kudu安装部署

安装部署节点规划

节点	kudu-master	kudu-tserver
node01	是	是
node02	是	是
node03	是	是

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上

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上

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

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
