卸载mysql
# rpm -qa|grep mysql mysql-community-common-5.6.30-2.el7.x86_64 mysql-community-libs-5.6.30-2.el7.x86_64 # yum remove mysql-community-libs mysql-community-common
mkdir /var/log/mariadb/
mkdir /var/run/mariadb/
1、在 /etc/yum.repos.d/
下建立 MariaDB.repo,内容如下:
[azureuser@mono etc]$ cd /etc/yum.repos.d
[azureuser@mono yum.repos.d]$ vi MariaDB.repo
# MariaDB 10.0 CentOS repository list - created 2013-08-23 13:08 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
如果是其他的操作系统,可以在这里找到相关信息。
2、使用YUM安装MariaDB
[azureuser@mono yum.repos.d]$ sudo yum -y install MariaDB-client MariaDB-server MariaDB-devel
vi /etc/my.cnf
不要使用中文,用默认的latin1,不然hive会出各种奇怪报错
[mysqld] init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8_unicode_ci skip-character-set-client-handshake [client] default-character-set=utf8 [mysql] default-character-set=utf8 [mysqld_safe] log-error=/var/log/mariadb/mariadb.log pid-file=/var/run/mariadb/mariadb.pid # # include all files from the config directory # !includedir /etc/my.cnf.d
3、启动数据库
[azureuser@mono yum.repos.d]$ sudo service mysql start
启动报错则执行:mysql_install_db --user=mysql --ldata=/var/lib/mysql/
4、修改Root的密码
[azureuser@mono yum.repos.d]$ mysqladmin -u root password ‘passwd’
5、配置远程访问,MariaDB为了安全起见,默认情况下绑定ip( 127.0.0.1)。
[azureuser@mono yum.repos.d]$ mysql -u root -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.0.4-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY ‘passwd’ WITH GRANT OPTION;
MariaDB [(none)]> flush privileges;
第一句中"%"表示任何主机都可以远程登录到该服务器上访问。如果要限制只有某台机器可以访问,将其换成相应的IP即可,如:
GRANT ALL PRIVILEGES ON *.* TO root@"172.168.193.25" IDENTIFIED BY "root";
第二句表示从mysql数据库的grant表中重新加载权限数据。因为MySQL把权限都放在了cache中,所以在做完更改后需要重新加载。
6、如果系统的防火墙开着(or behind a hardware firewall or NAT)你必须放开mysql使用的TCP端口,通常都是3306。
7、大小写敏感
用root帐号登录后,在/etc/my.cnf 中的[mysqld]后添加添加lower_case_table_names=1,重启MYSQL服务,这时已设置成功:不区分表名的大小写;
lower_case_table_names参数详解:
lower_case_table_names = 0
其中 0:区分大小写,1:不区分大小写
