Description
initialize.sh causes access denied error if DB server is seperated from MCF's.
Suppose each server's IP are like followings:
MySQL Server IP: A
MCF Server IP: B
and properties.xml has the follwing parameters and values:
<property name="org.apache.manifoldcf.databaseimplementationclass" value="org.apache.manifoldcf.core.database.DBInterfaceMySQL"/> <property name="org.apache.manifoldcf.dbsuperusername" value="root"/> <property name="org.apache.manifoldcf.dbsuperuserpassword" value="<password>"/> <property name="org.apache.manifoldcf.database.name" value="manifoldcf"/> <property name="org.apache.manifoldcf.mysql.server" value="A"/>
Then, executing initialize.sh causes the follwing error:
Caused by: java.sql.SQLException: Access denied for user 'manifoldcf'@'B' (using password: YES) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1073) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3609) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3541) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:943) at com.mysql.jdbc.MysqlIO.secureAuth411(MysqlIO.java:4113) at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1308) at com.mysql.jdbc.ConnectionImpl.coreConnect(ConnectionImpl.java:2336) at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2369) at com.mysql.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:2153) at com.mysql.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:792) at com.mysql.jdbc.JDBC4Connection.<init>(JDBC4Connection.java:47) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)
The problem is that MCF requests MySQL to create a new "manifoldcf" user with localhost access.
In this case, of course, MCF is on the server with IP B, MySQL should create a new user with IP Address B.
The following method is the one creating a new MySQL user in the user table.
Modifying the part where IP information is added solves this problem.
JAR NAME :mcf-core.jar
PACKAGE :org.apache.manifoldcf.core.database
CLASS NAME :DBInterfaceMySQL
METHOD NAME: public void createUserAndDatabase
if(userName != null) try { list.clear(); list.add(userName); // list.add("localhost"); list.add(IP_ADDRESS_B); list.add(password); ... ... }
I guess it would be nice if properties.xml can have a new property taking MCF server IP to
have MySQL create a "manifoldcf" user with that IP.
