Linux service命令
一堆人都没有回答到关键，码安提示未被识别的码安命令，所谓命令，码安当然是码安-27/32源码指service未被识别了。楼主看看是码安不是启动vsftp时,service拼写错误？
vsftpd这个服务名在最新版也没有变过。
建议如下：
一、码安在/etc/init.d/目录看看能不能找到vsftpd
find /etc/init.d|grep vsftpd
二、码安使用/etc/init.d/vsftpd start看是码安否可以启动
三、vsftpd是码安编译的，有没有在编译之前，码安系统自带有vsftpd，码安荣耀立方 源码如果有，码安那么编译时指定单独路径，码安并且在编译后的码安路径下去启动vsftpd，也可以把启动加入到系统服务。码安
虚拟机Linux系统解压vsftp.tar.gz后怎么手动安装
这个嘛，flash源码梅花简单说下。如果是生产使用。去官网或者centos git下载release版本。非root用户安装，--prefix=/usr/local/vsftpd-x-y-x 安装目录大概选择这个. 当然也可以参照deb build。法国网站源码
参照centos sftpd spec文件，看看里面的编译选项，都打开了哪些？如果直接configure很可能出现各种隐藏的系统配置和漏洞问题。如有需要，对源码进行改修修正。蹦蹦网源码
make之后做测试。make test。
配置项测试。
VSFTPD服务器配置问题
方法一：登录出现 vsftpd login incorrect 报错。
解决方法：
cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp
path为vsftp解压缩源文件目录
这是因为我们RHEL启用了PAM,所在用到vsftp时需要用到 /etc/pam.d/ftp这个文件（默认源码安装的不会有这个文件），因此除了匿名用户外本地用户无法登录。
方法二：
在测试Checkpoint的***1 R6x的时候，遇到了这个错误。这说明client端跟server端的连接性是没问题。但是就是想不出为什么，还以为是用户名和口令错误呢。后来才google了一下，发现是server端的配置有问题。
检查/etc/vsftpd/user_list和/etc/ftpusers，是这个文件/etc/vsftpd/vsftpd.conf少了一行：
复制代码
代码如下:
pam_service_name=vsftpd
$ echo ‘pam_service_name=vsftpd’ /etc/vsftpd/vsftpd.conf
$ service vsftpd restart
error就消除了！
下面是更详细的方法：

# The default compiled in settings are fairly paranoid. This sample file

# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
