Centos7 YUM安装MariaDB 10.0
安装步骤(新装)
配置添加yum源文件
vim /etc/yum.repos.d/mariadb.repoMariaDB 10.0 CentOS repository list - created 2016-05-30 02:16 UTC# http://downloads.mariadb.org/mariadb/repositories/
[mariadb] name = MariaDB #baseurl = http://yum.mariadb.org/10.0/centos7-amd64 baseurl = http://archive.mariadb.org/mariadb-10.0.10/yum/centos6-amd64/ gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck= 0
其他版本请参照官网修改版本号
查配置yum源对应的mariadb版本是否正确
yum makecache yum info MariaDB-server
安装MariaDB-server和Client
yum install MariaDB-server MariaDB-client MariaDB-devel -y 注：如果有提示和以前安装的版本冲突，您可能需要先移除以前安装的包，例如: yum remove mariadb-libs.
新建数据目录并创建mysql用户
mkdir -p /data/dbdata/data/ && useradd mysql -s /sbin/nologin
初始化数据库目录
mysql_install_db --datadir='/data/dbdata/data/'
修改权限并手工命令启动
chown mysql:mysl /data/dbdata/data/ -R cd '/usr' ; /usr/bin/mysqld_safe --datadir='/data/dbdata/data/' &
初始化数据库权限
mysql_secure_installation

初始化数据库权限
mysql_secure_installation --defaults-file=/etc/mariadb/etc/my.cnf
或者
mysql -h 127.0.0.1 -uroot -p -P3307
grant all privileges on *.* to 'root'@'localhost' identified by 'password';
grant all privileges on *.* to 'root'@'127.0.0.1' identified by 'password';
flush privileges ;
