5. 配置Cloudera Manager Agents认证Server证书

6. 配置Cloudera Manager Server认证Agent证书

环境介绍

1. CDH6.1.0

2. RedHat7.2

Certificate Authority搭建

由于CDH集群大部分都是在内网当中，无法用到PUBLIC CA，因此需要搭建内网CA，这里使用OpenSSL Certificate Authority。

2.1

Root CA

1. 创建文件夹存放keys和certificates

mkdir /root/ca

cd /root/ca
mkdir certs crl newcerts private
chmod 700 private
touch index.txt
echo 1000 > serial

3. 准备配置文件/root/ca/openssl.cnf,内容如下：

[ ca ]
# `man ca`
default_ca = CA_default
[ CA_default ]
# Directory and file locations.
dir               = /root/ca
certs             = $dir/certs
crl_dir           = $dir/crl
new_certs_dir     = $dir/newcerts
database          = $dir/index.txt
serial            = $dir/serial
RANDFILE          = $dir/private/.rand
# The root key and root certificate.
private_key       = $dir/private/ca.key.pem
certificate       = $dir/certs/ca.cert.pem
# For certificate revocation lists.
crlnumber         = $dir/crlnumber
crl               = $dir/crl/ca.crl.pem
crl_extensions    = crl_ext
default_crl_days  = 30
# SHA-1 is deprecated, so use SHA-2 instead.
default_md        = sha256
name_opt          = ca_default
cert_opt          = ca_default
default_days      = 375
preserve          = no
policy            = policy_strict
[ policy_strict ]
# The root CA should only sign intermediate certificates that match.
# See the POLICY FORMAT section of `man ca`.
countryName             = match
stateOrProvinceName     = match
organizationName        = match
organizationalUnitName  = optional
commonName              = supplied
emailAddress            = optional
[ policy_loose ]
# Allow the intermediate CA to sign a more diverse range of certificates.
# See the POLICY FORMAT section of the `ca` man page.
countryName             = optional
stateOrProvinceName     = optional
localityName            = optional
organizationName        = optional
organizationalUnitName  = optional
commonName              = supplied
emailAddress            = optional
[ req ]
# Options for the `req` tool (`man req`).
default_bits        = 2048
distinguished_name  = req_distinguished_name
string_mask         = utf8only
# SHA-1 is deprecated, so use SHA-2 instead.
default_md          = sha256
# Extension to add when the -x509 option is used.
x509_extensions     = v3_ca
[ req_distinguished_name ]
# See <https://en.wikipedia.org/wiki/Certificate_signing_request>.
countryName                     = Country Name (2 letter code)
stateOrProvinceName             = State or Province Name
localityName                    = Locality Name
0.organizationName              = Organization Name
organizationalUnitName          = Organizational Unit Name
commonName                      = Common Name

0.organizationName_default      = Alice Ltd
organizationalUnitName_default  =
emailAddress_default            =
[ v3_ca ]
# Extensions for a typical CA (`man x509v3_config`).
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid:always,issuer
basicConstraints = critical, CA:true
keyUsage = critical, digitalSignature, cRLSign, keyCertSign
[ v3_intermediate_ca ]
# Extensions for a typical intermediate CA (`man x509v3_config`).
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid:always,issuer
basicConstraints = critical, CA:true, pathlen:0
keyUsage = critical, digitalSignature, cRLSign, keyCertSign
[ usr_cert ]
# Extensions for client certificates (`man x509v3_config`).
basicConstraints = CA:FALSE
nsCertType = client, email
nsComment = "OpenSSL Generated Client Certificate"
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid,issuer
keyUsage = critical, nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = clientAuth, emailProtection
[ server_cert ]
# Extensions for server certificates (`man x509v3_config`).
basicConstraints = CA:FALSE
nsCertType = server,client
nsComment = "OpenSSL Generated Server Certificate"
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid,issuer:always
keyUsage = critical, digitalSignature, keyEncipherment
extendedKeyUsage = serverAuth,clientAuth
[ crl_ext ]
# Extension for CRLs (`man x509v3_config`).

[ ocsp ]
# Extension for OCSP signing certificates (`man ocsp`).
basicConstraints = CA:FALSE
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid,issuer
keyUsage = critical, digitalSignature
extendedKeyUsage = critical, OCSPSigning

4. 创建root key

cd /root/ca
openssl genrsa -aes256 -out private/ca.key.pem 4096
chmod 400 private/ca.key.pem

5. 创建root certificate

cd /root/ca
openssl req -config openssl.cnf \
      -key private/ca.key.pem \
      -new -x509 -days 7300 -sha256 -extensions v3_ca \
      -out certs/ca.cert.pem
chmod 444 certs/ca.cert.pem

6. 验证root certificate

openssl x509 -noout -text -in certs/ca.cert.pem

2.2

Intermediate CA

1. 在根CA目录下创建一个intermediate目录用于存放Intermediate CA的文件

mkdir /root/ca/intermediate

2. 创建Intermediate CA目录结构

cd /root/ca/intermediate
mkdir certs crl csr newcerts private
chmod 700 private
touch index.txt
echo 1000 > serial
echo 1000 > /root/ca/intermediate/crlnumber

3. 准备配置文件/root/ca/intermediate/openssl.cnf,内容如下：

[ ca ]
# `man ca`
default_ca = CA_default
[ CA_default ]
# Directory and file locations.
dir               = /root/ca/intermediate
certs             = $dir/certs

# Extension to add when the -x509 option is used.
x509_extensions     = v3_ca
[ req_distinguished_name ]
# See <https://en.wikipedia.org/wiki/Certificate_signing_request>.
countryName                     = Country Name (2 letter code)
stateOrProvinceName             = State or Province Name

[ ocsp ]
# Extension for OCSP signing certificates (`man ocsp`).
basicConstraints = CA:FALSE
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid,issuer
keyUsage = critical, digitalSignature
extendedKeyUsage = critical, OCSPSigning

4. 创建 intermediate key

cd /root/ca
openssl genrsa -aes256 \
      -out intermediate/private/intermediate.key.pem 4096
chmod 400 intermediate/private/intermediate.key.pem

5. 创建intermediate certificate signing request（CSR）

cd /root/ca
openssl req -config intermediate/openssl.cnf -new -sha256 \
      -key intermediate/private/intermediate.key.pem \
      -out intermediate/csr/intermediate.csr.pem
chmod 400 intermediate/private/intermediate.key.pem

6. 生成intermediate certificate

cd /root/ca
openssl ca -config openssl.cnf -extensions v3_intermediate_ca \
      -days 3650 -notext -md sha256 \
      -in intermediate/csr/intermediate.csr.pem \
      -out intermediate/certs/intermediate.cert.pem
chmod 444 intermediate/certs/intermediate.cert.pem

7. 像验证root certificate一样验证intermediate certificate

openssl x509 -noout -text \
      -in intermediate/certs/intermediate.cert.pem

8. 依据root certificate验证intermediate certificate，验证通过返回OK。

openssl verify -CAfile certs/ca.cert.pem \
      intermediate/certs/intermediate.cert.pem

9. 创建certificate chain file

cat intermediate/certs/intermediate.cert.pem \
      certs/ca.cert.pem > intermediate/certs/ca-chain.cert.pem
chmod 444 intermediate/certs/ca-chain.cert.pem

创建节点证书

以下操作在集群所有节点都需要操作

1. 配置JAVA_HOME环境变量

export JAVA_HOME=/usr/java/jdk1.8.0_141-cloudera
export PATH=$PATH:$JAVA_HOME/bin

2. 创建目录存放证书

mkdir -p /opt/cloudera/security/pki

3. 生成 Java keystore

$JAVA_HOME/bin/keytool -genkeypair -alias $(hostname -f) -keyalg RSA -keystore /opt/cloudera/security/pki/$(hostname -f).jks -keysize 2048 -dname "CN=$(hostname -f),OU=dev,O=macro,L=sz,ST=gd,C=zh" -ext san=dns:$(hostname -f)

4. 根据java keystore生成certificate signing request（CSR）

$JAVA_HOME/bin/keytool -certreq -alias $(hostname -f) -keystore /opt/cloudera/security/pki/$(hostname -f).jks -file /opt/cloudera/security/pki/$(hostname -f).csr -ext san=dns:$(hostname -f) -ext EKU=serverAuth,clientAuth

5. 将各节点生成的/opt/cloudera/security/pki/$(hostname -f).csr发送到自搭建的CA服务器上

scp /opt/cloudera/security/pki/$(hostname -f).csr hadoop12:/root/ca/intermediate/csr

6. 根据如下步骤在CA服务器上依次为每一个节点的CSR生成certificate

修改/root/ca/intermediate/openssl.cnf,在[ server_cert ]下添加subjectAltName=DNS:{对应的节点域名}，比如

使用如下命令为该节点生成certificate

openssl ca -config /root/ca/intermediate/openssl.cnf \
      -extensions server_cert \
      -days 3000 \
      -notext \
      -in /root/ca/intermediate/csr/hadoop12.csr \
      -out /root/ca/intermediate/certs/hadoop12.pem

依次生成其余节点的certificate

7. 将certificate发送回对应的节点的/opt/cloudera/security/pki目录下

scp /root/ca/intermediate/certs/hadoop12.pem hadoop12:/opt/cloudera/security/pki/

8. 验证每一个节点上的证书

openssl x509 -in /opt/cloudera/security/pki/$(hostname -f).pem -noout -text

在结果中需要有如下内容：

9. 拷贝root 和intermediate CA certificates到所有节点的/opt/cloudera/security/pki目录下，并重命名为rootca.pem和intca.pem

scp /root/ca/certs/ca.cert.pem hadoop12:/opt/cloudera/security/pki/rootca.pem
scp /root/ca/intermediate/certs/intermediate.cert.pem hadoop13:/opt/cloudera/security/pki/intca.pem

10. 执行如下的命令将JDK的cacerts文件拷贝到jssecacerts

cp $JAVA_HOME/jre/lib/security/cacerts $JAVA_HOME/jre/lib/security/jssecacerts

11. 将root CA certificate导入到jssecacerts当中

sudo $JAVA_HOME/bin/keytool -importcert -alias rootca -keystore $JAVA_HOME/jre/lib/security/jssecacerts -file /opt/cloudera/security/pki/rootca.pem

12. 将intermediate CA certificate添加到各节点的节点证书中，并将其导入到java keystore中

sudo cat /opt/cloudera/security/pki/intca.pem >> /opt/cloudera/security/pki/$(hostname -f).pem
sudo $JAVA_HOME/bin/keytool -importcert -alias $(hostname -f) -file /opt/cloudera/security/pki/$(hostname -f).pem -keystore /opt/cloudera/security/pki/$(hostname -f).jks

13. 创建软连接

ln -s /opt/cloudera/security/pki/$(hostname -f).pem /opt/cloudera/security/pki/agent.pem

14. 在Cloudera Manager Server节点上，创建如下软连接

ln -s /opt/cloudera/security/pki/$(hostname -f).jks /opt/cloudera/security/pki/server.jks

修改server_host为server的主机名，而不用IP

设置[Security]下的use_tls为1

分发到其他agent节点

scp /etc/cloudera-scm-agent/config.ini hadoop13:/etc/cloudera-scm-agent/

5. 重启server和所有的agent服务
