Preface

A memo when building Tomcat, which everyone loves as a Java application server, on CentOS 7 without yum. Unless you have a specific reason, I think it's faster to use yum.

Premise

Assuming CentOS 7.3
Use Oracle's original JDK instead of OpenJDK
tomcat is not installed via yum, but installed individually from the archive dropped from the official

Construction work

Preparation

Added tomcat user (username can be anything but easy to understand)

[root@localhost ]# useradd tomcat
[root@localhost ]# passwd tomcat

Java installation

Download the JDK rpm from the URL below http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

It is difficult to bring it with wget / curl because it is necessary to press agree.

Bring the dropped .rpm to the target server

In my case, I dropped it on my PC and brought it to the target server by sftp.

[root@localhost ]# yum localinstall jdk-8u111-linux-x64.rpm
#root and tomcat.bash_export to profile JAVA_HOME=/usr/Java/jdk1.8.0_111/jre/Added

tomcat installation

Drop the binary from tomcat official and unzip => change owner / group In the example below, it is placed in / opt, but you can use any path you like.

[root@localhost ]# wget http://ftp.jaist.ac.jp/pub/apache/tomcat/tomcat-8/v8.5.6/bin/apache-tomcat-8.0.39.tar.gz
[root@localhost ]# tar xzvf apache-tomcat-8.0.39.tar.gz
[root@localhost ]# mv apache-tomcat-8.0.39 /opt/tomcat
[root@localhost ]# cd /opt/
[root@localhost ]# chown -R tomcat:tomcat tomcat

Service registration to systemd

You need to manually create / register this area, which yum will do automatically.

[root@localhost ]# vim /etc/systemd/system/tomcat.service

[Unit]
Description=Apache Tomcat 8
After=network.target

[Service]
User=tomcat
Type=forking
EnvironmentFile=/etc/sysconfig/tomcat
KillMode=none
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh

[Install]
WantedBy=multi-user.target



[root@localhost ]# vim /etc/sysconfig/tomcat

Java_HOME="/usr/Java/jdk1.8.0_111/jre/"
Java_OPTS="-DJava.security.egd=file:/dev/./urandom"

[root@localhost ]# systemctl daemon-reload

Registering a new service for firewalld (optional)

If you do not use firewalld for verification purposes, skip it and OK

[root@localhost ]# vim /usr/lib/firewalld/services/tomcat.xml

<service>
  <short>WWW (HTTP-tomcat)</short>
  <description>HTTP is the protocol used to serve Web pages. If you plan to make your Web server publicly available, enable this option. This option is not required for viewing pages locally or developing Web pages.</description>
  <port protocol="tcp" port="8080"/>
</service>

[root@localhost ]# systemctl restart firewalld
[root@localhost ]# firewall-cmd --add-service=tomcat --zone=public --permanent
success
[root@localhost ]# systemctl restart firewalld

Operation check

First, start Tomcat. Also, make sure that the service starts automatically when the OS starts.

[root@localhost ]# systemctl enable tomcat
[root@localhost ]# systemctl start tomcat
[root@localhost ]# systemctl status tomcat
[root@localhost ]# ss -nat | grep 8080
LISTEN     0      100                      :::8080                    :::*

Access http: // [ip_addr]: 8080 with a web browser, and when the familiar tomcat top page is displayed, it's OK.
