查看系统里有没有安装mariadb

二进制格式安装过程
(1) 准备用户
#useradd -s /sbin/nologin -r mysql

(2) 准备数据目录，建议使用逻辑卷
#mkdir /data/mysql -pv
#chown mysql:mysql /data/mysql

(3) 准备二进制程序
#tar xvf mariadb-10.2.22-linux-x86_64.tar.gz -C /usr/local/ //事先下载好二进制安装包
#cd /usr/local/
#ln -sv mariadb-10.2.22-linux-x86_64/ mysql
#chown -R root:mysql /usr/local/mysql/

(4) 准备配置文件
#mkdir /etc/mysql/
#cp /usr/local/mysql/support-files/my-huge.cnf /etc/mysql/my.cnf

#vim /etc/mysql/my.cnf
[mysqld]中添加三个选项
datadir=/data/mysql
innodb_file_per_table = on
skip_name_resolve = on //禁止主机名解析，建议使用

(5) 建立数据库文件
#cd /usr/local/mysql
#./scripts/mysql_install_db --datadir=/data/mysql/ --user=mysql

(6) 准备服务脚本，并启动服务
#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环境变量
#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

或者执行下面任意命令给root用户加密
#./bin/mysqladmin' -u root password 'root'
#./bin/mysqladmin' -u root -h centOS6.magedu.com password 'root'

(9) 登录mariadb数据库
[root@centOS6 mysql]#mysql -uroot -p
