CentOS6.5系统安装MariaDB数据库详细步骤

 1、软件环境： CentOS 6.5 x64
MariaDB 5.5.36
2、安装过程 1）在/etc/yum.repos.d/目录创建MariaDB.repo文件，内容如下：
# MariaDB 5.5 CentOS repository list - created 2014-03-04 11:20 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
2）在Shell环境下执行命令
# yum install MariaDB-server MariaDB-client

Error in PREIN scriptlet in rpm package MariaDB-server-5.5.36-1.el6.x86_64
******************************************************************
A MySQL or MariaDB server package (mysql-server-5.1.71-1.el6.x86_64) is installed.
The current MariaDB server package is provided by a different
vendor (CentOS) than Monty Program AB.  Some files may be installed
to different locations, including log files and the service
startup script in /etc/init.d/.
Upgrading directly from MySQL 5.1 to MariaDB 5.5 may not
be safe in all cases.  A manual dump and restore using mysqldump is
recommended.  It is important to review the MariaDB manual's Upgrading
section for version-specific incompatibilities.
A manual upgrade is required.
- Ensure that you have a complete, working backup of your data and my.cnf
  files
- Shut down the MySQL server cleanly
- Remove the existing MySQL packages.  Usually this command will
  list the packages you should remove:
  rpm -qa | grep -i '^mysql-'
  You may choose to use 'rpm --nodeps -ev ' to remove
  the package which contains the mysqlclient shared library.  The
  library will be reinstalled by the MariaDB-shared package.
- Install the new MariaDB packages supplied by Monty Program AB
- Ensure that the MariaDB server is started
- Run the 'mysql_upgrade' program
This is a brief description of the upgrade process.  Important details
can be found in the MariaDB manual, in the Upgrading section.

3、启动MariaDB
# /etc/init.d/mysqld start
Initializing MySQL database:  WARNING: The host 'Cloud-Q2' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h Cloud-Q2 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]
4、为MariaDB设置密码
# /usr/bin/mysqladmin -u root password 'adminadmin'
登陆MariaDB
MySQL [(none)]> use mysql;
MySQL [mysql]> update user set host='%' where user='root' and host='127.0.0.1';
MySQL [mysql]> grant all privileges on *.* to 'root'@'%' identified by 'adminadmin' with grant option;
MySQL [mysql]> flush privileges;
5、让防火墙通过3306端口
# vi /etc/sysconfig/iptables
添加如下内容：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
保存并退出编辑
重启防火墙服务
# service iptables restart
远程连接检查，一切OK！
