Overview
Apache tomcat is application server, as such is servers as a middle level between the client and the database system. The installation system is rather simple
Download release
Locate the most recent release, the current one is: 8.5.31 and I will install it on Centos 6.9(Final) - I like Centos 6 :) You can find it on the following location: https://tomcat.apache.org/download-80.cgi
Install Java
We have to firstly install Java and couple other things though:
[root@localhost jasper]# yum install java Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.coreix.net * extras: mirrors.coreix.net * updates: mirrors.coreix.net Resolving Dependencies --> Running transaction check ---> Package java-1.8.0-openjdk.x86_64 1:1.8.0.171-8.b10.el6_9 will be installed --> Processing Dependency: java-1.8.0-openjdk-headless = 1:1.8.0.171-8.b10.el6_9 for package: 1:java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x 86_64 --> Processing Dependency: xorg-x11-fonts-Type1 for package: 1:java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x86_64 --> Processing Dependency: libpng12.so.0(PNG12_0)(64bit) for package: 1:java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x86_64 --> Processing Dependency: libjvm.so(SUNWprivate_1.1)(64bit) for package: 1:java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x86_64 --> Processing Dependency: libjpeg.so.62(LIBJPEG_6.2)(64bit) for package: 1:java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x86_64 -------------------------------------- Installed: java-1.8.0-openjdk.x86_64 1:1.8.0.171-8.b10.el6_9 Dependency Installed: alsa-lib.x86_64 0:1.1.0-4.el6 fontconfig.x86_64 0:2.8.0-5.el6 freetype.x86_64 0:2.3.11-17.el6 giflib.x86_64 0:4.1.6-3.1.el6 java-1.8.0-openjdk-headless.x86_64 1:1.8.0.171-8.b10.el6_9 jpackage-utils.noarch 0:1.7.5-3.16.el6 libICE.x86_64 0:1.0.6-1.el6 libSM.x86_64 0:1.2.1-2.el6 libX11.x86_64 0:1.6.4-3.el6 libX11-common.noarch 0:1.6.4-3.el6 libXau.x86_64 0:1.0.6-4.el6 libXext.x86_64 0:1.3.3-1.el6 libXfont.x86_64 0:1.5.1-2.el6 libXi.x86_64 0:1.7.8-1.el6 libXrender.x86_64 0:0.9.10-1.el6 libXtst.x86_64 0:1.2.3-1.el6 libfontenc.x86_64 0:1.1.2-3.el6 libjpeg-turbo.x86_64 0:1.2.1-3.el6_5 libpng.x86_64 2:1.2.49-2.el6_7 libxcb.x86_64 0:1.12-4.el6 ttmkfdir.x86_64 0:3.0.9-32.1.el6 tzdata-java.noarch 0:2018e-3.el6 xorg-x11-font-utils.x86_64 1:7.2-11.el6 xorg-x11-fonts-Type1.noarch 0:7.2-11.el6 Complete!
Users & Directory Creation
Now we have to create the users and directory:
[root@localhost jasper]# groupadd tomcat [root@localhost jasper]# mkdir /opt/tomcat tomcat [root@localhost jasper]# useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
Tomcat Installation
Finally, we can download and install it :)
[root@localhost jasper]# cd /opt/tomcat [root@localhost opt]# wget http://www-us.apache.org/dist/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz --2018-06-20 15:53:28-- http://www-us.apache.org/dist/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz Resolving www-us.apache.org... 40.79.78.1 Connecting to www-us.apache.org|40.79.78.1|:80... connected.

Unzip the installation
[root@localhost opt]# tar -xzvf apache-tomcat-8.5.31.tar.gz apache-tomcat-8.5.31/conf/ apache-tomcat-8.5.31/conf/catalina.policy apache-tomcat-8.5.31/conf/catalina.properties apache-tomcat-8.5.31/conf/context.xml apache-tomcat-8.5.31/conf/jaspic-providers.xml apache-tomcat-8.5.31/conf/jaspic-providers.xsd apache-tomcat-8.5.31/conf/logging.properties apache-tomcat-8.5.31/conf/server.xml apache-tomcat-8.5.31/conf/tomcat-users.xml apache-tomcat-8.5.31/conf/tomcat-users.xsd apache-tomcat-8.5.31/conf/web.xml apache-tomcat-8.5.31/bin/ apache-tomcat-8.5.31/lib/ apache-tomcat-8.5.31/logs/ -------------------------------- [root@localhost opt]# ls -alrt [root@localhost apache-tomcat-8.5.31]# ls -alrt total 120 drwxr-x---. 2 root root 4096 Apr 27 22:24 work drwxr-x---. 2 root root 4096 Apr 27 22:24 logs drwxr-x---. 7 root root 4096 Apr 27 22:24 webapps -rw-r-----. 1 root root 16246 Apr 27 22:26 RUNNING.txt -rw-r-----. 1 root root 7138 Apr 27 22:26 RELEASE-NOTES -rw-r-----. 1 root root 1723 Apr 27 22:26 NOTICE -rw-r-----. 1 root root 57092 Apr 27 22:26 LICENSE drwx------. 2 root root 4096 Apr 27 22:26 conf drwxr-xr-x. 4 root root 4096 Jun 20 15:53 .. drwxr-xr-x. 9 root root 4096 Jun 20 15:53 . drwxr-x---. 2 root root 4096 Jun 20 15:53 lib drwxr-x---. 2 root root 4096 Jun 20 15:53 temp drwxr-x---. 2 root root 4096 Jun 20 15:53 bin
Change permissions
[root@localhost opt]# id tomcat uid=500(tomcat) gid=500(tomcat) groups=500(tomcat) [root@localhost tomcat]# chown -hR tomcat:tomcat tomcat [root@localhost tomcat]# ls -lart total 9348 -rw-r--r--. 1 root root 9552281 Apr 27 22:47 apache-tomcat-8.5.31.tar.gz dr-xr-xr-x. 22 root root 4096 Jun 20 15:00 .. drwxr-xr-x. 4 root root 4096 Jun 20 15:53 . drwxr-xr-x. 9 tomcat tomcat 4096 Jun 20 15:53 apache-tomcat-8.5.31
Start tomcat
Once the tomcat is unzipped with it's own owner, we can start it as follows:
[root@localhost bin]# ./startup.sh Using CATALINA_BASE: /opt/apache-tomcat-8.5.31 Using CATALINA_HOME: /opt/apache-tomcat-8.5.31 Using CATALINA_TMPDIR: /opt/apache-tomcat-8.5.31/temp Using JRE_HOME: /usr Using CLASSPATH: /opt/apache-tomcat-8.5.31/bin/bootstrap.jar:/opt/apache-tomcat-8.5.31/bin/tomcat-juli.jar Tomcat started.

Result
We can see the front page if we enter via http client:
