1. 安装kudu主程序

1.1 安装kudu

上传依赖 cloudera-kudu.repo 文件保存到 /etc/yum.repos.d/
在主机执行命令sudo yum install kudu 以及sudo yum install kudu-master
在从机执行命令sudo yum install kudu 以及sudo yum install kudu-tserver

1.2 配置kudu

注：配置后如有启动问题，可查看日志/var/log/kudu/kudu-master.FATAL

1.2.1 集群域名

192.168.33.2 win
192.168.33.101 node1
192.168.33.102 node2
192.168.33.103 node3
192.168.33.104 node4

1.2.2 配置marster

主要配置信息主要在一下路径：

/etc/kudu/conf.dist/master.gflagfile
/etc/default/kudu-master
/etc/kudu/conf.dist/tserver.gflagfile
/etc/default/kudu-tserver

1.2.2.1 配置`master.gflagfile`(不需要调整)

# 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=/var/lib/kudu/master
--fs_data_dirs=/var/lib/kudu/master

1.2.2.2配置文件`kudu-master` :

export FLAGS_log_dir=/var/log/kudu
export FLAGS_rpc_bind_addresses=node1:7051

1.2.3 配置tserver

1.2.3.1 配置`tserver.gflagfile`

#/etc/kudu/conf.dist/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=/var/lib/kudu/tserver
--fs_data_dirs=/var/lib/kudu/tserver
--tserver_master_addrs=node1:7051

1.2.3.2 配置`kudu-tserver` :

export FLAGS_log_dir=/var/log/kudu
export FLAGS_rpc_bind_addresses=node2:7050

2 启动服务

2.1 启动Marster

sudo service kudu-master start

注：配置后如有启动问题，可查看日志/var/log/kudu/kudu-master.FATAL

如果启动失败，需要先设置好时间 date -s '2018/08/13 00:36:00',

再执行/etc/init.d/ntpd restart, 然后再次启动。

2.2 启动Tablet Server

sudo service kudu-tserver start

同启动master注意事项：

hosts配置好集群域名+地址

设置好时间及NTP服务

结合启动失败日志

如果出现以下异常，可参考链接解决方式：
Bad status: Not found: Unable to initialize catalog manager: Failed to initialize sys tables async: Could not load tablet metadata from /var/lib/kudu/master/tablet-meta/00000000000000000000000000000000: /var/lib/kudu/master/tablet-meta/00000000000000000000000000000000: No such file or directory (error 2)
