环境：Vmware+Ubuntu16
配置网络
将网络配置为静态
更改为合适的hostname
将hostname和本机ip绑定
ping 自己测试下
关闭防火墙
我们知道，在安装hadoop的时候会打开很多端口，由于是小打小闹，所以不必去一个端口一个端口的开放，我们就直接全部开放，那么关闭防火墙就可以了
注意，防火墙的服务名不是firewalls而是iptables
下面我们关闭防火墙
为了防止防火墙在重启电脑的时候重新启动，那么我们需要执行关闭防火墙自启动功能
sudo ufw disable
安装jdk
安装JDK（至少需要Oracle JDK7及以上）
java -version
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java7-set-default
通过命令java -version查看是否安装成功
然后添加JAVA_HOME和Path，在我这是在~/.bashrc里加入：
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jrelib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
echo "PATH=$PATH" >> ~/.zshrc
//我用的是zsh，所以更改的是.zsh而不是.bashrc
保存后source ~/.zshrc，通过命令echo $JAVA_HOME查看是否成功。
####安装Mysql并设置远程登录
1. 开启远程访问 参考：http://blog.csdn.net/u012348345/article/details/51226937
2. 配置
service mysql stop #停止服务
vi /etc/mysql/conf.d/mysql_cloudera_manager.cnf #添加配置文件
写入
[mysqld]
transaction-isolation = READ-COMMITTED
Disabling symbolic-links is recommended to prevent assorted security risks;
to do so, uncomment this line:
symbolic-links = 0
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
expire_logs_days = 10
max_binlog_size = 100M
log_bin should be on a disk with enough free space. Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your system
and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/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
sql_mode=STRICT_ALL_TABLES
####安装ntp
sudo apt-get install ntp，重启服务sudo service ntp restart
#安装Cloudera Manager
####添加CDH5 Repository
Ubuntu Xenial (16.04)： wget https://archive.cloudera.com/cm5/ubuntu/xenial/amd64/cm/cloudera.list -O /etc/apt/sources.list.d/cloudera.list
Ubuntu Trusty (14.04)： wget https://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/cloudera.list -O /etc/apt/sources.list.d/cloudera.list
Ubuntu Precise (12.04)： wget https://archive.cloudera.com/cm5/ubuntu/precise/amd64/cm/cloudera.list -O /etc/apt/sources.list.d/cloudera.list
Ubuntu Lucid (10.04)： wget https://archive.cloudera.com/cm5/ubuntu/lucid/amd64/cm/cloudera.list -O /etc/apt/sources.list.d/cloudera.list
####添加Key
curl -s http://archive.cloudera.com/cdh5/ubuntu/xenial/amd64/cdh/archive.key | sudo apt-key add -
> 如果是Trusty的操作系统，还需要以下一个附加步骤：
创建一个新文件/etc/apt/preferences.d/cloudera.pref
内如如下：
Package: *
Pin: release o=Cloudera, l=Cloudera
Pin-Priority: 501
