kudu安装部署

安装部署节点规划

节点

kudu-master

kudu-tserver

node01

node02

node03

配置本地Yum的Repository

下载kudu安装yum源。并配置安装yum源

[root@hadoop03 soft]# wget http://archive.cloudera.com/cdh5/repo-as-tarball/5.14.0/cdh5.14.0-centos6.tar.gz

解压yum源文件到指定目录

[root@hadoop03 soft]# tar zxvf cdh5.14.0-centos6.tar.gz -C /usr/local/

镜像源是centos当中下载相关软件的地址,我们可以通过制作我们自己的镜像源指定我们去哪里下载kudu的rpm包,这里我们使用httpd这个软件来作为服务端,启动httpd的服务来作为我们镜像源的下载地址 这里我们选用第三台机器作为镜像源的服务端node3机器上执行以下命令:

[root@hadoop03 soft]# yum install -y httpd

[root@hadoop03 soft]# service httpd start

[root@hadoop03 soft]# cd /etc/yum.repos.d

[root@hadoop03 yum.repos.d]# vim localimp.repo

[localimp]

name=localimp

baseurl=http://node03/cdh5.14.0

gpgcheck=0

enabled=1

  

将node3上制作好的localimp配置文件发放到所有需要kudu的节点上去

[root@hadoop03 yum.repos.d]# scp -r localimp.repo node01:$PWD

[root@hadoop03 yum.repos.d]# scp -r localimp.repo node02:$PWD

创建apache httpd的读取连接

[root@hadoop03 ~]# ln -s /usr/local/cdh/5.14.0 /var/www/html/cdh5.14.0

页面访问本地yum源,出现这个界面表示本地yum源制作成功 访问http://node03/cdh5.14.0

安装kudu

使用yum命令,在不同的服务器下载对应的服务

[root@hadoop01 ~]# yum install -y kudu kudu-master kudu-tserver kudu-client0 kudu-client-devel

[root@hadoop02 ~]# yum install -y kudu kudu-master kudu-tserver kudu-client0 kudu-client-devel

[root@hadoop03 ~]# yum install -y kudu kudu-master kudu-tserver kudu-client0 kudu-client-devel

命令说明:

yum install kudu # Kudu的基本包

yum install kudu-master # KuduMaster

yum install kudu-tserver # KuduTserver

yum install kudu-client0 #Kudu C ++客户端共享库

yum install kudu-client-devel # Kudu C ++客户端共享库 SDK

   

配置master和tserver节点

[root@hadoop01 kudu]# cd /etc/kudu/conf/

   

修改master.gflagfile

[root@hadoop01 conf]# vim master.gflagfile

# cat /etc/kudu/conf/master.gflagfile

# Do not modify these two lines. If you wish to change these variables,

# modify them in /etc/default/kudu-master.

--fromenv=rpc_bind_addresses

--fromenv=log_dir

--fs_wal_dir=/export/servers/kudu/master

--fs_data_dirs=/export/servers/kudu/master

--master_addresses=node01:7051,node02:7051,node03:7051

   

修改tserver.gflagfile

[root@hadoop01 conf]# vim tserver.gflagfile

# Do not modify these two lines. If you wish to change these variables,

# modify them in /etc/default/kudu-tserver.

--fromenv=rpc_bind_addresses

--fromenv=log_dir

--fs_wal_dir=/export/servers/kudu/tserver

--fs_data_dirs=/export/servers/kudu/tserver

--tserver_master_addrs=node01:7051,node02:7051,node03:7051

   

修改 /etc/default/kudu-master

[root@hadoop01 conf]# vim /etc/default/kudu-master

export FLAGS_log_dir=/var/log/kudu

#每台机器的master地址要与主机名一致,这里是在node01

export FLAGS_rpc_bind_addresses=node01:7051

   

修改 /etc/default/kudu-tserver

[root@hadoop01 conf]# vim /etc/default/kudu-tserver

export FLAGS_log_dir=/var/log/kudu

#每台机器的tserver地址要与主机名一致,这里是在node01

export FLAGS_rpc_bind_addresses=node01:7050

   

修改完成后的上述配置文件分发到其他服务器上

[root@hadoop01 default]# cd /etc/kudu/conf

[root@hadoop01 conf]# scp -r master.gflagfile tserver.gflagfile node02:$PWD

[root@hadoop01 conf]# scp -r master.gflagfile tserver.gflagfile node03:$PWD

   

[root@hadoop01 conf]# cd /etc/default/

[root@hadoop01 default]# scp -r kudu-master kudu-tserver node02:$PWD

[root@hadoop01 default]# scp -r kudu-master kudu-tserver node03:$PWD

   

修改node02服务器上的配置文件

[root@hadoop02 conf]# cd /etc/default/

[root@hadoop02 default]# vim kudu-master

export FLAGS_log_dir=/var/log/kudu

export FLAGS_rpc_bind_addresses=node02:7051

   

[root@hadoop02 default]# vim kudu-tserver

export FLAGS_log_dir=/var/log/kudu

export FLAGS_rpc_bind_addresses=node02:7050

   

修改node03服务其上的配置文件

[root@hadoop03 ~]# cd /etc/default/

[root@hadoop03 default]# vim kudu-master

export FLAGS_log_dir=/var/log/kudu

export FLAGS_rpc_bind_addresses=node03:7051

   

[root@hadoop03 default]# vim kudu-tserver

export FLAGS_log_dir=/var/log/kudu

export FLAGS_rpc_bind_addresses=node03:7050

   

在三台服务器上分别创建配置存储数据目录并修改权限

[root@hadoop01 default]# mkdir -p /var/lib/kudu

[root@hadoop01 default]# chmod –R kudu:kudu /var/lib/kudu

   

[root@hadoop02 default]# mkdir -p /var/lib/kudu

[root@hadoop02 default]# chmod –R kudu:kudu /var/lib/kudu

   

[root@hadoop03 default]# mkdir -p /var/lib/kudu

[root@hadoop03 default]# chmod –R kudu:kudu /var/lib/kudu

   

   

注意

kudu默认用户就是KUDU,所以需要将/var/lib/kudu权限修改成kudu

[root@hadoop01 conf]# chown -R kudu:kudu /var/lib/kudu

   

(如果使用的是普通的用户,那么最好配置sudo权限)/etc/sudoers文件中添加:

   

kudu集群启动时需要ntp服务进行时间同步,在kudu启动前需要在三台服务器上安装ntp服务进行时间同步

[root@hadoop01 ~]# yum -y install ntp #安装ntp服务

[root@hadoop01 ~]# service ntpd start #启动ntp服务

[root@hadoop01 ~]# chkconfig ntpd on #设置开机启动

   

[root@hadoop02 ~]# yum -y install ntp #安装ntp服务

[root@hadoop02 ~]# service ntpd start #启动ntp服务

[root@hadoop02 ~]# chkconfig ntpd on #设置开机启动

   

[root@hadoop03 ~]# yum -y install ntp #安装ntp服务

[root@hadoop03 ~]# service ntpd start #启动ntp服务

[root@hadoop03 ~]# chkconfig ntpd on #设置开机启动

   

启动kudu集群

[root@hadoop01 ~]# service kudu-master start

[root@hadoop01 ~]# service kudu-tserver start

   

[root@hadoop02 ~]# service kudu-master start

[root@hadoop02 ~]# service kudu-tserver start

   

[root@hadoop03 ~]# service kudu-master start

[root@hadoop03 ~]# service kudu-tserver start

  

   

启动集群后访问地址http://node01:8051/显示下图所示

   

kudu安装部署_第2张图片

   

关闭kudu集群

[root@hadoop01 ~]# service kudu-master stop

[root@hadoop01 ~]# service kudu-tserver stop

   

[root@hadoop02 ~]# service kudu-master stop

[root@hadoop02 ~]# service kudu-tserver stop

   

[root@hadoop03 ~]# service kudu-master stop

[root@hadoop03 ~]# service kudu-tserver stop

   

   

部署常见问题

启动kudu的时候报错

Failed to start Kudu Master Server. Return value: 1 [FAILED]

去日志文件中查看:

错误:F0810 09:04:08.354552 4866 master_main.cc:68] Check failed: _s.ok() Bad status:Service unavailable: Cannot initialize clock: Error reading clock. Clock considered

Unsynchronized

   

解决:

第一步:首先检查是否有安装ntp:如果没有安装则使用以下命令安装:

yum -y install ntp

第二步:设置随机启动:

service ntpd start

chkconfig ntpd on

   

启动过程中报错

F0810 21:31:12.620932 20143 master_main.cc:71] Check failed: _s.ok() Bad status:

Invalid argument: Unable to initialize catalog manager: Failed to initialize sys tables

async: on-disk master list

解决:

(1):停掉master和tserver

(2):删除掉之前所有的/export/servers/kudu/master/*和/export/servers/kudu/tserver/*

   

启动过程中报错

   

F0913 15:12:00.628237 20859 master_main.cc:74] Check failed: _s.ok() Bad status: IO

error: Could not create new FS layout: unable to create file system roots: unable to

write instance metadata: Call to mkstemp() failed on name template

/export/servers/kudu/master/instance.kudutmp.XXXXXX: Permission denied (error 13)

   

这是因为kudu默认使用kudu权限进行执行,可能遇到文件夹的权限不一致情况,更改文件夹权限即可
