二進制格式安裝過程
(1) 準備用戶
#useradd -s /sbin/nologin -r mysql
(2) 準備數據目錄，建議使用邏輯卷
#mkdir /data/mysql -pv
#chown mysql:mysql /data/mysql
(3) 準備二進制程序
#tar xvf mariadb-10.2.22-linux-x86_64.tar.gz -C /usr/local/ //事先下載好二進制安裝包
#cd /usr/local/
#ln -sv mariadb-10.2.22-linux-x86_64/ mysql
#chown -R root:mysql /usr/local/mysql/
(4) 準備配置文件
#mkdir /etc/mysql/
#cp /usr/local/mysql/support-files/my-huge.cnf /etc/mysql/my.cnf
#vim /etc/mysql/my.cnf
[mysqld]中添加三個選項
datadir=/data/mysql
innodb_file_per_table = on
skip_name_resolve = on //禁止主機名解析，建議使用
(5) 創建數據庫文件
#cd /usr/local/mysql
#./scripts/mysql_install_db --datadir=/data/mysql/ --user=mysql
(6) 準備服務腳本，並啟動服務
#cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
#chkconfig --add mysqld
#service mysqld start （或者 /etc/rc.d/init.d/mysqld start ）
(7) 配置maria環境變量
#echo ‘PATH=/usr/local/mysql/bin:$PATH‘ >> /etc/profile.d/env.sh
#source /etc/profile.d/env.sh
(8) 安全加固
#cd /usr/local/mysql
#./bin/mysql_secure_installation
或者執行下面任意命令給root用戶加密
#./bin/mysqladmin‘ -u root password ‘root‘
#./bin/mysqladmin‘ -u root -h centOS6.magedu.com password ‘root‘
(9) 登陸mariadb數據庫
[root@centOS6 mysql]#mysql -uroot -p
