查看配置文件

[root@localhost ~]# cat /etc/syslog-ng/syslog-ng.conf
@version:3.21
@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.
...

防止syslog与syslog-ng冲突，关闭syslog服务：

[root@localhost ~]# chkconfig rsyslog off; chkconfig syslog-ng on
Note: Forwarding request to 'systemctl disable rsyslog.service'.
Removed symlink /etc/systemd/system/multi-user.target.wants/rsyslog.service.
Note: Forwarding request to 'systemctl enable syslog-ng.service'.

停止syslog服务，启用syslog-ng服务：

[root@localhost ~]# service rsyslog stop;service syslog-ng start
Redirecting to /bin/systemctl stop  rsyslog.service
Redirecting to /bin/systemctl start  syslog-ng.service

重启加载配置文件：

[root@localhost ~]# systemctl reload syslog-ng.service

配置文件修改：

@version:3.21
@include "scl.conf"options {time-reap(30);mark-freq(10);keep-hostname(yes);};
source s_local { system(); internal(); };
source s_network {syslog(transport(udp) port(514));}; #syslog使用的协议以及端口
destination d_local {file("/var/log/syslog-ng/messages_${HOST}"); }; #syslog日志保存的位置，以IP命名。#destination d_logs {
#    file(
#        "/var/log/syslog-ng/logs.txt" #syslog日志保存位置
#        owner("root") # 文件所有者
#        group("root") # 文件所属用户组
#        perm(0777)); # 文件权限
#    };log { source(s_local); source(s_network); destination(d_logs);};@include "/etc/syslog-ng/conf.d/*.conf"

发送日志方：syslog 配置修改/etc/rsyslog.conf
