编译
mvn clean install -Dmaven.test.skip eclipse:eclipse

pom.xml 里增加
org.apache.maven.plugins
maven-compiler-plugin
2.0.2
1.8
编译成功后生成war包
kafka-eagle-web/target/ke.war
部署到 tomcat下 Apache Tomcat/8.5.32 ,注意需要部署到 /webapps/ke/
/webapps/ke/ke.war
因为 jsp 里把应用路径写死了
解压war包
jar xvf ke.war
配置文件
classes/system-config.properties
WEB-INF/classes/spring-mybatis.xml
# kafka.eagle.zk.cluster.alias=cluster1,cluster2
kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=10.57.31.22:2182
#cluster2.zk.list=xdn1:2181,xdn2:2181,xdn3:2181
cluster1.kafka.eagle.offset.storage=kafka
# Zkcli limit -- Zookeeper cluster allows the number of clients to connect to
kafka.zk.limit.size=25
# Kafka Eagle webui port -- WebConsole port access address
kafka.eagle.webui.port=9050
# Default use sqlite to store data
kafka.eagle.driver=org.sqlite.JDBC
# It is important to note that the path must exist.
kafka.eagle.url=jdbc:sqlite:/Users/dugang/soft/tomcat/ke9050/ke.db
kafka.eagle.username=
kafka.eagle.password=
其他配置先忽略 , 不开启 钉钉和微信报警
kafka.eagle.im.dingding.enable=false
kafka.eagle.im.wechat.enable=false
cluster1.kafka.eagle.sasl.enable=false
在 mac 下,启动成功
部署到linux上之后 启动报错
2019-04-25 16:51:39 INFO [PostProcessorRegistrationDelegate$BeanPostProcessorChecker.localhost-startStop-1] - Bean 'keAuthc' of type [class org.smartloli.kafka.eagle.web.sso.filter.SSOFilter] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

跟踪 代码 KafkaZKPoolUtils > SystemConfigUtils
不同的操作系统,配置文件加载路径不一样
String osName = System.getProperties().getProperty("os.name");
if (osName.contains("Mac") || osName.contains("Win")) {
mConfig.load(SystemConfigUtils.class.getClassLoader().getResourceAsStream(name));
} else {
mConfig.load(new FileInputStream(System.getProperty("user.dir") + "/conf/" + name));
}
修改 此处代码 ,直接从类路径加载
mConfig.load(SystemConfigUtils.class.getClassLoader().getResourceAsStream(name));
重新打包部署后,Linux上也可以正常启动
数据库初始化
org.smartloli.kafka.eagle.web.controller.StartupListener
String jdbc = SystemConfigUtils.getProperty("kafka.eagle.driver");
if (JConstants.MYSQL_DRIVER.equals(jdbc)) {
MySqlRecordSchema.schema();
} else if (JConstants.SQLITE_DRIVER.equals(jdbc)) {
SqliteRecordSchema.schema();
}
支持 mysql 和 sqlite
建库脚本定义
org.smartloli.kafka.eagle.plugin.util.JConstants
用户名和密码
static String CREATE_TABLE_SQLITE_KE_USERS = "CREATE TABLE IF NOT EXISTS `ke_users` (`id` integer primary key autoincrement,`rtxno` int(11) NOT NULL,`username` varchar(64) NOT NULL,`password` varchar(128) NOT NULL,`email` varchar(64) NOT NULL,`realname` varchar(128) NOT NULL)";
static String CREATE_TABLE_SQLITE_KE_USERS_INSERT = "INSERT INTO `ke_users` VALUES ('1', '1000', 'admin', '123456', 'admin@email.com', 'Administrator')";
admin/123456
