otter双主同步安装与配置

      otter是阿里的开源数据同步项目，资源地址就不用说了哈，网上找，阿里云论坛关于单方向同步的配置已经很清楚了，理论上说，双主同步也不复杂，但是毕竟

是数据库，比较重要，配置双主的时候，总觉得心里没底，所以记录下来。本文主要来源于https://yq.aliyun.com/articles/58388?spm=5176.100239.blogcont58420.18.Hof0oq

1，  java环境，yum即可

2，  zookeeper配置

修改bin/zkEnv.sh脚本：

将ZOO_LOG_DIR="."修改为ZOO_LOG_DIR="/tmp/zookeeper/data"

将ZOO_LOG4J_PROP=”INFO,CONSOLE”修改为ZOO_LOG4J_PROP="INFO,ROLLINGFILE"

3,安装配置manager

tar zxvf manager.deployer-$version.tar.gz -C /tmp/manager

导入数据库

source /tmp/manager/otter-manager-schema.sql

修改vim conf/otter.properties 配置文件

## otter manager domain name #修改为正确访问ip(内网访问配置内网地址外网访问配置外网地址)，生成URL使用
otter.domainName = 127.0.0.1    
## otter manager http port
otter.port = 8080

## otter manager database config ，修改为正确数据库信息
otter.database.driver.url = jdbc:mysql://127.0.01:3306/ottermanager
otter.database.driver.username = root
otter.database.driver.password = hello

## 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,zookeeper默认端口 2181
otter.zookeeper.cluster.default = 127.0.0.1:2181

启动manager

./bin/startup.sh


NODE搭建

1，我们在介绍otter的特性里面有提及到aria2,它是一个文件通道来保证需要同步的数据通过极快的速度同步到需要同步的服务器上

cd /app/install/
tar zxvf aria2-1.17.1.tar.gz
mv aria2-1.17.1 aria2
cd aria2
./configure
make
make install
# 验证安装是否成功
aria2c -v
# 会输出
aria2 version 1.17.1    

安装配置node

接下来我们来配置node,node主要负责接受manage下发任务的处理

mkdir /tmp/node
tar zxvf /app/install/node.deployer-4.2.13.tar.gz  -C /tmp/node
cd /tmp/node/
# nid配置node的ID多个node协同工作时不能重复
echo 1 > conf/nid
# 修改配置文件
vim conf/otter.properties
# 主要是确认连接manager地址是否正确(这里使用服务器内网地址进行配置)
otter.manager.address = 10.144.159.182:1099

配置完成之后我们不要着急启动node,因为启动了node要是manager没有配置是没法建立连接的,顺序是先配置好manager在开启node.

在web 界面中关联manager,zookeeper和node
登录


配置zookeeper

配置好node的一些参数

• 机器名称：可以随意定义，方便自己记忆即可
• 机器ip：对应node节点将要部署的机器ip，如果有多ip时，可选择其中一个ip进行暴露. (此ip是整个集群通讯的入口，实际情况千万别使用127.0.0.1，否则多个机器的node节点会无法识别)
• 机器端口：对应node节点将要部署时启动的数据通讯端口，建议值：2088
• 下载端口：对应node节点将要部署时启动的数据下载端口，建议值：9090
• 外部ip ：对应node节点将要部署的机器ip，存在的一个外部ip，允许通讯的时候走公网处理。
• zookeeper集群：为提升通讯效率，不同机房的机器可选择就近的zookeeper集群

node这种设计，是为解决单机部署多实例而设计的，允许单机多node指定不同的端口:

在数据库中执行下面这个sql脚本，双主上都要执行
