scp id_rsa id_rsa.pub bigdata-4.mid.neu.com:/root/.ssh/

9、安装mysql并配置驱动：（master服务器）

卸载centos7原先自带的mariadb
rpm -qa|grep mariadb

rpm -e —nodeps mariadb-libs
rpm -e —nodeps mariadb-devel
rpm -e —nodeps mariadb-server
rpm -e —nodeps mariadb

按照顺序执行如下命令：
rpm -ivh mysql-community-common-5.7.17-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.17-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm

启动mysql：
systemctl start mysqld.service
systemctl enable mysqld

查找初始密码：
grep ‘temporary password’ /var/log/mysqld.log

登陆mysql：
mysql -uroot -pRoot,123

修改初始密码，并允许其他服务器登陆：
create database ambari;
create database hive;
create database oozie;

set global validate_password_policy=0;
set global validate_password_length=1;
set password = password(‘root123’);
update mysql.user set host=”%” where Host=’localhost’ and user = “root”;
flush privileges;

配置驱动：
mkdir /usr/share/java
mv mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar
chmod +x /usr/share/java/mysql-connector-java.jar

10、安装jdk：（master服务器）
解压缩：
tar -xvf jdk-8u211-linux-x64.tar -C /opt

export JAVA_HOME=/opt/jdk1.8.0_211
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
生效：
source /etc/profile
验证：
java -version
复制到其他节点：
scp -r /opt/jdk1.8.0_211/ bd2:/opt
scp -r /opt/jdk1.8.0_211/ bd3:/opt
scp -r /opt/jdk1.8.0_211/ bd4:/opt
其他节点设置环境变量：
vim /etc/profile
添加如下内容：
export JAVA_HOME=/opt/jdk1.8.0_211
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
生效：
source /etc/profile
验证：
java -version

11、配置本地yum源：（master服务器）

注意：需要操作系统光盘软件安装源，请自行准备，并复制到/var/www/html/目录下，如centos

启动httpd：
systemctl start httpd

解压缩：
tar -xvf ambari-2.7.3.0-centos7.tar -C /var/www/html/
tar -xvf HDP-3.1.0.0-centos7-rpm.tar -C /var/www/html/
tar -xvf HDP-UTILS-1.1.0.22-centos7.tar -C /var/www/html/
tar -xvf HDP-GPL-3.1.0.0-centos7-gpl.tar -C /var/www/html/

验证：
http://10.10.195.53/ambari/

配置yum：
vim /etc/yum.repos.d/ambari.repo
填写：
[ambari-repo]
name=ambari_repo
baseurl=http://bigdata-1.mid.neu.com/ambari/centos7/2.7.3.0-139/
enable=true
gpgcheck=false

vim /etc/yum.repos.d/hdp.repo

[hdp-repo]
name=hdp_repo
baseurl=http://bigdata-1.mid.neu.com/HDP/centos7/3.1.0.0-78/
enable=true
gpgcheck=false

vim /etc/yum.repos.d/hdp-utils.repo

[hdp-utils-repo]
name=hdp-utils_repo
baseurl=http://bigdata-1.mid.neu.com/HDP-UTILS/centos7/1.1.0.22/
enable=true
gpgcheck=false

vim /etc/yum.repos.d/hdp-gpl.repo

[hdp-gpl-repo]
name=hdp-gpl_repo
baseurl=http://bigdata-1.mid.neu.com/HDP-GPL/centos7/3.1.0.0-78/
enable=true
gpgcheck=false

[centos-repo]
name=centos_repo
baseurl=http://bigdata-1.mid.neu.com/centos/
enable=true
gpgcheck=false

移走旧文件：
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/CentOS-* /etc/yum.repos.d/bak

验证：
yum repolist

scp /etc/yum.repos.d/ambari.repo bd2:/etc/yum.repos.d
scp /etc/yum.repos.d/ambari.repo bd3:/etc/yum.repos.d
scp /etc/yum.repos.d/ambari.repo bd4:/etc/yum.repos.d

scp /etc/yum.repos.d/hdp.repo bd2:/etc/yum.repos.d
scp /etc/yum.repos.d/hdp.repo bd3:/etc/yum.repos.d
scp /etc/yum.repos.d/hdp*.repo bd4:/etc/yum.repos.d

scp /etc/yum.repos.d/centos.repo bd2:/etc/yum.repos.d
scp /etc/yum.repos.d/centos.repo bd3:/etc/yum.repos.d
scp /etc/yum.repos.d/centos.repo bd4:/etc/yum.repos.d

11—-安装libtirpc-devel

启动：
ambari-server start

访问http://10.10.195.53:8080 用户名密码：admin/admin 开始配置

详见文件：/root/.ssh/id_rsa

ambari-server setup —jdbc-db=mysql —jdbc-driver=/usr/share/java/mysql-connector-java.jar

常见问题：

原因：YARN Registry DNS的默认端口53本其它进程占用了。
方案一：
1.查询占用53端口的进程/服务
lsof -i:53
查询到PID和User，这里的User一般是systemd-resolved
2.停止占用53端口的进程/服务
systemctl stop systemd-resolved
3.在Ambari界面启动YARN Registry DNS，成功。
方案二：
直接在Ambari界面，YARN -> configs -> advanced -> RegistryDNS Bind Port，修改端口后保存。

问题：

解决：
检查mysql字符集：
show variables like “character_set_database”;
是否是latin1，如果是，则更新为utf8。
alter database druid character set utf8 collate utf8_general_ci;
重启Druid coordinator。
