怎么在Redhat7.4安装CDH5.16.1

这篇文章主要为大家展示了"怎么在Redhat7.4安装CDH5.16.1"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"怎么在Redhat7.4安装CDH5.16.1"这篇文章吧。

前置准备

2.1.hostname及hosts配置

集群中各个节点之间能互相通信使用静态IP地址。IP地址和主机名通过/etc/hosts配置，主机名通过/etc/hostname进行配置。

以cm节点（172.31.13.38）为例：

• hostname配置

/etc/hostname文件如下：

ip-172-31-13-38.ap-southeast-1.compute.internal

或者你可以通过命令修改立即生效

[root@ip-172-31-13-38 ~]$ hostnamectl set-hostname ip-172-31-13-38.ap-southeast-1.compute.internal

注意：这里修改hostname跟REDHAT6的区别

• 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.localdomain6172.31.13.38 ip-172-31-13-38.ap-southeast-1.compute.internal172.31.11.232 ip-172-31-11-232.ap-southeast-1.compute.internal172.31.11.9 ip-172-31-11-9.ap-southeast-1.compute.internal172.31.13.166 ip-172-31-13-166.ap-southeast-1.compute.internal

以上两步操作，在集群中其它节点做相应配置。确认需要安装的4台主机的hosts文件：

2.2.禁用SELinux

在所有节点执行setenforce 0 命令，此处使用批处理shell执行：

[root@ip-172-31-13-38 ~]$ sh ssh_do_all.sh node.list "setenforce 0"

集群所有节点修改/etc/selinux/config文件如下：

SELINUX=disabledSELINUXTYPE=targeted

检查所有机器是否已修改成功：

sh ssh_do_all.sh node.list "cat /etc/selinux/config | grep SELINUX"

2.3.关闭防火墙

集群所有节点执行systemctl stop firewalld命令，此处通过shell批量执行命令如下：

[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"

2.4.集群时钟同步

在Redhat7.x的操作系统上，已经默认的安装了chrony，我们这里先卸载chrony，然后安装ntp。使用ntp来配置各台机器的时钟同步，将cm（172.31.13.38）服务作为本地ntp服务器，其它3台服务器与其保持同步。

1.所有机器卸载chrony

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"

2.所有机器安装ntp

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "yum -y install ntp"

3.cm机器配置时钟与自己同步

[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 iburstserver  127.127.1.0     # local clockfudge   127.127.1.0 stratum 10

4.集群其它节点，配置找cm机器去同步

#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 iburstserver 172.31.13.38

5.重启所有机器的ntp服务

[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.验证始终同步，在所有节点执行ntpq -p命令，如下使用脚本批量执行

[root@ip-172-31-13-38 shell]# sh ssh_do_all.sh node.list "ntpq -p"

左边出现*号表示同步成功。

2.5.设置swap

所有节点执行

[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"

2.6.设置透明大页面

所有节点执行：

[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"

设置开机自关闭

将如下脚本添加到/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

同步到所有节点

2.7.配置操作系统repo

Fayson用的是AWS的环境，这步是可以省略的，放在这里供物理机部署的兄弟们参考。

• 挂载操作系统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/

• 配置操作系统repo

[root@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/local_os.repo[local_iso]    name=CentOS-$releasever - Mediabaseurl=file:///media/DVD1gpgcheck=0enabled=1[root@ip-172-31-2-159 ~]$ sudo yum repolist

2.8.安装http服务

• 安装httpd服务

[root@ip-172-31-2-159 ~]$ yum -y install httpd

• 启动或停止httpd服务

[root@ip-172-31-2-159 ~]$ systemctl start httpd[root@ip-172-31-2-159 ~]$ systemctl stop httpd

• 安装完httpd后，重新制作操作系统repo，换成http的方式方便其它服务器也可以访问

[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_repobaseurl=http://172.31.2.159/iso/enabled=truegpgcheck=false[root@ip-172-31-2-159 ~]$ sudo yum repolist

2.9.安装MariaDB

1.安装MariaDB

[root@ip-172-31-13-38 ~]# yum -y install mariadb[root@ip-172-31-13-38 ~]# yum -y install mariadb-server

2.启动并配置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_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB      SERVERS IN PRODUCTION USE!
