(8)修改配置文件，加入几个常用参数。
[root@node2 mysql]# cp /usr/local/mysql/support-files/my-large.cnf /etc/my.cnf [root@node2 ~]# vim /etc/my.cnf [mysqld] datadir=/datadir user=mysql skip_name_resolve innodb_file_per_table(9)启动数据库
[root@node2 ~]# service mysqld start Starting MySQL.161210 08:44:14 mysqld_safe Logging to '/datadir/node2.bc.com.err'. SUCCESS!启动成功！
注意的是，先启动MySQL是无法进行下一步安全设置的。
因为你想想不开服务，怎么改密码和清除示例。
(10)初始化安全设置
[root@node2 ~]# 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] Y 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.
