环境描述：
centos7最小安装，配置tomcat8
1.可用本地电脑下载jdk1.8
2.安装上传工具
[root@localhost ~]# yum -y install lrzsz
上传jdk
[root@localhost ~]# rz
3.jdk上传OK后解压
[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环境变量配置
[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
export PATH=$PATH:$JAVA_HOME/bin
5.更新profile文件
[root@localhost ~]# source /etc/profile
6.查看java版本
[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
出错了：提示没有文件。
此情况应该是最小安装系统缺少相应的库文件导致出错
这里可根据提示安装相应的库文件即可
[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 ~]# javac -version
javac 1.8.0_201
安装完提示缺少的文件后，再次查看Java版本，OK。
7.下载tomcat8
8.上传tomcat8并解压
[root@localhost ~]# rz
[root@localhost ~]# ls
anaconda-ks.cfg apache-tomcat-8.5.41.tar.gz jdk1.8.0_201 jdk-8u201-linux-i586.tar.gz
[root@localhost ~]# tar xf apache-tomcat-8.5.41.tar.gz
[root@localhost ~]# ls
anaconda-ks.cfg apache-tomcat-8.5.41 apache-tomcat-8.5.41.tar.gz jdk1.8.0_201 jdk-8u201-linux-i586.tar.gz
[root@localhost ~]# mkdir /usr/local/tomcat8
[root@localhost ~]# mv apache-tomcat-8.5.41/* /usr/local/tomcat8/
9.启动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
root 9744 1 31 16:44 pts/0 00:00:03 /usr/local/java/bin/java -Djava.util.logging.config.file=/usr/local/tomcat8/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dorg.apache.catalina.security.SecurityListener.UMASK=0027 -Dignore.endorsed.dirs= -classpath /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat8 -Dcatalina.home=/usr/local/tomcat8 -Djava.io.tmpdir=/usr/local/tomcat8/temp org.apache.catalina.startup.Bootstrap start
root 9787 7172 0 16:44 pts/0 00:00:00 grep --color=auto java
启动完成，查看进程OK。
10.页面验证
http://192.168.0.64:8080/
此为防火墙在开启状态，访问被阻，关闭防火墙或者允许页面端口通过都可以。
实验环境可关闭防火墙：
[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.
生产环境建议开启端口即可，增强服务器安全性：
[root@localhost tomcat8]# firewall-cmd --permanent --add-port=8080/tcp
success
[root@localhost tomcat8]# firewall-cmd --reload
success
久违的tomcat页面显示OK。
