Hostname:balichvm (192.168.171.51)

JDK version:jdk1.7.0_79

Tomcat version:apache-tomcat-7.0.64

1), download, configure JDK

[Email protected] ~]# cd/usr/local/src/

[Email protected] src]# wgethttp://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz # Download

[[Email protected] src]# tar zxvfjdk-7u79-linux-x64.tar.gz # Unzip

[[Email protected] src]# MV JDK1.7.0_79//USR/LOCAL/JDK # Move program and rename

2), configure the JDK environment variables, in the/etc/profile.d/ directory, edit a java.sh Java environment variable file, configured as follows

[Email protected] src]# vim/etc/profile.d/java.sh

Java_home=/usr/local/jdk

Java_bin=/usr/local/jdk/bin

Jre_home=/usr/local/jdk/jre

Path= $PATH:/usr/local/jdk/bin:/usr/local/jdk/jre/bin

Classpath=/usr/local/jdk/jre/lib:/usr/local/jdk/lib:/usr/local/jdk/jre/lib/charsets.jar

Save configuration file

[Email protected] src]# source/etc/profile.d/java.sh

[[email protected] src]# java–version # test environment variables are normal

Java Version "1.7.0_79"

Java (TM) SE Runtime Environment (BUILD1.7.0_79-B15)

[Email protected] src]# wgethttp://archive.apache.org/dist/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz

[[Email protected] src]# tar zxvf apache-tomcat-7.0.64.tar.gz # Unzip

[Email protected] src]# Mvapache-tomcat-7.0.64/usr/local/tomcat

[Email protected] src]# cd/usr/local/tomact/

[[email protected] tomact]# Cp-pvbin/catalina.sh/etc/init.d/tomcat # copy Launch Script

"Bin/catalina.sh", "/etc/init.d/tomcat"

[[email protected] tomact]# Vim/etc/init.d/tomcat # Edit startup script, support chkconfig

Java_home=/usr/local/jdk

Catalina_home=/usr/local/tomcat

Save the configuration file, and then add Tomcat to the System Services list

[Email protected] tomact]# chmod 755/etc/init.d/tomcat

[Email protected] tomact]# chkconfig--addtomcat

[[Email protected] tomcat]# service Tomcatstart

Using catalina_base:/usr/local/tomcat

Using Catalina_home:/usr/local/tomcat

Using catalina_tmpdir:/usr/local/tomcat/temp

Using Jre_home:/USR/LOCAL/JDK

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

Tomcat started.

[Email protected] tomcat]#

at this point,Tomcat has started, you can use PS and netstat to view the process and open ports,Tomcat default port is 8080, can be accessed by the browser (note firewall rules).

If there is a iptables rule, add the rule release:

-A input-m state--state new-m tcp-p tcp--dport 8080-j ACCEPT

4),tomcat configuration and optimization (combined with JSP)

The default listener port for Tomcat is 8080, which can be modified on the configuration file server.xml . The file is in the Conf directory under the Tomcat installation directory , here is :/usr/local/tomcat/conf/server.xml

To Configure a virtual host, in Tomcat , each virtual host is used with the <Host> </Host> pair to appear.

first need to build the directory of the site to /data/javaweb , the domain name is java.balichvm.org, configured as follows:

[[email protected] tomcat]# Mkdir/data/javaweb # Create a Site Directory

[Email protected] tomcat]# Vim/usr/local/tomcat/conf/server.xml

Find </Host> next line Insert new <Host> content as follows :

Unpackwars= "false" autodeploy= "true"

xmlvalidation= "Flase" xmlnamespaceaware= "Flase" >

<context path= "" docbase= "./" debug= "0" reloadable= "true" crosscontext= "true"/>

</Host>

Restart the Tomcat service because Tomcat does not support restart, stop first, and then start.

in the/data/javaweb directory to write a jsp file, using a Java time function, if the normal display of the current time, it indicates that the JSP environment is basically OK.

[Email protected] tomcat]# vim/data/javaweb/timenow.jsp

<body>

<center> now time is <%=new java.util.Date ()%></center>

</body>

Save the file, test it.

[[Email protected] tomcat]# Date
