We also create a directory called "/u01" to hold all the config, and make sure that it owned by the new "tomcat" user.# useradd tomcat# mkdir -p /u01# chown tomcat:tomcat /u01Install the JDK from the tarball under the "/u01/java" directory. We unzip it to create a new directory, which includes the version number, but use a symbolic link so we can always use the same path for the JAVA_HOME environment variable, regardless of the version.# su - tomcat$ mkdir -p /u01/java$ cd /u01/java$ tar xzf OpenJDK11U-jdk_x64_linux_hotspot_11.0.10_9.tar.gz$ ln -s jdk-11.0.10+9 latestInstall Tomcat from the tarball under the "/u01/tomcat" directory. We unzip it to create a new directory, which includes the version number, but use a symbolic link so we can always use the same path for the CATALINA_HOME environment variable, regardless of the version.$ mkdir -p /u01/tomcat$ cd /u01/tomcat$ tar xzf /tmp/apache-tomcat-9.0.45.tar.gz$ ln -s apache-tomcat-9.0.45 latestWe want to separate the config from the binaries, to make future upgrades easier, so we will create a new directory to act as the CATALINA_BASE location, and seed it by copying the relevant directories to the new directory. We are using a sub-directory called "instance1" to allow for multiple instances, but that is not necessary if you only plan to have a single Tomcat instance running.$ mkdir -p /u01/config/instance1$ cp -r /u01/tomcat/latest/conf /u01/config/instance1/$ cp -r /u01/tomcat/latest/logs /u01/config/instance1/$ cp -r /u01/tomcat/latest/temp /u01/config/instance1/$ cp -r /u01/tomcat/latest/webapps /u01/config/instance1/$ cp -r /u01/tomcat/latest/work /u01/config/instance1/Set the following environment variables and append them to the "/home/tomcat/.bash_profile" so they are set for subsequent logins.export JAVA_HOME=/u01/java/latestexport CATALINA_HOME=/u01/tomcat/latestexport CATALINA_BASE=/u01/config/instance1Start and stop Tomcat using the following scripts.$ $CATALINA_HOME/bin/startup.sh$ $CATALINA_HOME/bin/shutdown.shThe Tomcat logs are written
