执行之后发现报错，还是在图7显示页面，我们可以看见Step by step installation: 段落结束之后有这么一句： 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: mariadb-libs < 1:10.1.21-1.el7.centos conflicts with MariaDB-common-10.1.21-1.el7.centos.x86_64是不是和我们的错误很相似？按照官方提供的solution就可以解决了。
后续还有几个错误，同样按照官方给出的解决方案处理，一步一步就搞定了，如下：
[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -qa | grep mariadb-libs mariadb-libs-5.5.60-1.el7_5.x86_64 [root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ev --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64 Preparing packages... mariadb-libs-1:5.5.60-1.el7_5.x86_64 [root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -qa | grep mariadb-libs [root@iZ2ze7s2v0b78922wia32rZ mariadb]# yum install boost-devel.x86_64 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ... Is this ok [y/d/N]: y ... Complete! [root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm --import然后重新回到安装的第四步：
[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 error: Failed dependencies: libaio.so.1()(64bit) is needed by MariaDB-client-10.4.8-1.el7.centos.x86_64 libaio.so.1(LIBAIO_0.1)(64bit) is needed by MariaDB-client-10.4.8-1.el7.centos.x86_64 libaio.so.1(LIBAIO_0.4)(64bit) is needed by MariaDB-client-10.4.8-1.el7.centos.x86_64 libaio.so.1()(64bit) is needed by MariaDB-server-10.4.8-1.el7.centos.x86_64 libaio.so.1(LIBAIO_0.1)(64bit) is needed by MariaDB-server-10.4.8-1.el7.centos.x86_64 libaio.so.1(LIBAIO_0.4)(64bit) is needed by MariaDB-server-10.4.8-1.el7.centos.x86_64发现还是报错？？？
这个是官方在10.4.8中新引入的一个问题,需要下载一个依赖包libaio:
[root@iZ2ze7s2v0b78922wia32rZ mariadb]# wget --2019-11-28 10:52:26--下载成功之后，安装一下当前下载的依赖包：
[root@iZ2ze7s2v0b78922wia32rZ mariadb]# rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm然后再一次重复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 Preparing... ################################# [100%] Updating / installing... 1:MariaDB-compat-10.4.8-1.el7.cento################################# [ 20%] 2:MariaDB-common-10.4.8-1.el7.cento################################# [ 40%] 3:MariaDB-client-10.4.8-1.el7.cento################################# [ 60%] 4:galera-4-26.4.3-1.rhel7.el7.cento################################# [ 80%] 5:MariaDB-server-10.4.8-1.el7.cento################################# [100%] Two all-privilege accounts were created.

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 See the MariaDB Knowledgebase at or the MySQL manual for more instructions. Please report any problems at The latest information about MariaDB is available at You can find additional information about the MySQL part at: Consider joining MariaDB's strong and vibrant community: https://mariadb.org/get-involved/终于安装成功了。。。
接下来，最后一步配置数据库：
# 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! 测试登录数据库：
[root@iZ2ze7s2v0b78922wia32rZ ~]# mysql -u root -p
