CentOS 8.2: Error Running Non-shared Postrotate Script For /var/log/mysql/mysqld.log
Home » CentOS » CentOS 8.2: Error Running Non-shared Postrotate Script For /var/log/mysql/mysqld.log
Hello fellow CentOS users!
I have installed CentOS 8.2.2004 with the following packages:
mysql-common-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64
mysql-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64
mysql-errmsg-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64
mysql-server-8.0.21-1.module_el8.2.0+493+63b41e36.x86_64
Then I have run mysql_secure_installation and among other things set the root password for MySQL
As result I am greeted with the following anachron mail every morning:
/etc/cron.daily/logrotate:
mysqladmin: connect to server at ‘localhost’ failed error: ‘Access denied for user ‘root’@’localhost’ (using password: NO)’
error: error running non-shared postrotate script for
/var/log/mysql/mysqld.log of ‘/var/log/mysql/mysqld.log ‘
I understand that the reason is me having set the root password for MySQL.
But my question is how to provide the password to postrotate without disclosing it too much?
Other than that the MySQL works well, I use it to host 3 WordPress websites at my CentOS 8 Linux server (haproxy -> Jetty x 3 -> FastCGI -> php-fpm ->
Wordpress -> MySQL)
Greetings from Germany Alex

Hallo Alex,
take a look into /etc/logrotate.d/mysqld
Maybe using unix_socket for root user?

In article, Alexander Farber wrote:
Create a file .my.cnf owned by root with permission 600, containing these lines:
[mysqladmin]
user = root password = YourMySqlRootPassword
You need to put it in / or in /root – I usually do both, as I think logrotate has / as it’s home dir instead of /root.
Then logrotate can call mysqladmin without having to give a password.
