同理，下面只修改第一行 
[root@localhost Server]# vim /etc/vsftpd/vconf/production 
[root@localhost Server]# vim /etc/vsftpd/vconf/humanr 
[root@localhost Server]# vim /etc/vsftpd/vconf/finance 
[root@localhost Server]# vim /etc/vsftpd/vconf/admin 
[root@localhost Server]# chmod o+wt /ftphome/admin/ 
[root@localhost Server]# chmod o+wt /ftphome/finance/ 
[root@localhost Server]# chmod o+wt /ftphome/humanr/ 
[root@localhost Server]# chmod o+wt /ftphome/production/ 
[root@localhost Server]# chmod o+wt /ftphome/sales/ 
[root@localhost Server]# service vsftpd start 
Starting vsftpd for vsftpd:                                [  OK  ] 
[root@localhost Server]# chkconfig vsftpd on

 

SNMP 代理：

配置yum服务器：

[root@localhost Server]# cat /etc/yum.repos.d/rhel-debuginfo.repo 
[rhel-server] 
name=Red Hat Enterprise Linux server 
baseurl=file:///mnt/cdrom/Server 
enabled=1 
gpgcheck=1 
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

编辑配置文件/etc/snmp/snmpd.conf 。将第62 行的read字段对应的值改为all，表示可以访问所有的mib库；第85行定义“all”对应的mib是哪些；并设置配置沟通密码（团体名）；设置陷阱，将陷阱信息发送至NMS（网络管理工作站）

[root@localhost ~]# vim /etc/snmp/snmpd.conf

62 access notConfigGroup "" any noauth exact all none none

85 view all included .1 80

50 rocommunity public

51 rwcommunity private

79 com2sec mynetwork 192.168.1.193/28 public

保存退出

启动snmp服务，并将snmp服务设置为开机自启动

[root@localhost ~]# service snmpd start 启动服务

Starting snmpd: [ OK ]

[root@localhost ~]# chkconfig snmpd on

查看snmp服务的端口号，有两个端口号：199和169

[root@localhost ~]# netstat -tupln |grep snmp

tcp 0 0 127.0.0.1:199 0.0.0.0:* LISTEN 12052/snmpd

udp 0 0 0.0.0.0:161 0.0.0.0:* 12052/snmpd

日志转发：

编辑系统日志配置文件/etc/syslog.conf，将需要转发的日志发送到指定的日志服务器上。咋日志类型后面加 @日志服务器的地址 即可将日志发送到指定的日志服务器上。

[root@mail ~]# vim /etc/syslog.conf

*.info;mail.none;authpriv.none;cron.none @192.168.1.194

重启日志服务

[root@mail ~]# service syslog restart

Shutting down kernel logger: [ OK ]

Shutting down system logger: [ OK ]

Starting system logger: [ OK ]

Starting kernel logger: [ OK ]
