由于CDH有多个版本，作者不建议单独下载安装，可以通过cloudera-manager-daemons、cloudera-manager-server、cloudera-manager-agent来安装，本文后面会有介绍。
4、如何安装 4.1、设置Host修改Host
root@m1:~# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.10 m1.linuxidc.com m1 192.168.1.11 m2.linuxidc.com m2 192.168.1.12 s1.linuxidc.com s1 192.168.1.13 s2.linuxidc.com s2 # The following lines are desirable for IPv6 capable hosts ff02::1 ip6-allnodes ff02::2 ip6-allrouters 4.2、设置静态IP修改成静态IP地址
root@m1:~# vi /etc/network/interfaces iface wlan0 inet static address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 dns-nameservers 8.8.8.8 4.3、设置Host修改主机名称
root@m1:~# cat /etc/hostname m1.linuxidc.com 4.4、关闭防火墙 root@m1:~# ufw disable 4.5、安装JDK7，CDH5要求至少是Oracle JDK7添加 PPA repository 到系统
root@m1:~# add-apt-repository ppa:webupd8team/java root@m1:~# apt-get update root@m1:~# sudo apt-get upgrade1

过程中会弹出个框，选择YES，因为要下载二进制包，所以可能会慢一些
root@m1:~# apt-get install oracle-java7-installer
将Oracle 7 设置成默认版本
查看当前Java版本
root@m1:~# java -version java version "1.7.0_67" Java(TM) SE Runtime Environment (build 1.7.0_67-b01) Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode) 4.6、安装MySql最新版，CM的数据库我们用My Sql管理 安装Mysql Server，后面在安装Cloudera Manager的时候会用到，如果你要使用PostGreSQL ，可以跳过这一步 (4.6-4.8)。
在主机上使用apt-get安装My Sql，安装过程中会有提示，一直接回车就可以 （4台机器都要执行）
root@m1:~# apt-get install mysql-server 4.6.2、修改MySql配置，方便CM使用 4.6.2.1、配置MySql的监听地址对MySQL的配置项进行修改，先备份，找到“bind-address = 127.0.0.1”这一行，然后注释掉，改成“bind-address = 0.0.0.0”
root@m1:~# cp /etc/mysql/my.cnf /etc/mysql/my.cnf.bak root@m1:~# vi /etc/mysql/my.cnf #bind-address = 127.0.0.1 bind-address = 0.0.0.0 4.6.2.2、配置MySql的其他配置，为了CM使用MySql配置中，其中对于Cloudera的支持，可以参考官方描述
[client] default-character-set=utf8 [mysqld] transaction-isolation=READ-COMMITTED # Disabling symbolic-links is recommended to prevent assorted security risks; # to do so, uncomment this line: # symbolic-links=0 character-set-server=utf8 key_buffer = 16M key_buffer_size = 32M max_allowed_packet = 32M thread_stack = 256K thread_cache_size = 64 query_cache_limit = 8M query_cache_size = 64M query_cache_type = 1 max_connections = 550 # log-bin should be on a disk with enough free space # NOTE: replace '/x/home/mysql/logs/binary' below with # an appropriate path for your system. log-bin=/x/home/mysql/logs/binary/mysql_binary_log # For MySQL version 5.1.8 or later. Comment out binlog_format for older versions. binlog_format = mixed read_buffer_size = 2M read_rnd_buffer_size = 16M sort_buffer_size = 8M join_buffer_size = 8M # InnoDB settings innodb_file_per_table = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 64M innodb_buffer_pool_size = 4G innodb_thread_concurrency = 8 innodb_flush_method = O_DIRECT innodb_log_file_size = 512M [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid 4.7、创建后面在CM中会使用的数据库 root@m1:~# mysql -u root -p Enter password: Welcome to the MySQL monitor.
