Nextcloud Onlyoffice Nodejs and npm version

LayLow · December 25, 2018, 5:48am

@all Happy holiday season.

It seems that NS does not completely meet the requirements for Onlyoffice document server. Onlyoffice Document server requires Nodejs version 8 where NS comes Nodejs version 6 (nodejs-6.14.3-1.el7.x86_64) by default.

This results in too high CPU usage, a massive ammount of worker restarts and very large log files. (see /var/log/onlyoffice/documentserver/spellchecker). Please also see top to identify the processes.

The remidy seems to be to use Nodejs version 8, which is available via Software Collections (rh-nodejs8-nodejs).

Any chance you are willing to take a look at this please?

Reference:
https://dev.onlyoffice.org/viewtopic.php?f=4&t=11632&p=18901&hilit=cpu+usage#p18901

Although not the exact same error, my log huge log files have and endless:

Error: Module version mismatch. Expected 48, got 57.
at Error (native)
at Object.Module._extensions…node (module.js:604:18)

module.js:604
return process.dlopen(module, path._makeLong(filename));
^

Which suggests that there is an issue regarding the Nodejs version used.

Edit: And while we’re at it, it seems the requirements must include an NPM update too according the changelog:

For sure, thanks for testing and sharing.
Actually I couldn’t reproduce it on a fresh installed vm but on an older server. Thanks for the pointers about nodejs, I’ll have a look and report…

LayLow · December 26, 2018, 12:48pm

Meanwhile I wanted to install the scl version of nodejs8 to do some testing. Unfortunately I came across this error:

Transaction check error:
file /usr/lib/rpm/nodejs_native.req from install of rh-nodejs8-nodejs-8.11.4-1.el7.x86_64 conflicts with file from package nodejs-1:6.14.3-1.el7.x86_64

I could use --force, but I do not want to mess up the RPM db and logic.

mrmarkuz · December 26, 2018, 12:59pm

The original onlyoffice-documentserver rpm requires the nodejs package from epel which conflicts with rh-nodejs8.

Here it seems nodejs 6.9 is required and 6.14 is provided by epel:

LayLow · December 26, 2018, 1:01pm

Yes, nodejs 6.9 is listed, but that document is over 2 years old

LayLow · December 26, 2018, 1:02pm

Is this solvable?

mrmarkuz · December 26, 2018, 1:03pm

If it’s really a nodejs version problem it should be posted at the onlyoffice side so they could change their package.
I am going to check if it’s solvable without changing nodejs…

EDIT:

You may add the nodejs repo

curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -

https://helpcenter.onlyoffice.com/server/linux/document/linux-installation-centos.aspx

EDIT2:

For me it’s working now without high CPU load of the node process…

LayLow · December 26, 2018, 1:35pm

Also interesting, the SCL version of Nodejs version 8 is Nodejs 8.11:
Installing:
rh-nodejs8 x86_64 3.0-3.el7 centos-sclo-rh 6.6 k
Installing for dependencies:
rh-nodejs8-nodejs x86_64 8.11.4-1.el7 centos-sclo-rh 7.1 M
rh-nodejs8-npm x86_64 5.6.0-8.11.4.1.el7 centos-sclo-rh 4.4 M
rh-nodejs8-runtime x86_64 3.0-3.el7 centos-sclo-rh 1.1 M

Whilse the minimum version required by Onlyoffice is version 8.12 (and I believe that is a LTS version)

So using nodejs from SCL is not a an option

mrmarkuz · December 26, 2018, 1:36pm

Please try this, it works for me without high CPU load:

curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -
yum install nodejs

LayLow · December 26, 2018, 1:38pm

Result:

[root@srv01 ~]# curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -

Installing the NodeSource Node.js 8.x LTS Carbon repo…

Inspecting system…

rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release
uname -m

Confirming “el7-x86_64” is supported…

curl -sLf -o /dev/null ‘https://rpm.nodesource.com/pub_8.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm’

Downloading release setup RPM…

mktemp
curl -sL -o ‘/tmp/tmp.dsWo2XM5lh’ ‘https://rpm.nodesource.com/pub_8.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm’

Installing release setup RPM…

rpm -i --nosignature --force ‘/tmp/tmp.dsWo2XM5lh’

Cleaning up…

rm -f ‘/tmp/tmp.dsWo2XM5lh’

Checking for existing installations…

rpm -qa ‘node|npm’ | grep -v nodesource

Your system appears to already have Node.js installed from an alternative source.

Run sudo yum remove -y nodejs npm to remove these first.

Run `sudo yum install -y nodejs` to install Node.js 8.x LTS Carbon and npm.

You may also need development tools to build native addons:

 sudo yum install gcc-c++ make

To install the Yarn package manager, run:

 curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
 sudo yum install yarn

mrmarkuz · December 26, 2018, 1:40pm

These are instructions howto use the script, you may just run

yum install nodejs.

If it does not work remove nodejs first with yum remove nodejs.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

mrmarkuz · December 26, 2018, 1:43pm

You have to do

yum remove nodejs

first. I am afraid it will remove documentserver too…you have to reinstall.

LayLow · December 26, 2018, 1:46pm

Yup, was trying to avoid that…

Actually doing the same procedure on another server…

I’ll leave you to it for now. Let it sink in

Thanks!

mrmarkuz · December 26, 2018, 3:26pm

For me it works with nodejs 8 without high CPU load. Thanks for pointing that out.

I updated the module and the wiki entry to support installation of nodejs 8:

giacomo · December 27, 2018, 10:08am

If you still have an high load, just disable the systemd unit which spawn the dictionary module
I’ve already done it on a test machine, but I don’t remember the unit name.

LayLow · December 27, 2018, 11:22am

I can confirm. CPU load dropped drastically and no more nodejs errors in the log files. And as a bonus, the spellchecker is now functional

Many thanks.
