PHP error Uncaught Exception: DateTimeZone

[kortnor]

Dear all,

I’m making a fresh install based on https://wiki.fogproject.org/wiki/index.php?title=CentOS_7 on fog trunk

os: centos 7
php verson : 7
I try to set up the last version on the git --> git pull last version
What other information you need ?

Step during the installation:

 * You still need to install/update your database schema.
 * This can be done by opening a web browser and going to:

   http://10.10.0.15/fog/management

 * Press [Enter] key when database is updated/installed.

I go to the following webpage with firefox http://10.10.0.15/fog/management/?node=schemaupdater

error encountered during the installation in /var/log/httpd/error_log:

I’ll bet if you lick one line before that it will show something along the lines of: mysql couldn’t login.

[Tom Elliott]

@kortnor What I mean is the errors you’re seeing, the http error log, will have somewhere before the start of the datetimezone stuff, mysql unable to be logged into. The backing up database code is not a real good indicator as it’s using the data but not properly “failing”. THe DB Backup file will likely be 0 bytes.

[kortnor]

@Tom-Elliott

ok, then where can I find this information? or better is the mysql procedure handeled with the root user or with the fog user? like fog is creating the stuff on it

also I don’t see anything strange in the mysqld.log neither in the foginstall.log

EDIT

indeed there is another error

[Mon Mar 14 23:00:08.367265 2016] [:error] [pid 5160] [client 10.10.0.2:50430] PHP Warning:  mysqli::real_connect(): MySQL server has gone away in /var/www/html/fog/lib/db/mysql.class.php on line 30

EDIT 2:
WHen I restart the install
the script fails on backing up database
however there are no database fog in mysql ( show databases )

[kortnor]

I’m wondering if the cause isn’t that now centos 7 has also passed to mariadb and fog should target the mariadb and mariadb-server package
Am I right?

Also with mysql 5.4 on centos 7, everytime you restarting your host, the folder /var/run/mysqld and the file /var/run/mysqld/mysqld.pid are disapearing

[Tom Elliott]

I’m not following.

CentOS 7 should be using the remi repository (of late it’s been a real pain to try to handle – don’t know why, I just know that it has been.) I’ve updated the code as I did have one error that might prevent the php packages from installing properly. We NEVER want to use 5.4 any more, if we can help it, which is why I started installing the remi repo to begin with.

The mysql/mysql-server || mariadb/mariadb-server should automatically be chosen properly.

Don’t know what you mean by:

The /var/run/mysqld/mysqld.pid are disappearing? What do you mean by this. Normally the /run partition is mounted to a tmpfs space which is essentially loaded into RAM. Those files disappearing shouldn’t impede operation of mysql/mariadb instances though. CentOS 7, by default, installs mariadb even if you call mysql to be installed.

[Sebastian Roth]

I just ran into the same issue - yeah replicated! In /etc/php.ini there is no timezone defined. Lookes like this:

...
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
;date.timezone =
...

Changed it to date.timezone = Europe/Berlin (removed the leading ;) and systemctl restart httpd.service fixed this for me!

@Tom-Elliott
I’ve noticed ( at least on a fresh installation ) that when I install centos 7 minimal on a vm (virtual box ) that when I restart the vm and I restart the mysqld daemon that he indicates me the mysqld.pid can’t be created because there is not mysqld folder in /var/run

now i’ve tried to clean the actual centos 7 from mysql meaning by that a yum remove mysql mysql-* and also delete the /var/lib/mysql
Then Ive installed mariadb ( mariadb-server mariadb-libs mariadb) with yum and configured with :

after I try a reinstallation of the trunk ( before I make a git pull in order to be sure I’m on the last version ) then I receive the following error

I would like to know also, if the script detect the specific version of centos family or does he embed it in redhat ( Base linux: Red Hat )

[Sebastian Roth]

@kortnor Please check your /opt/fog/.fogsettings file. I guess it says:

...
packages='... mysql mysql-server...'
...

Forcing the installer to try and install mysql. Just remove the .fogsettings file if you are doing a clean new install anyway - maybe backup if in case you need it later on.

[Tom Elliott]

@Sebastian-Roth To add an, if you still want to update, but want dynamic packages, just remove the packages line altogether from the .fogsettings file (while maintaining the file itself.)

[kortnor]

@Sebastian-Roth
I tried that also
Cleaning setup

• delete /etc/httpd/conf.d/fog
• rm -rf /var/www/html/fog
• rm -rf /opt/fog/
• fully delete mysql (lke explained before)

restart install

• cd /opt/fogGit/
• git pull
• cd bin
• ./installfog.sh

I don’ think I’m missing something.

[Sebastian Roth]

@kortnor On my system I was not able to fully remove the mariadb/mysql packages because mariadb/mysql-libs is needed by some very important system packages. So I am wondering if you somehow managed to install mysql-libs and are not able to get rid of it anymore? rpm -qa | grep -e mysql -e mariadb (just a wild guess)

[kortnor]

@Tom-Elliott
also, After deleting the whole opt/fog directory I suppose the install script reacts like it will be a new installation ==> so creating the folder again.

Now what I’ve done is:

• yum remove mariadb*
• check 2 time if there is no mysql pkg wih ==> yum list installed | grep mysql

make a new installation again.

Now I arrived to the fog webui

for your info the script has installed the following mysql package
mysql.x86_64 5.5.48-1.el6.remi @remi
mysql-libs.x86_64 5.5.48-1.el6.remi @remi
mysql-server.x86_64 5.5.48-1.el6.remi @remi

now, because mysql is replaced by mariadb , will there be any changed applied to the script when its run to centos 7 or rhel 7 ?

Best,

[Sebastian Roth]

@kortnor Try running the following commands on your system. Here is what they show on my system (as well CentOS 7 fresh install but installs mariadb):

I am wondering why you have mysql el6 packages installed…?!?

@Sebastian-Roth
i’m using the following package

[root@fog ~]# rpm -qa | grep -e mysql -e mariadb
mysql-5.5.48-1.el6.remi.x86_64
mysql-libs-5.5.48-1.el6.remi.x86_64
php-mysqlnd-7.0.4-1.el7.remi.x86_64
mysql-server-5.5.48-1.el6.remi.x86_64

But i can’t use mariadb also and that’s a major threat for me:
everytime I restart my server host, I need to create the /var/run/mysqld /; touch /var/run/mysqld.pid ; chown -R mysql:mysql /var/run/mysqld
otherwise mysql won’t start

[Sebastian Roth]

@kortnor Ahhhh… the “old” mysql package is still newer than the mariadb package (5.5.48 vs 5.5.44). Therefore yum prefers to install the EL6 mysql version instead of using EL7 mariadb.

yum remove remi-release-6
rpm -Uvh  http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y update
yum --enablerepo=remi list mysql

[kortnor]

@Sebastian-Roth
that’s really interresting, I’ll create a fresh new vm ( aside the my running one, ) and try what’s you’re proposing, I should do that for thursday evening

In the meantime, I need to learn how to fine tune the images because at the end I would like to apply it on a cluser created with 6 intel nuc.
On each nuc, I’ll push my images but after every nuc needs to be configurer with a static ip ( for sure different for everyone )

[Tom Elliott]

@kortnor The datetimezone issue should be fixed in the latest update. I wasn’t implicitly defining a Timezone, so it would not find any data in the case of a fresh install.

I found two places that I could use to ensure the timezone is set (albeit not necessarily accurate) in the case the DB hasn’t been loaded yet (fresh install), the php.ini file does not have a date.timezone specified (php defaults to commenting the timezone out). The fix, for now, is test the presence of the variable by means of checking if it’s empty or not.

Mind you if the php.ini file IS set with the date timezone setting, it will NOT try to use the one defined in the DB anyway. However, if you aren’t comfortable messing in /etc/php.ini, the current push of FOG should take over and operate as originally expected (no more 500 heres or erroneous error messages.)
