安装mariadb,默认是无密码的,但一般是指要设置密码的。在设置密码时出现各种问题,可能还是不太明白其原理。
一下我尝试了两种方法,但都失败了。下面是正确的方法:
1、进入到数据库
[root@localhost etc]# mysql
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 7
Server version: 5.5.41-MariaDB MariaDB Server
Copyright (c) 2000, 2014, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> mysql
-> ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds
to your MariaDB server version for the right syntax to use near 'mysql' at line 1MariaDB [(none)]> update user set password=password("123456")where user='root';
ERROR 1046 (3D000): No database selected
2、选择数据库
MariaDB [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
3、用户root添加密码
MariaDB [mysql]> update user set password=password("toomee")where user='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 4 Changed: 0 Warnings: 0
4、赋予权限
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
5、退出,重新登录
MariaDB [mysql]> exit
Bye
6、登录
mysql -uroot -ptoomee
4、然后创建zabbix库,并设置密码
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'; ////创建zabbix用户并给该用户操作zabbix库的权限 它的密码自己随意起
mysql>flush privileges;
mysql> quit;
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p'zabbix' -D zabbix ////把压缩包导入到创建好的zabbix库里
5、配置文件中修改密码为数据库中设置好的密码
