2. Decompression and installation

[root@www src] # tar zxf jdk-8u65-linux-x64.tar.gz

[root@www src] # mv jdk1.8.0_65 / usr/local/

3. Set environment variables

[root@www src] # vim / etc/profile.d/java.sh

JAVA_HOME=/usr/local/jdk1.8.0_65

JAVA_BIN=/usr/local/jdk1.8.0_65/bin

JRE_HOME=/usr/local/jdk1.8.0_65/jre

PATH=$PATH:/usr/local/jdk1.8.0_65/bin:/usr/local/jdk1.8.0_65/jre/bin

CLASSPATH=/usr/local/jdk1.8.0_65/jre/lib:/usr/local/jdk1.8.0_65/lib:/usr/local/jdk1.8.0_65/jre/lib/charsets

.jar

4. Initialize

[root@www src] #. / etc/profile.d/java.sh / / same as source

[root@www src] # source / etc/profile.d/java.sh

[root@www src] # which java

/ usr/local/jdk1.8.0_65/bin/java

[root@www jdk1.8.0_65] # export PATH JAVA_HOME JAVA_BIN JRE_HOME CALSSPATH

5. View the version

[root@www src] # java-version

Java version "1.8.0mm 65"

Java (TM) SE Runtime Environment (build 1.8.0_65-b17)

Java HotSpot (TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

Second, install Tomcat

2. Decompression and installation

[root@www src] # tar zxf apache-tomcat-8.0.30.tar.gz

[root@www src] # mv apache-tomcat-8.0.30 / usr/local/tomcat

[root@www src] # ls / usr/local/tomcat/

Bin conf lib LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp webapps work

3. Copy the startup script

[root@www src] # cd / usr/local/tomcat/

[root@www tomcat] # cp-v bin/catalina.sh / etc/init.d/tomcat

`bin/catalina.sh'-> `/ etc/init.d/tomcat'

4. Set up boot boot

[root@www tomcat] # chmod 755 / etc/init.d/tomcat

[root@www tomcat] # chkconfig-- add tomcat

Service tomcat does not support chkconfig / / service does not support

Resolve:

[root@www tomcat] # vim / etc/init.d/tomcat / / add the following at the beginning

#! / bin/sh

# chkconfig: 2345 63 37

# description: tomcat server init script

# Source Function Library

. / etc/init.d/functions

JAVA_HOME=/usr/local/jdk1.8.0_65

CATALINA_HOME=/usr/local/tomcat

[root@www tomcat] # chkconfig-- add tomcat

[root@www tomcat] # chkconfig tomcat on

5. Start Tomcat

[root@www jdk1.8.0_65] # / etc/init.d/tomcat start

Using CATALINA_BASE: / usr/local/tomcat

Using CATALINA_HOME: / usr/local/tomcat

Using CATALINA_TMPDIR: / usr/local/tomcat/temp

Using JRE_HOME: / usr/local/jdk1.8.0_65/jre

Using CLASSPATH: / usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

Tomcat started.

View tomcat processes

[root@www ~] # ps aux | grep tomcat

Root 3835 2.1 7.8 2722304 78704 pts/1 Sl 02:26 0:05 / usr/local/jdk1.8.0_65/jre/bin/java-Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager-Djava.endorsed.dirs=/usr/local/tomcat/endorsed-classpath / usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar-Dcatalina. Base=/usr/local/tomcat-Dcatalina.home=/usr/local/tomcat-Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start

Root 3867 0.0 103248 884 pts/1 S+ 02:30 0:00 grep tomcat

[root@www ~] # / etc/init.d/tomcat stop

[root@www ~] # / etc/init.d/tomcat start

6. Access testing

Enter http://192.168.1.21:8080 in the browser

III. Configuration and optimization of Tomcat

1. Modify the listening port

(1) stop the process of installing nginx to prevent port 80 from being occupied

[root@www ~] # / etc/init.d/nginx stop

Stopping Nginx: [OK]

[root@www ~] # chkconfig nginx off

(2) modify the tomcat listening port to 80

[root@www ~] # cd / usr/local/tomcat/conf/

[root@www conf] # ls

Catalina catalina.properties logging.properties tomcat-users.xml web.xml

Catalina.policy context.xml server.xml tomcat-users.xsd

[root@www conf] # vim server.xml
