Install Proftpd from source in CentOS.

What I Did

I'm trying to install Proftpd from source on CentOS but I don't know where is the problem. I used below commands

wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.6.tar.gz
  tar -zxvf proftpd-1.3.6.tar.gz
  cd proftpd-1.3.6
  ./configure
  make
  make install

whereis proftpd
proftpd: /usr/local/sbin/proftpd /usr/local/etc/proftpd.conf /usr/local/lib/proftpd

vim /usr/lib/systemd/system/proftpd.service

[Unit]
Description = ProFTPD FTP Server
After = network.target nss-lookup.target local-fs.target remote-fs.target

[Service]
Type = forking
PIDFile = /run/proftpd/proftpd.pid
Environment = PROFTPD_OPTIONS=
EnvironmentFile = -/etc/sysconfig/proftpd
ExecStart = /usr/local/sbin/proftpd $PROFTPD_OPTIONS
ExecReload = /bin/kill -HUP $MAINPID

[Install]
WantedBy = multi-user.target

After when I sterted proftpd.service I receive first error fatal: Group: Unknown group 'nogroup' on line 30 of '/usr/local/etc/proftpd.conf, When I changed line 30 from nogroup to nobody next I received second error /run/proftpd/proftpd.pid (yet?) after start: No such file or directory then I created path /run/proftpd/ but an issue still exist. By the way I diabled selinux.

What does your proftpd.conf look like?

[Aldi1990]

My proftpd.conf looks like below

# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

ServerName                      "ProFTPD Default Installation"
ServerType                      standalone
DefaultServer                   on

# Port 21 is the standard FTP port.
Port                            21

# Don't use IPv6 support by default.
UseIPv6                         off

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask                           022

# To prevent DoS attacks, set the maximum number of child processes
# to 30.  If you need to allow more than 30 concurrent connections
# at once, simply increase this value.  Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).
MaxInstances                    30

# Set the user and group under which the server will run.
User                            nobody
Group                           nobody

# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
#DefaultRoot ~

# Normally, we want files to be overwriteable.
AllowOverwrite          on

# Bar use of SITE CHMOD by default
<Limit SITE_CHMOD>
  DenyAll
</Limit>

# A basic anonymous configuration, no upload directories.  If you do not
# want anonymous users, simply delete this entire <Anonymous> section.
<Anonymous ~ftp>
  User                          ftp
  Group                         ftp

  UserAlias                     anonymous ftp

  # Limit the maximum number of anonymous logins

  # We want 'welcome.msg' displayed at login, and '.message' displayed
  # in each newly chdired directory.
