这里使用的是 elasticsearch-2.3.5

大神的Github地址:https://github.com/floragunncom

功能:可以按组,按用户,按index,按type,按field,进行精细的权限控制。非常强大!媲美Shield

安装ES插件

bin/plugin install -b com.floragunn/search-guard-ssl/2.3.5.15
bin/plugin install -b com.floragunn/search-guard-2/2.3.5.5

安装成功后,目录如下:

/usr/local/elk/elasticsearch-2.3.5

.
├── bin
├── config
│   └── scripts
├── data
│   └── elasticsearch
├── lib
├── logs

│   └── reindex
└── plugins
    ├── head
    ├── ik
    ├── kopf
    ├── search-guard-2
    └── search-guard-ssl

下载 searchguard-ssl 的包,里面包含自动创建证书的脚本:

wget https://github.com/floragunncom/search-guard-ssl/archive/v2.3.5.15.zip
unzip v2.3.5.15.zip
cd search-guard-ssl-2.3.5.15/example-pki-scripts/

有三个脚本

gen_client_node_cert.sh 创建客户端证书
gen_node_cert.sh        创建节点证书
gen_root_ca.sh          创建根证书

修改脚本:

vim gen_client_node_cert.sh
找到这行:-dname "CN=$CLIENT_NAME, OU=client, O=client, L=Test, C=DE"
修改为:-dname "CN=$CLIENT_NAME"

vim gen_node_cert.sh
找到这行:-dname "CN=$NODE_NAME.example.com, OU=SSL, O=Test, L=Test, C=DE" \
修改为:-dname "CN=$NODE_NAME" \

编辑脚本 vim example.sh

#!/bin/bash
set -e
./clean.sh
./gen_root_ca.sh password password 
./gen_node_cert.sh node-0 password  password 
./gen_node_cert.sh node-1 password  password 
./gen_client_node_cert.sh admin password password 
cp truststore.jks node-0-keystore.jks /usr/local/elk/elasticsearch-2.3.5/config/
cp truststore.jks admin-keystore.jks /usr/local/elk/elasticsearch-2.3.5/plugins/search-guard-2/sgconfig/

此时在当前目录下,会生成这么几个文件

node-0-keystore.jks
node-1-keystore.jks
admin-keystore.jks
truststore.jks

上面只列出了node-0节点,需要拷贝哪些文件,node-1节点,需要和上面类似处理。

接下来配置 ESconfig/elasticsearch.yml

启动 ES 集群

./plugins/search-guard-2/tools/sgadmin.sh -cn 集群名称 -h hostname -cd plugins/search-guard-2/sgconfig -ks plugins/search-guard-2/sgconfig/admin-keystore.jks -kspass password -ts plugins/search-guard-2/sgconfig/truststore.jks -tspass password -nhnv

hostname:指的是 network.host 设置的值

执行脚本的结果如下:

Will connect to YourIP:9300 ... done
Contacting elasticsearch cluster 'YourCluster' and wait for YELLOW clusterstate ...
Clustername: YourCluster
Clusterstate: GREEN
Number of nodes: 4
Number of data nodes: 4
Search Guard index already exists, so we do not need to create one.
Populate config from /usr/local/elk/elasticsearch-2.3.5/plugins/search-guard-2/sgconfig
Will update 'config' with plugins/search-guard-2/sgconfig/sg_config.yml
   SUCC: Configuration for 'config' created or updated
Will update 'roles' with plugins/search-guard-2/sgconfig/sg_roles.yml
   SUCC: Configuration for 'roles' created or updated
Will update 'rolesmapping' with plugins/search-guard-2/sgconfig/sg_roles_mapping.yml
   SUCC: Configuration for 'rolesmapping' created or updated
Will update 'internalusers' with plugins/search-guard-2/sgconfig/sg_internal_users.yml
   SUCC: Configuration for 'internalusers' created or updated
Will update 'actiongroups' with plugins/search-guard-2/sgconfig/sg_action_groups.yml
   SUCC: Configuration for 'actiongroups' created or updated
Done with success

然后访问 ES 时,就输入用户名和密码就可以了。
