FOG installation errors

[Daniel Miller]

@TaTa Actually, what is the result of getenforce?

Was searching around a bit and apparently, SELinux can cause some strange behavior…

Instructions for setting SELinux to permissive or disabled can be found at https://wiki.fogproject.org/wiki/index.php?title=CentOS_7

@Daniel-Miller Thank you for your replies. I already set it to permissive. Changing line 1262 toecho -e "$username:$password" | chpasswd >>$workingdir/error_logs/fog_error_${version}.log 2>&1 solved setting up passsword issue for fogproject account.

I went to update database schema but getting Database connection unavailable. It looks like mysqld is not starting. In /etc/my.cnf files (I can’t find /etc/mysql/my.cnf), socket is pointing to /var/lib/mysql/mysql.sock. I checked mysql.sock and the file exists.

mysql -u root and mysql -u root -p gave me ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

Trying to restart mysql gave me this error: Redirecting to /bin/systemctl restart mysql.service Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

[Daniel Miller]

@TaTa I think your server config file should be at /etc/my.cnf.d/server.cnf.
Can you post the output of systemctl status mysqld.service and journalctl -xe?

[TaTa]

/etc/my.cnf.d/ exists but it contains no files.

@TaTa There should be a log file somewhere in /var/log/mysql/error.log or similar. Please take a look to see why it doesn’t seem to properly start.

[TaTa]

@Sebastian-Roth Thank you for pointing me to the right direction. It was mysqld.pid file that was missing. I created it and re-ran the installation and reached to the point where it asks to update database schema but getting Schema Update Fail. Unable to update schema. I put in the same password during the installation where it asked “Is the MySQL password blank?”. I’m able to mysql -u root -p and put in that same password.

[Sebastian Roth]

@TaTa said in FOG installation errors:

Schema Update Fail. Unable to update schema

Any more information you get about why it fails? Error logs?

[TaTa]

@Sebastian-Roth No error in mysqld log.

[Sebastian Roth]

@TaTa What about Apache und PHP logs?

[Daniel Miller]

You may also have a fog_schema_update_error.log someplace. It looks like schemaupdaterpage.page.php drops that if it encounters an error. I’m not entirely sure where it would drop it, however.

[TaTa]

@Daniel-Miller fog schema update or similar name does not exist in /var/log/fog. Could it be somewhere that I’m not aware of?

[Tom Elliott]

@TaTa under /var/www/fog

[TaTa]

@Tom-Elliott Thank you Tom. It looks like password for fogstorage account password does not meet password policy requirement. Where do I go to change it? I searched in the forums and it looks like there is a fix for it by disabling password validation in mysql https://forums.fogproject.org/topic/11378/fog-show-me-blank-page-on-fresh-install-ubuntu-16-04/12. It would be more ideal if I can change it to a stronger password to meet password policy.

Update ID: 16
Database Error: Failed to query: Error: SQLSTATE[HY000]: General error: 1819 Your password does not satisfy the current policy requirements Error Message: Error Code: "HY000", Error Message: ["HY000",1819,"Your password does not satisfy the current policy requirements"], Debug: SQL: [58] CREATE USER 'fogstorage'@'%' IDENTIFIED BY 'fs30609984138'
Params:  0

[TaTa]

I took are of password policy issue but getting a new error

“HY000”,1396,“Operation CREATE USER failed for ‘fogstorage’@‘%’”]. It doesn’t look like empty hostname as ‘%’.

[TaTa]

I was able to go pass that stage by changing ‘%’ to localhost. I’m not sure if it does any harm. I’m getting “Storage Node Update Warning Unable to connect using ip, user, and/or password provided!” I confirmed that fogproject account has proper access to /images folder. Any thoughts?

[Daniel Miller]

@TaTa The % in the host attribute is the mysql wildcard. This indicates that the user account is allowed to login from any machine. Changing this to localhost means you can only log in from a connection mysql / mariadb explicitly identifies as localhost. Unfortunately, localhost isn’t the only possible identifier possible for a local connection, for example it could use 127.0.0.1, so it is possible that this configuration would deny connections initiated on the same machine, which would result in that storage node warning.

[TaTa]

@Daniel-Miller mysql does not allow using the wildcard. How do i get around it? This might be related to freezing screen when clicking on “Create New Image” and “No master nodes available” when listing all images?

[Daniel Miller]

@TaTa What indicates to you that the wildcard is not allowed? See MySQL’s documentation on creating accounts. It would be helpful to see both the error message encountered as well as the output of select user,host from mysql.user;

[TaTa]

@Daniel-Miller You are right. I checked my other fog server and it does have a wildcard but this one is localhost.

i’m getting this error when creating one using the wildcard (after dropping fogstorage user).
ERROR 1396 (HY000): Operation CREATE USER failed for ‘fogstorage’@‘%’

@TaTa said in FOG installation errors:

ERROR 1396 (HY000): Operation CREATE USER failed for ‘fogstorage’@’%’

No more error message???
