我正在尝试通过letsencrypt签署csr文件以获取签名证书并将其与Elasticsearch Shield一起使用。

创建 csr 文件：

cd CONFIG_DIR/shield
keytool -importcert -keystore node01.jks -file letsencrypt_public.pem -alias letsencrypt
keytool -genkey -alias node01 -keystore node01.jks -keyalg RSA -keysize 2048 -validity 712 -ext san=dns:domain.com,ip:11.11.11.11
keytool -certreq -alias node01 -keystore node01.jks -file node01.csr -keyalg rsa -ext san=dns:domain.com,ip:11.11.11.11

使用letsencrypt官方客户端：

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto --help
sudo ./letsencrypt-auto auth --csr /etc/elasticsearch/shield/node01.csr

输出：

 etc/elasticsearch/shield/node01.csr
 Checking for new version...
 Requesting root privileges to run letsencrypt...
 /home/usera/.local/share/letsencrypt/bin/letsencrypt --no-self-upgrade auth --csr /etc/elasticsearch/shield/node01.csr
 No handlers could be found for logger "letsencrypt.crypto_util"
 An unexpected error occurred:

 Please see the logfiles in /var/log/letsencrypt for more details.

我想当我让 Shield 工作时我会关闭 nginx，那么这里有什么问题？为什么我不能签署 csr 文件？

问题是生成的 csr 格式错误。

在 shield 中设置 ssl的完整解决方案是：

一个。安装letsencrypt并从letsencrypt获取公共cacert.pem ：

    git clone https://github.com/letsencrypt/letsencrypt
    cd letsencrypt
    ./letsencrypt-auto --help
    mkdir letsencrypt/public_pem
    mv /home/ubuntu/cacert.pem letsencrypt/public_pem

湾。创建节点密钥库并使用 Java Keytool 导入您的 CA 证书：

    cd CONFIG_DIR/shield
    sudo keytool -importcert -keystore node01.jks -file /home/ubuntu/letsencrypt/public_pem/cacert.pem -alias letsencrypt

C。使用 Java Keytool 为节点生成私钥和证书：

    sudo keytool -genkey -alias node01 -keystore node01.jks -keyalg RSA -keysize 2048 -validity 712 -ext san=dns:domain.com

    Enter keystore password:                                                  
    What is your first and last name?                                          
      [Unknown]:  domain.com                                          
    What is the name of your organizational unit?                              
      [Unknown]:  domain.com                                                   
    What is the name of your organizational?                                    
      [Unknown]:  domain                                                       
    What is the name of your City or Locality?                               
      [Unknown]:  Tel Aviv                                                     
    What is the name of your State or Province?                                
      [Unknown]:                                                               
    What is the two-letter country code for this unit?                         
      [Unknown]:  IL                                                          
    Is CN=domain.com, OU=domain.com, O=domain, L=Tel Aviv, ST=Unknown,
     C=IL correct?                                                             
      [no]:  yes

d。创建证书签名请求 (CSR)：

    sudo keytool -certreq -alias node01 -keystore node01.jks -file node01.csr -keyalg rsa -ext san=dns:domain.com
    sudo openssl req -outform der -in node01.csr -out node01.der
    sudo openssl req -inform der -in node01.der -text -noout

e. 将证书发送到您的 CA 进行签名：

    cd letsencrypt
    ./letsencrypt-auto auth --csr /etc/elasticsearch/shield/node01.der

    Checking for new version...
    Requesting root privileges to run letsencrypt...
    sudo /home/ubuntu/.local/share/letsencrypt/bin/letsencrypt --no-self-upgrade auth --csr /etc/elasticsearch/shield/node01.der

    IMPORTANT NOTES:
    - Congratulations! Your certificate and chain have been saved at
    /home/ubuntu/letsencrypt/0001_chain.pem. Your cert will expire on
    2016-05-22. To obtain a new version of the certificate in the
    future, simply run Let's Encrypt again.

F。添加到 jks 并编辑 yml：

    cd CONFIG_DIR/shield
    sudo keytool -importcert -keystore node01.jks -file /home/ubuntu/letsencrypt/0001_chain.pem -alias node01
    cd ..
    sudo nano elasticsearch.yml

    shield.ssl.keystore.path:          /etc/elasticsearch/shield/node01.jks
    shield.ssl.keystore.password:      pass
    shield.transport.ssl: true
    shield.http.ssl: true
    discovery.zen.ping_timeout: 30s

G。重新启动 Elasticsearch（不需要 nginx）。
