1、修改ssh配置
[root@elk-node2 ~]# vim /etc/ssh/sshd_config
大概132行把下面这个句注释掉
#Subsystem sftp /usr/libexec/openssh/sftp-server
添加以下内容
Subsystem sftp /usr/libexec/openssh/sftp-server -l INFO -f local5
LogLevel INFO
2、修改rsyslog配置
[root@elk-node2 ~]# vim /etc/rsyslog.conf
添加以下内容
auth,authpriv.*,local5.* /var/log/sftp.log
3、重启服务
[root@elk-node2 ~]# systemctl restart sshd
[root@elk-node2 ~]# systemctl restart rsyslog
4、用FTP工具连接查看日志
[root@elk-node2 ~]# tail /var/log/sftp.log
