Question

我已经使用tomcat下载了liferay6包。我需要将liferay数据库更改为mysql数据库。我已经在google中搜索过，并且根据信息我已经使用以下代码行创建了portal-ext.properties。

jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost/lportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.default.username=root
jdbc.default.password=root123
jdbc.default.jndi.name=jdbc/LiferayPool
schema.run.enabled=true
schema.run.minimal=true

我修改了ROOT.xml.Now该文件中的代码是：

<Context path="" crossContext="true">

<Resource
    name="jdbc/LiferayPool"
    auth="Container"
    type="javax.sql.DataSource"
    driverClassName="com.mysql.jdbc.Driver"
    url="jdbc:mysql://localhost/lportal?useUnicode=true&amp;characterEncoding=UTF-8"
    username="root"
    password="root123"
    maxActive="20"
/> 
</Context>

我在mysql中创建了lportal数据库。我需要修改更多内容。如果我喜欢这样，我甚至无法看到liferay的默认登录页面。任何人都可以指出我在哪里做错了。谢谢。

如果我这样做，我会得到以下例外。

Answer 1

在portal-ext.properties文件中，如果指定JNDI名称进行查找就足够了。

jdbc.default.jndi.name=MyDataSource

在Tomcat的xml文件中，

<Resource
    name="MyDataSource"
    auth="Container"
    type="javax.sql.DataSource"
    driverClassName="com.mysql.jdbc.Driver"
    url="jdbc:mysql://localhost/lportal?useUnicode=true&amp;characterEncoding=UTF-8"
    username="root"
    password="root123"
    maxActive="20"
/>

确保您上面使用的用户（root）有权创建表。

另外，不要忘记重新启动Tomcat容器。

即使最重要的是，如果它不起作用，请在（bin）日志中共享例外。

Answer 2

1更新java连接器驱动程序

确保没有启动liferay门户！如果是，那就关闭。

下载并安装MySQL和HeidiSQL，你可以通过HeidiSql简单地创建mysql数据库。

从dev.mysql.com下载mysql.jar（Connector / J）您可能无法登录，只需在页面下方点击并点击链接：不，谢谢，只需开始下载。

在 liferay-portal-6.1.1-ce-ga2 \ tomcat-7.0.27 \ lib \ ext

中删除 mysql.jar

复制mysql-connector-java- 某些版本 -bin.jar in \ Program Files（x86）\ MySQL \ Connector J 文件夹和

将其粘贴到liferay-portal-6.1.1-ce-ga2 \ tomcat-7.0.27 \ lib \ ext中（不要忘记将其重命名为mysql.jar）

2-使用liferay控制面板 现在你可以启动liferay门户

了

在浏览器localhost中打开：8080 / 转到 - ＆gt;控制面板 - ＆gt;服务器管理 - ＆gt;数据迁移

JDBC驱动程序类名： com.mysql.jdbc.Driver

JDBC网址 JDBC：MySQL的：//本地主机：3306 / <强> DB-NAME 了useUnicode =真安培;的characterEncoding = UTF-8和; useFastDateParsing =假

DB-NAME - 您之前创建的数据库名称。

编写MySQL用户名和密码，然后单击下面的按钮。

现在在下一页中您可以看到 *红色边框 *中的一些文字，例如： 系统当前正在进行维护。请稍后再试。

没关系。等待..可能是半小时或更长时间，等待，并耐心等待））

当流程进行时，您可以执行下一步：

3-更改门户网站属性 在 liferay-portal-6.1.1-ce-ga2 \ tomcat-7.0.27 \ webapps \ ROOT \ WEB中打开文件 portal-ext.properties （如果不存在则创建它） -INF \ classes 并按照文字粘贴到此文件：

jdbc.default.driverClassName = com.mysql.jdbc.Driver

jdbc.default.url = jdbc：mysql：// localhost：这里必须是DB端口，默认情况下它是 3306 / * DB_NAME * 了useUnicode =真安培;？的characterEncoding = UTF-8和; useFastDateParsing =假

jdbc.default.username = MySQL用户的用户名

jdbc.default.password = MySQL用户密码

这就是
