Rsync - Setting up a basic rsyncd server on EL8

Rsync is a very easy way to transfer large amounts of files between servers with low resource usage which also makes for a great backup target due to its speed and flexibility. Here's a small write-up on how to set up a basic rsyncd server:

First, install the required packages:

 [archy@mirror01~]$ sudo yum -y --refresh install rsync rsync-daemon  

Create the rsync root directory, I'll place all my sub-modules (folders) in '/var/rsync'

 [archy@mirror01 ~]$ mkdir -p /var/rsync/{rpms,backup}  

Setting the SELinux boolean and file context:

 [archy@mirror01 ~]$ sudo semanage boolean -m -1 rsync_full_access  
 [archy@mirror01 ~]$ sudo semanage fcontext -a -t 'public_content_t' '/var/rsync(/.*)?'  
 [archy@mirror01 ~]$ sudo restorecon -Rv /var/rsync  

Creating /etc/rsyncd.conf:

 [archy@mirror01 ~]$ sudo vim /etc/rsyncd.conf  

 pid file = /var/run/rsyncd.pid  
 log file = /var/log/rsyncd.log  
 lock file = /var/run/rsyncd.lock  
 address = 0.0.0.0  
 port = 873  
 [rpms]  
   comment = share for rpms  
   path = /var/rsync/rpms  
   read_only = false  
   write_only= false  
   timeout = 300  
 [backup]  
   comment = backup share  
   path = /var/rsync/backup  
   read only = false   
   write only = true  
   timeout = 300  

Restart enable and restart the rsyncd service:

 [archy@mirror01 ~]$ sudo systemctl enable rsyncd.service  
 [archy@mirror01 ~]$ sudo systemctl restart rsyncd.service  

Keep in mind that this is a very basic setup for shares using rsync. For more options, see rsyncd.conf(5).
