Objectives:
I used cloudera Manager server to install and manage hadoop clusters. I heard that general enterprises use cloudera to install and manage hadoop. I also want to try it. I checked the data for a day and found that cloudera is very mature, in addition, the installation methods of pseudo do distributed and cloudera manager are available. The author uses the manager Method for installation.
Environment:
- Host a ubuntu12.04 64-bit user name qiuchenl host name qiuchenl1 installed with SSH
- Host B ubuntu12.04 64-bit user name qiuchenl host name qiuchenl2 installed with SSH
Installation steps:
- First download the cloudera Manager Server Installation File, is a binfile will automatically download the installation (: https://ccp.cloudera.com/display/SUPPORT/Cloudera+Manager+Free+Edition+Download) I downloaded a latest version of the download file name: cloudera-manager-installer.bin
Start installing the software and run the following command: (official guide: https://ccp.cloudera.com/display/express37/Automated+Installation+of+CDH+by+Cloudera+Manager)
- Chmod U + x cloudra-manager-installer.bin
- Sudo./cloudra-manager-installer.bin
- Now go to the installation interface, basically all the way to next, which should be noted in the following aspects:
- The installation may be due to the speed of the network. There will be no sound on the interface. You only need to wait patiently. Do not force the installation program to be closed. If it is forced to close, the installation will fail again, you can only reinstall the system.
- After the installation is complete, you will be prompted to open http: // localhost: 7180 in the browser to install the hadoop cluster.
- You can leave this field in front of the hadoop cluster installation interface. On the following interface, you need to select root or user name, ssh Public Key key logon, And Password Logon, I chose the root user and password login (note that the root password of all your hosts must be the same, note that the root password is not your user password) the rest is a long wait. hadoop, hbase, and hive will be installed in sequence.
