CentOS使用rpm离线安装mariadb

本文不再更新，可能存在内容过时的情况，实时更新请移步原文地址：CentOS使用rpm离线安装mariadb；

环境：

CentOS Linux release 7.6.1810 (Core)
mariadb:10.4.7

安装过程中我是使用root用户操作的。

依赖

离线安装不容易啊，按照官方文档：Installing MariaDB With the rpm Tool 的意思，是需要jemalloc、MariaDB*、galera等，但是我只用到了下面的依赖，没有装jemalloc*。文件可以自行 Google，总结就是，缺什么装什么。

boost-program-options-1.53.0-27.el7.x86_64.rpm(galera需要)

galera-4-26.4.0-1.rhel7.el7.centos.x86_64.rpm

perl-Compress-Raw-Bzip2-2.061-3.el7.x86_64.rpm

perl-Data-Dumper-2.145-3.el7.x86_64.rpm

perl-DBI-1.627-4.el7.x86_64.rpm

perl-IO-Compress-2.061-2.el7.noarch.rpm

perl-Net-Daemon-0.48-5.el7.noarch.rpm

perl-PlRPC-0.2020-14.el7.noarch.rpm

perl-Compress-Raw-Zlib-2.061-4.el7.x86_64.rpm

下载

下载地址：http://downloads.mariadb.org/ ，选择适合自己的镜像地址进行下载。

MariaDB-client-10.4.7-1.el7.centos.x86_64.rpm

MariaDB-devel-10.4.7-1.el7.centos.x86_64.rpm

MariaDB-server-10.4.7-1.el7.centos.x86_64.rpm

MariaDB-shared-10.4.7-1.el7.centos.x86_64.rpm

标准的服务端至少要下载client、shared和server，点击这里查看各个rpm的含义。

卸载旧版本Mysql

安装之前，旧版本的MYSQL会与MariaDB有冲突，因此需要先卸载MYSQL。检查是否安装：

rpm -qa 'mysql*'

安装依赖

rpm -ivh boost-program-options-1.53.0-27.el7.x86_64.rpm

rpm -ivh galera-4-26.4.0-1.rhel7.el7.centos.x86_64.rpm

rpm -ivh perl*

安装MariaDB

rpm -ivh MariaDB-*

启动服务

systemctl start mariadb #立刻启动

systemctl enable mariadb #开机启动

systemctl status mariadb #查看服务状态

设置root密码

/usr/bin/mysqladmin -u root password '1234567890'

通过修改mysql数据库，配置实现远程连接：

[root@localhost seafile-env]# /usr/bin/mysql -u root -p

Enter password:

Database changed

MariaDB [mysql]> grant all privileges  on *.* to root@'localhost' identified by "Passw0rd";

Query OK, 0 rows affected (0.098 sec)

MariaDB [mysql]> grant all privileges  on *.* to root@'%' identified by "Passw0rd";

Query OK, 0 rows affected (0.028 sec)

MariaDB [mysql]> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.001 sec)

MariaDB [mysql]>

测试连接

如果连接失败，可能是端口没有开放的原因，默认端口是3306，参考这篇文章：CentOS开放端口的方法，对端口进行放开。
