Initial authorization issue in mysql -


i tried multiple ways install mysql , access database on fresh installation. os rhel 7. package used mysql-5.7.7-0.3.rc.el7.x86_64.rpm-bundle.tar

installation process:  [root@host1 mysql]# rpm -ivh mysql-community-common-5.7.7-0.3.rc.el7.x86_64.rpm mysql-community-libs-5.7.7-0.3.rc.el7.x86_64.rpm mysql-community-client-5.7.7-0.3.rc.el7.x86_64.rpm mysql-community-server-5.7.7-0.3.rc.el7.x86_64.rpm  preparing...                          ################################# [100%]  updating / installing... 1:mysql-community-common-5.7.7-0.3.################################# [ 25%] 2:mysql-community-libs-5.7.7-0.3.rc################################# [ 50%] 3:mysql-community-client-5.7.7-0.3.################################# [ 75%] 4:mysql-community-server-5.7.7-0.3.################################# [100%]

then start server

 systemctl start mysqld

after try access server no password root. error as:

[root@host1 mysql]# mysql -u root -p enter password: error 1045 (28000): access denied user 'root'@'localhost' (using password: no)

as have not set password, not sure why error comes. after tried various options , mone me.

option 1 : asks make file , change password using init file. tried using , got output as:

    [root@host1 mysql]# mysqld_safe --init-file=/home/me/mysql-init & [1]28469     -bash: mysqld_safe: command not found

option 2 : set password using mysqladmin command

[root@host1 mysql]# /usr/bin/mysqladmin -u root password mysqladmin: connect server @ 'localhost' failed error: 'access denied user 'root'@'localhost' (using password: no)'

option 3 : using mysql_secure_installation

[root@host1 mysql]#  mysql_secure_installation  securing mysql server deployment.  enter password root user: error: access denied user 'root'@'localhost' (using password: no)

option 4 : mysql -u root 

[root@host1 mysql]# mysql -u root error 1045 (28000): access denied user 'root'@'localhost' (using password: no)

and various others. can please suggest can issue behind this.

for ever in pickle on this:

  1. stop mysql server

  2. create text file onetime.sql contains like:

set password 'root'@'localhost' = password('password789');

path file safe , other users can't it, perhaps /home/jason

  1. start mysql server --init-file option:

mysqld_safe --init-file=/home/jason/onetime.sql &

  1. wait happily while password changed. wait won't long.

  2. delete file ... rm /home/jason/onetime.sql

  3. stop mysql server

  4. start mysql server normal way

edit may necessary :

once mysql has stopped,

edit /etc/my.cnf file add line

skip-grant-tables

restart

connect mysql using root user.

mysql -u root

once logged in, should see following prompt:

mysql>

enter following commands:

mysql> use mysql; mysql> update user set password=password("your new password here") user='root'; mysql> flush privileges; mysql> quit

now stop mysql again:

service mysqld stop

if edited /etc/my.cnf file, delete skip-grant-tables line.

now restart mysql , test new login.

service mysqld restart

mysql -u root -p
