Centos5.664-bit compilation installation vsftpd-2.3.4 and configuration

Centos5.6 (64bit) compiler installation vsftpd-2.3.4 configuration (two types of user login) Virtual User login is more secure than local user login. Because a vsftpd virtual user is not a system account, it is only used to support the Vsftpd service. Therefore, it is not necessary to allow him to log on to the system, this is more secure than setting the logon account of a local user as the logon system. I. key points of the article:
Virtual User configuration using PAM data in a 1.64-bit system
2. the key script is successfully compiled. Necessary steps: detailed installation and configuration instructions.
3. full configuration instance, Centos5.6 build and install vsftpd-2.3.4 (configure local user login, Virtual User login)
Download
Wget http://xiazai.xiazaiba.com/Soft/V/vsftpd-2.3.4.tar.gz
Tar xzvf vsftpd-2.3.4.tar.gz
Cd vsftpd-2.3.4
Key steps: Because the SO file path of the 64-bit system changes, you must change the vsf_findlibs.sh script to change lib to lib64.
It can be manually modified or modified in batches.
Sed-I's/lib \ // lib64 \ // g' vsf_findlibs.sh will not be executed here. in a 64-bit system, make will fail.

II. detailed installation and configuration instructions:1. first install PAMyum install pam-devel db4-utils2, install vsftpdyum install vsftpd *
3. check whether pamldd/usr/sbin/vsftpd is loaded in vsftpd. if ibpam is displayed in the output. so.0 =>/lib/libpam.so.0, success 4. Generate user verification data warehouse file 1)create loguser.txt in the following format (user, password, user, password .....) userid
Pass2) after saving, use db_load-T-t hash-f loguser.txt/etc/vsftpd/vsftpd_login.db, check whether the files in this directory generate the access permission chmod 600/etc/vsftpd_login.db5, vim/etc/pam. d/vsftpd add the following line in the header auth required/lib/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login
Account required/lib/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login note: If it is a 64-bit operating system, the path here should be changed to auth required/lib64/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login
Account required/lib64/security/pam_userdb.so db =/etc/vsftpd/vsftpd_login. otherwise, after vsftpd is started, Error 530 will be reported. this error, previously, similar instruction files on other websites did not indicate this issue. comment out other content. 6. vim/etc/vsftpd. conf to ensure that the following settings are included: anonymous_enable = NO
Local_enable = YES
Write_enable = NO
Anon_upload_enable = NO
Anon_mkdir_write_enable = NO
Anon_other_write_enable = NO
Chroot_local_user = YES
Guest_enable = YES
Guest_username = virtual // --- local user mapped here
Listen = YES
Listen_port = 21
Pasv_min_port = 30000
Pasv_max_port = 309997, start vsftpd 3. fully configure the instance
