tomcat默认的程序发布路径为tomcat/webapps/ROOT/下面。 例子： （1）比如我在tomcat/webapps/ROOT/路径下新建一个jsp文件，则可以直接通过URL为：http://localhost:8080/index.jsp来访问。 （2）再比如我做文件的上传和下载功能时，可以在ROOT下新建一个FileUpload文件夹，把上传文件的路径设为这个文件夹下，然后上传一个文件test.txt做下载功能时，点击该文件的下载按钮，可以直接让网页打开一个URL：http://localhost:8080/index.jsp来访问。
创建自己的发布目录，将发布目录下面东西全部删除，创建ROOT发布目录：
[root@localhost webapps]# rm -rf * [root@localhost webapps]# mkdir -p ROOT 来到ROOT目录下 [root@localhost webapps]# vim index.jsp [root@localhost webapps]# cat index.jsp <html> <body> <h1>JSP Test Page</h1> <%=new java.util.Date()%> </body> </html> [root@localhost webapps]# /usr/local/tomcat/bin/shutdown.sh [root@localhost webapps]# /usr/local/tomcat/bin/startup.sh每次刷新的时候时间都会变化，因为这是一个动态的页面，了解到这里开始教你搭建jforum网站
disscuz，wordpress是PHP开发的网站论坛包jforum是Java开发写的包这个包.war结尾而不是.tar.gz结尾是因为通过Java的jar工具打包的
[root@localhost ~]# ll /usr/java/jdk1.8.0_131/bin/jar -rwxr-xr-x. 1 10 143 7925 Mar 15 2017 /usr/java/jdk1.8.0_131/bin/jar [root@localhost ~]# ll jforum-2.5.0.war -rw-r--r--. 1 root root 71557435 May 1 07:08 jforum-2.5.0.war解压包

[root@localhost ROOT]# yum install mariadb mariadb-devel mariadb-server -y [root@localhost ROOT]# systemctl start mariadb MariaDB [(none)]> create database jforum charset=utf8; MariaDB [(none)]> grant all on jforum.* to 'jforum'@'192.168.179.%' identified by '123456'; MariaDB [(none)]> flush privileges;搭建完成，再来到数据库查看，看看也没有数据
MariaDB [jforum]> show tables; +-------------------------+ | Tables_in_jforum | +-------------------------+ | jforum_api | | jforum_attach | | jforum_attach_desc | | jforum_attach_quota | | jforum_banlist | | jforum_banner | | jforum_bookmarks | | jforum_categories | | jforum_config | | jforum_extension_groups | | jforum_extensions | | jforum_forums | | jforum_forums_watch | | jforum_groups | | jforum_karma | | jforum_mail_integration | | jforum_moderation_log | | jforum_posts | | jforum_posts_text | | jforum_privmsgs | | jforum_privmsgs_text | | jforum_quota_limit | | jforum_ranks | | jforum_role_values | | jforum_roles | | jforum_sessions | | jforum_smilies | | jforum_spam | | jforum_topics | | jforum_topics_watch | | jforum_user_groups | | jforum_users | | jforum_vote_desc | | jforum_vote_results | | jforum_vote_voters | | jforum_words | +-------------------------+ 36 rows in set (0.00 sec) MariaDB [jforum]> desc jforum_api; +--------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+-------------+------+-----+---------+----------------+ | api_id | int(11) | NO | PRI | NULL | auto_increment | | api_key | varchar(32) | NO | | NULL | | | api_validity | datetime | NO | | NULL | | +--------------+-------------+------+-----+---------+----------------+至此搭建完毕，是不是很简单？
