简简单单让selinux放过ftp一马，使用户能够上传

废话不多说,先贴出我们强大的man文档：

FILE_CONTEXTS 
       SELinux requires files to have a file type. File types may be specified 
       with  semanage  and  are  restored with restorecon.  Policy governs the 
       access that daemons have to files. 
 
       Allow ftp servers to read the /var/ftp directory  by  adding  the  public_content_t  file  type  to  the  directory and by restoring the file 
       type. 
 
       semanage fcontext -a -t public_content_t "/var/ftp(/.*)?" 
 
       restorecon -R -v /var/ftp 
 
       Allow ftp servers to read and write  /var/tmp/incoming  by  adding  the 
       public_content_rw_t  type  to  the  directory and by restoring the file 
       type.  This also requires the allow_ftpd_anon_write boolean to be  set. 
 
       semanage fcontext -a -t public_content_rw_t "/var/ftp/incoming(/.*)?" 
       /× chcon -Rt public_content_rw_t /var/ftp/ 一样的！！×/
       restorecon -R -v /var/ftp/incoming 
 
 
BOOLEANS 
       SELinux policy is based on least privilege required  and  may  also  be 
       customizable by setting a boolean with setsebool. 
 
       Allow  ftp servers to read and write files with the public_content_rw_t 
       file type. 
 
       setsebool -P allow_ftpd_anon_write on 
 
       Allow  ftp servers to read or write files in the user home directories. 
 
       setsebool -P ftp_home_dir on 
 
       Allow ftp servers to read or write all files on the system. 
 
       setsebool -P allow_ftpd_full_access on 
 
       Allow ftp servers to use cifs for public file transfer services. 
 
       setsebool -P allow_ftpd_use_cifs on 
 
       Allow ftp servers to use nfs for public file transfer services. 
 
       setsebool -P allow_ftpd_use_nfs on 

参考上面的文档,在vsftpd本身配置没有问题的情况下,只需要如下两个命令就搞定ftp上传咯：

root@local# setsebool -P allow_ftpd_anon_write on
 
root@local# chcon -Rt public_content_rw_t /var/ftp/
