lsof-i:8082 to see if the port is occupied

Ps-ef |grep 8082

Ps-ef|grep Tomcat

Linux under Tomcat configuration

20. Download The Tomcat compression Pack and place Linux under the

Apache-tomcat-7.0.tar.gz

Use FTP to place under Linux

21st. Unzip Unzip

TAR-ZXVF apache-tomcat-7.0.tar.gz/usr/local

Create a soft connection for version upgrade

Ln-s/usr/local/apache-tomcat-7.0/usr/local/tomcat

tar-zcvf/home/file.tar.gz file
package file file to generate home directory file.tar.gz)

Set Permissions

chmod +x/usr/local/tomcat

22. Configuring environment Variables

Vi/etc/profile

Export Tomcat_home=/usr/loacl/tomcat

Export Catalina_home=/usr/local/tomcat

Save and exit

: Wq

Source/etc/profile

23. Tomcat Directory

Enable Tomcat sh startup.sh or sh/usr/local/tomcat/bin/startup.sh

Tomcat Directory

Bin Storage launches a script to close Tomcat

Conf store different configuration files Server.xml Web. XML (port, IP)

Doc Storage Documentation

Lib holds the library file jar required for Tomcat operation

Logs storing the log file for Tomcat execution

SRC store Tomcat's source code

WebApps Tomcat's main Web publishing directory

Work stores the class file generated by the JSP compilation

24. Modify Configuration Modify Port

Cd/usr/local/apache-tomcat-7.0/conf

ll

VI server.xml(tomcat server boot port)

Connector port= "" Protocol= "http/1.1"

conectiontimeout= "20000"

: Wq(save exit)

Add the specified port to the firewall (/sbin/iptables)

Iptables-i input-p Protocol --dport port number -j ACCEPT

such as: iptables-i input-p tcp--dport 8080-j ACCEPT

Service Iptables Save

Service Iptables Restart

or directly modify the file /etc/sysconfig/iptables

Vi/etc/sysconfig/iptables

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

Servic iptables Restart

In the browser input HTTP://IP: port to see if it can be opened

modifying character settings UTF-8

Cd/usr/local/apache-tomcat-7.0/conf/server.xml

connectiontimeout= "20000"

Redirectport= "8443"

uriencoding= "UTF-8"/>

join the mysql connection pack

Tomcat under the Lib

Modify catalina.sh

The web system is larger to add Tomcat memory

Cat catalina.sh

Java_opts= "-server-xms1024m-xmx2048m-xx:permsize=128m-xx:maxnewsize=512m-xx:maxpermsize=256m- Djava.awt.headless=true "

VI catalilna.sh

25. start Tomcat

Go to the Bin directory to execute the./startup.sh boot

CD bin

./startup.sh

Enter logs to see if it has started normally

CD Logs/catalina.out

(Starting .... Server can access the console to see information)

26. To see if the port is occupied

lsof-i:8082

Java 2463 Root will appear ...

View by Process number

PS Axu|grep 2463 viewing process specific information

Shut down the Tomcat server./shutdown.sh

27. Configure Web Admin Account

Vi/usr/local/apache-tomcat-7.0/conf/tomcat-users.xml

28. set up tomcat boot up

/etc/rc.d/init.d to add Tomcat to start the file
