很开心，经过不懈的努力，经过三番五次的和DA官方沟通，重要给yqf.me开通在线修改DA授权的权限了，这样的好处是，网友在yqf.me购买的DA授权，如果将来换IP和系统了，只需要给我发个邮件或者QQ或者旺旺等各种方式告诉我，我在线的话，可以立即变更DA授权。 Continue reading

directadmin修改上传文件大小限制
cd /usr/local/lib
vi php.ini
max_execution_time = 0 默认是30秒，如果无限制，修改为0；
post_max_size = 208M 默认是32M，根据情况调整大小；
upload_max_filessize = 200M 默认是8M，根据情况调整。
最终上传文件大小限制是取决于upload_max_filesize，而且upload_max_filesize<post_max_size.
Directadmin如何屏蔽ip阻止Brute Force Attack详细教程
自从安装了DA面板后，Brute Force Attack暴力破解DA后台密码就没有停止过，或许见多了就不怪了，但是老是收到诸如此类的信息：Brute-Force Attack detected in service log from IP(s) 106.187.43.249，总不是一件让人很愉快的事儿。
directadmin官方有教程，如何屏蔽ip阻止Brute ForceAttack
http://help.directadmin.com/item.php?id=380
以下我将官方的教程汉化下：
1)第一步，配置iptables，让block_ip.sh生效，DA官方的iptables文件适用于CentOS/Fedora，目前没有在Debian或者FreeBSD上测试，或许支持，或许不知道debian/FreeBSD。
cd /etc/init.d
mv iptables iptables.backup
wget http://files.directadmin.com/services/all/iptables
chmod 755 iptables*** 注意，ipables默认开启的ssh端口是22，如果你的ssh端口不是22，请手动修改iptables设置。
*** 注意，ipables默认开启的ssh端口是22，如果你的ssh端口不是22，请手动修改iptables设置。启动iptables:
/etc/init.d/iptables restart
2) 第二步，安装block_ip.sh脚本，block_ip.sh格式可以在found here找到 .
cd /usr/local/directadmin/scripts/custom
wget http://files.directadmin.com/services/all/block_ip.sh
wget http://files.directadmin.com/services/all/show_blocked_ips.sh
wget http://files.directadmin.com/services/all/unblock_ip.sh
chmod 700 block_ip.sh show_blocked_ips.sh unblock_ip.sh
3)创建blocked_ips文本:
touch /root/blocked_ips.txt
touch /root/exempt_ips.txt
去DA后台操作下Home–>Brute Forece Monitor–>IP info–>Blcok this IP.
4)自动封IP：
vi /usr/local/directadmin/scripts/custom/brute_force_notice_ip.sh
添加内容:
#!/bin/sh
SCRIPT=/usr/local/directadmin/scripts/custom/block_ip.sh
ip=$value $SCRIPT
exit $?;
chmod 700 brute_force_notice_ip.sh
以下是FreeBSD相关：
If you’re running FreeBSD with ipfw, you’d skip steps 2 and 3, and instead, add the following code to the file:
/usr/local/directadmin/scripts/custom/block_ip.sh
#!/bin/sh
echo “Blocking $ip with ipfw …<br>”;
ipfw add deny ip from $ip to any
exit $?
and don’t forget to chmod the block_ip.sh to 755.

2016年3.14日更新。好几年的问题，其实是Directadmin的一个bug，今天帮客户安装DA面板，系统是centos 6.x 64位，依然还是存在这个问题，耐心看了下官方的教程。简单处理下就可以了。
加入我们就一个盘，根目录是/，我们df -h是可以查看磁盘规划的。
我们执行 /usr/sbin/repquota / ，如果磁盘配额生效的，那会显示类似下面的：
[root@da182 ~]# /usr/sbin/repquota /
*** Report for user quotas on device /dev/xvda1
Block grace time: 7days; Inode grace time: 7days

问题就是他不显示正常的磁盘配额，所以我们要修改下配置：
/sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;
先执行下这个，如果还是报错。
那就修改下/etc/fstab设置，vi /etc/fstab
类似，添加红色的,usrquota,grpquota就可以了。
# Device Mountpoint FStype Options Dump Pass#
/dev/ad0s1a / ext3 rw,usrquota,grpquota 1 1
/dev/ad0s1e /tmp ext3 rw 2 2
proc /proc procfs rw 0 0
然后重启下机器。
然后再执行下：
/sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;
会看见磁盘配额生效了：
[root@da182 ~]# /sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;
quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.
quotacheck: Scanning /dev/xvda1 [/] done

各方面正常以后，再执行下：

就ok了。
Centos安装DirectAdmin教程
Centos安装DirectAdmin教程：
1、安装DA需要纯净的系统，之前有些朋友安装DA报错，请先执行：yum remove httpd* mysql* php*
2、预安装DA需要的环境：

2013年4月15日团购DirectAdmin面板网友需要提供的信息
DirectAdmin能安装在Ubuntu上吗？
2016年5月31日更新参考：
directadmin支持安装到ubuntu吗
DA授权后台是没有Unbuntu选项的，Ubuntu和Debian对应起来即可。
可以通过http://www.debian.org/releases/查看现在Debian发行版最新情况。
If my memory is correct, any Ubuntu version after (and including) 11.10 uses Debian 7, thus it’s not yet supported.Versions 9 and 10 (for the most part) use Debian 5, so things in betwen (prior to 11.10) would use Debian 6.If unsure, just install Debian 6. Check the /etc/debian_version prior to installation.
如果内存允许，11.10（包含）以后的Ubuntu，都可以和Debian7对应，但是目前不支持Debian7；Ubutu9和Ubuntu10，和Debian5对应，Ubuntu9(10)到Ubuntu11.10之间的Ubuntu和Debian6对应。
DirectAdmin如何查看使用的是哪个linux发行版？
ssh进去你的VPS或者独立服务器，敲下如下的某个命令，屏幕会显示到底您使用的是哪个linux/unix发行版：
cat /etc/redhat-release
cat /etc/debian_version
uname
uname -r
uname -m
编译安装directadmin完成，如何查看DirectAdmin是安装在哪个linux/unix发行版上呢，登陆DirectAdmin面板，点授权更新，即可显示。
看上图，显示DirectAdmin信息，编译版本是Centos5，编译日期是2012年11月28日，DA当前版本是1.42.1，最新可用版本是1.43，最近更新是2012年12月2日。
当然，安装DA完毕，你也可以自己ssh进系统，敲下：
/usr/local/directadmin/directadmin o
即可显示出同样类似的信息：
[root@da ~]# /usr/local/directadmin/directadmin o
Compiled on ‘CentOS 5.0’
Compile time: Nov 28 2012 at 02:10:56
Compiled with IPv6
DirectaAdmin支持哪些Linux（Unix）发行版？
Operating System:
Fedora 7, 8 (not supporting future versions)
RedHat Enterprise / CentOS 4.x, 5.x, 6.x (64-bit: 4.1 – 4.5, 5.x, 6.x)
FreeBSD 5.x, 6.x, 7, 7 64-bit, 8 64-bit, 9 64-bit (7.3 and 9 may require an exim recompile)
Debian 4.0, 5.0, 6.0. 64-bit: 5.0, 6.0
DirectAdmin官方退款策略
其实说了那么多，DA官方的退款策略大致如下：虽然30天内不满意可以退款，为了防止大家滥用退款政策，但是只退1个，而且只1次机会，当然这是对月付用户而言的。我比较关心的是内部批量价购买的话，支持退款否，答案是：不支持。所以官方给的建议是，先买一个DA，月付下，看看好用不，好用的话，30天内申请退款，然后再批量买20个，可以按照内部批量价。
Refund Policy
Monthly, Quarterly, and Yearly Licenses
Customers may request a refund within 30 days of installation if not satisfied with DirectAdmin Web Control Panel. To prevent abuse of this offer, only one refund per customer will be permitted. Licenses ordered after a refund are not covered by this refund policy, but licenses ordered before that time are covered if within the 30 day period. For example:
Refundable:
Gary orders three DirectAdmin monthly licenses and finds that he likes his old control panel software better. Fifteen days after the purchase he requests a refund on all three licenses.
Not Refundable:
A few days later Gary purchases one more DirectAdmin monthly license for a different server. Once again he finds that DirectAdmin isn’t for him. He cannot request a refund because he had a previous chance to try DirectAdmin.
Lifetime and Bulk Lifetime Licenses
Due to the permanent nature of lifetime licenses, refunds are not available when lifetime and/or bulk lifetime licenses are purchased. Customers wanting protection of the refund policy should:
1. Buy a monthly license
2. If satisfied with DirectAdmin, request a refund within 30 days
3. Purchase a lifetime license
