一、MySQL安装配置

1、下载MySQL

mkdir -p /DATA/disk1/software/mysql/
cd /DATA/disk1/software/mysql/

[root@cdh-cm-v01 scripts]# mkdir -p /DATA/disk1/software/mysql/

下载MySQL地址：https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

2、解压缩

tar -xvf mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

[root@cdh-cm-v01 mysql]# tar -xvf mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

在这里插入图片描述

3、删除系统自带包

rpm -qa |grep mariadb-libs|awk ‘{print $1}’|xargs rpm -e --nodeps

[root@cdh-cm-v01 mysql]# rpm -qa |grep mariadb-libs|awk '{print $1}'|xargs rpm -e --nodeps

4、yum安装依赖包

yum -y install perl*;
yum -y install net-tools;
yum -y install libaio*;

[root@cdh-cm-v01 mysql]# yum -y install perl*  
[root@cdh-cm-v01 mysql]# yum -y install net-tools
[root@cdh-cm-v01 mysql]# yum -y install libaio*

在这里插入图片描述

5、安装MySQL rpm包

rpm -ivh mysql-community-common-5.7.30-1.el7.x86_64.rpm;
rpm -ivh mysql-community-libs-5.7.30-1.el7.x86_64.rpm;
rpm -ivh mysql-community-libs-compat-5.7.30-1.el7.x86_64.rpm;
rpm -ivh mysql-community-client-5.7.30-1.el7.x86_64.rpm;
rpm -ivh mysql-community-server-5.7.30-1.el7.x86_64.rpm;

[root@cdh-cm-v01 mysql]# rpm -ivh mysql-community-common-5.7.30-1.el7.x86_64.rpm;
[root@cdh-cm-v01 mysql]# rpm -ivh mysql-community-libs-5.7.30-1.el7.x86_64.rpm;
[root@cdh-cm-v01 mysql]# rpm -ivh mysql-community-libs-compat-5.7.30-1.el7.x86_64.rpm;
[root@cdh-cm-v01 mysql]# rpm -ivh mysql-community-client-5.7.30-1.el7.x86_64.rpm;
[root@cdh-cm-v01 mysql]# rpm -ivh mysql-community-server-5.7.30-1.el7.x86_64.rpm;

在这里插入图片描述

6、启动MySQL服务

systemctl start mysqld;
systemctl status mysqld;
systemctl enable mysqld;

[root@cdh-cm-v01 mysql]# systemctl start mysqld 
[root@cdh-cm-v01 mysql]# systemctl status mysqld
[root@cdh-cm-v01 mysql]# systemctl enable mysqld

在这里插入图片描述

7、MySQL5.7有默认初始密码

cat /var/log/mysqld.log | grep ‘password’

[root@cdh-cm-v01 mysql]# cat /var/log/mysqld.log | grep 'password'

2022-09-21T02:52:47.924007Z 1 [Note] A temporary password is generated for root@localhost: =f/W!YB:h0iq

在这里插入图片描述

8、登录MySQL修改密码

mysql -uroot -p
=f/W!YB:h0iq

[root@cdh-cm-v01 mysql]# mysql -uroot -p
Enter password: =f/W!YB:h0iq
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'rootROOT@1234';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

在这里插入图片描述

9、配置MySQL驱动

1）安装MySQL驱动环境

yum -y install mysql-connector-java.noarch

  • 注意

默认版本导致安装hive的时候出现问题
有 hive 服务的机器需安装 mysql jdbc 驱动

[root@cdh-cm-v01 mysql]# yum -y install mysql-connector-java.noarch

在这里插入图片描述

2）备份MySQL新驱动包

cd /usr/share/java/;
mv mysql-connector-java.jar mysql-connector-java.jar.bak;

[root@cdh-cm-v01 mysql]# cd /usr/share/java/
[root@cdh-cm-v01 java]# mv mysql-connector-java.jar mysql-connector-java.jar.bak

在这里插入图片描述

3）替换mysq-connector版本

下载地址：wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.47/mysql-connector-java-5.1.47.jar

ln -s ./mysql-connector-java-5.1.47.jar ./mysql-connector-java.jar

[root@cdh-cm-v01 java]# wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.47/mysql-connector-java-5.1.47.jar
[root@cdh-cm-v01 java]# ln -s ./mysql-connector-java-5.1.47.jar ./mysql-connector-java.jar

在这里插入图片描述

4）检测软连接

ls -l /usr/share/java/|grep mysql-conn

[root@cdh-cm-v01 java]# ls -l /usr/share/java/|grep mysql-conn

在这里插入图片描述

二、创建CDH数据库

1、登录MySQL

mysql -uroot -prootROOT@1234

[root@cdh-cm-v01 java]# mysql -uroot -prootROOT@1234

在这里插入图片描述

2、创建CDH所需数据库

%严格控制到IP段或者具体IP地址，密码区别开

grant all on scm.* to ‘scm’@‘192.168.0.128’ identified by ‘rootROOT@1234’;

grant all on oozie.* to ‘oozie’@‘192.168.0.128’ identified by ‘rootROOT@1234’;
flush privileges;

3、设置CDH数据库

1）Cloudera Manager Server与MySQL同服务器

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

[root@cdh-cm-v01 lib]# /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

[root@cdh-cm-v01 lib]# /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm
Enter SCM password: rootROOT@1234

Wed Sep 21 22:16:01 CST 2022 WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

[root@cdh-cm-v01 lib]# /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

2）Cloudera Manager Server与MySQL不同服务器

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h --scm-host scm scm

[root@cdh-cm-v01 lib]# /opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h <mysql-host-ip> --scm-host <cm-server-ip> scm scm
