安装tomcat

#安装JDK
[root@localhost ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel

#安装tomcat
[root@localhost ~]# wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz
[root@localhost ~]# tar xf apache-tomcat-9.0.37.tar.gz
[root@localhost ~]# mv apache-tomcat-9.0.37 /usr/local/tomcat

#启动tomcat

修改配置文件

修改apache的httpd.conf配置文件，取消如下两行的注释：

#LoadModule proxy_http_module modules/mod_proxy_http.so
#LoadModule proxy_module modules/mod_proxy.so

//启用httpd的相关模块
[root@localhost ~]# vim /etc/httpd24/httpd.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

//配置虚拟主机
[root@localhost ~]# vim /etc/httpd24/httpd.conf
#在最后添加
<VirtualHost *:80>
    DocumentRoot "/usr/local/apache/htdocs"
    ProxyPass / http://192.168.32.125:8080/
    ProxyPassReverse / http://192.158.32.125:8080/
    <Directory "/usr/local/apache/htdocs">
        Options none
        AllowOverride none
        Require all granted
    </Directory>
</VirtualHost>

把所有http的请求代理到 http://192.168.32.125:8080/ ，也就是 Tomcat 的访问地址，
可以加如 ProxyPass /images !  表示除了images目录之外不转发，可以实现静态内容不转给tomcat

#重启apache
[root@localhost ~]# apachectl restart
[root@localhost ~]# ss -tanl

LISTEN     0      128           [::]:22                        [::]:*

访问80端口时，转到了8080
