背景
由于漏洞现有版本需要升级到5.6.12，试着自己搭建并且将现有5.2.2版本的数据迁移到5.6.12
下载地址：https://www.elastic.co/cn/downloads/past-releases/elasticsearch-5-6-12
ik分词器下载地址：https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v5.6.16
cerebrox下载地址：https://github.com/lmenezes/cerebro/tags
安装
注意这里用非root安装，并且依赖jdk1.8(自己安装)
准备3台虚拟机：
ip1:192.168.0.4
ip2:192.168.0.5
ip3:192.168.0.6
tar -zxvf elasticsearch-5.6.16.tar.gz
进入elasticsearch-5.6.16文件夹的config目录，打开elasticsearch.yml编辑
cluster.name: es5.6
node.name: es5.6-d1
#开启Master节点
node.master: true
#开启数据节点
node.data: true
bootstrap.seccomp: false
bootstrap.memory_lock: false
network.host: 192.168.0.4
http.port: 9003
transport.tcp.port: 9103
discovery.zen.ping.unicast.hosts: ["192.168.0.4:9103","192.168.0.5:9103","192.168.0.6:9103"]
discovery.zen.minimum_master_nodes: 2
#数据路径
path.data: /home/elastic/elasticsearch-5.6.16/data
path.logs: /home/elastic/elasticsearch-5.6.16/logs
编辑config/jvm.options
-Xms4g
-Xmx4g
进入elasticsearch-5.6.16/plugins 新建文件夹ik，把下载的ik分词器的文件考入
其他2台同上配置，需要把network.host改成相对应的Ip，node.name也改成es5.6-d2, es5.6-d3
启动
启动命令
sh ./elasticsearch-5.6.16/bin/elasticsearch -d
cerebrox安装
直接解压，进入当前cerebrox/conf,
编辑application.conf文件
hosts = [
#{
# host = "http://localhost:9200"
# name = "Localhost cluster"
# headers-whitelist = [ "x-proxy-user", "x-proxy-roles", "X-Forwarded-For" ]
#}
# Example of host with authentication
{
host = "http://192.168.0.4:9003"
name = "es5.6"
auth = {
username = "test"
password = "test"
}
},
{
host = "http://192.168.0.5:9003"
name = "es5.6"
auth = {
username = "test"
password = "test"
}
},
{
host = "http://192.168.0.6:9003"
name = "es5.6"
auth = {
username = "test"
password = "test"
}
}
]
运行：windows运行：bin/cerebro.bat ， linux运行：bin/cerebro，

数据迁移
将原来5.2.2的数据直接拷贝到5.6.12的data里面，然后启动5.6.12
