2.linux基础配置

2.1创建用户

在各个节点上创建hadoop用户

[root@node-01 ~]# groupadd hadoop [root@node-01 ~]# useradd -g hadoop hadoop [root@node-01 ~]# passwd hadoop ( 密码为hadoop)

2.2赋予超管权限

在工作中一般不会让我们通过root用户来操作，因此我们给hadoop用于赋予sudo权限

[root@node-01 ~]# visudo 注释该行： # %wheel ALL=(ALL) NOPASSWD: ALL 新增： hadoop ALL=(ALL) NOPASSWD: ALL

2.3禁用防火墙

生产环境一般由专业运维人员来限制相关端口，而不是完全禁用防火墙。在学习中，通过如下命令禁用防火墙，避免多个节点之间通信受到影响:

[hadoop@node-01 ~]$ sudo systemctl disable firewalld [hadoop@node-01 ~]$ sudo systemctl stop firewalld [hadoop@node-01 ~]$ sudo systemctl status firewalld

2.4修改网络时间和区域

[root@node-01 ~]# su - hadoop [hadoop@node-01 ~]$ sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

2.5禁用SELinux

SELinux是美国国家宇航局开发的Linux的安全子系统，可以避免出现各种莫名其妙的问题。

#检查SELinux状态 [hadoop@node-01 ~]$ getenforce Enforcing #临时禁用 [hadoop@node-01 ~]$ sudo setenforce 0 #永久禁用 [hadoop@node-01 ~]$ sudo vi /etc/selinux/config #将SELINUX=enforcing改为 SELINUX=disabled

2.6umask设置

umask用于设置在Linux上创建新文件或文件夹时授予的默认权限或基本权限。大多数Linux发行版将022设置为默认umask值。 umask值022授予新文件或文件夹的755权限。 umask值027授予新文件或文件夹的750权限。

Ambari，HDP和HDF支持的umask值为022（等价于0022），027（等价于0027）。这些值必须在所有主机上设置。

#查看当前状态 [hadoop@node-01 ~]$ umask 0002 [hadoop@node-01 ~]$ sudo vi /etc/profile #新增 umask配置 umask 0022 [hadoop@node-01 ~]$ source /etc/profile [hadoop@node-01 ~]$ umask 0022

2.7文件描述符配置

[hadoop@node-01 ~]$ sudo vi /etc/security/limits.conf # 表示任何一个用户可以打开的最大的文件描述符数量 * soft nofile 655350 * hard nofile 655350

2.8SSH免密设置

[hadoop@node-01 ~]$ ssh-keygen [hadoop@node-01 ~]$ cd .ssh/ [hadoop@node-01 .ssh]$ cat id_rsa.pub >> authorized_keys [hadoop@node-01 .ssh]$ chmod 700 ../.ssh [hadoop@node-01 .ssh]$ chmod 600 ../.ssh/authorized_keys

3.安装JDK

[hadoop@node-01 ~]$ sudo tar -zxvf /data/jdk-8u231-linux-x64.tar.gz -C /usr/local/
[hadoop@node-01 ~]$ sudo ln -s /usr/local/jdk1.8.0_231/ /usr/local/jdk

[hadoop@node-01 ~]$ sudo vi /etc/profile
# jdk 1.8
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

[hadoop@node-01 ~]$ source /etc/profile
[hadoop@node-01 ~]$ java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

4.安装Apache

4.1Apache下载安装

#安装Apache [hadoop@node-01 ~]$ sudo yum -y install httpd #设置开机启动 [hadoop@node-01 ~]$ sudo systemctl enable httpd #启动服务 [hadoop@node-01 ~]$ sudo systemctl start httpd

访问 http://192.169.1.101 或者 http://node-01

4.2HDP安装包部署到Apache

#移动HDP软件包到html目录下，并解压：
[hadoop@node-01 ~]$ cd /var/www/html/
[hadoop@node-01 html]$ sudo mv /data/ambari-2.7.4.0-centos7.tar.gz ./
[hadoop@node-01 html]$ sudo mv /data/HDP-* ./

#解压安装包
[hadoop@node-01 html]$ sudo tar -zxvf ambari-2.7.4.0-centos7.tar.gz

[hadoop@node-01 html]$ sudo tar -zxvf HDP-3.1.4.0-centos7-rpm.tar.gz

[hadoop@node-01 html]$ sudo tar -zxvf HDP-GPL-3.1.4.0-centos7-gpl.tar.gz

[hadoop@node-01 html]$ sudo tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz

#更改目录权限
[hadoop@node-01 html]$ sudo chmod -R ugo+rX /var/www/html/

4.3配置本地yum源

[hadoop@node-01 yum]$ cd /etc/yum.repos.d/ [hadoop@node-01 yum.repos.d]$ sudo vi ambari.repo [ambari-repo] name=ambari baseurl=http://node-01/ambari/centos7/2.7.4.0-118/ gpgcheck=0 enabled=1

[hadoop@node-01 yum.repos.d]$ yum repolist

5.MySQL元数据库安装

5.1安装MySQL5.6版本

#安装MySQL yum仓库
[hadoop@node-01 ~]$ sudo yum -y localinstall https://dev.mysql.com/get/mysql56-community-release-el7-8.noarch.rpm

#安装MySQL
[hadoop@node-01 ~]$ sudo yum install mysql-community-server
#设置开机启动
[hadoop@node-01 ~]$ sudo systemctl enable mysqld
[hadoop@node-01 ~]$ sudo systemctl start mysqld

#设置密码
[hadoop@node-01 ~]$ sudo mysqladmin -u root password '密码'
#进入mysql数据库
[hadoop@node-01 ~]$ sudo mysql -u root -p
#配置远程连接
mysql> grant all on *.* to 'root'@'%' identified by '密码';
Query OK, 0 rows affected (0.00 sec)
#配置远程连接

mysql> create database ambari;

Query OK, 1 row affected (0.00 sec)

mysql> grant all on ambari.* to 'ambari'@'%' identified by '密码';
mysql> grant all on ambari.* to 'ambari'@'node-01' identified by '密码';
Query OK, 0 rows affected (0.00 sec)

5.2安装MySQL java驱动

[hadoop@node-01 ~]$ sudo mkdir -p /usr/share/java [hadoop@node-01 ~]$ sudo mv /data/mysql-connector-java-8.0.18.jar /usr/share/java/

6安装Ambari

6.1安装Ambari-server

[hadoop@node-01 ~]$ sudo yum -y install ambari-server
