After uploading OK decompression 3.jdk

[root@localhost ~]# ls
anaconda-ks.cfg  jdk-8u201-linux-i586.tar.gz
[root@localhost ~]# tar xf jdk-8u201-linux-i586.tar.gz 
[root@localhost ~]# ls
anaconda-ks.cfg  jdk1.8.0_201  jdk-8u201-linux-i586.tar.gz
[root@localhost ~]# mkdir -p /usr/local/
bin/     etc/     games/   include/ lib/     lib64/   libexec/ sbin/    share/   src/     
[root@localhost ~]# mkdir /usr/local/java
[root@localhost ~]# mv jdk1.8.0_201/* /usr/local/java/

4.jdk environment variable configuration

[root@localhost ~]# vim /etc/profile #追加如下变量
export JAVA_HOME=/usr/local/java
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

6. Review the java version

[root@localhost local]# java -version
-bash: /usr/local/java/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: 没有那个文件或目录

Wrong: there is no prompt file.
This situation should be minimal installation system lacks the appropriate library file that caused the error
here can follow the prompts to install the appropriate library file
[root@localhost ~]# yum -y install ld-linux.so.2

[root@localhost ~]# java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) Client VM (build 25.201-b09, mixed mode)

[root@localhost ~]# mkdir /usr/local/tomcat8
[root@localhost ~]# mv apache-tomcat-8.5.41/* /usr/local/tomcat8/

9. Start tomcat

[root@localhost ~]# /usr/local/tomcat8/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat8
Using CATALINA_HOME:   /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Tomcat started.
[root@localhost ~]# ps -ef|grep java

10. Verify page

http://192.168.0.64:8080/

This firewall in the ON state, access is blocked to close the port through the firewall or page can allow.
Experimental environment can turn off the firewall:

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

Production environment is recommended to open the port and enhance server security:

[root@localhost tomcat8]# firewall-cmd --permanent --add-port=8080/tcp
success
[root@localhost tomcat8]# firewall-cmd --reload
success

Returning to the tomcat page displays OK.
