1： 安装jdk tomcat后 能访问tomcat成功
2：注意要在防火墙开启你的tomcat开启的端口号（操作如下）
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
添加完毕 。 source/etc/sysconfig/iptables 使修改的文件生效
3：在/etc/rc.local 目录下加入以下信息
（可以覆盖，要改你的toncat和jdk的安装路径
#!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. export JAVA_HOME=/opt/jdk1.8.0_101 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin export CATALINA_HOME=/opt/apache-tomcat-8.5.4 #tomcat自启动 /opt/apache-tomcat-8.5.4/bin/startup.sh touch /var/lock/subsys/local
4：重启系统、tomcat已经开机启动成功
或者 直接在rc.local最下面增加两行代码、依旧可以开机重启
export JAVA_HOME=/opt/jdk1.8.0_101 ---JDK路径 /opt/software/apache-tomcat-8.5.4/bin/startup.sh start --- tomcat启动命令
