安装

下载

Download

git clone

$ git clone https://github.com/ltsopensource/light-task-scheduler

打包

文件在 light-task-scheduler

$ cd ~/it/tools/light-task-scheduler/
$ ls
LICENSE			build.sh		lts-admin		lts-jobtracker		lts-startup		开发计划.md
README.md		docs			lts-core		lts-monitor		lts-tasktracker		开发者规范.md
build.cmd		lts			lts-jobclient		lts-spring		pom.xml

只打包 lts-admin。

你需要执行 clean install lts-core 和 clean install lts-monitor，然后再打包 lts-admin。

日志可能如下所示：

注意:

确保已经创建了数据库 lts
MySQL 访问应该是 root/root，

或者你需要将 lts-admin.cfg 和 lts-monitor.cfg 中的数据库访问改成 lts-admin 的样式，如下所示：

# ------ 这个是Admin存储数据的地方,也可以和JobQueue的地址一样 ------
configs.jdbc.url=jdbc:mysql://127.0.0.1:3306/lts
configs.jdbc.username=root
configs.jdbc.password=123456

tomcat 启动

Tomcat run

拷贝 lts-admin-${version}.war 到 tomcat

$ mv /Users/houbinbin/IT/tools/light-task-scheduler/lts-admin/target/lts-admin-1.7.0-SNAPSHOT.war ~/it/tools/tomcat/tomcat8/webapps/ROOT.war
$ cd ~/it/tools/tomcat/tomcat8/webapps

$ ls
ROOT		ROOT.war

或者在 lts-admin module 使用 tomcat 插件。

$   mvn tomcat7:run

访问

在浏览器中输入 localhost:8081，默认访问的用户名和密码是 admin/admin。

Quick Start

准备

通过 idea 打开入门例子， Import example

1） Start Zookeeper

2） Start MySQL

3）创建 lts 数据库。

mysql> use lts;
Database changed
mysql> show tables;
Empty set (0.00 sec)

运行

Start JobTracker

如果你的 MySQL 登录不是 root/root，你需要在 lts.properties 中更改 MySQL 配置，然后运行：

在 LTS-Admin 的管理页面上，您可以获取有关它们的信息。

Try in Ubuntu

下载

$   git clone https://github.com/ztajy/light-task-scheduler.git

root@iZuf60ahcky4k4nfv470juZ:~/code/light-task-scheduler# ls
build.cmd  build.sh  docs  lts  lts-admin  lts-core  lts-example  lts-jobclient  lts-jobtracker  lts-logger  lts-queue  lts-spring  lts-startup  lts-tasktracker  pom.xml  README.md

部署

JobTracker和LTS-Admin部署

1、运行根目录下的sh build.sh或build.cmd脚本，会在dist目录下生成lts-{version}-bin文件夹

$   sh  build.sh

...
...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 5.245 s
[INFO] Finished at: 2016-09-27T14:06:20+08:00

root@iZuf60ahcky4k4nfv470juZ:~/code/light-task-scheduler/dist# pwd
/root/code/light-task-scheduler/dist
root@iZuf60ahcky4k4nfv470juZ:~/code/light-task-scheduler/dist# ls
lts-1.6.3-SNAPSHOT-bin

2、下面是其目录结构，其中bin目录主要是JobTracker和LTS-Admin的启动脚本。 jobtracker 中是 JobTracker的配置文件和需要使用到的jar包，lts-admin是LTS-Admin相关的war包和配置文件。

lts-{version}-bin的文件结构

├── bin
│   ├── jobtracker.cmd
│   ├── jobtracker.sh
│   ├── lts-admin.cmd
│   └── lts-admin.sh
├── jobtracker
│   ├── conf
│   │   └── zoo
│   │       ├── jobtracker.cfg
│   │       └── log4j.properties
│   └── lib
│       └── *.jar
├── lts-admin
│   ├── conf
│   │   ├── log4j.properties
│   │   └── lts-admin.cfg
│   ├── lib
│   │   └── *.jar
│   └── lts-admin.war
└── tasktracker
    ├── bin
    │   └── tasktracker.sh
    ├── conf
    │   ├── log4j.properties
    │   └── tasktracker.cfg
    └── lib
        └── *.jar

3、JobTracker启动。如果你想启动一个节点，直接修改下conf/zoo下的配置文件，然后运行 sh jobtracker.sh zoo start即可，如果你想启动两个JobTracker节点，那么你需要拷贝一份zoo,譬如命名为zoo2,修改下zoo2下的配置文件，然后运行sh jobtracker.sh zoo2 start即可。logs文件夹下生成jobtracker-zoo.out日志。

4、LTS-Admin启动.修改lts-admin/conf下的配置，然后运行bin下的sh lts-admin.sh或lts-admin.cmd脚本即可。 logs文件夹下会生成lts-admin.out日志，启动成功在日志中会打印出访问地址，用户可以通过这个访问地址访问了。
