-系统初始化(每个服务器都要做）
-# 关闭iptables、禁用selinux
-sudo systemctl disable firewalld
-sudo systemctl stop firewalld
-sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config && setenforce 0
-# 每台服务器之间设置免密认证
-# CM
-cat >> /etc/hosts <<EOF
-.168.88.40 cdh.master master
-.168.88.41 cdh.node1 node1
-.168.88.42 cdh.node2 node2
-#192.168.1.150 cdh.node3.aniu.so node3
-EOF
-## 注：在每台服务器配置hosts，master和node1/2/3代表服务器的主机名
-sudo hostnamectl set-hostname "master"
-ssh免密码登录配置（每一台）
-. 在master 生成key 并自己配置自己的pub key
-ssh-keygen -t dsa
-ssh-copy-id -i ~/.ssh/id_dsa.pub 192.168.88.40 #这里是master ip  40
-. 主服务器与其它服务器免密码，在主节点上以下命令发送到其他对应服务器：
-rsync -avz  .ssh/  192.168.88.41:~/
-# 设置swap参数
-echo never > /sys/kernel/mm/transparent_hugepage/defrag  #建议写到开启启动新里
-sysctl -w vm.swappiness=0  # 建议写进sysctl.conf
-cat >>/etc/sysct <<EOF
-vm.swappiness=0
-EOF
-sysctl -p
-# 设置ntp同步服务器时间
-yum install ntp -y
-Edit the /etc/ntp.conf file to add NTP servers, as in the following example.
-server 0.cn.pool.ntp.org
-server 1.pool.ntp.org
-server 2.pool.ntp.org
-sudo systemctl start ntpd
-sudo systemctl enable ntpd
-#for centos6
-*/2 * * * * /usr/sbin/ntpdate 0.cn.pool.ntp.org >> /dev/null 2>&1

-Cloudera安装步骤
-参考：https://www.cloudera.com/documentation/enterprise/latest/topics/installation_installation.html
-阶段1：安装JDK（忽略）
-[Java SE 8 Downloads](http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html)
-export JAVA_HOME=/usr/java/jdk.1.8.0_nn
-# java -version
-java version "1.8.0_144"
-Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
-Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
-# 注 此处不用安装JDK，因为CM源有封装好的jdk，
-阶段2：设置数据库
-scp ~/rpm/rpmbuild2019/mysql20190506/RPMS/x86_64/ops_mysql-5.7.18-1.0.x86_64.rpm  root@192.168.88.40:~
-# 使用mysql数据库，提前安装好mysql
-# mysql -u root -ppassword -e "create database cmf DEFAULT CHARACTER SET utf8;"
-# mysql -u root -ppassword -e "GRANT ALL PRIVILEGES ON `cmf`.* TO 'cmf'@'localhost' IDENTIFIED BY '224088' ";"
-阶段3：安装Cloudera Manager服务器
-dns client 改为 8.8.4.4
-# 配置cloudera-cdh源和cloudera-manager源
-# cloudera-manager
-cd /etc/yum.repos.d/
-wget http://archive.cloudera.com/cm5/redhat/7/x86_64/cm/cloudera-manager.repo
-# cloudera-cdh
-wget https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/cloudera-cdh5.repo
-# 安装jdk和cloudera-manager
-sudo yum install oracle-j2sdk1.7 -y
-sudo yum install cloudera-manager-daemons cloudera-manager-server -y
-sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
-axel https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5/RPMS/x86_64/oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm
-axel  https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5/RPMS/x86_64/cloudera-manager-daemons-5.16.2-1.cm5162.p0.7.el7.x86_64.rpm
-aria2c  or 迅雷

-阶段4：启动CM服务并通过浏览器访问
-systemctl start cloudera-scm-server
-#有问题
-tailf /var/log/cloudera-scm-server/cloudera-scm-server.log
-</pre>
-=troubleshooting=
-<pre>
-安装这个就行了
-mysql-connector-java
-安装MySQL JDBC Driver
-wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
-tar zxvf mysql-connector-java-5.1.46.tar.gz  && mkdir -p /usr/share/java/
-cd mysql-connector-java-5.1.46 && cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
-下载 mysql-connector-java-8.0.11-1.el7.noarch.rpm
-https://dev.mysql.com/downloads/connector/j/
