实验环境：

1. centos7.3主机一台

2. http://mariadb.org/ 下载最新源码包mariadb10.2.8

准备二进制程序

]# rz      <===上传，来自lrzsz包
]# tar xvf mariadb-10.2.8-linux-x86_64.tar.gz -C /usr/local/   <===-C 指定的路径必须是这个，源码里面定义的就是这个
]# cd /usr/local/
]# ln -s mariadb-10.2.8-linux-x86_64/ mysql

用户准备

]# useradd -r -m -d /app/mysqldb -s /sbin/nologin mysql   <===指定用户家目录为数据库存放路径/app/mysqldb

准备配置文件

]#mkdir /etc/mysql
]#cp /usr/local/mysql/support-files/my-large.cnf /etc/mysql/my.cnf
]# vim /etc/mysql/my.cnf
[mysqld]
datadir               = /app/mysqldb  <===必须要添加的
innodb_file_per_table = ON
skip_name_resolve     = ON        <===禁止主机名解析

创建数据库文件

]#cd /usr/local/mysql/
]#scripts/mysql_install_db --datadir=/app/mysqldb --user=mysql

配置环境变量

]# vi /etc/profile.d/mysql.sh
PATH=/usr/local/mysql/bin:$PATH

准备日志文件

]#mkdir /var/log/mariadb
]#chown mysql /var/log/mariadb/

准备服务脚本启动服务

]# cd /usr/local/mysql/
]# cp support-files/mysql.server /etc/init.d/mysqld
]#service mysqld start
]# ss -tanl            <===数据库监听在3306端口
State       Recv-Q Send-Q          Local Address:Port           Peer Address:Port
LISTEN      0      128                         *:22              *:*

安全初始化

]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y... Success!
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]  ... Success!
Cleaning up...
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
