Tomcat 數據庫連接池配置(各種版本) (轉)

Tomcat 數據庫連接池配置

前言 :

? 1? 準備 mysql 的 jdbc 驅動程序

? 2? 安裝 Tomcat 默認全部裝在 D:\Server\tomcat5.0 D:\Server\tomcat5.5 D:\Server\tomcat6.0

? 3? 以 TOMCAT_HOME 代替個版本的安裝目錄

4???????? 將 jdbc 驅動放入 TOMCAT_HOME\ common\lib\ 下面

5???????? 如果是其他數據庫的話，就是換一下 jdbc 驅動以及各種參數就可以了的

6???????? 配置 tomcat 數據源時的各種參數的詳細介紹

7???????? 其他設置。

1.?????? Tomcat 4.0

待添加

2.?????? Tomcat 5.0

2.1??? 建一個虛擬目錄 test? (TOMCAT_HOME\webapps\)

? 可以通過 http://localhost:8080/test 訪問你的網站了

2.2??? 配置 Context ( 在 TOMCAT_HOME\conf\Catalina\localhost\ 下 建 test.xm,)

test.xml:

<?xml version="1.0" encoding="utf-8"?>

<Context docBase="dbpool" path="/test" workDir="work\Catalina\localhost\test">

</Context>

2.3??? 配置 server.xml

server.xml? 的內容 : 紅色表示加入的 ( 或者通過 http://localhost:8080/admin 進行可視化配置 )
