1) 安装MariaDB v10.2
[root@netdisk ~]# yum install yum-plugin-prioritiesyum centos-release-scl-rh centos-release-scl -y
[root@netdisk ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo
[root@netdisk ~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo
[root@netdisk ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo
[root@netdisk ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo<br>
[root@netdisk ~]# yum --enablerepo=centos-sclo-rh install rh-mariadb102-mariadb-server -y
1) 加载MariaDB v10.2的shell环境
[root@netdisk ~]# scl enable rh-mariadb102 bash
[root@netdisk ~]# mysql -V
mysql Ver 15.1 Distrib 10.2.22-MariaDB, for Linux (x86_64) using EditLine wrapper
[root@netdisk ~]# vim /etc/profile.d/mariadb102.sh
source /opt/rh/rh-mariadb102/enable
export X_SCLS="`scl enable rh-mariadb102 'echo $X_SCLS'`"
[root@netdisk ~]# source /etc/profile.d/mariadb102.sh
[root@netdisk ~]# vim /etc/opt/rh/rh-mariadb102/my.cnf.d/mariadb-server.cnf
# 于[mysqld]最尾部追加如下内容:
character-set-server=utf8
[root@netdisk ~]# systemctl enable --now rh-mariadb102-mariadb
2) 初始化MariaDB v10.2
[root@netdisk ~]# mysql_secure_installation
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): # enter
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 # 设置root密码
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 # 移除anonymous账户
... 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] y # 禁用root远程登录
... Success!
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 # 移除test数据库
- 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 # 重新加载privilege
... 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!
