GiveMeMoreTime

在实践了CDH6的离线部署之后，发现Cloudera的官方教程是基于CDH5.10的。同时，CDH6的内存占用比较高，我的机器有点遭不住，所以又把CDH5的部署实施走了一遍。

模板部署

1. 安装CentOS7.10，并完成yum升级；
2. 所有主机时间与阿里云时间服务器同步；
3. 关闭selinux和firewalld；
4. 安装JDK和mysql-connect；

[root@localhost ~]# wget https://repo.huaweicloud.com/java/jdk/8u202-b08/jdk-8u202-linux-x64.rpm
[root@localhost ~]# yum localinstall jdk-8u202-linux-x64.rpm
[root@localhost ~]# mv mysql-connector-java-5.1.39-bin.jar /usr/share/java/mysql-connector-java.jar 

5. 关闭透明大页；

[root@localhost ~]# vim /etc/rc.d/rc.local

# 在最后一行添加如下内容
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi

if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

# 赋予rc.local具有可执行权限
[root@localhost ~]# chmod +x /etc/rc.d/rc.local
[root@localhost ~]# sh /etc/rc.d/rc.local

# 检查
[root@localhost ~]# cat /sys/kernel/mm/transparent_hugepage/defrag
always madvise [never]
[root@localhost ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]

6. 调整swap策略

[root@localhost ~]# echo 10 > /proc/sys/vm/swappiness
[root@localhost ~]# echo vm.swappiness = 10 >> /etc/sysctl.conf

7. 修改文件句柄数

[root@localhost ~]# vim /etc/security/limits.conf
# 添加如下内容
* soft nofile 100000
* hard nofile 100000

8. 收尾

[root@localhost ~]# sys-unconfig

9. 下载CM和CDH

CM下载地址

CDH下载地址

Agent部署

1. 配置主机ssh信任
2. 安装ansible

# 安装
[root@elephant ~]# yum install -y ansible

[root@elephant ~]# ls

[root@elephant ~]# mkdir client
[root@elephant ~]# mv cloudera-manager-daemons-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm client/
[root@elephant ~]# mv cloudera-manager-agent-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm client/
[root@elephant ~]# tar zcvf client.tar.gz client/

3. 分发

[root@elephant ~]# ansible all -m copy -a 'src=/root/client.tar.gz dest=/root/'
[root@elephant ~]# ansible all -a 'tar zxf /root/client.tar.gz'

4. 安装

[root@elephant ~]# ansible all -a 'yum localinstall /root/client/cloudera-manager-daemons-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm -y'
[root@elephant ~]# ansible all -a 'yum localinstall /root/client/cloudera-manager-agent-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm -y'

# 修改配置文件
[root@elephant ~]# sed -i ':s/localhost/lion/g' /etc/cloudera-scm-agent/config.ini
[root@elephant ~]# ansible lion,tiger,horse,monkey -m copy -a 'src=/etc/cloudera-scm-agent/config.ini dest=/etc/cloudera-scm-agent/'

# 重启服务
[root@elephant ~]# ansible all -a 'systemctl enable cloudera-scm-agent --now'
[root@elephant ~]# ansible all -a 'systemctl restart cloudera-scm-agent'

管理主机部署

1. 安装

[root@elephant ~]# ansible lion -m copy -a 'src=/root/cloudera-manager-server-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm dest=/root/'
[root@elephant ~]# ansible lion -m copy -a 'src=/root/CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel dest=/opt/cloudera/parcel-repo'
[root@elephant ~]# ansible lion -m copy -a 'src=/root/manifest.json dest=/opt/cloudera/parcel-repo'
[root@elephant ~]# ansible lion -a 'yum localinstall /root/cloudera-manager-server-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm -y'

2. 数据库部署

[root@elephant ~]# ansible lion -a 'yum install -y mariadb mariadb-server'
[root@elephant ~]# ssh lion
[root@lion ~]# vim /etc/my.cnf.d/server.cnf
[mysqld]
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
server_id=1

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

[root@lion ~]# systemctl enable mariadb --now

# 导入数据库
[root@lion ~]# mysql -uroot -p < cdh.sql

# 扩展数据库架构和CDH6有区别
[root@lion ~]# cp /usr/share/java/mysql-connector-java.jar /usr/share/cmf/lib/
[root@lion ~]# sh /usr/share/cmf/schema/scm_prepare_database.sh mysql scm scm

# 启动服务
[root@lion parcel-repo]# cd /opt/cloudera/parcel-repo/
[root@lion parcel-repo]# sha1sum CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel | awk '{ print $1 }' > CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel.sha
[root@lion ~]# chkconfig cloudera-scm-server on
[root@lion ~]# systemctl start cloudera-scm-server

# 检查结果
[root@lion ~]# netstat -tlnp |grep 7180

GUI安装

接下来的安装就相对简单了，基本比CDH6简单。
