Tomcat默認發佈目錄
tomcat默認的程序發佈路徑爲tomcat/webapps/ROOT/下面。
例子：
（1）比如我在tomcat/webapps/ROOT/路徑下新建一個jsp文件，則可以直接通過URL爲：http://localhost:8080/index.jsp來訪問。
（2）再比如我做文件的上傳和下載功能時，可以在ROOT下新建一個FileUpload文件夾，把上傳文件的路徑設爲這個文件夾下，然後上傳一個文件test.txt做下載功能時，點擊該文件的下載按鈕，可以直接讓網頁打開一個URL：http://localhost:8080/index.jsp來訪問。
創建自己的發佈目錄，將發佈目錄下面東西全部刪除，創建ROOT發佈目錄：
[root@localhost webapps]# rm -rf *
[root@localhost webapps]# mkdir -p ROOT
來到ROOT目錄下
[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
每次刷新的時候時間都會變化，因爲這是一個動態的頁面，瞭解到這裏開始教你搭建jforum網站
搭建你的jforum網站
disscuz，wordpress是PHP開發的網站論壇包jforum是Java開發寫的包這個包.war結尾而不是.tar.gz結尾是因爲通過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
解壓包
[root@localhost ROOT]# /usr/java/jdk1.8.0_131/bin/jar -xvf jforum-2.5.0.war
[root@localhost ROOT]# ll
total 69908
drwxr-xr-x. 4 root root 68 Feb 5 2018 images

drwxr-xr-x. 2 root root 24 Feb 5 2018 tmp
drwxr-xr-x. 14 root root 174 Feb 3 2018 upgrade
drwxr-xr-x. 2 root root 24 Feb 5 2018 upload
drwxr-xr-x. 5 root root 87 Feb 5 2018 WEB-INF
[root@localhost ROOT]# /usr/local/tomcat/bin/shutdown.sh
[root@localhost ROOT]# /usr/local/tomcat/bin/startup.sh
搭建mysql並且創建數據庫
[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，再來到數據庫查看，看看也沒有數據
MariaDB [jforum]> show tables;
+-------------------------+
| Tables_in_jforum |

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 | |
+--------------+-------------+------+-----+---------+----------------+
至此搭建完畢，是不是很簡單？
