3.使用rpm-IVH VSFTPD-2 . 2 . 2-11 . el6 _ 3.1 . src . rpm安装软件包：
[root@localhostbirdofprey]#rpm-ivhvsftpd-2.2.2-11.el6_3.1.src.rpm
在安装过程中，系统会提示类似如下的错误：
warning:vsftpd-2.2.2-11.el6_3.1.src.rpm:HeaderV3RSA/SHA1Signature,keyIDc105b9de:NOKEY

此时，您需要使用adduser mockbuild命令来创建一个mockbuild用户：
[root@localhostbirdofprey]#addusermockbuild
4.重复使用rpm-IVH VSFTPD-2 . 2 . 2-11 . el6 _ 3.1 . src . rpm来安装软件包：
[root@localhostbirdofprey]#rpm-ivhvsftpd-2.2.2-11.el6_3.1.src.rpm
warning:vsftpd-2.2.2-11.el6_3.1.src.rpm:HeaderV3RSA/SHA1Signature,keyIDc105b9de:NOKEY

5、使用命令CD/root/rpmbuild/SOURCES/vsftpd/SOURCES进入vsftpd源码包目录，
And use tal-zxvf vsftpd-2.2.2.tar.gz to decompress the vsftpd-2.2.2.tar.gz source package:
[root@localhostSOURCES]#tar-zxvfvsftpd-2.2.2.tar.gz
6.使用命令cd vsftdp-2.2.2进入vsfftpd-2.2.2的源目录：
[root@localhostSOURCES]#cdvsftpd-2.2.2
7. Use the command 6. Feature modification function. C file; The line content is: vsf_cmdio_write_raw(p_sess,' utf8 \ r \ n');
修改为：//vsf_cmdio_write_raw(p_sess，' UTF8\r\n ')。
8.使用命令vi opts.c修改opts.c文件；
修改handle_opts函数，如下所示：
void
handle_opts(structvsf_session*p_sess)
{
str_upper(p_sess-ftp_arg_str);
//if(str_equal_text(p_sess-ftp_arg_str,'UTF8ON'))
//{
//vsf_cmdio_write(p_sess,FTP_OPTSOK,'AlwaysinUTF8mode.');
//}
//else
//{
//vsf_cmdio_write(p_sess,FTP_BADOPTS,'Optionnotunderstood.');
//}
}
9.返回到上层目录，用tar-zcvf vsftpd-2.2.2.tar.gz vsftpd-2 . 2 . 2/command重新压缩vsftpd-2.2.2.tar.gz文件：
[root@localhostSOURCES]#tar-zcvfvsftpd-2.2.2.tar.gzvsftpd-2.2.2/
我们可以使用ls-命令查看列表中vsftpd-2.2.2.tar.gz文件的创建时间已经是当前的创建时间，如下所示：
-rw-rw-r。 1 Simulation Construction Simulation Construction 186982 May 3 15: 39 VSFTPD-2.2.2.tar.gz-RW-R-R-. 1 simulation construction simulation construction 2828 February 13 00: 06 vsftpd-2.2.2-uint-uigid.patch-rw-r-r-. 1 simulation build simulation build 1640 February 13 00:06 vsftpd-2. 2. 2- V6. patch-rw-r-r- only. 1 simulation construction simulation construction 514 February 13 00: 06 vsftpd-close-STD-FDS. patch-rwxr-xr-x.1 mock build mock build 338 February 13 00: 06 vsftpd _ conf _ migrate.sh-rw-r-. 1 simulation build simulation build 125 February 13 00: 06 vsftpd.ftpusers-rwxr-xr-x.1 mock build 2824 February 13 00:06 vsftpd.init-rw-r-r-. 1 simulation construction simulation construction 335 February 13 00:06 vsftpd.pam-rw-r-r-. 1 simulation build simulation build 361 February 13 00: 06 vsftpd. user _ list-rw-r-r-. 1 simulation build simulation build 345 February 13 00:06 vsftpd.xinetd10, enter the specification directory under the source package,
[root@localhostSPECS]#rpmbuild-bbvsftpd.spec
此时，将会报告以下错误，因为系统缺少依赖包：
