以cm節(jié)點(172.31.13.38)為例:
hostname配置
/etc/hostname文件如下:
ip-172-31-13-38.ap-southeast-1.compute.internal
或者你可以通過命令修改立即生效
[root@ip-172-31-13-38 ~]$ hostnamectl set-hostname ip-172-31-13-38.ap-southeast-1.compute.internal
<font face="微軟雅黑" size=4 color=red >注意:這里修改hostname跟REDHAT6的區(qū)別
hosts配置
/etc/hosts文件如下:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.31.13.38 ip-172-31-13-38.ap-southeast-1.compute.internal 172.31.11.232 ip-172-31-11-232.ap-southeast-1.compute.internal 172.31.11.9 ip-172-31-11-9.ap-southeast-1.compute.internal 172.31.13.166 ip-172-31-13-166.ap-southeast-1.compute.internal
以上兩步操作,在集群中其它節(jié)點做相應配置。確認需要安裝的4臺主機的hosts文件:
在所有節(jié)點執(zhí)行setenforce 0 命令,此處使用批處理shell執(zhí)行:
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "setenforce 0"
集群所有節(jié)點修改/etc/selinux/config文件如下:
SELINUX=disabled SELINUXTYPE=targeted
檢查所有機器是否已修改成功:
sh ssh_do_all.sh node.list "cat /etc/selinux/config | grep SELINUX"
集群所有節(jié)點執(zhí)行systemctl stop firewalld命令,此處通過shell批量執(zhí)行命令如下:
[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl stop firewalld" [root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl disable firewalld" [root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "systemctl status firewalld"
在Redhat7.x的操作系統(tǒng)上,已經默認的安裝了chrony,我們這里先卸載chrony,然后安裝ntp。使用ntp來配置各臺機器的時鐘同步,將cm(172.31.13.38)服務作為本地ntp服務器,其它3臺服務器與其保持同步。
1.所有機器卸載chrony
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"
2.所有機器安裝ntp
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y install ntp"
3.cm機器配置時鐘與自己同步
[root@ip-172-31-16-68 shell]# vim /etc/ntp.conf #server 0.rhel.pool.ntp.org iburst #server 1.rhel.pool.ntp.org iburst #server 2.rhel.pool.ntp.org iburst #server 3.rhel.pool.ntp.org iburst server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10
4.集群其它節(jié)點,配置找cm機器去同步
#server 0.rhel.pool.ntp.org iburst #server 1.rhel.pool.ntp.org iburst #server 2.rhel.pool.ntp.org iburst #server 3.rhel.pool.ntp.org iburst server 172.31.13.38
5.重啟所有機器的ntp服務
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl restart ntpd" [root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl status ntpd" [root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "systemctl enable ntpd"
6.驗證始終同步,在所有節(jié)點執(zhí)行ntpq -p命令,如下使用腳本批量執(zhí)行
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "ntpq -p"
左邊出現*號表示同步成功。
所有節(jié)點執(zhí)行
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo vm.swappiness = 10 >> /etc/sysctl.conf" [root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "sysctl vm.swappiness=10"
所有節(jié)點執(zhí)行:
[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo never > /sys/kernel/mm/transparent_hugepage/defrag " [root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "echo never > /sys/kernel/mm/transparent_hugepage/enabled"
設置開機自關閉
將如下腳本添加到/etc/rc.d/rc.local文件中
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabled fi if test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defrag fi
同步到所有節(jié)點
<font face="微軟雅黑" size=4 color=red >Fayson用的是AWS的環(huán)境,這步是可以省略的,放在這里供物理機部署的兄弟們參考。
掛載操作系統(tǒng)iso文件
[root@ip-172-31-2-159 ~]$ sudo mkdir /media/DVD1 [root@ip-172-31-2-159 ~]$ sudo mount -o loop CentOS-7-x86_64-DVD-1611.iso /media/DVD1/
配置操作系統(tǒng)repo
[root@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/local_os.repo [local_iso] name=CentOS-$releasever - Media baseurl=file:///media/DVD1 gpgcheck=0 enabled=1 [root@ip-172-31-2-159 ~]$ sudo yum repolist
安裝httpd服務
[root@ip-172-31-2-159 ~]$ yum -y install httpd
啟動或停止httpd服務
[root@ip-172-31-2-159 ~]$ systemctl start httpd [root@ip-172-31-2-159 ~]$ systemctl stop httpd
安裝完httpd后,重新制作操作系統(tǒng)repo,換成http的方式方便其它服務器也可以訪問
[root@ip-172-31-2-159 ~]$ sudo mkdir /var/www/html/iso [root@ip-172-31-2-159 ~]$ sudo scp -r /media/DVD1/* /var/www/html/iso/ [root@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/os.repo [osrepo] name=os_repo baseurl=http://172.31.2.159/iso/ enabled=true gpgcheck=false [root@ip-172-31-2-159 ~]$ sudo yum repolist
1.安裝MariaDB
[root@ip-172-31-13-38 ~]# yum -y install mariadb [root@ip-172-31-13-38 ~]# yum -y install mariadb-server
2.啟動并配置MariaDB
[root@ip-172-31-13-38 ~]# systemctl start mariadb [root@ip-172-31-13-38 ~]# systemctl enable mariadb [root@ip-172-31-13-38 ~]# /usr/bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] n ... skipping. By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
3.建立CM,Hive等需要的表
[root@ip-172-31-13-38 ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.

1.通過CM安裝Kudu1.7
添加Kudu服務
2.選擇Master和Tablet Server
3.配置相應的目錄,注:無論是Master還是Tablet根據實際情況數據目錄(fs_data_dir)應該都可能有多個,以提高并發(fā)讀寫,從而提高Kudu性能。
4.啟動Kudu服務
5.安裝完畢
6.配置Impala
回到主頁重啟Impala和Hue
至此,CDH5.16.1+Kudu1.7安裝完畢。
