无法连接到 mysql 服务器 (Percona)

Question

I have installed percona server version 5.7 on my centos 7 .Now when I try to issue following command to connect to the server.

access denied for user 'root'@'localhost'

I have tried to use the --skip-greant-tables to change the password and host from localhost to %. I have tried changing the OS hostname to localhost . I have also tried using --skip-name-resolve .

but still no chance.

any help appreciated

Answer 1

In Percona 5.7, the temporary password is stored in /var/log/mysqld.log so you can find it by:

grep 'temporary password' /var/log/mysqld.log

After that, you can start mysql

sudo systemctl start mysql
sudo /usr/bin/mysql_secure_installation

and use your temporary password to use.

Answer 2

After installing percona, you have to run these commands in order to set password for user root on mysql :

1- sudo systemctl start mysql

2- sudo mysql_secure_installation
