6 初始化数据库

复制代码
# ./scripts/mysql_install_db --user=mysql --datadir=/data/mariadb_5_5_56
Installing MariaDB/MySQL system tables in '/data/mariadb_5_5_56' ...
250607 10:46:22 [Note] /mariadb/bin/mysqld (mysqld 5.5.56-MariaDB) starting as process 16500 ...
OK
Filling help tables...
250607 10:46:23 [Note] /mariadb/bin/mysqld (mysqld 5.5.56-MariaDB) starting as process 16509 ...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/mariadb/bin/mysqladmin' -u root password 'new-password'
'/mariadb/bin/mysqladmin' -u root -h exam01 password 'new-password'

Alternatively you can run:
'/mariadb/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/mariadb' ; /mariadb/bin/mysqld_safe --datadir='/data/mariadb_5_5_56'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/mariadb/mysql-test' ; perl mysql-test-run.pl

Please report any problems at http://mariadb.org/jira

7 配置启动服务

复制代码
cd support_files
cp mysql.server /etc/init.d/mariadb
vi /etc/init.d/mariadb
修改basedir ,datadir路径

8 加载并启动服务

复制代码

9 修改root密码

复制代码
[root@exam01 mariadb]# '/mariadb/bin/mysqladmin' -u root -h exam01 password 'root'

10 验证登录失败

修改完密码之后测试登录失败,不知道问题在哪

复制代码
[root@exam01 mariadb]# mysql -uroot -hlocalhost -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@exam01 mariadb]#

[root@exam01 mariadb]# mysql -uroot -p -h127.0.0.1
Enter password:

附:

第10步骤 登录失败的原因已经找到,由于第9步修改密码的时候指定了host的主机名。在mysql.user表记录的是root ,exam01

复制代码
MariaDB [(none)]> use mysql;
Database changed
MariaDB [mysql]> 
MariaDB [mysql]> select user,host from user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1       |
|      | exam01    |
| root | exam01    |   <<<<<<<<<<<<<<<<<<
|      | localhost |
| root | localhost |
+------+-----------+
6 rows in set (0.00 sec)

尝试指定host主机名是可以正常登录的。
