安装apache
[root@ftp ~]# yum install -y httpd --安装
[root@ftp ~]# /etc/init.d/httpd start --启动
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name... ...  --在/etc/httpd/conf/httpd.conf 加入"ServerName localhost:80"或本地域名解析

数据库（ftp）的表结构

You can turn off this feature to get a quicker startup with -A

mysql数据库的备份与恢复
[root@amd240 ~]# mysqldump -u root -p --all-databases > all.sql   --备份全部数据库
Enter password:
-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.   --提示这个是因为mysql默认是不备份事件表的。加上--events --ignore-table=mysql.events参数即可；
/usr/local/mysql/bin/mysqldump -uroot -p --events --ignore-table=mysql.events --all-databases > all.sql
[root@ftp ~]# mysql -u root -p < /home/all.sql  --恢复备份数据（恢复时数据库要开启，完成后需要重启生效）

加用户和组
[root@ftp ~]# groupadd -g 2001 ftpgroup
[root@ftp ~]# useradd -u 2001 -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser
[root@ftp ~]# cat /etc/passwd |grep ftpuser
ftpuser:x:2001:2001:proftpd user:/bin/null:/bin/false
[root@ftp ~]# cat /etc/group |grep ftpgroup
ftpgroup:x:2001:

copy原ftp目录到新服务器（注意带属性copy及目录的权限和属组信息等）
# scp -prv /home/ftp root@yourhostname_or_IPaddr:/home/
必要时，需要手动修改各目录的属组

启动proftpd
[root@ftp ~]# /usr/local/proftpd/sbin/proftpd
[root@ftp ~]# pgrep proftpd
10573                       --有进程号说明服务起来了

proftpd -nd6 --启动可以查看错误信息
proftpd -l   --查看当前支持的模块 如是否支持mysql

以下是扩展的知识
一般使用mysqldump来备份和恢复，常用的几种常法：
（1）导出整个数据库(包括数据库中的数据）

mysqldump -u username -p dbname > dbname.sql

（2）导出数据库结构（不含数据）

mysqldump -u username -p -d dbname > dbname.sql

（3）导出数据库中的某张数据表（包含数据）

mysqldump -u username -p dbname tablename > tablename.sql

（4）导出数据库中的某张数据表的表结构（不含数据）

mysqldump -u username -p -d dbname tablename > tablename.sql
    
（5）如要对数据进行还原，可执行如下命令：

mysql -u username -p test_db < test_db.sql
