最终的url点击之后，就可以看到如下图所示界面：

本来完全可以提供最终的一个url，提供一步一步点击的按钮连接，是为了方便大家来学习路线思路，而不能只拿结果。
还记得我们之前第二步看到的一堆rpm包吗？下载第三步方框中的package,当然，这个文档的版本稍有点落后，但是我们只需要搜索前缀名称就行了，比如搜索client:

我们下载最新版本就可以了。
接下来进入正式步骤了哦～：
在图7中有Step by step installation:

Step by step installation:

1) First install all of the dependencies needed. Its easy to do this via YUM packages: yum install rsync nmap lsof perl-DBI nc

2) rpm -ivh jemalloc-3.6.0-1.el7.x86_64.rpm

3) rpm -ivh jemalloc-devel-3.6.0-1.el7.x86_64.rpm

4) rpm -ivh MariaDB-10.1.21-centos7-x86_64-common.rpm MariaDB-10.1.21-centos7-x86_64-compat.rpm MariaDB-10.1.21-centos7-x86_64-client.rpm galera-25.3.19-1.rhel7.el7.centos.x86_64.rpm MariaDB-10.1.21-centos7-x86_64-server.rpm

Follow the steps we begin:

Installation dependency information, the command line:

[root@iZ2ze7s2v0b78922wia32rZ software]#  yum install rsync nmap lsof perl-DBI nc

Before we install the downloaded versionjemalloc-3.6.0-1.el7.x86_64.rpm

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh jemalloc-3.6.0-1.el7.x86_64.rpm

installationjemalloc-devel-3.6.0-1.el7.x86_64.rpm

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh jemalloc-devel-3.6.0-1.el7.x86_64.rpm

Install the remaining mariadb relevant packages must pay attention to the order.common > compat > client > galera > server

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh MariaDB-common-10.4.8-1.el7.centos.x86_64.rpm MariaDB-compat-10.4.8-1.el7.centos.x86_64.rpm MariaDB-client-10.4.8-1.el7.centos.x86_64.rpm galera-4-26.4.3-1.rhel7.el7.centos.x86_64.rpm MariaDB-server-10.4.8-1.el7.centos.x86_64.rpm

After performing a discovery error, or display the page in Figure 7, we can see that Step by step installation:there is such a sentence after the end of the paragraph:Here is the error message for dependencies:

# rpm -ivh MariaDB-10.1.21-centos7-x86_64-common.rpm 
warning: MariaDB-10.1.21-centos7-x86_64-common.rpm: Header V4 DSA/SHA1 Signature, key ID 1bb943db: NOKEY
error: Failed dependencies:

Is not our fault and very similar? According to the official solution can be resolved.

There are also several follow-up error, according to the same solution given by the official process, step by step to get, as follows:

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -qa | grep mariadb-libs
mariadb-libs-5.5.60-1.el7_5.x86_64

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm --import http://yum.mariadb.org/RPM-GPG-KEY-MariaDB

Then back to the fourth step of the installation:

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh MariaDB-common-10.4.8-1.el7.centos.x86_64.rpm MariaDB-compat-10.4.8-1.el7.centos.x86_64.rpm MariaDB-client-10.4.8-1.el7.centos.x86_64.rpm galera-4-26.4.3-1.rhel7.el7.centos.x86_64.rpm MariaDB-server-10.4.8-1.el7.centos.x86_64.rpm

Found or an error? ? ?

This is the official in 10.4.8question in the introduction of new, need to download a dependent package libaio:

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# wget http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm
--2019-11-28 10:52:26--  http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm

After a successful download, install what the current download dependencies:

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

Then again repeat Step 4:

[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh MariaDB-common-10.4.8-1.el7.centos.x86_64.rpm MariaDB-compat-10.4.8-1.el7.centos.x86_64.rpm MariaDB-client-10.4.8-1.el7.centos.x86_64.rpm galera-4-26.4.3-1.rhel7.el7.centos.x86_64.rpm MariaDB-server-10.4.8-1.el7.centos.x86_64.rpm

Two all-privilege accounts were created.
One is root@localhost, it has no password, but you need to
be system 'root' user to connect. Use, for example, sudo mysql
The second is mysql@localhost, it has no password either, but
you need to be the system 'mysql' user to connect.
After connecting you can set the password, if you would need to be
able to connect as any of these users with a password and without sudo

Next, the final step in the configuration database:

# 启动mariaDB,(因为mariaDB是mysql作者写的新的数据库，其实服务和mysql是一样的，所以启动使用的是下面)
[root@iZ2ze7s2v0b78922wia32rZ ~]# service mysql start
# 安全配置
[root@iZ2ze7s2v0b78922wia32rZ ~]# mysql_secure_installation
# 输入root密码，安装后第一次启动为空，直接回车
Enter current password for root (enter for none): 
# step 1： 是否切换到unix_socket安全认证，否
Switch to unix_socket authentication [Y/n] n
# step 2: 更改密码，选择修改
Change the root password? [Y/n] y
# step 3: 移除匿名用户，选择是
Remove anonymous users? [Y/n] y
# step 4: 是否允许root远程登录，根据个人需求，因为我是测试服务器选择允许
Disallow root login remotely? [Y/n] y
# step 5: 移除test数据库
Remove test database and access to it? [Y/n] y
# step 6: 重新加载权限表
Reload privilege tables now? [Y/n] y
# 看到下面，说明成功啦！！！
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
