otter学习（1）—otter_manager 安装配置（快速开始）

一、环境准备

Zookeeper：192.168.134.128:2181
Mysql：192.168.134.129:3306
manager：192.168.134.133:8080

1、otter manager依赖于mysql进行配置信息的存储，所以需要预先安装mysql，并初始化otter manager的系统表结构

a. 安装mysql：[MySQL系列—服务器安装与配置](http://blog.csdn.net/u012758088/article/details/74906719)

b. 初始化otter manager系统表：

[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget https://raw.github.com/alibaba/otter/master/manager/deployer/src/main/resources/sql/otter-manager-schema.sql

[root@localhost src]# service mysqld start
Starting MySQL..... SUCCESS! 

[root@localhost src]# /usr/local/mysql/bin/mysql -uroot -p888888

mysql> source /usr/local/src/otter-manager-schema.sql

2、整个otter架构依赖了zookeeper进行多节点调度，所以需要预先安装zookeeper，不需要初始化节点，otter程序启动后会自检

a. manager需要在otter.properties中指定一个就近的zookeeper集群机器

二、下载并解压 otter manager

直接下载，可访问：https://github.com/alibaba/otter/releases ，会列出所有历史的发布版本包下载方式。

[root@localhost /]# cd /usr/local/src/
[root@localhost src]# wget https://github.com/alibaba/otter/releases/download/v4.2.14/manager.deployer-4.2.14.tar.gz
[root@localhost src]# mkdir /usr/local/manager
[root@localhost src]# tar zxvf manager.deployer-4.2.13.tar.gz -C /usr/local/manager/

三、配置修改

[root@localhost manager]# vim conf/otter.properties 

## otter manager domain name，修改为正确访问ip，生成URL使用
otter.domainName = 192.168.134.133
## otter manager http port
otter.port = 8080
## jetty web config xml
otter.jetty = jetty.xml

## otter manager database config，修改为正确数据库信息
otter.database.driver.class.name = com.mysql.jdbc.Driver
otter.database.driver.url = jdbc:mysql://192.168.134.129:3306/otter
otter.database.driver.username = root
otter.database.driver.password = 888888

## otter communication port
otter.communication.manager.port = 1099

## otter communication pool size
otter.communication.pool.size = 10

## default zookeeper address，修改为正确的地址，手动选择一个地域就近的zookeeper集群列表
otter.zookeeper.cluster.default = 192.168.134.128:2181
## default zookeeper sesstion timeout = 60s
otter.zookeeper.sessionTimeout = 60000

## otter arbitrate connect manager config
otter.manager.address = ${otter.domainName}:${otter.communication.manager.port}

## should run in product mode , true/false
otter.manager.productionMode = true

## self-monitor enable or disable
otter.manager.monitor.self.enable = true
## self-montir interval , default 120s
otter.manager.monitor.self.interval = 120
## auto-recovery paused enable or disable
otter.manager.monitor.recovery.paused = true
# manager email user config
otter.manager.monitor.email.host = smtp.gmail.com
otter.manager.monitor.email.username =
otter.manager.monitor.email.password =
otter.manager.monitor.email.stmp.port = 465

四、准备启动

[root@localhost manager]# ./bin/startup.sh

五、查看日志

[root@localhost manager]# vim logs/manager.log 

2017-12-14 13:01:55.360 [] INFO  com.alibaba.otter.manager.deployer.OtterManagerLauncher - ## start the manager server.
2017-12-14 13:04:20.766 [] INFO  com.alibaba.otter.manager.deployer.JettyEmbedServer - ##Jetty Embed Server is startup!
2017-12-14 13:04:20.929 [] INFO  com.alibaba.otter.manager.deployer.OtterManagerLauncher - ## the manager server is running now ......

出现类似日志，代表启动成功。

注意：一定要多等一会，从打印的日志可以看出，启动过程持续的3-4分钟。

六、验证

访问： http://192.168.134.133:8080，出现otter的页面，即代表启动成功。
otter学习（1）—otter_manager 安装配置（快速开始）
访问：http://192.168.134.133:8080/login.htm，初始密码为：admin/admin，即可完成登录. 目前：匿名用户只有只读查看的权限，登录为管理员才可以有操作权限。

附：配置过程中的问题

启动的过程中出现以下错误

网上有好多解决方法，试了试都没用。仔细看看错误日志，错误好像和JDK的版本有关，换成了 JDK 6 之后，启动成功。
