Zeppelin啓用https過程和Hack內核以滿足客戶需求的記錄。
原因是這客戶很有意思，該客戶中國分公司的人爲了驗證內網安全性，從國外找了一個***測試小組對Zeppelin和其他產品進行***測試，結果發現Zeppelin主要倆問題，一個是在內網沒用https，一個是zeppelin裏面可以執行shell命令和python語句。其實這不算大問題，zeppelin本來就是幹這個用的。但是***小組不瞭解zeppelin是做什麼的，認爲即使在內網裏，執行shell命令能查看操作系統的一些文件是大問題，然後發生的事就不說了，不是我們的問題了。
不過既然他們要求整改，我們也只好配合，雖然大家都覺得內網域名加https屬於脫了褲子放屁，然後不讓zeppelin幹他本來應該乾的事就更過分了，但鑑於客戶是甲方，也只好hack源碼了。
於是某個週末用了4個小時完成所有工作。
先記錄下zeppelin加https訪問，我們有自己的域名證書，所以直接用即可。如果沒有域名證書，需要自簽發，那麼可以看第二部分，雙向認證步驟。
https第一部分，已有域名添加jks：
openssl pkcs12 -export -in xxx.com.crt -inkey xxx.com.key -out xxx.com.pkcs12 keytool -importkeystore -srckeystore xxx.com.pkcs12 -destkeystore xxx.com.jks -srcstoretype pkcs12
https第二部分，自簽發證書雙向認證添加jks
# 生成root私鑰和證書文件。 openssl genrsa -out root.key(pem) 2048 # Generate root key file openssl req -x509 -new -key root.key(pem) -out root.crt # Generate root cert file # 創建客戶端私鑰和證書以及證書請求文件csr openssl genrsa -out client.key(pem) 2048 # Generate client key file openssl req -new -key client.key(pem) -out client.csr # Generate client cert request file openssl x509 -req -in client.csr -CA root.crt -CAkey root.key(pem) -CAcreateserial -days 3650 -out client.crt # Use root cert to generate client cert file # 生成服務器端私鑰，證書和證書請求文件csr openssl genrsa -out server.key(pem) 2048 # Generate server key file, use in Zeppelin openssl req -new -key server.key(pem) out server.csr @ Generate server cert request file openssl x509 -req -in server.csr -CA root.crt -CAkey root.key(pem) -CAcreateserial -days 3650 -out server.crt # Use root cert to generate server cert file # 生成客戶端端jks文件 openssl pkcs12 -export -in client.crt -inkey client.key(pem) -out client.pkcs12 # Package to pkcs12 format, must input a password, you should remember the password keytool -importkeystore -srckeystore client.pkcs12 -destkeystore client.jks -srcstoretype pkcs12 # The client password you just input at last step # 生成服務器端jks文件 openssl pkcs12 -export -in server.crt -inkey server.key(pem) -out server.pkcs12 @ Package to pkcs12 format, must input a password, you should remember the password keytool -importkeystore -srckeystore server.pkcs12 -destkeystore server.jks -srcstoretype pkcs12 # The server password you just input at last step
如果是不需要雙向認證，只要單向自簽發，不創建客戶端的各種就可以了。
然後找個地把這些文件放過去，再修改zeppelin配置即可。
mkdir -p /etc/zeppelin/conf/ssl cp server.crt server.jks /etc/zeppelin/conf/ssl
<property> <name>zeppelin.server.ssl.port</name> <value>8443</value> <description>Server ssl port. (used when ssl property is set to true)</description> </property> <property> <name>zeppelin.ssl</name> <value>true</value> <description>Should SSL be used by the servers?</description> </property> <property> <name>zeppelin.ssl.client.auth</name> <value>false</value> <description>Should client authentication be used for SSL connections?</description> </property> <property> <name>zeppelin.ssl.keystore.path</name> <value>/etc/zeppelin/conf/ssl/xxx.com.jks</value> <description>Path to keystore relative to Zeppelin configuration directory</description> </property> <property> <name>zeppelin.ssl.keystore.type</name> <value>JKS</value> <description>The format of the given keystore (e.g. JKS or PKCS12)</description> </property> <property> <name>zeppelin.ssl.keystore.password</name> <value>password which you input on generating server jks step</value> <description>Keystore password. Can be obfuscated by the Jetty Password tool</description> </property>
然後反代那裏也加上443的ssl證書以及443轉8443的upstream即可。
然後是hack zeppelin源碼加入關鍵字限制，這個確實找了一小會zeppelin發送執行源碼給interpreter的地方，zeppelin架構比較清晰，但是代碼挺複雜的，用到了很多小花活兒。比如thrift，interpreter腳本里建立nc監聽。然後各個解釋器插件用socket跟interpreter腳本通信，前端angular，後端jetty，還用shiro做驗證和授權。回頭可以單開好幾篇說說zeppelin安裝，使用和詳細配置，做這項目基本把zeppelin摸透了。
找到發送前端編寫內容給interpreter的java代碼，然後用很生硬的辦法限制執行命令。具體那個.java文件的名字我就不說了，有懸念有驚喜。我不寫java，只負責讀源碼找到代碼位置，hack的java是同事寫的。然後編譯，替換jar包，完成。後面改了改配置，後續的***測試順利通過。

//......直到該public類結束因爲客戶有deadline限制，所以快速定位源碼位置的過程還是挺有意思的，比較緊張刺激，在這個以小時計算deadline壓力下，什麼intelliJ, Eclipse都不好使啊，就grep和vi最好用，從找到到改完，比客戶定的deadline提前了好幾個小時。
