【Linux】统信UOS服务器安装MySQL8.0（RPM）
目录
一、下载安装包
二、安装MySQL
2.1hive适配
2.2ranger适配
3.2DolphinScheduler适配
一、下载安装包
官网下载安装包：MySQL :: MySQL Downloads
选择社区版本下载
点击MySQL Community Server
选择对应系统的MySQL版本号
统信1060a 操作系统对应 redhat8 ，我们下载对应MySQL RPM包
选择直接下载
二、安装MySQL
## 解压
tar -xvf mysql-8.0.40-1.el8.x86_64.rpm-bundle.tar
## 安装
yum install -y net-tools perl libaio
rpm -ivh mysql-community-common-8.0.40-1.el8.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.0.40-1.el8.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.40-1.el8.x86_64.rpm
rpm -ivh mysql-community-client-8.0.40-1.el8.x86_64.rpm
rpm -ivh mysql-community-icu-data-files-8.0.40-1.el8.x86_64.rpm
rpm -ivh mysql-community-server-8.0.40-1.el8.x86_64.rpm
启动MySQL
systemctl start mysqld 这个是启动mysql
systemctl status mysqld 查看mysql的状态
# 查看默认密码
grep password /var/log/mysqld.log
查看密码
grep password /var/log/mysqld.log
-- 进入mysql
mysql -uroot -p 敲回车
粘贴密码即可
修改默认密码
alter user root@localhost identified by 'G1u2n3h4e5!';
4、更改密码策略等级
set global validate_password.policy=LOW; # 修改密码策略等级为LOW
set global validate_password.length=4; # 密码的最小长度
set global validate_password.mixed_case_count=0; # 设置密码中至少要包含0个大写字母和小写字母
set global validate_password.number_count=0; # 设置密码中至少要包含0个数字
set global validate_password.special_char_count=0; # 设置密码中至少要包含0个特殊字符
5、 修改更简单的密码
alter user root@localhost identified by 'Winner@123456';修改密码
创建用户和数据库
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
-- datasophon元数据库
CREATE DATABASE IF NOT EXISTS datasophon DEFAULT CHARACTER SET utf8;
create user datasophon@'%' identified by 'datasophon';
grant all privileges on *.* to datasophon@'%' with grant option;
FLUSH PRIVILEGES;
-- hive元数据库
CREATE DATABASE IF NOT EXISTS hive DEFAULT CHARACTER SET utf8;
create user hive@'%' identified by 'hive';
grant all privileges on *.* to hive@'%' with grant option;
FLUSH PRIVILEGES;
-- ranger元数据库
CREATE DATABASE IF NOT EXISTS ranger DEFAULT CHARACTER SET utf8;
create user ranger@'%' identified by 'Winner@123456';
grant all privileges on *.* to ranger@'%' with grant option;
FLUSH PRIVILEGES;
-- dolphinscheduler元数据库
CREATE DATABASE IF NOT EXISTS dolphinscheduler DEFAULT CHARACTER SET utf8;
create user dolphinscheduler@'%' identified by 'dolphinscheduler';
grant all privileges on *.* to dolphinscheduler@'%' with grant option;
FLUSH PRIVILEGES;
use dolphinscheduler;
source /opt/datasophon/DDP/packages/dolphinscheduler_mysql.sql;
2.1hive适配
-- 数据库链接地址
javax.jdo.option.ConnectionURL
jdbc:mysql://ddp01:3306/hive?useUnicode=true&allowPublicKeyRetrieval=true&characterEncoding=UTF-8&useSSL=false
-- 初始化数据库
cd bin
./schematool -dbType mysql -initSchema
适配hive需要增加jar包，修改jdbc 连接URL。
2.2ranger适配
初始化SQL文件中添加如下参数：
set global log_bin_trust_function_creators=TRUE;
/home/datasophon/ranger-2.1.0/db/mysql/optimized/current/ranger_core_db_mysql.sql可能报错如下，加上面的参数可避免

3.2DolphinScheduler适配
DolphinScheduler数据库地址:
