Tomcat 自定义默认网站目录

上面访问的网址为http://192.168.0.108:8080/memtest/meminfo.jsp 
需求：

现在我想访问格式为http://192.168.0.108:8080/meminfo.jsp

方法一

将meminfo.jsp或其他程序放在tomcat/webapps/ROOT目录下即可。因为默认网站根目录为tomcat/webapps/ROOT

[root@mysql webapps]# cd memtest
[root@mysql memtest]# pwd
/usr/local/tomcat/webapps/memtest
[root@mysql memtest]# cp 
meminfo.jsp  META-INF/    
[root@mysql memtest]# cp meminfo.jsp ../ROOT/

方法二

vim /usr/local/tomcat/conf/server.xml

加上docBase=绝对路径

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
         <Context path="" docBase="/usr/local/tomcat/webapps/memtest" debug="0" reloadable="false" crossContext="true"/>

 重启tomcat

[root@mysql ROOT]# /usr/local/tomcat/bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/java/jdk1.8
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@mysql ROOT]# /usr/local/tomcat/bin/startup.sh

Tomcat started.
