需要准备:
1.安装虚拟机,系统Linux CentOS6.4
2.Nginx
3.Vsftpd
1.安装虚拟机
VMware Workstation ,系统Linux CentOS6.4用64位
2.安装nginx
1.使用yum形式安装,搜索CentOS6 yum nginx
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
yum -y install nginx
2.由于Nginx需要依赖其他地方库,在命令行输入:
yum install gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel openssl openssl-devel –y
3.查看nginx安装版本
nginx -v
4.查看nginx安装的信息,如下图所示:
nginx -V
5.修改nginx的配置文件:
vim /etc/nginx/nginx.conf
打开子配置信息,配置ftpuser服务路径:
6.启动、关闭、重启服务:
service nginx start
测试:打开火狐:localhost
service nginx stop
service nginx restart
3安装ftp服务(客户端安装FileZilla Client)
1.安装服务yum -y install vsftpd
2.添加一个ftp用户,此用户就是用来登录ftp服务器用的。
useradd ftpuser
登录后默认的路径为 /home/ftpuser.
3.给ftp用户添加密码
passwd ftpuser
输入两次密码后修改密码。
4.防火墙开启21端口,因为ftp默认的端口为21,而centos默认是没有开启的,所以要修改iptables文件
vim /etc/sysconfig/iptables
在行上面有22 -j ACCEPT 下面另起一行输入跟那行差不多的,只是把22换成21,然后:wq保存。
还要运行下,重启iptables。service iptables restart
5.修改selinux(外网是可以访问上去了,可是发现没法返回目录(使用ftp的主动模式,被动模式还是无法访问),也上传不了,因为selinux作怪了。)
修改selinux:
执行以下命令查看状态:
[root@bogon ~]# getsebool -a | grep ftp
allow_ftpd_anon_write --> off
allow_ftpd_full_access --> off
allow_ftpd_use_cifs --> off
allow_ftpd_use_nfs --> off
ftp_home_dir --> off
ftpd_connect_db --> off
ftpd_use_passive_mode --> off
httpd_enable_ftp_server --> off
tftp_anon_write --> off
[root@bogon ~]#
执行上面命令,再返回的结果看到两行都是off,代表,没有开启外网的访问
[root@bogon ~]# setsebool -P allow_ftpd_full_access on
[root@bogon ~]# setsebool -P ftp_home_dir on
这样应该没问题了(如果,还是不行,看看是不是用了ftp客户端工具用了passive模式访问了,如提示Entering Passive mode,就代表是passive模式,默认是不行的,因为ftp passive模式被iptables挡住了,下面会讲怎么开启,如果懒得开的话,就看看你客户端ftp是否有port模式的选项,或者把passive模式的选项去掉。如果客户端还是不行,看看客户端上的主机的电脑是否开了防火墙,关吧)
FileZilla的主动、被动模式修改:
菜单:编辑→设置
6.启动服务:service vsftpd restart
