CentOS7 安装 玛丽亚DB

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.

CentOS7 安装 MariaDB

CentOS7以上版本上,不再利用MySQL数据库,而是采纳玛丽亚DB数据库,其中玛丽亚DB是MySQL的二个分支.未来写上个体在CentOS7里设置配置MariaDB的步骤:

  1. 下载安装玛丽亚DB

**yum -y install mariadb-server mariadb

  1. 起步玛丽亚DB,并设置root用户的密码:

#启动MariaDB服务
**

[[email protected]
/]# systemctl start mariadb

#安装玛丽亚DB开机专断认同启动
[[email protected]
/]# systemctl enable mariadb

ln -s ‘/usr/lib/systemd/system/mariadb.service’
‘/etc/systemd/system/multi-user.target.wants/mariadb.service’

#测试是还是不是成功运行
[[email protected]
/]# mysql
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.47-MariaDB MariaDB Server

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.

#美高梅集团4688,出于一开始设置玛丽亚DB数据库后, root用户暗中认同密码为空,
所以只必要按Enter键
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.

#是还是不是设置root用户的新密码

Set root password? [Y/n] y

#录入新密码

New password:

#确认新密码

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.

#是否删除匿名用户,生产环境提议删除
Remove anonymous users? [Y/n] y
… Success!

Normally, root should only be allowed to connect from ‘localhost’.
This
ensures that someone cannot guess at the root password from the
network.

#是或不是禁止root远程登录,按照本身的要求选用
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.

#是还是不是删除test数据库
Remove test database and access to it? [Y/n] y

  • 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.

#是或不是再一次加载权限表
Reload privilege tables now? [Y/n] y
… Success!

Cleaning up…

All donewww.4688com,! If you’ve completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

安装 玛丽亚DB
CentOS7上述版本上,不再行使MySQL数据库,而是选拔MariaDB数据库,其中玛丽亚DB是MySQL的3个分支.以后写上个体在CentOS7里设置配置…

一、安装虚拟机

Linux系统:centos7

Disallow root login remotely? [Y/n]
n

… skipping.

Type ‘help;’ or ‘\h’ for help. Type
‘\c’ to clear the current input statement.

Copyright (c) 2000, 2016, Oracle,
MariaDB Corporation Ab and others.

Set root password? [Y/n]
y

New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
… Success!

引进先在虚拟机中测试了将来,再在服务器上搭建环境。

[root@localhost ~]#
mysql_secure_installation

注意:以下安装,我都是用的root权限。

Setting the root password ensures that
nobody can log into the MariaDB
root user without the proper
authorisation.

[root@localhost ~]# mysql -uroot
-p
Enter password:
Welcome to the MariaDB monitor. Commands
end with ; or \g.
Your MariaDB connection id is
11
Server version: 5.5.52-MariaDB MariaDB
Server

二、安装CentOS7

CentOS7查看ip地址的章程为:
ip addr
走访应该是败退的,原因如下:
查了素材,说法是,CentOS7用的是Firewall-cmd,CentOS7以前用的是iptables防火墙;要想让外网能访问到apache主目录,就需求做以下的操作:
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload
接下来再拜访外网ip,就可以了。

七、安装常用的PHP模块
例如,GD库,curl,mbstring,…
1.安装:
yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel
2.重启apache服务
systemctl restart httpd.service
接下来,再一次在浏览器中运作info.php,你会看到安装的模块的音讯;

虚拟机:win10体系自带的杜撰机Hyper-v(虚拟机都几乎)

Reload privilege tables now? [Y/n]
y

… Success!

Enter current password for root (enter
for none):
OK, successfully used password, moving
on…
