CentOS7安装spark2.0集群

时间:2022-12-22 13:26:45

1、虚拟机运行环境: 

            JDK: jdk1.8.0_171 64位 
            Scala:scala-2.12.6
            Spark:spark-2.3.1-bin-hadoop2.7

2、集群网络环境:

    使用winscp工具上传jdk、scala、spark安装包到master主机/opt下新建的对应文件夹下

1)安装jdk

解压安装包到目录/usr/local下

[root@master conf]# tar -xvf jdk-8u171-linux-x64.tar.gz    -C /usr/local/

修改配置文件:

[root@master conf]# vi /etc/profile
#jdk
export JAVA_HOME=/usr/local/jdk1.8.0_171
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
jdk1.8.0_171/ 

2)安装scala

解压scala安装包到目录/usr/local下

[root@master conf]# tar -xvf scala-2.12.6\ .tgz    -C /usr/local/

修改配置文件:

[root@master conf]# vi /etc/profile
#scala
export SCALA_HOME=/usr/local/scala-2.12.6
export PATH=$PATH:$SCALA_HOME/bin

3)安装spark

解压安装包/usr/local目录下

[root@master conf]# tar -xvf /opt/spark/spark-2.3.1-bin-hadoop2.7.tgz  -C /usr/local

修改配置文件:

[root@master conf]# vi /etc/profile
#spark
export SPARK_HOME=/opt/spark/spark-2.3.1-bin-hadoop2.7
export PATH=$PATH:$SPARK_HOME/bin
export SPARK_EXAMPLES_JAR=$SPARK_HOME/examples/jars/spark-examples_3.11-2.3.1.jar

配置spark:

01.修改spark-env.sh如下:

CentOS7安装spark2.0集群

[root@master conf]# cp spark-env.sh.template  spark-env.sh      复制spark-env.sh.template模板到spark-env.sh,

[root@master conf]# vim spark-env.sh         打开文件,在最下方添加如下配置:

SPARK_MASTER_IP=192.168.52.128

export JAVA_HOME=/usr/local/jdk1.8.0_171

export SCALA_HOME=/usr/local/scala-2.12.6

02. 修改配置文件slaves

[root@master conf]# cp slaves.template   slaves
[root@master conf]# vim slaves

CentOS7安装spark2.0集群

03.将文件从master复制到sd1和sd2:

[root@master conf]# scp -r /usr/local/spark-2.3.1-bin-hadoop2.7/conf root@sd1:/usr/local/spark-2.3.1-bin-hadoop2.7/
[root@master conf]# scp -r /usr/local/spark-2.3.1-bin-hadoop2.7/conf root@sd2:/usr/local/spark-2.3.1-bin-hadoop2.7/

 复制目录:
  (1)将本地目录拷贝到远程
  scp -r 目录名用户名@计算机IP或者计算机名称:远程路径
  (2)从远程将目录拷回本地

  scp -r 用户名@计算机IP或者计算机名称:目录名本地路径

[root@master conf]# scp -r /usr/local/spark-2.3.1-bin-hadoop2.7/conf root@sd1:/usr/local/spark-2.3.1-bin-hadoop2.7/
spark-defaults.conf.template                                                                              100% 1292     1.3KB/s   00:00

metrics.properties.template                                                                               100% 7801     7.6KB/s   00:00

.slaves.swp 

3、SSH免密码验证登陆:

1)修改主机名称

[root@master ~]# vim /etc/hostname

CentOS7安装spark2.0集群

[root@master ~]# vim /etc/hosts

CentOS7安装spark2.0集群

2)生成秘钥,执行命令ssh-keygen -t rsa,然后一直按回车键即可

CentOS7安装spark2.0集群

[root@server ~]# ssh-keygen -b 1024 -t rsa
Generating public/private rsa key pair.     #提示正在生成rsa密钥对
Enter file in which to save the key (/home/usrname/.ssh/id_dsa):     #询问公钥和私钥存放的位置,回车用默认位置即可
Enter passphrase (empty for no passphrase):     #询问输入私钥密语,输入密语
Enter same passphrase again:     #再次提示输入密语确认
Your identification has been saved in /home/usrname/.ssh/id_dsa.     #提示公钥和私钥已经存放在/root/.ssh/目录下
Your public key has been saved in /home/usrname/.ssh/id_dsa.pub.

3)复制spark-master结点的id_rsa.pub文件到另外两个结点:
sup -r  id_rsa.pub root@sd1:~/.ssh/
sup -r  id_rsa.pub root@sd2:~/.ssh/

4.Centos7 防火墙关闭 :
#查看防火墙的状态 
firewall-cmd --state
#关闭防火墙
systemctl stop firewalld.service
#禁止firewall开机启动
systemctl disable firewalld.service
如果防火墙没有关闭,sd1,sd2连接master中端口将被屏蔽掉,虽然网络可以PING通。但在启动Hadoop ,Spark 时Work 将连接不上Master
