yum-plugin-needs-restarting

yum-plugin-needs-restarting is a YUM plugin for listing processes using old files after upgrading your system. It is based on the code of needs-restarting which is part of the yum-utils package.

I decided to create a YUM plugin for this purpose because I really missed something like zypper ps (openSUSE, SUSE Linux Enterprise Server/Desktop) on Fedora and Enterprise Linux (Red Hat Enterprise Linux, CentOS, ScientificLinux,...)

Features

The plugin checks for processes which are part of installed RPM packages and use deleted files. It is also possible to blacklist particular processes by specifying wildcards. The plugin implements a new YUM command: needs-restarting.

Examples

System having no processes using old files:

# yum needs-restarting
Loaded plugins: needs-restarting
This system is receiving updates from RHN Classic or Red Hat Satellite.
You blacklisted:


No processes using old files, nice job.

System running some services using old files:

# yum needs-restarting
Loaded plugins: needs-restarting
You blacklisted:


You might want to restart the following processes:
httpd
sshd

System running processes having no init script using old files:

# yum needs-restarting
Loaded plugins: needs-restarting
You blacklisted:


You might want to restart the following processes:
? (PID 30799, unicorn worker[0] -D -E production -c /var/opt/gitlab/gitlab-rails/etc/unicorn.rb /opt/gitlab/embedded/service/gitlab-rails/config.ru)
? (PID 10053, unicorn worker[1] -D -E production -c /var/opt/gitlab/gitlab-rails/etc/unicorn.rb /opt/gitlab/embedded/service/gitlab-rails/config.ru)
? (PID 28486, unicorn master -D -E production -c /var/opt/gitlab/gitlab-rails/etc/unicorn.rb /opt/gitlab/embedded/service/gitlab-rails/config.ru)
? (PID 28650, nginx: worker process)
? (PID 28649, nginx: worker process)
? (PID 28648, nginx: master process /opt/gitlab/embedded/sbin/nginx -p /var/opt/gitlab/nginx)
? (PID 28584, sidekiq 2.17.0 gitlab-rails [0 of 25 busy])

Example configuration blacklisting various GitLab and nginx processes:

$ cat /etc/yum/pluginconf.d/needs-restarting.conf
[main]
enabled=1
excludeProcs=gitlab,nginx
