[syslog-ng] Why Syslog-NG can't start?

[Jason Long]

Hello.
I installed Syslog-NG on CentOS 7 x64 and my configuration is :



@version:3.5
@include "scl.conf"

# syslog-ng configuration file.
#
# This should behave pretty much like the original syslog on RedHat. But
# it could be configured a lot smarter.
#
# See syslog-ng(8) and syslog-ng.conf(5) for more information.
#
# Note: it also sources additional configuration files (*.conf)
#       located in /etc/syslog-ng/conf.d/

options {
flush_lines (0);
time_reopen (10);
log_fifo_size (1000);
long_hostnames (off);
use_dns (no);
use_fqdn (no);
create_dirs (no);
keep_hostname (yes);
ts_format(iso);
encoding(UTF-8);
};

source s_netsyslog {
udp(ip(0.0.0.0) port(514) flags(no-hostname));
tcp(ip(0.0.0.0) port(514) flags(no-hostname));
};

destination d_netsyslog { file("/var/log/network.log" owner("root") group("root") perm(0644)); };
destination d_separatedbyhosts{file("/var/log/$HOST/messages" owner("root") group("root") perm(0655) dir_perm(0755) create_dirs(yes));
};


log { source(s_netsyslog); destination(d_separatedbyhosts); };

# Source additional configuration files (.conf extension only)
@include "/etc/syslog-ng/conf.d/*.conf"


# vim:ft=syslog-ng:ai:si:ts=4:sw=4:et:





But my Syslog-NG can't start and give me below error:

# systemctl status syslog-ng.service

How can I solve it?

Thank you.
