6.  ##### 安装 MariaDB 并初始化 #####
    
        [root@cdh01 mariadb]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mariadb --datadir=/usr/local/mariadb/data
        Installing MariaDB/MySQL system tables in '/usr/local/mariadb/data' ...
        OK
        
        To start mysqld at boot time you have to copy
        support-files/mysql.server to the right place for your system
        ...
    
    参考: https://mariadb.com/kb/en/library/mysql\_install\_db/
7.  ##### 创建mysqld #####
    
        [root@cdh01 mariadb]# cp ./support-files/mysql.server /etc/init.d/mysqld
        [root@cdh01 mariadb]# ll /etc/init.d/mysqld
        -rwxr-xr-x 1 root root 12245 Dec 19 13:46 /etc/init.d/mysqld   # 是否可执行
8.  ##### 设置为开机启动 #####
    
        [root@cdh01 mariadb]# chkconfig --list mysqld
        
        Note: This output shows SysV services only and does not include native
              systemd services. SysV configuration data might be overridden by native
              systemd configuration.
        
              If you want to list systemd services use 'systemctl list-unit-files'.
              To see services enabled on particular target use
              'systemctl list-dependencies [target]'.
        
        service mysqld supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add mysqld')
        # 添加到系统服务 chkconfig
        [root@cdh01 mariadb]# chkconfig --add mysqld
        [root@cdh01 mariadb]# chkconfig --list mysqld

              If you want to list systemd services use 'systemctl list-unit-files'.
              To see services enabled on particular target use
              'systemctl list-dependencies [target]'.
        
        mysqld         	0:off	1:off	2:on	3:on	4:on	5:on	6:off
        [root@cdh01 mariadb]# service mysqld restart
        Restarting mysqld (via systemctl):                         [  OK  ]
9.  ##### 配置环境变量 #####
    
        [root@cdh01 mariadb]# vim /etc/profile
    
        #set mariadb environment
        export MARIADB_HOME=/usr/local/mariadb
        export PATH=$PATH:${MARIADB_HOME}/bin
    
        [root@cdh01 mariadb]# source /etc/profile
10. ##### 配置 MariaDB #####
    
        # -bash: ./bin/mariadb-secure-installation: No such file or directory
        # 报上述问题，请使用 ./bin/mysql_secure_installation
        [root@cdh01 mariadb]# ./bin/mariadb-secure-installation --basedir=/usr/local/mariadb
        print: /usr/local/mariadb/bin/my_print_defaults
        
        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
        haven't set the root password yet, you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have your root account protected, so you can safely answer 'n'. Switch to unix_socket authentication [Y/n] Y Enabled successfully! Reloading privilege tables.. ... Success! You already have your root account protected, so you can safely answer 'n'. Change the 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. 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] n ... skipping. 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] Y ... 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!
