ubuntu14.04自建局域网源在线安装CDH5.6.0

Posted 2023-02-22 洽洽老大

背景：要搭建一个可以添加节点的cloudera集群，但内部网络访问不了cloudera，能访问的主机访问速度也特别慢。
实现方式：搭建一个内部的软件源，采用官网第二种方式安装

1. 搭建CDH源服务器

源服务器地址：192.168.10.136
可以连接外网

下载以下包

1.1. cloudera-manager相关包（下载地址：https://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/pool/contrib/e/enterprise/）

• cloudera-manager-agent_5.6.0-1.cm560.p0.54~trusty-cm5_amd64.deb
• cloudera-manager-daemons_5.6.0-1.cm560.p0.54~trusty-cm5_all.deb
• cloudera-manager-server_5.6.0-1.cm560.p0.54-trusty-cm5_all.deb

1.2. oracle-j2sdk1.7(下载地址：https://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/pool/contrib/o/）

1.3. cdh安装包parcel（下载地址：https://archive.cloudera.com/cdh5/parcels/5.6.0/）

• CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel
• CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha1
• manifest.json

1.4. 其他的依赖包(下载方式：可以用一台可以连接外网的主机，用apt-get install下载安装，下载完后在/var/cache/apt/archives里找到）

• lsb-base psmisc bash libsasl2-modules zlib1g libsqlite3-0 libfuse2 fuse rpcbind libxslt1.1 libsasl2-modules-gssapi-mit libmysql-java python-urllib3 python-mysqldb mariadb-server-5.5

安装源服务器

1 创建目录/data/soft/pool //设立安装源路径

拷贝cloudera-manager相关包、oracle-j2sdk1.7和其他的依赖包到/data/soft/pool

2 安装dpkg-dev

安装dpkg-dev，并执行dpkg-scanpackages 扫描依赖包并生成依赖关系gz包：

sudo apt-get install  dpkg-dev -y

生成Packages.gz

root@192.168.10.136:/data# dpkg-scanpackages soft/pool | gzip > soft/Packages.gz 一定要这么写，不然有错误

3 创建目录/data/soft/cloudera,将cdh安装包parcel和manifest.json复制到/data/soft/cloudera/下

4 安装apache2

sudo apt-get install apache2

建立软链接使其他主机访问

cd /var/www/html

ln -s /data

访问196.168.10.136/data, 可以查看到soft目录即表示apache安装配置成功

2. 集群安装(用root用户安装)

三台机器的ip和名字为

192.168.10.236 hadoop-1 (内存16G) cloudera-manager-server
192.168.10.237 hadoop-2 (内存16G)
192.168.10.238 hadoop-3 (内存8G)

2.1 配置各节点允许root ssh登陆

sudo vi /etc/ssh/sshd_config

找到PermitRootLogin no一行，改为PermitRootLogin yes

sudo service ssh restart

2.1 配置主节点root免密钥陆其他节点

在hadoop-1上执行ssh-keygen -t rsa -P ”生成无密码密钥对
将公钥添加到认证文件中：cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
将认证文件拷贝到hadoop-2和hadoop-3的/root/.ssh/目录下，使主节点免密码访问从节点

2.2 配置/etc/hosts（各个节点都要）

192.168.10.236 hadoop-1
192.168.10.237 hadoop-2
192.168.10.238 hadoop-3

2.3 各节点设置安装源

在/etc/apt/sources.list.d添加innersource.list

vim /etc/apt/sources.list.d/innersources.list

输入以下内容

deb http://192.168.10.136/data soft/

保存后刷新源（apt-get update)

2.3 各节点安装oracle-j2sdk1.7

apt-get install oracle-j2sdk1.7

update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-oracle-cloudera/bin/java 300
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-7-oracle-cloudera/bin/javac 300
update-alternatives --install /usr/bin/jps jps /usr/lib/jvm/java-7-oracle-cloudera/bin/jps 300

2.4 主节点（即hadoop-1）安装和配置数据库(MariaDB 5.5)

apt-get install mariadb-server-5.5

vim /etc/mysql/my.cnf

下面是官方建议配置，必须改的有

transaction-isolation = READ-COMMITTED
binlog_format = mixed

其他的没所谓

[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/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

重启服务service mysql restart

创建相关数据库

进入mysql命令行：$ mysql -u root -p
进入mysql命令行后，直接复制下面的整段话并粘贴：
create database amon DEFAULT CHARACTER SET utf8;
grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'amon_password';
grant all on amon.* TO 'amon'@'CDH' IDENTIFIED BY 'amon_password';
create database smon DEFAULT CHARACTER SET utf8;
grant all on smon.* TO 'smon'@'%' IDENTIFIED BY 'smon_password';
grant all on smon.* TO 'smon'@'CDH' IDENTIFIED BY 'smon_password';
create database rman DEFAULT CHARACTER SET utf8;
grant all on rman.* TO 'rman'@'%' IDENTIFIED BY 'rman_password';
grant all on rman.* TO 'rman'@'CDH' IDENTIFIED BY 'rman_password';
create database hmon DEFAULT CHARACTER SET utf8;
grant all on hmon.* TO 'hmon'@'%' IDENTIFIED BY 'hmon_password';
grant all on hmon.* TO 'hmon'@'CDH' IDENTIFIED BY 'hmon_password';
create database hive DEFAULT CHARACTER SET utf8;
grant all on hive.* TO 'hive'@'%' IDENTIFIED BY 'hive_password';
grant all on hive.* TO 'hive'@'CDH' IDENTIFIED BY 'hive_password';
create database oozie DEFAULT CHARACTER SET utf8;
grant all on oozie.* TO 'oozie'@'%' IDENTIFIED BY 'oozie_password';
grant all on oozie.* TO 'oozie'@'CDH' IDENTIFIED BY 'oozie_password';
create database metastore DEFAULT CHARACTER SET utf8;
grant all on metastore.* TO 'hive'@'%' IDENTIFIED BY 'hive_password';
grant all on metastore.* TO 'hive'@'CDH' IDENTIFIED BY 'hive_password';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'gaoying' WITH GRANT OPTION;
flush privileges;

2.5 主节点安装Cloudera Manager Server

apt-get install cloudera-manager-daemons cloudera-manager-server 

log目录： /var/log/cloudera-scm-server/cloudera-scm-server.log

2.6 Cloudera Manager Server配置数据库(主节点)

/usr/share/cmf/schema/scm_prepare_database.sh mysql -uroot -p --scm-host loclhost scm scm scm_password

2.7 启动server服务(主节点)

service cloudera-scm-server start

如果没启动成功，可查看/var/log/cloudera-scm-server/cloudera-scm-server.log


2.8 手动在各节点安装cloudera manager agent

apt-get install  lsb-base psmisc bash libsasl2-modules zlib1g libsqlite3-0 libfuse2 fuse rpcbind libxslt1.1 libsasl2-modules-gssapi-mit libmysql-java python-urllib3 python-mysqldb cloudera-manager-daemons cloudera-manager-agent

3 使用cloudera manager wizard完成安装

在parcels的more options
添加Remote Parcel Repository URLS

http://192.168.10.136/data/soft/cloudera/

把自建的内部源地址输入custom repository

后续部分参照Ubuntu14.04离线安装CDH5.6.0

3 添加节点

1. 修改所有主机的/etc/hosts
2. 在新主机上配置内部源，手动下载lsb-base psmisc bash libsasl2-modules zlib1g libsqlite3-0 libfuse2 fuse rpcbind libxslt1.1 libsasl2-modules-gssapi-mit libmysql-java python-urllib3 python-mysqldb cloudera-manager-daemons cloudera-manager-agent
3. 通过cloudera manager wizard完成后续安装
