NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

安装mariadb报错
CentOS7版本安装MariaDB出现错误：Failed to start mariadb.service: Unit not found
首先查看安装rpm -qa| grep mariadb 是否安装成功
出现此问题是由于安装mariadb数据库时未安装mariadb-server服务器
执行命令yum install mariadb-server
执行systemctl start mariadb
查看是否成功启动，如果还有报错，是由于之前安装mysql导致，需要卸载
#查看mysql
rpm -qa|grep -i mysql

#开始卸载
yum remove mysql-community-common-5.7.29-1.el7.x86_64
yum remove mysql-community-client-5.7.29-1.el7.x86_64

yum remove mysql-community-libs-5.7.29-1.el7.x86_64
yum remove mysql-community-server-5.7.29-1.el7.x86_64
#查看是否卸载完成
rpm -qa |grep -i mysql
#查找mysql相关目录
# find / -name mysql

#删除相关目录
rm -rf /var/lib/mysql
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
#删除/etc/my.cnf
rm -rf /etc/my.cnf
#删除/var/log/mysqld.log（如果不删除这个文件，会导致新安装的mysql无法生存新密码，导致无法登陆）
rm -rf /var/log/mysqld.log
#再次查找机器是否安装mysql
rpm -qa|grep -i mysql
