Procedure to download & install Tomcat 7 on Linux environment

Tomcat installation is one of the most straightforward installations I have come across.

However, if you don’t know then don’t worry. You will learn how to install Tomcat 7 and get up and running in just 5 minutes.

In this article, I will explain how to download, install and ensure it’s up & running.

• Download the latest Tomcat7 version 7.0.62 from below link

• Transfer the downloaded zip file to your server where you wish to install tomcat.

In this example – I have transferred to /opt/

• unzip the transferred file apache-tomcat-7.0.62.zip

And then you will have a new folder

You may rename apache-tomcat-7.0.62 to tomcat but it’s entirely on you. This concluded tomcat installation is done and now will start to ensure installation is successful.

• Go to apache-tomcat-7.0.62/bin folder
• Execute startup.sh to start the tomcat

If you are getting permission denied while executing sh file then you need to change the permission to sh file as executable.

Установка и базовая настройка Tomcat на Linux Ubuntu Server

Tomcat на Ubuntu не устанавливается из репозитория (в отличие от некоторых других дистрибутивов Linux, например, CentOS). Поэтому в данной инструкции мы выполним ручную установку — развертывание дополнительных компонентов (Java), загрузку и распаковку пакета веб-сервера Tomcat, а также настройку его автоматического запуска в случае сбоя или после перезагрузки системы. На момент обновления инструкции использовался Tomcat версии 10 и Ubuntu 20.04.

Подготовка системы

Обновляем список пакетов в репозиториях:

Задаем имя серверу:

hostnamectl set-hostname server.dmosk.ru

* в данном примере мы зададим имя server.dmosk.ru.

Настраиваем часовой пояс, например:

timedatectl set-timezone Europe/Moscow

* где Europe/Moscow — московское время. Список всех возможных зон смотрим командой timedatectl list-timezones.

Устанавливаем сервис для автоматической синхронизации времени, а также разрешаем его автозапуск:

apt-get install chrony

systemctl enable chrony

Если мы используем брандмауэр, необходимо открыть порт 8080:

iptables -A INPUT -p tcp —dport 8080 -j ACCEPT

* 8080 — порт по умолчанию, на котором работает Tomcat. Если мы заходим поменять данный порт, то нужно будет открыть именно его.

Сохраняем правила — для этого устанавливаем утилиту iptables-persistent:

apt-get install iptables-persistent

Если в процессе установки мы отказались сохранять правила, выполняем команду:

Можно приступать к установке Java.

Подготовка к установке

Для работы веб-сервера нам необходимы Java и пользователь, под которым будет работать Tomcat.

Установка JAVA

Мы установим пакет openjdk. Для этого вводим команду:

apt-get install default-jdk

* будет установлена последняя версия, максимально совместимая с используемой версией операционной системы Ubuntu.

Если в системе окажется несколько версий java, выберем последнюю. Для этого вводим команду:

update-alternatives —config java

. и выбираем в списке соответствующий вариант.

Проверяем используемую версию java:

Мы должны увидеть что-то на подобие:

openjdk version «14.0.2» 2020-07-14
OpenJDK Runtime Environment (build 14.0.2+12-Ubuntu-120.04)
OpenJDK 64-Bit Server VM (build 14.0.2+12-Ubuntu-120.04, mixed mode, sharing)

Создание пользователя

Создаем пользователя командой:

useradd tomcat -U -s /bin/false -d /opt/tomcat -m

* в итоге будет создан пользователь tomcat со следующими опциями:

• -U — также будет создана группа с таким же именем, что и пользователь.
• -s /bin/false — запрещает пользователю интерактивный вход в систему.
• -d /opt/tomcat — указывает путь до домашней директории пользователя.
• -m — сразу создает домашнюю директорию пользователю.

Можно приступать к установке веб-сервера Apache Tomcat.

Установка Tomcat

Переходим на страницу официального сайта веб-сервера. В меню слева выбираем необходимую версию Tomcat:

* на момент обновления статьи, последняя версия была 10.

Копируем ссылку на архив tar.gz:

Используя скопированную ссылку, скачиваем архив на наш сервер:

Распаковываем содержимое архива в каталог /opt/tomcat:

tar zxvf apache-tomcat-*.tar.gz -C /opt/tomcat —strip-components 1

Готово. Можно запустить сервер командой:

Открываем браузер и переходим на страницу http:// :8080 — мы должны увидеть стартовую страницу Tomcat:

Наш сервер работает.

Посмотреть версию установленного программного обеспечения можно командой:

java -cp /opt/tomcat/lib/catalina.jar org.apache.catalina.util.ServerInfo

Мы должны увидеть что-то на подобие:

Server version: Apache Tomcat/10.0.2
Server built: Jan 28 2021 18:48:46 UTC
Server number: 10.0.2.0
OS Name: Linux
OS Version: 5.4.0-26-generic
Architecture: amd64
JVM Version: 14.0.2+12-Ubuntu-120.04
JVM Vendor: Private Build

Настройка автозапуска

Мы выполнили разовый запуск нашего веб-сервера, но, когда будет перезагружен компьютер, он не запустится. Чтобы это исправить, мы создадим юнит в systemd.

Для начала, остановим работу Tomcat:

Поменяем владельца для всех файлов в каталоге /opt/tomcat:

chown -R tomcat:tomcat /opt/tomcat

Создадим конфигурационный файл для нового юнита:

[Unit]
Description=Apache Tomcat Server
After=network.target

[Service]
Type=forking
User=tomcat
Group=tomcat
Environment=»JAVA_HOME=/usr/lib/jvm/default-java»
Environment=»JAVA_OPTS=-Djava.security.egd=file:///dev/urandom -Djava.awt.headless=true»
Environment=»CATALINA_BASE=/opt/tomcat»
Environment=»CATALINA_HOME=/opt/tomcat»
Environment=»CATALINA_PID=/opt/tomcat/temp/tomcat.pid»
Environment=»CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC»
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh
Restart=on-failure
RestartSec=10

* где обращаем внимание на:

• User/Group — пользователь и группа пользователя, от чьего имени будет работать сервис.
• Environment — переменные окружения. В нашем примере задается несколько для нормальной работы Java и Tomcat.
• ExecStart/ExecStop — пути к скриптам, которые запускают или останавливают работу службы веб-сервера.
• Restart/RestartSec — задают поведение сервиса при необходимости выполнить перезапуск. В нашем примере выполнять при сбое с интервалом в 10 секунд.

Из данных опций, возможно вам захочется поменять CATALINA_OPTS, например, задать другие значения для выделения памяти или указать определенный порт. Остальные опции можно оставить.

Перечитываем новый конфигурационный файл в systemd:

How to Install Tomcat 7 Server on Ubuntu, Debian and LinuxMint

Apache Tomcat is a opensource webserver product of Apache Foundation like Apache HTTP server. It is used for deploying Java Servlet and JSP applications. To deploy an application in Tomcat we can simply create a war file and deploy them. For more details about you can visit apache official site http://tomcat.apache.org/ .

This article will help you to install tomcat 7 on Ubuntu, Debian and LinuxMint systems.

Step 1 – Verify JAVA

First, we need to make sure that we have installed java on or system. JAVA is the first requirement of tomcat installation. Use the following command to check if you have java installed already on your system. Try to keep java up to date with the latest version.

In case you do not have java installed use link: Install JAVA 8 on Ubuntu

Step 2 – Download Tomcat 7 Archive

After configuring JAVA properly on your system, let’s download Apache tomcat archive file from Apache official site using http://tomcat.apache.org/download-70.cgi or use the following command to download Tomcat 7.0.68 from Apache server.

After competed download extract archive file in /opt directory. You may change this location as per your setup.

Step 3 – Setup Environment Variable

Before starting Tomcat, Configure environment variables by adding an entry in the

/.bashrc file, So that the system environment can set on system bootup with the following command.

Step 4 – Start Tomcat

After completing all the above configuration, Let’s use the below command to start Tomcat. There is no need to compile its source. Tomcat by default start on port 8080, So make sure no other application using the same port.

Step 5 – Access Tomcat

Tomcat server works on port 8080 default. Access tomcat on a web browser by connecting your server on port 8080.

Step 6 – Setup User Accounts

Finally we need to create user accounts to secure and access admin/manager pages. Edit conf/tomcat-users.xml file in your editor and paste inside tags.

Step 7 – Create Tomcat7 Init Script

Create a init file /etc/init.d/tomcat7 using following content.

Now execute following commands to set proper permissions and symbolic links for init script.
