Installation under Linux / CentOS7.0 configuration Tomcat8.0
A. Configuring Tomcat installation environment
1. Download the corresponding jdk
http://www.Oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
I use 64-bit download address:
http://download.oracle.com/otn-pub/java/jdk/8u40-b25/jdk-8u40-linux-x64.tar.gz
After downloading the jdk under pressure into the / usr / local directory:
2. Establish / usr / local / jdk soft connection to facilitate future upgrades under version:
# Ln -s /usr/local/jdk1.8.0_40/ / usr / local / jdk
3. Environment Variables
Add the following line in / etc / profile in
JAVA_HOME = / usr / local / jdk1.8.0_40
JAVA_BIN = / usr / local / jdk1.8.0_40 / bin
PATH = $ PATH: $ JAVA_BIN
CLASSPATH = $ JAVA_HOME / lib / dt.jar: $ JAVA_HOME / lib / tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
Save and exit
[Root @ master ~] source / etc / profile
See java environment variable is in effect
[Root @ localhost local] # java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (rhel-2.4.5.5.el7-x86_64 u51-b31)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)
Note: I configure JAVA environment variable when JDK is jdk1.8.0_40, run java -version get is 1.7.0_51
This shows that the system gcj carried JAVA environment variable priority access to the execution right. The solution is to set like the above
export PATH = $ JAVA_HOME / bin: $ PATH, pay attention to the $ PATH into the final. (If placed before the above-mentioned problem occurs)
# Java -version
java version "1.8.0_40"
Java (TM) SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot (TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
Prior to mounting you can uninstall:
[Root @ local src] # rpm -qa | grep java
java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el6_5.x86_64
rpm -e java-version-openjdk java-version-openjdk-devel according to their own version.
two. Tomcat8.0.20 Download:
http://mirrors.cnnic.cn/apache/tomcat/tomcat-8/v8.0.20/bin/apache-tomcat-8.0.20.tar.gz
#tar xzf apache-tomcat-8.0.20.tar.gz // decompression
#mv apache-tomcat-8.0.20 / usr / local / tomcat
#vim /usr/local/tomcat/bin/catalina.sh
Add: CATALINA_HOME = / usr / local / tomcat
chmod + x * .sh
three. Start tomcat server
1. Firewall Release 80
# / Etc / sysconfig / iptables // open with VI
-A INPUT -p tcp -m state -state NEW -m tcp -dport 80 -j ACCEPT // add a sentence to release 80
#cd / usr / local / tomcat / bin /
#. / Startup.sh // start tomcat
four. In the browser input test
http: // localhost: 8080 (if not the machine, enter the corresponding ip address)
Testing indicates that the test page appears tomcat success!
V. modify and add the port test application
ps: Note that the default test page tomcat webapps is placed below, in fact, this is server.xml configuration file, as follows:
