LINUX Configuration Javaweb Project three major steps

A: Install the JRE, the following steps used in the Vim editor, if not familiar with can refer to the = http://www.cnblogs.com/lovling/p/7808494.html

01: Download SERVER-JRE Installation package = http://www.oracle.com/technetwork/java/javase/downloads/server-jre9-downloads-3848530.html

02: Unzip to/usr/lib/java directory

03: Modify environment variable file with VIM editor = Vim/etc/environment

04: Write content = # Note: jdk1.8.0_151 is the folder name after decompression

Java_home= "/usr/lib/java/jdk1.8.0_151"
Classpath= "$JAVA _home/lib"
Path= "$JAVA _home/bin"

05: Install JRE = sudo update-alternatives--install/usr/bin/java java/usr/lib/java/jdk1.8.0_151/bin/java 300

06: Choose JRE = sudo update-alternatives--config java

The JRE selection appears and the version you just installed is selected according to the version

07: Test environment is installed successfully = Java-version (if the correct version number is installed successfully)

Two: Install the TOMCAT server

01: Download the corresponding version of Tomcat = http://tomcat.apache.org/

02: Unzip to the appropriate location as needed = The author installs in the/root directory

04: Configure Web Admin Account # = Vi/root/apache-tomcat-9.0.1/conf/tomcat-users.xml

Note: apache-tomcat-9.0.1 is the extracted file name

Write content =

<tomcat-users>
<user name= "account" password= "password" roles= "Admin-gui,manager-gui"/>
</tomcat-users>

05: Configure the Web Access port = vi/root/apache-tomcat-9.0.1/conf/server.xml

Modify <connector port= "8080" protocol= "http/1.1" connectiontimeout= "20000" redirectport= "8443"/>

For <connector port= "protocol=" http/1.1 "connectiontimeout=" 20000 "redirectport=" 8443 "/>

06: Go in the server startup and shutdown directory = CD /root/apache-tomcat-9.0.1/bin

Start Command = =./startup.sh Note:./cannot be omitted

Close Command = =./shutdown.sh

07:tomcat 8, do not allow non-native access to the project management interface, if you want to open permissions

Need to go to VI./root/apache-tomcat-9.0.1/webapps/manager/meta-inf/context.xml

Comment or delete all content within the context tab

Three: Firewall configuration

01: Open the server listening port for externally accessible 80 as an example (this port is consistent with the port configured above, the default is 8080)

02: Set Port Outbound access =/sbin/iptables-i input-p tcp--dport 80-j ACCEPT

03: Save Settings = Service Iptables Save

04: Restart Firewall = Service iptables restart

Four: After the configuration is complete, it can be accessed in the external browser

1: View Native IP = = ifconfig

2: Access Address example: http://192.168.3.4:80

Note: The external project configuration to the directory name under the WebApps directory cannot have-such special characters, otherwise there will be a 404 case
