此篇基本与官方文档一致,细节不一样的地方会标注
我的环境:
server1 192.168.1.201 4核8 g 120 g(固态)
server2 192.168.1.202 4核8 g 120 g + 500 g(固态)
server3 192.168.1.203 4核8 g 120 g + 500 g(固态)
server4 192.168.1.204 4核8 g 120 g + 500 g(固态)
以上机型用鞋匠批量安装centos7.5最小。
修改主机文件,关闭防火墙(批量默认关闭),关闭selinux(批量默认关闭)
4台主机互相设置免密登陆
127.0.0.1 ,, localhost localhost.localdomain localhost4 localhost4.localdomain4
::1,,,,,,,,,localhost localhost.localdomain localhost6 localhost6.localdomain
192.168.1.201 server1
192.168.1.202 server2
192.168.1.203 server3
192.168.1.204 server4
批量操作可以使用ansible
0,所有节点操作,替换阿里源,epel
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/centos - 7.回购
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel - 7.回购
#百胜清洁all
#百胜makecache快
1,所有节点操作,添加Cloudera源和键
#, wget https://archive.cloudera.com/cm6/6.0.1/redhat7/yum/cloudera-manager.repo -P /etc/yum.repos.d/ #, rpm ——import https://archive.cloudera.com/cm6/6.0.0/redhat7/yum/RPM-GPG-KEY-cloudera
2, server1,配置jdk环境(此处建议遵循官方文档百胜安装,不建议手动安装,后面的Auto-TLS会有问题)
#, yum install oracle-j2sdk1.8
3, server1,安装云管理器服务器(此处建议只安装cloudera-manager-server)
#, yum install cloudera-manager-server
4, server1,使Auto_Tls(开启https的支持,此为可选操作,我在后面遇到了问题,为了排除问题,所以这一步没有做)
5, server1,安装数据库(Mariadb Mysql都可以的,根据个人喜好,此处Mysql为例)
#,wget http://repo.mysql.com/mysql -社区-释放- el7 - 5. - noarch.rpm #,rpm -ivh Mysql -社区-释放- el7 noarch——5.。rpm #,yum install mysql服务器
修改数据库的配置文件
#,。vim /etc/my . cnf中所做
