未能连接Linux 6.3中的tomcat 7网页

Question

我安装了一个已经嵌入tomcat 7的服务器。当服务器运行时，我无法访问服务器的网页。我需要的是访问管理页面.http://xxx.xxx.xx.77:8080/Nolio-app

然后我得到了下面的错误。请帮忙&谢谢！！

有关更多信息:服务器使用mysql，这需要mysql-connector java-5.1.21.jar，但我只能找到mysql-连接器-java-5.1.26-bin.jar，可以从互联网上获得。

使用以下设置的服务器。使用CATALINA_BASE: /data/Nolio-4.7

使用CATALINA_HOME: /data/Nolio-4.7

使用CATALINA_TMPDIR: /data/Nolio-4.7/temp

使用JRE_HOME：./jre

使用CLASSPATH: /data/Nolio-4.7/bin/bootstrap.jar:/data/Nolio-4.7/bin/tomcat-juli.jar

使用CATALINA_PID：./catalina.pid

Answer 1

一些最新的Nolio版本不支持直接使用Mysql，因此需要对其进行一些配置。这是Nolio知识库，关于如何配置4.7版本来使用Mysql - Nolio4.7-没有数据库配置的自定义安装这应该可以解决您的问题。

Answer 2

在尝试使用JDBC使用PersistentManager配置MySQL时，我也遇到了同样的异常。我只需将mysql-连接器jar (例如mysql-连接器-java-5.1.34-bin.jar)复制到我的tomcat库目录(tomcatDir/lib/)。

如果连接字符串不正确，则会得到另一个错误：

org.apache.catalina.session.JDBCStore getConnection
SEVERE: A SQL exception occurred com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'invalidDB'
