實驗環境：
centos7.3主機一臺
http://mariadb.org/ 下載最新源碼包mariadb10.2.8
準備二進制程序
]# rz <===上傳，來自lrzsz包 ]# tar xvf mariadb-10.2.8-linux-x86_64.tar.gz -C /usr/local/ <===-C 指定的路徑必須是這個，源碼裏面定義的就是這個 ]# cd /usr/local/ ]# ln -s mariadb-10.2.8-linux-x86_64/ mysql
用戶準備
]# useradd -r -m -d /app/mysqldb -s /sbin/nologin mysql <===指定用戶家目錄爲數據庫存放路徑/app/mysqldb
準備配置文件
]#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 <===必須要添加的 innodb_file_per_table = ON skip_name_resolve = ON <===禁止主機名解析
創建數據庫文件
]#cd /usr/local/mysql/ ]#scripts/mysql_install_db --datadir=/app/mysqldb --user=mysql
配置環境變量
]# vi /etc/profile.d/mysql.sh PATH=/usr/local/mysql/bin:$PATH
準備日誌文件
]#mkdir /var/log/mariadb ]#chown mysql /var/log/mariadb/
準備服務腳本啓動服務
]# cd /usr/local/mysql/ ]# cp support-files/mysql.server /etc/init.d/mysqld ]#service mysqld start ]# ss -tanl <===數據庫監聽在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 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!
