免密码配置

三台服务器同时做：
[root@localhost ~]# ssh-keygen -t rsa
一路回车
查看是否生成了秘钥：
[root@localhost ~]# ls /root/.ssh/

[root@localhost ~]# cd /root

[root@localhost ~]# ssh-copy-id -i .ssh/id_rsa.pub -p22 root@192.168.2.109
[root@localhost ~]# ssh-copy-id -i .ssh/id_rsa.pub -p22 root@192.168.2.110
测试：

[root@localhost ~]# ssh root@192.168.2.110

OK 可以免密登陆了

安装spark,集群配置

tar -zxvf spark-2.1.1-bin-hadoop2.7.tgz -C ../bigdata/
cd /home/bigdata/spark-2.1.1-bin-hadoop2.7

bin/spark-submit --class org.apache.spark.examples.SparkPi --master local[2] ./examples/jars/spark-examples_2.11-2.1.1.jar 10
集群配置：
mv slaves.template slaves
mv spark-env.sh.template spark-env.sh

vim slaves
添加
192.168.2.109
192.168.2.110
192.168.2.111

vim spark-env.sh
SPARK_MASTER_HOST=192.168.2.109
SPARK_MASTER_PORT=7077

启动：
/home/bigdata/spark-2.1.1-bin-hadoop2.7/sbin/start-all.sh

集群模式下运行：
[root@localhost spark-2.1.1-bin-hadoop2.7]# bin/spark-submit --class org.apache.spark.examples.SparkPi --master spark://192.168.2.109:7077 ./examples/jars/spark-examples_2.11-2.1.1.jar 10

kinbana 安装

下载路径：
https://www.elastic.co/cn/downloads/past-releases#kibana
注意选择适合自己 es的版本
解压：
[root@localhost soft]# tar -zxvf kibana-6.8.8-linux-x86_64.tar.gz -C ../bigdata/
修改配置：
server.port: 5601
server.host: "192.168.2.109"
elasticsearch.hosts: ["http://192.168.2.109:9200"]

启动：
nohup /home/bigdata/kibana-6.8.8-linux-x86_64/bin/kibana &

查看：
http://192.168.2.110:5601/app/kibana#/home?_g=()

docker 安装MySQL

docker pull mysql:5.7 # 拉取 mysql 5.7

docker run -p 3306:3306 --name mysql
-v /home/docker-v/mysql/conf:/etc/mysql
-v /home/docker-v/mysql/logs:/var/log/mysql
-v /home/docker-v/mysql/data:/var/lib/mysql
-e MYSQL_ROOT_PASSWORD=123456
-d mysql:5.7

–name：容器名，此处命名为mysql
-e：配置信息，此处配置mysql的root用户的登陆密码
-p：端口映射，此处映射 主机3306端口 到 容器的3306端口
-d：后台运行容器，保证在退出终端后容器继续运行
