去http://tomcat.apache.org/download-80.cgi下载Tomcat8的安装文件apache-tomcat-8.0.26.tar.gz。
将apache-tomcat-8.0.26.tar.gz文件放到/usr/local目录下，执行如下脚本：
# cd /usr/local
# tar -zxvf apache-tomcat-8.0.26.tar.gz // 解压压缩包
# rm -rf apache-tomcat-8.0.26.tar.gz.tar.gz // 删除压缩包
# mv apache-tomcat-8.0.26 tomcat
启动Tomcat8
# /usr/local/tomcat/bin/startup.sh //启动tomcat
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.8.0_60
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
如果出现下面错误：
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
则要注意提前设置java路径
在apache-tomcat-8.0.26/bin/setclasspath.sh中添加一下内容
export JAVA_HOME=/usr/java/jdk1.8.0_60
export JRE_HOME=/usr/java/jdk1.8.0_60/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
防火墙开放8080端口
增加8080端口到防火墙配置中，执行以下操作：
# vi /etc/sysconfig/iptables
#增加以下代码
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
重启防火墙
# service iptables restart
检验Tomcat8安装运行
通过以下地址查看tomcat是否运行正常：
http://192.168.11.52:8080/
看到tomcat系统界面，说明安装成功！
停止Tomcat8
# /usr/local/tomcat/bin/shutdown.sh //停止tomcat
