click the downloaded exe file. Enter the default installation path (you can select the installation path, for example, c: \ Tomcat4. Also, if you want to start Tomcat as a service of nt in the future, you can select NT serveer, this option)

Step 2: Double-click startup. bat to start the tomcat server
At this time, a dos window will appear on the screen, and some information about successful tomcat and initialization will be displayed,
Verify that tomcat runs successfully.

Step 4: Enter localhost: 8080/in the browser/
If you can see the Tomcat Version 4.06 page, it indicates that Tomcat is successfully installed.
The files on the page you see are stored in the c: \ jakarta-tomcat \ webapps \ examples directory (c: \ Tomcat4 \ webapps \ examples directory)
There are some examples of jsp and servlet, so far the jsp environment has been built.

Note: The above DOS window cannot be closed; otherwise, the tomcat server will stop service.

Note: JSP files run slowly for the first time

Iii. First JSP Example
Name test. jsp for this program and place it in the c: \ jakarta-tomcat \ webapps \ examples directory (c: \ Tom ...... the remaining full text>
