Java开源Blog实现，Roller 2.0 的安装手记！

Roller 是一个Struts + Hibernate 的 Java 开源实现，正好拿来研究研究，首先就是要把它安装起来了，整理

了一下步骤和注意事项，记录如下：

准备需要的基本环境：

1.Java 2 SDK 1.4.2_10

2.Tomcat 5.0.28

3.Roller 2.0

4.MySQL 5.0.16

首先，确保MySQL开启了对InnoDB和UTF-8的支持，在my.ini中开启下面的参数：

[mysqld]

default-storage-engine=innodb

default-character-set=utf8

启动好MySQL待用...D:\MySQL\mysqld.exe --console --datadir=I:\MyData\Data

假设我的Tomcat主目录为：$CATALINA_HOME=D:\J2EE_HOME\AppServer\Tomcat

把压缩的Roller文件 roller-2.0-incubating.tar 解开...

并放到$CATALINA_HOME\WebApp\roller下面...如图...

开始建立MySQL中的数据库：

I:> CD %CATALINA_HOME%\webapps\roller\WEB-INF\dbscripts\mysql

I:> mysql -u root -p

password: *****

mysql> create database roller;

mysql> grant all on roller.* to scott@‘%‘ identified by ‘tiger‘;

mysql> grant all on roller.* to scott@‘localhost‘ identified by ‘tiger‘;

mysql> use roller;

mysql> source createdb.sql

mysql> quit

在 $CATALINA_HOME\conf\Catalina\localhost 中放置Roller的Web Application的部署

配置档案 roller.xml，内容如下：

<Context path="/roller" docBase="${catalina.home}/webapps/roller" debug="0"><Realm className="org.apache.catalina.realm.JDBCRealm"

driverName="com.mysql.jdbc.Driver"

connectionURL="jdbc:mysql://localhost:3306/roller?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf-8&amp;mysqlEncoding=utf8"

connectionName="scott"

connectionPassword="tiger"

userTable="rolleruser"

userNameCol="username"

userCredCol="passphrase"

userRoleTable="userrole"

roleNameCol="rolename" debug="0" />

<Resource name="jdbc/rollerdb" auth="Container" type="javax.sql.DataSource" />

<ResourceParams name="jdbc/rollerdb">

<parameter>

<name>factory</name>

<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>

</parameter>

<parameter>

<name>driverClassName</name>

<value>com.mysql.jdbc.Driver</value>

</parameter>

<parameter>

<name>url</name>

<value>jdbc:mysql://localhost:3306/roller?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf-8&amp;mysqlEncoding=utf8</value>

</parameter>

<parameter>

<name>username</name>

<value>scott</value>

</parameter>

<parameter>

<name>password</name>

<value>tiger</value>

</parameter>

<parameter>

<name>maxActive</name>

<value>20</value>

</parameter>

<parameter>

<name>maxIdle</name>

<value>3</value>

</parameter>

<parameter>

<name>removeAbandoned</name>

<value>true</value>

</parameter>

<parameter>

<name>maxWait</name>

<value>3000</value>

</parameter>

</ResourceParams>

<!--//

set your mailhost, and make sure you have mail.jar and activation.jar

in <tomcat>/common/lib.

//-->

<!--//

<Resource name="mail/Session" auth="Container" type="javax.mail.Session"/>

<ResourceParams name="mail/Session">

<parameter>

<name>mail.smtp.host</name>

<value>mailhost.example.com</value>

</parameter>

</ResourceParams>

//-->

</Context>

完成上面的设定后，接下来，我们修改一下Tomcat中的Connector的设定，使它能够支持UTF-8的编码，

打开 $CATALINA_HOME\conf\server.xml，做如下修改...

<!-- Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 -->

<Connector port="80"

URIEncoding="UTF-8"

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

enableLookups="false" redirectPort="8443" acceptCount="100"

debug="0" connectionTimeout="20000"

disableUploadTimeout="true" />

到这里，基本上Tomcat相关的设定就完成了，因为Roller Blog可以支持上传附件和全文检索等功能，

所以，我们还有一个设定的动作...

在 $CATALINA_HOME\WebApp\roller 中新建下面层次的目录：

$CATALINA_HOME\WebApp\roller

|

+---data

|

+---search-index

+---uploads

找到 $CATALINA_HOME\webapps\roller\WEB-INF\classes\roller.properties  ，做如下修改：

# The directory in which Roller will upload files

# uploads.dir=${user.home}/roller_data/uploads

uploads.dir=${TOMCAT_HOME}/webapps/roller/data/uploads

# force Roller to recreate the entire search index)

# search.index.dir=${user.home}/roller_data/search-index

search.index.dir=${TOMCAT_HOME}/webapps/roller/data/search-index

好了，大功告成，启动Tomcat，可以运行Roller了！
