拉取cdh的docker镜像， 运行容器

1， cloudera-manager启动脚本分析

/home/cloudera/cloudera-manager：

# cm server启动log 'Starting Cloudera Manager server...'service cloudera-scm-server start 2>&1 > /dev/null# cm agent启动log 'Starting Cloudera Manager agent...'service cloudera-scm-agent start 2>&1 > /dev/null

2， 进入容器： 启动cdh服务

###, 运行容器, 启动clouderaroot@wang-pc:/var/lib/docker# docker exec -it mycdh3 bash[root@quickstart /]# lsbin  boot  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  packer-files  proc  root  sbin  selinux  srv  sys  tmp  usr  var[root@quickstart /]# /home/cloudera/cloudera-manager --enterprise[QuickStart] Shutting down CDH services via init scripts...kafka-server: unrecognized serviceJMX enabled by defaultUsing config: /etc/zookeeper/conf/zoo.cfg[QuickStart] Disabling CDH services on boot...error reading information on service kafka-server: No such file or directory[QuickStart] Starting Cloudera Manager server...[QuickStart] Waiting for Cloudera Manager API...[QuickStart] Starting Cloudera Manager agent...[QuickStart] Activating trial license for Enterprise...[QuickStart] Configuring deployment...Submitted jobs: 16[QuickStart] Deploying client configuration...Submitted jobs: 17[QuickStart] Starting Cloudera Management Service...Submitted jobs: 25[QuickStart] Enabling Cloudera Manager daemons on boot...________________________________________________________________________________Success!

配置host映射
