Install rsync 3.1.1 on systemd

  • 772

I have CentOS 7 and it comes with Rsync 3.0.9. I downloaded the 3.1.1 el7 rpm and installed with rpm -Uvh.

Now the daemon refuse to start. I tried to create :

/usr/lib/systemd/system/rsyncd.service

[Unit]
Description=A program for synchronizing files over a network
After=syslog.target network.target
ConditionPathExists=/etc/rsyncd.conf

[Service]
EnvironmentFile=-/etc/sysconfig/rsyncd
ExecStart=/usr/bin/rsync --daemon --no-detach "$OPTIONS"

[Install]
WantedBy=multi-user.target

No luck :

/bin/systemctl status  rsyncd.service
● rsyncd.service
   Loaded: not-found (Reason: No such file or directory)
   Active: failed (Result: exit-code) since Thu 2016-04-21 15:27:00 EDT; 56min ago
 Main PID: 1452 (code=exited, status=20)

Note those referenced file in the configuration exist:

-rw-r--r-- 1 root root 1699 Feb  4 14:27 /etc/rsyncd.conf
-rw-r--r-- 1 root root 11 Apr 21 16:09 /etc/sysconfig/rsyncd

  1. I've got 3.1.1 under fedora 22.

    The requisite config files for rsyncd are in the rsync-daemon package. I've listed the files in each package below.

    I'd just install the extra package.

    But, I did notice a typo in your config file ...

    Change:

    EnvironmentFile=-/etc/sysconfig/rsyncd

    Into:

    EnvironmentFile=/etc/sysconfig/rsyncd

    Here's a list of files in the rsync package:

    /usr/bin/rsync
/usr/share/doc/rsync
/usr/share/doc/rsync/NEWS
/usr/share/doc/rsync/OLDNEWS
/usr/share/doc/rsync/README

/usr/share/doc/rsync/tech_report.tex
/usr/share/licenses/rsync
/usr/share/licenses/rsync/COPYING
/usr/share/man/man1/rsync.1.gz

    Here's a list of files in the rsync-daemon package:

    /etc/rsyncd.conf
/etc/sysconfig/rsyncd
/usr/lib/systemd/system/rsyncd.service
/usr/lib/systemd/system/rsyncd.socket
/usr/lib/systemd/system/[email protected]
/usr/share/man/man5/rsyncd.conf.5.gz

    UPDATE:

    I tried to force install rsync-daemon on my Centos 7, given that it's just text file, I took a chance and ignored the dependency.

    I'm not sure what dependency you mean, but I looked at the rpm's .spec file and it lists systemd-units, but I can't find an rpm for that.

    No luck.

    Not quite sure what this means. Did the files extract/install or not? Can you do ls -l on them? As a last resort, did you try rpm --nodeps --force?

    Given an .rpm file, it is possible to manually extract files using rpm2cpio [should be part of the already installed rpm package] and either cpio or pax [which is very similar to tar, but understands both tar and cpio format archives].

    I've usually had better luck using pax. It has its own rpm [to install: yum install pax]. In fact, I've never gotten the rpm2cpio/cpio combination to work correctly for extraction.

    To list an rpm file using pax:

    rpm2cpio rpmfile | pax -v

    To extract an rpm file using pax:

    rpm2cpio rpmfile | pax -v -r

    I also tried to extract the file directly, but it still refuses to start.

    You may have to consult some logfiles, such as /var/log/messages, /var/log/audit/audit.log, /var/log/secure, and may have to use the journalctl program to view the systemd log.

    You might have some [silly] selinux security restriction that has to be fixed. You may have to run restorecon on the config files.

    Also, you may have to add something to the /etc files as it may be rsync itself that doesn't want to start (vs. systemd not starting rsync).

    Below are the contents of the rsync-daemon files, except for the man page file [which is way too large to include here]. The man page file can be found here: http://linux.die.net/man/5/rsyncd.conf

    /etc/rsyncd.conf

    # /etc/rsyncd: configuration file for rsync daemon mode

# See rsyncd.conf man page for more options.

# configuration example:

# uid = nobody
# gid = nobody
# use chroot = yes
# max connections = 4
# pid file = /var/run/rsyncd.pid
# exclude = lost+found/
# transfer logging = yes
# timeout = 900
# ignore nonreadable = yes
# dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2

# [ftp]
#        path = /home/ftp
#        comment = ftp export area

    I found out that systemctl daemon-reload is required to load the service. After doing that, it worked right away.
