ElasticSearch日常使用脚本
1.启动服务要切换到非root账户 （例子：su - elk --command="/usr/local/elk/kibana/bin/kibana serve &"）
2.常用操作命令
vim 进入文件
cd 进入指定目录
w 智能提示
q! 不保存
wq 保存
esc 停止编辑
: 输入命令
i 进入编辑
& 加在最后可以使后台运行
ps -ef | grep elastic 查找ES进程
kill -9 2382（进程号） 杀掉ES进程
sh elasticsearch -d 重启ES
安装Wget：
yum install wget (基于 YUM 的系统)
apt--get install wget (基于 APT 的系统)
du -sh ./* 查看目录属性（大小等）
yum -y install java 安装java
wget url 下载并安装指定的url包
tar -zcvf v5.5.0.tar.gz /usr/local/elasticsearch/plugins/ik 解压
chown -R elk.elk /路径 授权 （例子：chown -R elk.elk /usr/local/elk/elasticsearch/logs/elasticsearch.log）
ifconfig 查看ip
poweroff 关闭虚拟机
su - elastic --command="/usr/local/elk/elasticsearch/bin/elasticsearch -d" 启动es （/usr/local/kibana/bin/kibana &）
虚拟机乔连模式可以生成内网IP
ES:
来获取所有接口：curl '192.168.1.135:9200/_cat?help’
检查集群健康：curl '192.168.1.135:9200/_cat/health?v'
集群中的节点列表：curl '192.168.1.135:9200/_cat/nodes?v'
列出所有的索引：curl '192.168.78.129:9200/_cat/indices?v'
搜索：curl '192.168.78.128:9200/${index}/${type}/_search'
查集群状态：curl '192.168.1.135:9200/_cat/nodes?v’
查看分片状态：curl '192.168.1.135:9200/_cat/shards?v’
查看映射 curl -XGET "http://192.168.1.135:9200/yqtrackv5_cache06/_mapping?pretty"
删除索引 curl -XDELETE 'http://192.168.1.135:9200/shakespeare'
----修改ip
vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改前：
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=172.16.1.186
GATEWAY=172.16.1.1
修改后：
DEVICE=eth0
TYPE=Ethernet
HWADDR=00:0C:29:E6:8E:B6
UUID=7fc9a981-f305-45fc-803c-fdaf471aa9d0
NM_CONTROLLED=yes
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.1.135
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
----搜索区别
Filter 会根据情况缓存bitset，只根据提交筛选，没有其他排序功能
query 不会缓存，可以根据条件搜索，可排序

一、数据备份
1、备份源数据库配置文件添加存储仓库(可设置多个)并重启(如果启动已经配置了则不需重启)
path.repo: ["/log/backup"]
2、添加快照位置到存储仓库
curl -XPUT http://127.0.0.1:9200/_snapshot/backup -d '{"type": "fs","settings": {"location": "/log/backup"}}'
3、执行备份可针对指定索引
curl -XPUT http://127.0.0.1:9200/_snapshot/backup/snapshot_1?wait_for_completion=true -d '{"indices": ".kibana"}'
二、数据恢复
1、恢复目标数据库配置文件添加存储仓库(可设置多个)并重启(如果启动已经配置了则不需重启)
path.repo: ["/data/backup"]
2、添加快照位置到存储仓库
curl -XPUT http://127.0.0.1:9200/_snapshot/backup -d '{"type": "fs","settings": {"location": "/data/backup"}}'
3、恢复
curl -XPOST http://127.0.0.1:9200/_snapshot/backup/snapshot_1/_restore?wait_for_completion=true -d '{"indices": ".kibana"}'
三、删除备份
curl -XDELETE http://127.0.0.1:9200/_snapshot/backup/snapshot_1
注意事项:
1、特别注意恢复和备份的位置对应的Elasticsearch进程是否有读写权限
node.master: true
node.data: true
node.ingest: false

Shard Rebalancing Settingsedit
The following dynamic settings may be used to control the rebalancing of shards across the cluster:
cluster.routing.rebalance.enable
Enable or disable rebalancing for specific kinds of shards:
all- (default) Allows shard balancing for all kinds of shards.primaries- Allows shard balancing only for primary shards.replicas- Allows shard balancing only for replica shards.none- No shard balancing of any kind are allowed for any indices.
cluster.routing.allocation.allow_rebalance
Specify when shard rebalancing is allowed:
always- Always allow rebalancing.indices_primaries_active- Only when all primaries in the cluster are allocated.indices_all_active- (default) Only when all shards (primaries and replicas) in the cluster are allocated.
cluster.routing.allocation.cluster_concurrent_rebalance
Allow to control how many concurrent shard rebalances are allowed cluster wide. Defaults to 2. Note that this setting only controls the number of concurrent shard relocations due to imbalances in the cluster. This setting does not limit shard relocations due to allocation filtering or forced awareness.
