实验环境：
centos7.3主机一台
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 = ONskip_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 *:* LISTEN 0 128 :::22 :::* LISTEN 0 80 :::3306 :::*
安全初始化
]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, we'll need the currentpassword for the root user. If you've just installed MariaDB, andyou 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 MariaDBroot 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 anyoneto log into MariaDB without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.Remove anonymous users? [Y/n] y ... Success!Normally, root should only be allowed to connect from 'localhost'. Thisensures 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 canaccess. This is also intended only for testing, and should be removedbefore 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 farwill take effect immediately.Reload privilege tables now? [Y/n] ... Success!Cleaning up...All done! If you've completed all of the above steps, your MariaDBinstallation should now be secure.Thanks for using MariaDB!
