Install ownCloud stable (currently 9.0.2) on CentOS 7

JaredBusch

Based on my original how to Install ownCloud 8.x on CentOS 7

A number of people have been saying that they cannot get ownCloud 9 to install correctly so I decided to give it a go based on a clean CentOS 7 Minimal install. The base OS is still the 1511 release.

Install CentOS 7 and then log in as root. If you choose not to do that, then be prepared to prepend almost every command that follows with sudo.

First things first, you always update to current.

 yum -y update

Now we need to install a few additional packages. It is required to instal wget in order to complete the install of ownCloud per their instructions. I additionally always install nano because I hate vi but it is not required. Finally you need to install a database because the ownCloud documentation itself clearly tells you not to use the built in SQLite database if you are using a desktop sync client. The default database for CentOS is mariadb. Finally the 1511 release of CentOS did not include firewalld in a minimal install for unknown reasons.

yum -y install wget nano mariadb mariadb-server firewalld

SELinux is something a lot of people like to just permanently set to permissive mode. I disagree with disabling security just because it is easy. OwnCloud has specific instructions for SELinux that do not work, but we will fix it correctly. For now, set it to permissive. This will not survive a reboot. If you reboot prior to completing the install you will have to set this again.

setenforce permissive

Start the firewall and enable it to start on boot and then allow http traffic.

systemctl enable firewalld
systemctl start firewalld
firewall-cmd --zone=public --add-port=http/tcp --permanent
firewall-cmd --reload

Start the database and set it to start on reboot

systemctl enable mariadb
systemctl start mariadb

This step is optional, but I never run a database that anyone can access with out a password. Secure the database install

mysql_secure_installation

This will start a wizard to enable typical security measure for the database. The capitalized letter is the default, and is the choice you want to make, so you can simply hit enter through all of these except for setting the new password, obviously.

Enter current password for root (enter for none):
Set root password? [Y/n]
New password: databaserootpassword
Re-enter new password: databaserootpassword
Remove anonymous users? [Y/n]
Disallow root login remotely? [Y/n]
Remove test database and access to it? [Y/n]
Reload privilege tables now? [Y/n]

Sign in to the database and create the ownCloud instance and user.
You will be prompted to enter your database root password.

mysql -uroot -p

Now you will run 4 SQL commands, please note the ; at the end of each. It is a required part of the SQL syntax . These are simplified defaults, I would generally recommend you set them to something a little less obvious just to help with security.

create database ownclouddb;
create user 'ownclouduser'@'localhost' identified by 'ownclouduserpassword'; 
grant all on ownclouddb.* to 'ownclouduser'@'localhost';
flush privileges;
quit

Now, we can finally have the base OS ready for ownCloud. If you are doing this in a location that you can make snapshots, this is a great point to do it.

OwnCloud has setup a "stable" repository that you can use, or you can choose to use a repository for a specific version. We will use the stable repository for this example.

Import the owncloud repository key.

rpm --import https://download.owncloud.org/download/repositories/stable/CentOS_7/repodata/repomd.xml.key

Install the EPEL repository

yum -y install epel-release

Download the ownCloud repository into the yum repos folder and force yum to clean up.

wget http://download.owncloud.org/download/repositories/stable/CentOS_7/ce:stable.repo -O /etc/yum.repos.d/ce:stable.repo
yum clean expire-cache

Finally, we can install ownCloud itself. Beginning with version 9 it has been split into two parts. owncloud-deps and owncloud-files. You can read about why here if you desire.
I install both the owncloud metapackage as well as the owncloud-files just in case they add something to the files but neglect to make sure the metapackage pulls the change correctly.

yum -y install owncloud owncloud-files

But wait, there is more. The ownCloud install does not tell the web server to start on reboot. So do that now.

systemctl enable httpd

With version 8.2 that was it. With version 9.0.2 when I was at this point and tried to load the webpage, I received a connection refused. I shutdown firewalld and made sure SELinux was passive, and still no luck.

So when in doubt reboot.

After rebooting, the webpage came up but told me it could not access the config directory. This is the result of SELinux now being on (because I rebooted).

So time to resolve SELinux

semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/apps(/.*)?'
restorecon -R /var/www/html/owncloud/apps
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/config(/.*)?'
restorecon -R /var/www/html/owncloud/config

Now we are done and we can log into to our instance at

http://X.X.X.X/owncloud

If you did everything correct, you will see this screen, with all the DB config hidden, click the "Storage & database" text to expand it. Create an admin username and password for the GUI and then fill out to the database section match what you used above for the database name, database user, and database user password.

After installing this on a vanilla CentOS install, I added Remi's and updated to PHP 5.6 with no issues either.

Instructions: https://mangolassi.it/topic/8433/adding-remi-s-rpm-repository-to-centos-7-and-updating-to-php-5-6

Dashrender

so it's still not working with PHP 7.x?

You are conflating different issues.

People said they cannot install ownCloud 9.0.X. Here are the instructions.

Performing a repo based install of ownCloud means it is supposed to work with PHP 5.4. It does. It also works fine with PHP 5.6 from Remi.

I've always gotten to that screen. It falls down only after entering the information for the database/storage location/admin login. Did you try to login, and then check that it's using the correct database?

logged in and apparently working, yes.

@JaredBusch Well, what the hell was falling over for me? I'm thinking my problems were mostly caused by RamNode doing non-standard things with their CentOS installs from the looks of things. I'm gonna try building one in VirtualBox just to see.

alex.olynyk

@travisdh1 i did one in VBOX and had the same issue, curious...

travisdh1

@JaredBusch Now this is just odd. Worked just fine on a local VirtualBox VM. Wouldn't work for anything on my ramnode instance. Now I want to know how broken RamNode made their system images!

travisdh1

It appears the testing line of ownCloud will install php7 dependencies even tho the only dependency package looks like php5. Runs much better, and nothing unexpected is happening to me this time. When the stable branch fails, apparently testing could be better!

So Vultr has SELinux disabled by default. I attempted to check how to enable it here. It has you edit /etc/sysconfig/selinux but when I go to it it's empty. I entered all of the information, essentially creating a new document but SELinux is still disabled. I'm guessing this probably isn't accurate?

Why are you trying to enable it? While it is certainly best to have it enabled, by being disabled, there would be no impact on your install.

You said in your guide that you disagree with SELinux being put into permissive mode or disabled. I want everything to be JB best practice

Then you should not start from a system that has it permanently gone.

I wasn't sure if that was the case or not. There is no way for me to enable it? I thought it might just come disabled by default but not permanently.

I have never tried. I do not have any production systems on Vultr. I have only used it for testing FreePBX to date.

You could get around it by not using their default CentOS image and load your own from an uploaded ISO.

That makes sense. Thanks!

Followed the instructions to the letter except for Remi PHP 5.6 (will do next week), and worked flawlessly. Thanks. Quick question. Under Admin File Handling, the default is 513MB. Changing is greyed out with message of "Missing permissions to edit from here." Did quick google and see a few that have that issue and a couple of workarounds that, TBH, confuse. Care to note how to change that?
