一、安装es
1、解压重命名安装包
tar -zxvf elasticsearch-6.4.3.tar.gz -C /usr/local/ mv elasticsearch-6.4.3/ elasticsearch
2、创建es组和es用户
[root@cluster1_host1 elasticsearch]# groupadd es [root@cluster1_host1 elasticsearch]# useradd es -g es [root@cluster1_host1 elasticsearch]# passwd es
3、修改es目录的属组
chown -R es:es /usr/local/elasticsearch/
4、分发配置到其他节点
scp -r /usr/local/elasticsearch/ root@10.87.18.33:/usr/local/
5、修改 /etc/security/limits.conf
* soft nofile 65536 * hard nofile 65536 * soft nproc 65536 * hard nproc 65536
6、修改/etc/sysctl.conf
vm.max_map_count=262144
7、启动es
[root@cluster1_host1 ~]# curl '10.87.18.31:9200/_cat/nodes?v' ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 10.87.18.32 27 12 6 0.59 0.25 0.10 mdi * cluster1_host2 10.87.18.33 24 13 7 0.31 0.16 0.07 mdi - cluster1_host1 10.87.18.31 28 13 6 0.41 0.24 0.11 mdi - cluster1_host1
二、配置er的search-guard插件
1、下载 search-guard插件
https://repo1.maven.org/maven2/com/floragunn/search-guard-6/6.4.3-25.5/search-guard-6-6.4.3-25.5.zip
2、下载tsltools插件，生成证书
https://repo1.maven.org/maven2/com/floragunn/search-guard-tlstool/1.7/search-guard-tlstool-1.7.tar.gz
3、每个节点执行如下命令，标红的设置为每个节点的hostname
curl -Ss -XPUT 'http://cluster1_host3:9200/_cluster/settings?pretty' \
-H 'Content-Type: application/json' -d'
{
"persistent": {
"cluster.routing.allocation.enable": "none"
}
}
'
然后关闭es
4、安装search-guard插件，每个节点都需要安装
[es@cluster1_host1 bin]$ ./elasticsearch-plugin install -b file:///es/search-guard-6-6.4.3-25.5.zip -> Downloading file:///es/search-guard-6-6.4.3-25.5.zip
5、tsltools生成证书，解压安装包
tar -zxvf search-guard-tlstool-1.7.tar.gz -C /usr/local/search-guard-tlstool/
6、复制模板的配置文件
[es@cluster1_host1 config]$ cp example.yml tlsconfig.yml [es@cluster1_host1 config]$ ll total 24 -rw-r--r--. 1 es es 4731 Jun 5 2019 example.yml -rw-r--r--. 1 es es 5634 Jun 5 2019 template.yml -rw-r--r--. 1 es es 4731 Feb 29 02:43 tlsconfig.yml [es@cluster1_host1 config]$ pwd /usr/local/search-guard-tlstool/config [es@cluster1_host1 config]$
7、修改配置文件
[es@cluster1_host1 config]$ cat tlsconfig.yml

8、将安装目录拷贝到节点，并修改属组为es
[root@cluster1_host1 data]# scp -r /usr/local/search-guard-tlstool/ root@10.87.18.33:/usr/local/
9、生成证书文件
创建证书文件生成目录
[es@cluster1_host1 config]$ cd /usr/local/elasticsearch/config [es@cluster1_host1 config]$ mkdir out
10、生成证书的命令
[es@cluster1_host1 tools]$ ./sgtlstool.sh -c /usr/local/search-guard-tlstool/config/tlsconfig.yml -ca -crt -t /usr/local/elasticsearch/config/out/ Root certificate and signing certificate have been sucessfully created. Created 6 node certificates. Created 2 client certificates.
11、生成的证书文件如下
[es@cluster1_host1 out]$ cd /usr/local/elasticsearch/config/out/ [es@cluster1_host1 out]$ ll total 96 -rw-rw-r--. 1 es es 294 Feb 29 02:59 client-certificates.readme -rw-rw-r--. 1 es es 1388 Feb 29 02:59 cluster1_host1_elasticsearch_config_snippet.yml -rw-rw-r--. 1 es es 1801 Feb 29 02:59 cluster1_host1_http.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host1_http.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 cluster1_host1.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host1.pem -rw-rw-r--. 1 es es 1388 Feb 29 02:59 cluster1_host2_elasticsearch_config_snippet.yml -rw-rw-r--. 1 es es 1789 Feb 29 02:59 cluster1_host2_http.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host2_http.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 cluster1_host2.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host2.pem -rw-rw-r--. 1 es es 1388 Feb 29 02:59 cluster1_host3_elasticsearch_config_snippet.yml -rw-rw-r--. 1 es es 1801 Feb 29 02:59 cluster1_host3_http.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host3_http.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 cluster1_host3.key -rw-rw-r--. 1 es es 3201 Feb 29 02:59 cluster1_host3.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 kirk.key -rw-rw-r--. 1 es es 3144 Feb 29 02:59 kirk.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 root-ca.key -rw-rw-r--. 1 es es 1371 Feb 29 02:59 root-ca.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 signing-ca.key -rw-rw-r--. 1 es es 1558 Feb 29 02:59 signing-ca.pem -rw-rw-r--. 1 es es 1801 Feb 29 02:59 spock.key -rw-rw-r--. 1 es es 3144 Feb 29 02:59 spock.pem
12、验证证书
[es@cluster1_host1 out]$ /usr/local/search-guard-tlstool/tools/sgtlsdiag.sh -ca /usr/local/elasticsearch/config/out/root-ca.pem -crt /usr/local/elasticsearch/config/out/cluster1_host1.pem

{"message":null,"mode":"strict","status":"UP"}
18、携带用户名和密码访问es
[root@cluster1_host1 ~]# curl -u admin:admin '10.87.18.31:9200/_cat/indices?v' health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open searchguard XOWOuXN0SJi_69Yz3BPtmw 1 2 0 6 88.6kb 38.4kb [root@cluster1_host1 ~]#
es的search-guard插件配置完成
三、问题
1、如果启动es报错
[2020-02-29T03:54:12,266][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [cluster1_host1] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Cannot have additional setting [http.type] in plugin [search-guard-6], already added in plugin [x-pack-security]
则需要修改es的配置文件
xpack.security.enabled: false
2、如果启动es有告警
[2020-02-29T03:49:24,286][WARN ][c.f.s.SearchGuardPlugin ] Directory /usr/local/elasticsearch/config has insecure file permissions (should be 0700) [2020-02-29T03:49:24,286][WARN ][c.f.s.SearchGuardPlugin ] Directory /usr/local/elasticsearch/config/out has insecure file permissions (should be 0700) [2020-02-29T03:49:24,286][WARN ][c.f.s.SearchGuardPlugin ] File /usr/local/elasticsearch/config/out/root-ca.pem has insecure file permissions (should be 0600) [2020-02-29T03:49:24,286][WARN ][c.f.s.SearchGuardPlugin ] File /usr/local/elasticsearch/config/out/root-ca.key has insecure file permissions (should be 0600) [2020-02-29T03:49:24,286][WARN ][c.f.s.SearchGuardPlugin ] File /usr/local/elasticsearch/config/out/signing-ca.pem has insecure file permissions (should be 0600)
则修改权限
chmod 0600 /usr/local/elasticsearch/config/out/* chmod 0700 /usr/local/elasticsearch/config/
3、如果执行es命令有如下报错
[root@cluster1_host1 config]# curl '10.87.18.31:9200/_cat/nodes?v' Search Guard not initialized (SG11). See http://docs.search-guard.com/v6/sgadmin[root@cluster1_host1 config]
进入如下目录
[es@cluster1_host1 search-guard-6]$ pwd /usr/local/elasticsearch/plugins/search-guard-6
做如下修改，如果报文件不存在，则重启es在试一次，只需要在一个节点执行即可
[es@cluster1_host1 search-guard-6]$ ./tools/sgadmin.sh -cd ./sgconfig/ -icl -nhnv -cert ../../config/out/kirk.pem -key ../../config/out/kirk.key -cacert ../../config/out/root-ca.pem -h cluster1_host1 -keypass teststt Search Guard Admin v6 Will connect to cluster1_host1:9300 ... done Elasticsearch Version: 6.4.3 Search Guard Version: 6.4.3-25.5 Connected as CN=kirk.example.com,OU=Ops,O=Example Com\, Inc.,DC=example,DC=com Contacting elasticsearch cluster 'elasticsearch' and wait for YELLOW clusterstate ...
