1. Before installing tomcat, make sure that jdk has been installed and configured on the linux machine
Enter in the command line: java -version command, as shown below, indicating that jdk has been installed
2. Create a new tomcat installation directory in the usr directory
The command is:
mkdir -p /usr/tomcat/
3. Copy or move apache-tomcat-9.0.2.tar.gz to the java directory (apache-tomcat-9.0.2.tar.gz is already in the /usr/local/tools/ directory of linux)
4. Unzip tomcat to the current directory
tar -zxvf apache-tomcat-9.0.2.tar.gz
Get the folder apache-tomcat-9.0.2
5. Add the tomcat environment variable:
Modify the application environment variables to make the configuration take effect:
6. Start the tomcat service:
Enter the bin directory:
start tomcat:
./startup.sh
7. If you cannot access the server address, it may be a problem with the server firewall. Port 8080 is blocked, so you need to open port 8080, save and restart the firewall:
[root@localhost bin]# iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
[root@localhost bin]# /etc/init.d/iptables save
[root@localhost bin]# /etc/init.d/iptables restart
Re-visit the server tomcat address to access:
8. Configure tomcat account password permissions (login using the Web management interface)
Modify the configuration file tomcat-users.xml under tomcat
Add the following code:
Note: username and password are the account passwords required to log in to the tomcat management interface.
9. Tomcat configuration service:
New script:
Addition script content:
#!/bin/bash
# dcription: Tomcat9 Start Stop Restart
# processname: tomcat9
# chkconfig: 234 20 80
CATALINA_HOME=/usr/tomcat/apache-tomcat-9.0.2
case $1 in
start)
echo "Starting Tomcat..."
sh $CATALINA_HOME/bin/startup.sh
;;
stop)
echo "Stopping Tomcat..."
sh $CATALINA_HOME/bin/shutdown.sh
;;
restart)
echo "Stopping Tomcat..."
sh $CATALINA_HOME/bin/shutdown.sh
sleep 2
echo
echo "Starting Tomcat..."
sh $CATALINA_HOME/bin/startup.sh
;;
*)
echo 'please use : tomcat {start | stop | restart}'
;;
esac
exit 0
Execute scripts to start, stop and restart services.
Start: service tomcat start
Stop: service tomcat stop
Restart: service tomcat restart
When the above error is reported when the script is executed, catalina.sh and .bashrc can be executed successfully by adding the following content
Enter the bin directory of tomcat, edit the catalina.sh file, and add the following content:
export JAVA_HOME=/usr/tomcat/apache-tomcat-9.0.2 export JRE_HOME=/usr/tomcat/apache-tomcat-9.0.2/jre
Edit the .bashrc file and add the following:
set JAVA_HOME=/usr/java/jdk1.8.0_152
export JAVA_HOME
set PATH=$JAVA_HOME/bin:$PATH
export PATH
set CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export CLASSPATH
10. Tomcat configuration starts automatically when booting:
Add management of tomcat service to chkconfig:
[root@localhost ~]# chkconfig --add tomcat
Set the tomcat service to start automatically:
[root@localhost ~]# chkconfig tomcat on
View the startup status of tomcat;
[root@localhost ~]# chkconfig --list | grep tomcat
Close the tomcat service from starting:
[root@localhost ~]# chkconfig tomcat off
Delete the management of the tomcat service on chkconfig:
[root@localhost ~]# chkconfig --del tomcat
