　　如果大家&＃xff0c;在启动的时候&＃xff0c;比如遇到如下问题&＃xff0c;则

　　明明已经授权了啊&＃xff0c;怎么被拒绝&＃xff0c;纳尼&＃xff1f;&＃xff1f;&＃xff1f;

　　解决办法

　　然后&＃xff0c;再来这样&＃xff0c;就可以了。

　　注意&＃xff0c;在此之前。

　　ubuntucmbigdata1机器上&＃xff0c;则需要执行

bigdata&＃64;ubuntucmbigdata1:~$ sudo /usr/share/cmf/schema/scm_prepare_database.sh mysql scm scm scm_password[sudo] password for bigdata:
Sorry, try again.
[sudo] password for bigdata:

[ main] DbCommandExecutor INFO Successfully connected to database.
All done, your SCM database is configured correctly!

bigdata&＃64;ubuntucmbigdata1:~$ sudo service cloudera-scm-server start
[sudo] password for bigdata:
Starting cloudera-scm-server: * cloudera-scm-server started

bigdata&＃64;ubuntucmbigdata1:~$

bigdata&＃64;ubuntucmbigdata1:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata:
Starting cloudera-scm-agent: * cloudera-scm-agent started

bigdata&＃64;ubuntucmbigdata1:~$

　　然后&＃xff0c;在ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上

bigdata&＃64;ubuntucmbigdata2:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata:
Starting cloudera-scm-agent: * cloudera-scm-agent started

bigdata&＃64;ubuntucmbigdata2:~$

bigdata&＃64;ubuntucmbigdata3:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata:
Starting cloudera-scm-agent: * cloudera-scm-agent started

bigdata&＃64;ubuntucmbigdata3:~$

bigdata&＃64;ubuntucmbigdata4:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata:
Starting cloudera-scm-agent: * cloudera-scm-agent started

bigdata&＃64;ubuntucmbigdata4:~$

　　这是&＃xff0c;因为。我之前前面4台机器都没有启动服务&＃xff0c;所以会是如下。四个自动会勾选。

　　有时候会是如下&＃xff0c;

　　那是因为&＃xff0c;ubuntucmbigdata3这台的服务没启动。

　　一般&＃xff0c;若大家按照我本博文的顶部&＃xff0c;把每台机器相应的服务&＃xff0c;都启动起来了的话&＃xff0c;则是如下&＃xff08;是最好的&＃xff09;

　　或者

　　如果你的本地里&＃xff0c;已经安装好了&＃xff0c;比如我这里的jdk1.7&＃xff0c;则这里就不需要勾选&＃xff0c;不然会报错后面 &＃xff08;但是&＃xff0c;若大家通过我的bin方式来安装的话&＃xff0c;是直接没有安装任何jdk的&＃xff0c;直接是上面一样&＃xff0c;勾选&＃xff0c;它会自动好jdk&＃xff09;

http://ubuntucmbigdata1:7180/cmf/express-wizard/wizard#step&＃61;hostCredentialsStep

　　由此可见&＃xff0c;我的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4&＃xff0c;是clouder manager agent。

　　如下的界面&＃xff0c;是因为&＃xff0c;我提前没有安装好&＃xff0c;所以是在线此刻安装的。

　　两种方式都可以

　　或者&＃xff08;以下&＃xff0c;是因为&＃xff0c;我已经先提前在这一步安装好了&＃xff0c;所以是如下的界面&＃xff09;

　　若出现如下问题&＃xff0c;则

bigdata&＃64;ubuntucmbigdata1:~$ sudo echo 0 > /proc/sys/vm/swappiness
-bash: /proc/sys/vm/swappiness: Permission denied
bigdata&＃64;ubuntucmbigdata1:~$ su root

bigdata&＃64;ubuntucmbigdata4:~$ su root
Password:
root&＃64;ubuntucmbigdata4:/home/bigdata# sudo echo 0 > /proc/sys/vm/swappiness
root&＃64;ubuntucmbigdata4:/home/bigdata#

　然后&＃xff0c;接下来&＃xff0c;这一步&＃xff0c;其实跟我另外写的一篇用ambari是一样的。

Ambari安装之部署3个节点的HA分布式集群

　　最后&＃xff0c;我的初步安装是

　　其实&＃xff0c;也跟我写的这篇博客也类似

Cloudera Manager安装之利用parcels方式安装3或4节点集群&＃xff08;包含最新稳定版本或指定版本的安装&＃xff09;&＃xff08;添加服务&＃xff09;&＃xff08;CentOS6.5&＃xff09;&＃xff08;五&＃xff09;

　　这里&＃xff0c;我的数据库设置是在下面的博客就已经设置好了的。

Ubuntu14.04下完美安装cloudermanage多种方式&＃xff08;图文详解&＃xff09;&＃xff08;博主推荐&＃xff09;

　　若是centos系统&＃xff0c;则是可以直接

[root&＃64;cmbigdata1 ~]# yum install mysql-connector-java
Is this ok [y/N]: y

　　就好了。

　　但是&＃xff0c;在ubuntu系统里&＃xff0c;

root&＃64;ubuntucmbigdata1:/home/bigdata# apt-get install libmysql-java

　　则会失败。

　　解决办法1

root&＃64;ubuntucmbigdata1:~# sudo /etc/init.d/mysql start

　　查看你的mysql服务启动没。

　　解决办法2
