先把tomcat和jdk包下好

http://tomcat.apache.org/download-70.cgi

http://www.Oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

安装jdk

[root@kurolz ~]# ls jdk*
jdk-8u131-linux-x64.rpm
[root@kurolz ~]# rpm -ivh jdk-8u131-linux-x64.rpm

配置环境变量

[root@kurolz ~]# vim /etc/profile
export JAVA_HOME=/usr/java/default
export JAVA_BIN=$JAVA_HOME/bin
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
[root@kurolz ~]# source /etc/profile
[root@kurolz ~]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

解压安装tomcat

[root@kurolz ~]# tar -zxvf apache-tomcat-7.0.77.tar.gz
[root@kurolz ~]# cd apache-tomcat-7.0.77[root@kurolz ~]# cd apache-tomcat-7.0.77/bin/
[root@kurolz bin]# ./startup.sh
Using CATALINA_BASE:   /root/apache-tomcat-7.0.77
Using CATALINA_HOME:   /root/apache-tomcat-7.0.77
Using CATALINA_TMPDIR: /root/apache-tomcat-7.0.77/temp
Using JRE_HOME:        /usr/java/default
Using CLASSPATH:       /root/apache-tomcat-7.0.77/bin/bootstrap.jar:/root/apache-tomcat-7.0.77/bin/tomcat-juli.jar
Tomcat started.

关闭防火墙或者加一条允许8080端口通过

/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT

[root@kurolz bin]# service iptables stop
iptables：清除防火墙规则：                             [确定]
iptables：将链设置为政策 ACCEPT：filter                    [确定]
iptables：正在卸载模块：                              [确定]

浏览器测试：http://ip:8080

增加web管理账号和角色，再<tomcat-users>标签里写入下面2条,指定

[root@kurolz ~]# vim apache-tomcat-7.0.77/conf/tomcat-users.xml
<tomcat-users><role rolename="kurolz"/><user username="kurolz" password="kurolz" role="kurolz"/>
</tomcat-users>
