ftp的yum的搭建步骤
第一步：安装vsftpd程序包（系统已经安装）
[root@station40 ~]# rpm -qa |grep vsftpd
vsftpd-2.2.2-21.el6.x86_64
第二步：安装完成后需要启动他例：
先找打vsftpd中的文件中有 vsftpd.service结尾的文件然后启动这个文件服务例;
systemctl start vsftpd.service （CentOS7使用这个）
service vsftpd start （CentOS6使用这个）
注：因为我的文件中未找到该文件所以我使用的是下面这个启动命令：
[root@station40 ~]# service vsftpd start
[root@station40 ~]#
第三步：因为刚才的启动为实时启动，关机后就不再启动所以还需要将其改成开机启动，但是我尚明的那条命令就是开机启动，正常的开机启动使用下面的这条命令：
[root@station40 ~]# systemctl enable vsftpd.service （CentOS7使用这个）
chkconfig vsftpd on （CentOS6使用这个）
第四步：找到该程序的目录文件例：
[root@station40 ~]# rpm -ql vsftpd |tail
/usr/share/doc/vsftpd-2.2.2/SECURITY/TRUST
/usr/share/doc/vsftpd-2.2.2/SIZE
/usr/share/doc/vsftpd-2.2.2/SPEED
/usr/share/doc/vsftpd-2.2.2/TODO
/usr/share/doc/vsftpd-2.2.2/TUNING
/usr/share/doc/vsftpd-2.2.2/vsftpd.xinetd
/usr/share/man/man5/vsftpd.conf.5.gz
/usr/share/man/man8/vsftpd.8.gz
/var/ftp
/var/ftp/pub
注：红色标注就是ftp默认的共享目录。该目录就是日后第三方的软件放置目录，很明显该目录是个空目录没有任何文件的
例：
第五步：现在可以尝试将光盘的程序包复制到该目录下现在可以将tree这个文件复制到 /var/ftp/pub里面
例：
注：可以看出目前的目录下有了tree这个文件
第六步：现在需要确认防火墙有没有关掉，没有则需要将其关掉
[root@station40 ~]# chkconfig

wpa_supplicant 0:off 1:off 2:off 3:off 4:off 5:off 6:off
可以看出防火墙是打开状态，所以现在需要将他关掉
例：
[root@station40 ~]# iptables -F (CentOS7使用这个）
[root@station40 ~]# chkconfig iptable off (CentOS6使用这个）
NetworkManager 0:off 1:off 2:on 3:on 4:on 5:on 6:off
auditd 0:off 1:off 2:on 3:on 4:on 5:on 6:off

vsftpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
winbind 0:off 1:off 2:off 3:off 4:off 5:off 6:off
wpa_supplicant 0:off 1:off 2:off 3:off 4:off 5:off 6:off
可以看出防火墙关掉了
第七步：现在再次确认ftp的服务端口是否打开
例：[root@station40 ftp]# netstat -ntl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:6011 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
tcp 0 0 ::1:25 :::* LISTEN
tcp 0 0 ::1:6010 :::* LISTEN
tcp 0 0 ::1:6011 :::* LISTEN
可以看出ftp的21号端口没有打开。所以需要打开
例：[root@station40 ftp]# service vsftpd start （实时启动vsftpd 服务）
Starting vsftpd for vsftpd: [ OK ] （显示vsftpd服务启动ok）
[root@station40 ftp]# netstat -ntl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:6011 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
tcp 0 0 ::1:25 :::* LISTEN
tcp 0 0 ::1:6010 :::* LISTEN
tcp 0 0 ::1:6011 :::* LISTEN
先在我们在pub目录下在创建一个app目录用来放置第三方的程序例：
[root@station40 pub]# mkdir app
[root@station40 pub]# ls
app tree-1.6.0-10.el7.x86_64.rpm
[root@station40 pub]# mv tree-1.6.0-10.el7.x86_64.rpm app
[root@station40 pub]# ls
app
第八步：需要生成repodata元数据，就要用到一个命令工具createrepo，如果系统上没有则需要使用yum去安装。
例：
[root@station40 ~]# yum install createrepo
Loaded plugins: fastestmirror, refresh-packagekit

Complete!
安装ok后接下来我们就可以生成repodata源数据：
例：
[root@station40 ~]# createrepo /var/ftp/pub/app/ （这里是给清楚路径）
Spawning worker 0 with 1 pkgs
Workers Finished
Gathering worker results
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
生成ok后我们可以检查app目录下是否生成repodata的程序包：
例;
[root@station40 pub]# ls app
repodata tree-1.6.0-10.el7.x86_64.rpm
[root@station40 repodata]# ls
