1.因为我们安装cdh6.3.2。cdh支持的是5.6和5.7版本的mysql。
2. 步骤
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-server_5.7.36-1ubuntu18.04_amd64.deb-bundle.tar
tar xvf ./mysql-server_5.7.36-1ubuntu18.04_amd64.deb-bundle.tar
sudo apt-get install ./libmysql*
sudo apt-get install libtinfo5
sudo apt-get install ./mysql-community-client_5.7.36-1ubuntu18.04_amd64.deb
sudo apt-get install ./mysql-client_5.7.36-1ubuntu18.04_amd64.deb
sudo apt-get install ./mysql-community-server_5.7.36-1ubuntu18.04_amd64.deb
sudo apt-get install ./mysql-server_5.7.36-1ubuntu18.04_amd64.deb
- 检查mysql状态
systemctl status mysql.service
三：初始化数据库配置
- 输入命令
sudo mysql_secure_installation
- 这里是进行密码的校验，输入n
-
删除匿名用户，输入n
-
是否不允许root远程登陆，输入n，允许远程
-
是否删除test数据库，选择不删除，输入n
-
是否立即生效权限，选择是，输入y
到这里配置完成
- 检查数据库状态
systemctl status mysql.service
四. 修改密码，权限
-- 修改root用户密码
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
-- 给root授权允许任意地址访问
CREATE USER 'root'@'%' IDENTIFIED BY '123456';
ALTER USER 'root'@'%' IDENTIFIED BY '123456';
-- 给root用户所有权限
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
flush privileges;
vim /etc/mysql/mysql.conf.d/mysqld.cnf
systemctl restart mysql.service
五. dbeaver进行测试
