linux下h2集群创建，及java集成详细步骤

1.下载h2包，解压，创建server1  server2

2.进入h2/bin目录

cd h2/bin

3.建立集群

java -cp "h2-1.4.195.jar:$H2DRIVERS:$CLASSPATH" org.h2.tools.Server -tcpAllowOthers -tcpPort 9101 -webAllowOthers -webPort 8081 -baseDir /usr/local/soft/h2Cluster/server1
java -cp "h2-1.4.195.jar:$H2DRIVERS:$CLASSPATH" org.h2.tools.Server -tcpAllowOthers -tcpPort 9102 -webAllowOthers -webPort 8082 -baseDir /usr/local/soft/h2Cluster/server2
java -cp h2-1.4.195.jar org.h2.tools.CreateCluster -urlSource "jdbc:h2:tcp://127.0.0.1:9101/testCluster" -urlTarget "jdbc:h2:tcp://127.0.0.1:9102/testCluster" -user "sa" -serverList "127.0.0.1:9101,127.0.0.1:9102"

 

3.java集成

public static void main(String[] args) throws ClassNotFoundException, SQLException {
        String sourceURL = "jdbc:h2:tcp://192.168.30.130:9101,192.168.30.130:9102/testCluster";// H2DB mem
                                                                    // mode
        String user = "sa";
        String key = "";
        Class.forName("org.h2.Driver");// HSQLDB Driver
        Connection conn = DriverManager.getConnection(sourceURL, user, key);// 把驱动放入连接
        Statement stmt = conn.createStatement();
        stmt.execute("CREATE TABLE mytable(name VARCHAR(100),sex VARCHAR(10))");
        // String sql = "SELECT VALUE FROM INFORMATION_SCHEMA.SETTINGS WHERE
        // NAME='CLUSTER'";
        stmt.executeUpdate("INSERT INTO mytable VALUES('Steven Stander','male')");
        stmt.executeUpdate("INSERT INTO mytable VALUES('Elizabeth Eames','female')");
        stmt.executeUpdate("DELETE FROM mytable WHERE sex='male'");
        stmt.close();
        conn.close();
    }
