# 编译安装
make&&make install

# 进入安装目录
cd /usr/local/mariadb/
# 创建启动文件
cp support-files/mysql.server /etc/init.d/mysqld
# 添加执行权限
chmod +x /etc/init.d/mysqld
# 创建存放数据表目录
mkdir -p mkdir /usr/local/mariadb/mysqldata/
# 创建存放mysql.sock目录
mkdir -p mkdir /usr/local/mariadb/tmp/
# 修改mariadb目录权限
chown -R mysql:mysql /usr/local/mariadb/
# 创建mariadb配置文件

OK
 
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
 
 
Two all-privilege accounts were created.
One is root@localhost, it has no password, but you need to
be system 'root' user to connect. Use, for example, sudo mysql
The second is root@localhost, it has no password either, but
you need to be the system 'root' user to connect.
After connecting you can set the password, if you would need to be
able to connect as any of these users with a password and without sudo
 
See the MariaDB Knowledgebase at https://mariadb.com/kb or the
MySQL manual for more instructions.
 
You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/usr/local/mariadb/mysqldata'
 
You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl
