1、搭建ambari 時遇見的問題 [root@hadoop-master ~]# yum -y install ambari-server Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package ambari-server.x86_64 0:2.7.3.0-139 will be installed --> Processing Dependency: postgresql-server >= 8.1 for package: ambari-server-2.7.3.0-139.x86_64 --> Finished Dependency Resolution Error: Package: ambari-server-2.7.3.0-139.x86_64 (ambari-2.7.3.0) Requires: postgresql-server >= 8.1 You could try using --skip-broken to work around the problem ** Found 4 pre-existing rpmdb problem(s), 'yum check' output follows: bea-stax-api-1.2.0-9.el7.noarch has missing requires of jpackage-utils bea-stax-api-1.2.0-9.el7.noarch has missing requires of jpackage-utils stax2-api-3.1.1-10.el7.noarch has missing requires of jpackage-utils tomcat-servlet-3.0-api-7.0.76-7.el7_5.noarch has missing requires of jpackage-utils 根據 下面四行所說 缺少 jpackage-utils 。轉回本地源 yum -y install jpackage-utils Error: Package: ambari-server-2.7.3.0-139.x86_64 (ambari-2.7.3.0) Requires: postgresql-server >= 8.1 說明postgresql 版本過低 或者沒有安裝 先 yum-y update postgresql-server 根據反饋選擇 安裝還是升級 2、搭建hdp過程中修改了各節點主機名，導致在進行主機確認時，無法識別 解決辦法： 重新安裝ambari，將ambari相關的檔案，程式都刪除了（除了原始碼包），否則認證的時候無法成功 1、 通過ambari將叢集中的所用元件都關閉 2、 關閉ambari-server，ambari-agent 3、清除瀏覽器的快取 4，yum刪除所有Ambari元件 5、刪除除原始碼包外的所有ambari相關檔案 6、清理資料庫 3、在對主機進行檢查認證時(常規報錯) EOF occurred in violation of protocol (_ssl.c:618) ERROR 2020-07-09 10:35:24,213 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions. ambari openssl 版本問題：SSLError: Failed to connect. Please check openssl library versions.

1.檢查os openssl版本，如果低於 openssl-1.0.1e-16.el6.x86_64 版本，請更新。 [root@node-1 ~]# rpm -qa | grep openssl openssl-1.0.1e-57.el6.x86_64 openssl-devel-1.0.1e-57.el6.x86_64 更新openssl [root@node-1 ~]# yum -y update openssl 重啟ambari-server ambari-server restart 2.若不行， 編輯 /etc/python/cert-verification.cfg 配置檔案，將 [https] 節的 verify 項設為禁用： vim /etc/python/cert-verification.cfg verify=disable 修改/etc/ambari-agent/conf/ambari-agent.ini，在 vim /etc/ambari-agent/conf/ambari-agent.ini [security]新增下面內容 ssl_verify_cert=0 force_https_protocol=PROTOCOL_TLSv1_2 重啟ambari-agent ambari-agent restart 3、安裝服務時報錯 javax.net.ssl.SSLHandshakeException:ClientrequestedprotocolTLSv1notenabledornotsupported 搭建的java jre配置問題 vim $JAVA_HOME/jre/lib/security/java.security 禁用、刪除3DES_EDE_CBC即可，無需新增 TLSv1 修改完成後重啟JAVA程序 （不行的話就重啟伺服器） 5、安裝HDFSclient報錯 排查發現缺少依賴包： 解決辦法：安裝依賴包 http://mirror.centos.org/centos/7/os/x86_64/Packages/libtirpc-0.2.4-0.16.el7.x86_64.rpm http://mirror.centos.org/centos/7/os/x86_64/Packages/libtirpc-devel-0.2.4-0.16.el7.x86_64.rpm rpm -ivh libtirpc-0.2.4-0.16.el7.x86_64.rpmlibtirpc-devel-0.2.4-0.16.el7.x86_64.rpm 報錯 檢視 /var/log/ambari-server/ambari-server.log日誌
