CentOS7安装MariaDB的流程步骤
2024-06-06 02:04:25
安装前需要彻底清除你的服务器计算机上原来安装过的mysql、maraidb的文件，不然会出现各种问题。
CentOS7安装MariaDB的流程步骤如下：
====================================================
执行安装命令:
yum -y install mariadb*- 注意事项（这一步不是必须的，出现时可以这样尝试着解决）
*mariadb 错误 [Errno 5] [Errno 12] Cannot allocate memory
*一般云服务器内存很低，可以设置一下vi /etc/my.cnf[mysqld]innodb_buffer_pool_size=50M
- 注意事项（这一步不是必须的，出现时可以这样尝试着解决）
开机自动启动MariaDB：
systemctl enable mariadb启动MariaDB：
systemctl start mariadb查看MariaDB状态：
systemctl status mariadb初次安装数据库，进行数据库配置：
mysql_secure_installation- 提示：
– 第一次操作直接回车
– 第二次Set root password?[Y/n] 输入Y
– New password: 输入你的密码
– 确认密码 - Success!
登录数据库：
mysql -uroot -p设置字符集（建议设置为：UTF-8）：
vim /etc/my.cnf- [mysqld]后面追加以下内容
init_connect='SET collation_connection = utf8_unicode_ci'init_connect='SET NAMES utf8'character-set-server=utf8collation-server=utf8_unicode_ciskip-character-set-client-handshake
修改文件：
vim /etc/my.cnf.d/client.cnf- [client] 后面追加以下内容
default-character-set=utf8
- [client] 后面追加以下内容
修改文件：
vim /etc/my.cnf.d/mysql-clients.cnf- [mysql] 后面追加以下内容
default-character-set=utf8
- [mysql] 后面追加以下内容
接着重启服务生效：
systemctl restart mariadbMYSQL客户端进入，查看字符集：
- 登录进入：
show variables like "%character%";show variables like "%collation%";
- 登录进入：
如果要开放远程登录，得开放防火墙，允许3306访问：
firewall-cmd --permanent --zone=public --add-port=3306/tcpfirewall-cmd --reload
MYSQL客户端进入修改权限，允许远程登录：
- 【选择使用mysql数据库】
use mysql; - select user,host from user;
- 【修改权限】
update user set host='%' where host='localhost'; - select user,host from user;
- 【刷新使得权限生效】
flush privileges;
- 【选择使用mysql数据库】
测试：在其他计算机远程登录
mysql -h域名 -uroot -p
good luck!
你可能遇到的错误：
- CentOS 7 MariaDB Error “Failed to start mariadb.service: Unit not found.” [closed]
- 错误 [Errno 5] [Errno 12] Cannot allocate memory
解决办法都是： 请检查你的计算机是否有残留的mysql或者mariadb版本的文件（特别是一些云服务器初始化时可能自带的相关版本）
以下是整个安装流程，供参考：

[root@iZwz9edz6cpxxf0o19aqisZ app]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS 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):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
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] n... skipping.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] n... skipping.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!CentOS7安装MariaDB的流程步骤相关推荐
