Hello, I’m trying to install “percona-xtradb-cluster-server-5.7” on Ubuntu, but keep running into the same error. I can install no problem on a fresh install og Ubuntu with no MySQL, however if MySQL already exists, I can’t seem to get past this error to install Percona.

[ERROR] Could not open file ‘/var/log/mysqld.log’ for error logging: Permission denied

which results in this:

2018-02-26T19:30:56.324727Z 0 [ERROR] Aborting

How can I install Percona cluster on a system that once that MySQL installed?

Hi,

What version of MySQL you had previously installed (was it community version or the one from the distribution repo)? Can you please share the output of:

```auto
dpkg -l | grep mysql 

```

Hello,

It was the newest version that came with Ubuntu 16.4, It’s no longer installed so I’m unable to get a result from the grep comment. I’ve tried removing the file, reset the permissions and still no luck. Any advice would be great. thanks!

I got this problem also. the solution was to rename the mysqld.log on /etc/mysql/percona-xtradb-cluster.conf.d/mysqld.cnf

change  
log-error=/var/log/mysqld.log

different name

log-error=/var/log/mysqldd.log
