安装PHP
# yum install -y php--安装
# yum install -y php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc --mysql关联
# service httpd restart --重启httpd服务使php生效，验证php安装是否正确http://localhost/info.php（需建立info.php文件）
# vi /var/www/html/info.php#建立php文件内容如下
<?
phpphpinfo();
?>
安装第三方源
http://pkgs.repoforge.org/rpmforge-release/ --Ctrl+F找到Centos6的对应rpm包

mysql数据库的备份与恢复
# 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
# 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
# groupadd -g 2001 ftpgroup
# useradd -u 2001 -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser
# cat /etc/passwd |grep ftpuser
ftpuser:x:2001:2001:proftpd user:/bin/null:/bin/false
# 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
# /usr/local/proftpd/sbin/proftpd
# 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
