CentOS下安装Tomcat 8

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
