1.下载CM启动文件
[root@ip-172-31-23-107 ec2-user]# wget http://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin

2. 关闭SELINX
[root@ip-172-31-23-107 ec2-user]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
3.关闭防火墙
[root@ip-172-31-23-107 ec2-user]# chkconfig iptables off
4.重启服务器，使2-3步修改生效
5.安装
修改cloudera-manager-installer.bin的权限，并以root用户执行
发生错误，查看日志：
[root@ip-10-248-41-177 ec2-user]# vi /var/log/cloudera-manager-installer/2.install-oracle-j2sdk1.7.log
Failed to set locale, defaulting to C
Loaded plugins: fastestmirror, security
Determining fastest mirrors
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
修改文件“/etc/yum.repos.d/epel.repo”， 将baseurl的注释取消， mirrorlist注释掉。即可。
5.安装向导走完。最好进入CM界面：54.187.193.80:7180
6.在CM界面中遇到ec2-user的问题，
- Edit the /etc/ssh/sshd_config file and change the line that says “PermitRootLogin forced-commands-only” to “PermitRootLogin without-password”.
- Restart the sshd server with “service sshd restart”.
- Edit the /root/.ssh/authorized_keys file. This file should have one line only. It starts by “echo” or “command … sleep 10;” then you can see “ssh-rsa [big long key]”. Remove the text from the beginning of the line until where it says “ssh-rsa”.
[root@ip-10-248-41-177 ec2-user]# vi /etc/ssh/sshd_config
#PermitRootLogin yes -->
PermitRootLogin without-password
[root@ip-10-248-41-177 ec2-user]# /etc/init.d/sshd reload
[root@ip-10-248-41-177 ec2-user]# vi ~/.ssh/authorized_keys
7.安装过程中，发现卡在“Acquiring installation lock...”
[root@ip-10-248-41-177 ~]# rm -rf /tmp/.scm_prepare_node.lock
并重试
8.发现如下错误：
>>[19/Nov/2013 15:00:55 +0000] 1922 HTTPServer Thread-2 _cplogging ERROR [19/Nov/2013:15:00:55] ENGINE Error in HTTP server: shutting down

>>error: No socket could be created on ('NexusHadoopVM', 9000) -- [Errno 99] Cannot assign requested address
不知道为什么，AWS把HOSTNAME搞错了。所有的机器的hostname都一样：
python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())'
都返回:
ip-10-248-41-177.us-west-2.compute.internal 10.248.41.177
用hostname ip-172-31-23-107.us-west-2.compute.internal改正确
9.在安装oozie时发现：
Failed to create Oozie database.
日志错误信息：
Error: DB schema exists Stack trace for the error was (for debug purposes):
--------------------------------------
java.lang.Exception: DB schema exists
at org.apache.oozie.tools.OozieDBCLI.validateDBSchema(OozieDBCLI.java:877)

at org.apache.oozie.tools.OozieDBCLI.run(OozieDBCLI.java:127)

rm -rf /var/lib/oozie/*
