Tomcat实现基于域名的多虚拟主机

IT知识虚拟基于域名

【Tomcat实现基于域名的多虚拟主机】努力尽今夕，少年犹可夸。这篇文章主要讲述Tomcat实现基于域名的多虚拟主机相关的知识，希望能为你提供帮助。


1.基础环境准备

# 主机上完成JDK 和 tomcat 安装，完成基础环境的准备

install_tomcat

[root@Tomcat-HostsIP48 ]#bash install_tomcat2022.sh

2.修改Tomcat的配置文件，实现基于主机头的虚拟主机基本内容：修改Tomcat的配置文件，实现 w1.shone.cn和 w2.shone.cn 基于主机头的两个虚拟主机。准备两个虚拟主机的网站目录及网页文件。
# 默认的 tomcat/usr/local/tomcat/conf/server.xml配置信息
[root@Tomcat-HostsIP48 ]#vim /usr/local/tomcat/conf/server.xml
