1、檢查是否安裝了vsftpd
[root@linux01 ~]# rpm -qa|grep vsftpd
2、安裝vsftpd
[root@linux01 ~]# yum -y install vsftpd
3、啟動vsftpd
[root@linux01 ~]# service vsftpd start
4、設置開機啟動
[root@linux01 ~]# chkconfig vsftpd on
5、管理vsftpd相關命令
啟動vsftpd: service vsftpd start
停止vsftpd: service vsftpd stop
重啟vsftpd: service vsftpd restart
狀態vsftpd: service vsftpd status
6.nginx啟動
[root@linux01 conf]# cd /usr/local/nginx-1.8.1/sbin
