第二、Linux操作系统安装
1、配置内核参数(所有节点)
# cat /etc/sysctl.conf
##内核默认参数
kernel.sysrq = 0
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
##打开文件数参数(20*1024*1024)
fs.file-max= 20971520
##WEB Server参数
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_fin_timeout=30
net.ipv4.tcp_keepalive_time=1200
net.ipv4.ip_local_port_range = 1024 65535
net.ipv4.tcp_rmem=4096 87380 8388608
net.ipv4.tcp_wmem=4096 87380 8388608
net.ipv4.tcp_max_syn_backlog=8192
net.ipv4.tcp_max_tw_buckets = 5000
##TCP补充参数
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.netdev_max_backlog = 262144
net.core.somaxconn = 262144
net.ipv4.tcp_max_orphans = 3276800
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
##禁用ipv6
net.ipv6.conf.all.disable_ipv6 =1
net.ipv6.conf.default.disable_ipv6 =1
##swap使用率优化
vm.swappiness=0
执行以下命令使参数生效:
# sysctl -p
2、配置打开文件数(所有节点)
# vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

3、关闭防火墙(所有节点)
# service iptables stop
# chkconfig iptables off

关闭SELINUX
# vi /etc/selinux/config
修改SELINUX=enforcing为 SELINUX=disabled
4、时间同步(所有节点)
#/usr/sbin/ntpdate -us 172.27.5.123;hwclock -w;
6、关闭大叶内存(所有节点)
#cat << EOF >> /etc/rc.d/rc.local
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
EOF
7、系统默认语言(所有节点)
#env |grep LANG

如果不是en_US.UTF-8，请修改/etc/locale.conf中的LANG为”en_US.UTF-8”

注意:优化完成后，必须重启所有主机
安装额外依赖包：
yum -y install libxslt-devel psmisc python-lxml
第三、前置环境
参考链接：https://www.cloudera.com/documentation/enterprise/release-notes/topics/rg_vd.html
1、CDH安装包下载
http://archive.cloudera.com/cdh5/parcels/5.12/
下载对应操作系统的3个文件
CDH-5.12.1-1.cdh5.12.1.p0.3-el6.parcel
CDH-5.12.1-1.cdh5.12.1.p0.3-el6.parcel.sha1
manifest.json
2、CM安装包下载
从http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5.12.1/RPMS/x86_64/下载所有包
上传下载的包至yum服务器，并搭建本地yum源server,实现访问http://172.27.10.200/cdh/ 如下效果：

repo文件配置
#cat /etc/yum.repos.d/cm.repo
[cm]
name=cm5.12
baseurl=http://172.27.10.200/cdh/
enabled=1
gpgcheck=0
priority=1
3、JDBC驱动下载与安装
参考链接:
http://www.cloudera.com/documentation/cdh/5-1-x/CDH5-Installation-Guide/cdh5ig_jdbc_driver_install.html
1)、下载JDBC驱动
# mkdir -p /usr/share/java && cd /usr/share/java
# wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.44.tar.gz
# tar zxf mysql-connector-java-5.1.44.tar.gz
# cp mysql-connector-java-5.1.44/mysql-connector-java-5.1.44-bin.jar .
# mv mysql-connector-java-5.1.44-bin.jar mysql-connector-java.jar
# chmod +x mysql-connector-java.jar
4、安装JDK环境(每个节点)
#yum -y install jdk oracle-j2sdk1.7
5、mariadb部署(cdh07)
参考链接: https://www.cloudera.com/documentation/enterprise/5-5-x/topics/install_cm_mariadb.html
1)、数据库安装
#yum -y install mariadb-server
2)、my.cnf配置
# cp /etc/my.cnf /etc/my.cnfbak
#cat /etc/my.cnf
[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
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/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

# systemctl enable mariadb
# systemctl list-unit-files | grep mariadb

2)、创建数据库
创建Hive数据库:
mysql >create database hive512 default character set latin1;
字符必须为拉丁(latin1),如果uft8可能会报错Specified key was too long; max key length is 767 bytes
mysql >grant all privileges on hive512.* to hive512@localhost identified by '123456';
mysql >grant all privileges on hive512.* to hive512@'172.27.%' identified by '123456';
mysql >flush privileges;
创建report数据库
mysql >create database report512 character set utf8;
mysql >grant all privileges on report512.* to report512@localhost identified by '123456';
mysql >grant all privileges on report512.* to report512@'172.27.%' identified by '123456';
mysql >flush privileges;
创建monitor数据库
mysql>create database monitor512 character set utf8;
mysql>grant all privileges on monitor512.* to monitor512@localhost identified by '123456';
mysql>grant all privileges on monitor512.* to monitor512@'172.27.%' identified by '123456';
mysql>flush privileges;
创建sentry数据库
mysql>create database sentry512 character set utf8;
mysql>grant all privileges on sentry512.* to sentry512@localhost identified by '123456';
mysql>grant all privileges on sentry512.* to sentry512@'172.27.%' identified by '123456';
mysql>flush privileges;
第四、部署CDM-manager
1、CDM部署
#yum install cloudera-manager-server
2、创建cmf数据库
mysql >create database cmf character set utf8;
mysql >grant all privileges on cmf.* to cmf@localhost identified by 'cmf123456';
mysql >grant all privileges on cmf.* to cmf@'172.27.%' identified by 'cmf123456';
mysql >flush privileges;
3、修改配置文件
# cp /etc/cloudera-scm-server/db.properties /etc/cloudera-scm-server/db.propertiesbak
# vi /etc/cloudera-scm-server/db.properties

4、启动服务
# /etc/init.d/cloudera-scm-server restart
# /etc/init.d/cloudera-scm-server status

至此cdm-server部署完成
第五、部署cdm-agent
1、agent安装
# yum -y install cloudera-manager-daemons cloudera-manager-agent
2、修改客户端配置文件config.ini
#cp /etc/cloudera-scm-agent/config.ini /etc/cloudera-scm-agent/config.inibak
#sed -i '/server_host/s/localhost/cdh01.localdomain/' /etc/cloudera-scm-agent/config.ini
3、启动客户端
# /etc/init.d/cloudera-scm-agent restart
# /etc/init.d/cloudera-scm-agent status

至此cdm-agent部署完成
第六、CDH部署
1、上传文件
上传文件到windcdh01节点的/opt/cloudera/parcel-repo目录下
#cd /opt/cloudera/parcel-repo
# mv CDH-5.10.1-1.cdh5.10.1.p0.10-el6.parcel.sha1 CDH-5.10.1-1.cdh5.10.1.p0.10-el6.parcel.sha
如果不重命名CDH会识别不了版本
2、检查目录并授权
# cd /opt/cloudera/parcel-repo
# chown -R cloudera-scm.cloudera-scm /opt/cloudera/parcel-repo

检查文件(注意用户名和权限)
至此CDH/CDM部署完成
第七、利用web部署hadoop
1、上传文件
http://172.27.9.191:7180
账号:admin 密码:admin







只要文件路径配置正确,已下载就是100%,如果出现进度条1%，必须检查文件和客户端配置


检查结果要仔细看下，如果有异常，按照提示解决即可。


这里选择安装组件:

分配角色，注意保障节点的组件数均衡：
