vsftpd+pam+mysql服务器的实现_MySQL
一、vsftpd服务器端的安装:
yum install vsftpd
查看安装后生成的哪些文件
[root@station113 ~]# rpm -ql vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd《==================认证文件
/etc/rc.d/init.d/vsftpd《=============服务脚本
/etc/vsftpd《=========================程序的配置文件
/etc/vsftpd/ftpusers《=========
/etc/vsftpd/user_list《==================控制用户访问的
/etc/vsftpd/vsftpd.conf《================主配置文件
/etc/vsftpd/vsftpd_conf_migrate.sh
/var/ftp《===============================服务器文件存放目录
/var/ftp/pub《===========================服务器上共享文件的存放位置
启动服务
[root@station113 ~]# service vsftpd start
Starting vsftpd for vsftpd: [ OK ]
查看启动装态
[root@station113 ~]# ps aux | grep vsftpd
root 5200 0.0 0.0 52524 788 ? Ss 22:55 0:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf
root 5207 0.0 0.0 103252 836 pts/0 S+ 22:56 0:00 grep vsftpd
[root@station113 ~]# ss -tnl《======查看一下21号端口是否启用起来了
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::111 :::*
LISTEN 0 128 *:111 *:*
LISTEN 0 32 *:21 *:*
LISTEN 0 128 :::22 :::*
LISTEN 0 128 *:22 *:*
LISTEN 0
二、服务器端配置
[root@localhost ~]# vim /etc/vsftpd/vsftpd.conf
anonymous_enable=YES《====启用匿名用户
local_enable=YES《=========充许本地用户访问
write_enable=YES《=========是否允许上传文件
anon_upload_enable=YES《====匿名用启上传
anon_mkdir_write_enable=YES《=匿名用户创建目录
anon_other_write_enable=YES《==匿名用户有写权限
定义欢迎信息
banner_file=/path/to/some_banner_file
ftp_banner=some string
dirmessage_enable=yes
在某ftp可访问的目录下创建.messages文件
# You may fully customise the login banner string:
#ftpd_banner=Welcome to blah FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
vsftp控制登录用户的机制:
/etc/vsftpd/ftpusers中的用户都不允许使用ftp服务, 这是在/etc/pam.d/vsftpd中定义;
user_list配置文件有两种用法:
黑名单:
userlist_enable=YES
userlist_deny=YES
白名单
userlist_enable=YES
userlist_deny=NO
写在下面的目录中的用户都不允许登陆
[root@station113 ~]# cd /etc/vsftpd/
[root@station113 vsftpd]# ls
chroot_list ftpusers user_list vsftpd.conf vsftpd_conf_migrate.sh
[root@station113 vsftpd]# cat ftpusers
# Users that are not allowed to login via ftp
root
bin
daemon
adm
lp
sync
shutdown
halt
news
uucp
operator
games
nobody
[root@station113 vsftpd]# echo opentow >> ftpusers
[root@station113 vsftpd]# cat frpusers
pam安装
root@www ~]# tar xf pam_mysql-0.7RC1.tar.gz
[root@www ~]# cd pam_mysql-0.7RC1
[root@www pam_mysql-0.7RC1]# ./configure --with-mysql=/usr/local/mysql --with-openssl
[root@www pam_mysql-0.7RC1]# make && make install
[root@www pam_mysql-0.7RC1]# ls -l /lib/security/
total 124
-rwxr-xr-x 1 root root 885 Mar 26 18:23 pam_mysql.la
-rwxr-xr-x 1 root root 119100 Mar 26 18:23 pam_mysql.so
[root@www pam_mysql-0.7RC1]# ln -sv /lib/security/pam_mysql.so /lib64/security/
`/lib64/security/pam_mysql.so' -> `/lib/security/pam_mysql.so'
安装mysql服务器端
[root@www ~]# yum install mysql-sercer mysql-sever mysql-devel pam-mysql
[root@www ~]service mysqld start
登陆mysql
[root@www ~]# mysql
mysql> CREATE DATABASE vsftpd;
Query OK, 1 row affected (0.00 sec)
mysql> GRANT ALL ON vsftpd.* TO 'vsftpd'@'172.16.%,%'IDENTIFIED BY 'vsftpd';
Query OK, 0 rows affected (0.01 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
mysql> /q
Bye
验证一下是否能够登陆
[root@www ~]# mysql -uvsftpd -h172.16.24.8 -pvsftpd

配置vsftpd
[root@www ~]# vim /etc/pam.d/vsftpd.mysql
auth required /lib/security/pam_mysql.so user=vsftpd passwd=vsftpd host=172.16.24.8 db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=0
account required /lib/security/pam_mysql.so user=vsftpd passwd=vsftpd host=172.16.24.8 db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=0
以上请写你自己的地址。
~
注意:由于mysql的安装方式不同,pam_mysql.so基于unix sock连接mysql服务器时可能会出问题,此时,建议授权一个可远程连接的mysql并访问vsftpd数据库的用户。
.修改vsftpd的配置文件,使其适应mysql认证
建立虚拟用户映射的系统用户及对应的目录
[root@www ~]# useradd -s /sbin/nologin -d /var/ftproot vuser
[root@www ~]# chmod go+rx /var/ftproot/
请确保/etc/vsftpd.conf中已经启用了以下选项
anonymous_enable=YES《========启动匿名用户
local_enable=YES
write_enable=YES
anon_upload_enable=NO
anon_mkdir_write_enable=NO
chroot_local_user=YES
[root@www ~]# cd /etc/vsftpd
[root@www vsftpd]# vim vsftpd.conf
而后添加以下选项
guest_enable=YES
guest_username=vuser
并确保pam_service_name选项的值如下所示
pam_service_name=vsftpd.mysql
[root@www ~]# service vsftpd reload
Shutting down vsftpd: [ OK ]
Starting vsftpd for vsftpd: [ OK ]
[root@www ~]#

Article discusses strategies for handling large datasets in MySQL, including partitioning, sharding, indexing, and query optimization.

The article discusses dropping tables in MySQL using the DROP TABLE statement, emphasizing precautions and risks. It highlights that the action is irreversible without backups, detailing recovery methods and potential production environment hazards.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

The article discusses creating indexes on JSON columns in various databases like PostgreSQL, MySQL, and MongoDB to enhance query performance. It explains the syntax and benefits of indexing specific JSON paths, and lists supported database systems.
