Configuration and installation of Jdk and Tomcat and jdktomcat

I. jdk installation and configuration

3. Create a soft link to configure/usr/local/src/jdk1.8.0 _ 60 to/etc/profile. Create two soft links first:

(1) original directory/usr/local/src/jdk1.8.0 _ 60

Ln-s/usr/local/src/jdk1.8.0 _ 60 java

(2) original directory/usr/local/src/jdk1.8.0 _ 60/lib

Ln-s/usr/local/src/jdk1.8.0 _ 60/lib javalib

 

4. Configure the environment variables. Edit vi/etc/profile and insert the following three statements to the end of the profile file.

Export JAVA_HOME = (/usr/java/jdk1.7.0 _ 25) is changed to the first soft link java
Export CLASSPATH = (/usr/java/jdk1.7.0 _ 25/lib ).
Export PATH = $ JAVA_HOME/bin: $ PATH

5. The source/etc/profile takes effect for the configuration information, that is, the inserted three-board Command Execution

6. Output JAVA_HOME and CLASSPATH. If the output is a soft link to be provisioned, it indicates that it is successful; otherwise, it is false.

7. Check the java version. Run the following command: java-version.

Ii. Tomcat installation and configuration

1. First create a directory, mkdir tomcat4

Move the tomcat compressed package file to tomcat 4

Mv/usr/local/src/apache-tomcat-9.0.0.M8.tar.gz/usr/local/tomcat4

Decompress the package

 

A. then unzip the file/usr/local/tomcat4/apache-tomcat-9.0.0.M8/bincommons-daemon-native.tar.gz

B. Then go to/usr/local/tomcat4/apache-tomcat-9.0.0.M8/bin/commons-daemon-1.0.15-native-src/unix to find configure

 

C. assign a value to configure, chmod 777 configure, and then run the configure command:./configure (gcc and yum install gcc must be installed in centos)

 

D. Compile make

 

E. Find the jsvc directory in/usr/local/tomcat4/apache-tomcat-9.0.0.M8/bin/commons-daemon-1.0.15-native-src/unix/and then move jsvc up the two-tier directory cp jsvc ../../

2. First write a soft link to/usr/local/src/apache-tomcat-9.0.0.M8,

Ln-s/usr/local/src/apache-tomcat-9.0.0.M8 virtuat4,

 

Configure environment variables, vim/etc/profile

 

3. Execute the configuration file first

After the file takes effect, output it to see if tomcat is configured successfully.

 

4. Modify tomcat port number,/usr/local/tomcat4/apache-tomcat-9.0.0.M8/conf # server. xml, change the port number to 8060

5. in/etc/init. d/Add daemon. the soft link of sh must be in/etc/init. d/directory to create a soft link ln-s/usr/local/tomcat4/apache-tomcat9.0.0.M8/bin/daemon. sh tomcat4 as the tomcat Startup Program

6. Grant the directory permission chown-R tomcat: tomcat/usr/local/tomcat4

Start/etc/init. d/tomcat4 start

Tail-500f/usr/local/tomcat4/apache-tomcat-9.0.0.M8/logs/catalina-daemon.out

Note: Modify the inbound and outbound rules of the firewall.
