Koraki v WHM:

• Log into WHM and go to osnovna cPanel & WHM Setup
• Spreminjanje Primary IP tukaj z možnostjo, da je pravi “IP naslov (samo en naslov) ki se bodo uporabljali za določitev skupnih IP navideznih gostiteljev“
• Opomba: To ne bi dejansko bilo potrebno.

Prijava za SSH, in naredite naslednje:

• Edit /etc / sysconfig / omrežja-skripte / ifcfg-eth0
  • Change the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip

• Edit /etc / sysconfig / omrežje
  • Change the GATEWAY line here if it does not exist in the ifcfg-* file.

• Edit /etc / IPS
  • Odstranite novo primarni IP iz te datoteke, če je prisoten
  • Add the old primary IP to this file with the format ::

• Edit /var / cpanel / dolgočasno
  • Zamenjajte staro osnovno IP z novo primarno preiskave

• Edit /etc / hosts
  • Zamenjajte stare primarni IP z novim, če je potrebno. dns ime gostitelja bo treba posodobiti tudi

• Znova zaženite storitev omrežja, da bi nove preiskave primarni
  • omrežna storitev ponovni zagon
  • Opomba: You’re probably going to be disconnected at this point, in imajo za prijavo v ssh uporabo novega primarnega ip.

• Znova zaženite skript ipaliases, da bi do dodatnega IP
  • storitev ipaliases zagnati

• Run ifconfig and make sure all IPs show up correctly

• Posodobi dovoljenje Cpanel za nove osnovne preiskave

namestitev Iftop
namestitev 1、Prevesti in namestiti
Če lahko zbere in namestite Iftop na uradni spletni strani, da prenesete najnovejši paket izvorne。

Pred namestitvijo nastajanje okolje, potrebno za osnovne potrebe, ki so bili nameščeni，Na primer, da、gcc、autoconf 等。Namestitev Iftop morali namestiti tudi libpcap in libcurses。

Potrebna za namestitev odvisnosti na CentOS：

yum namestite flex byacc libpcap ncurses ncurses-devel libpcap-raz

Potrebna za namestitev odvisnosti na Debian：

apt-get install flex byacc libpcap0.8 libncurses5

Step 1

Run System Backup on the old server.

Admin Tools >> System Backup

We will be backuping home directories and mysql db’s manually so Uncheck and unselect the following options on System Backup

Add user home directories to directory list below

Backup httpd data

Backup MySQL Databases

Check and Select

Backup DNS data

Backup Directories and Files listed below

All directories/files listed in bottom section of the System Backup

now click on the Run System Backup Now icon . The backup will be stored mostly in /home/backup ( it will depend upon how you have set it in DA )

Step 2

rsync the system backup to the Newserver.

root@old:~# rsync -avurz -e ssh –delete /home/backup root@Newserver_IP:/home/backup

Step 3

On the Newserver restore the system backups one by one manually.

For example, for restoring your /etc/virtual directory,

root@new:~# cd /etc
root@new:~# tar xvzfp /home/backup/<backup_date>/custom/etc/virtual.tar.gz

Please check here for the complete paths and files used on a DirectAdmin system.

( Do take extra care while restoring /etc/passwd /etc/shadow /etc/group etc.. )

Step 4

Synchronise the home directory

root@old:~# rsync -avurz -e ssh –delete /home root@Newserver_IP:/home

Step 5

Backup and restore the mysql DB’s

On Oldserver

root@old:~# cat /usr/local/directadmin/conf/mysql.conf

Get the da_admin password from the above file

root@old:~# mysqldump -u da_admin -p –all-databases > /root/all_databases.sql

root@old:~# scp /root/all_databases.sql root@Newserver_IP:/root

On Newserver

root@new:~# cat /usr/local/directadmin/conf/mysql.conf

root@new:~# mysql -u da_admin -p < /root/all_databases.sql

Step 6

Use the ipswap script to change the Oldserver IP’s

root@new:~# cd /usr/local/direactadmin/scripts/

root@new:~# ./ipswap.sh Oldserver_IP Newserver_IP

Step 7

Update the nameservers to the Newserver IP’s.

Step 8

To resolve all the queries correctly to the new server . You will have to setup the multi server dns clustering on the new server

In a situation when a lot of disk space were freed on an in-ploop filesystem, use ploop balloon discard to optimize the ploop image size.

Iteratively try to relocate and discard unused blocks from a ploop image, reducing its size.

Note that ploop device and its inner file system should be mounted. If not, one can use –automount option to automatically mount ploop for the duration of the operation.

Option –defrag can be used to run a filesystem defragmentation utility (currently e4defrag2 on ext4 only) before the main operation.

Option –to-free can be used to specify a maximum disk space to be freed. In other words, stop the process once freed space exceeded requested size. Default is 0, meaning to try to free as much space as possible.

Option –min-block can be used to specify a minimum size of an extent to free. The smallest possible extent is 1 cluster (currently 1 MB), one can specify higher value to speed up the whole discarding operation.

Note that the same functionality is available by means of vzctl compact command.

HostMonster主机提供免费SSH，通过SSH导入/导出MySQL数据库还是比较方便的，具体步骤如下：

1. HostMonster主机导出MySQL数据库

下面的例子显示怎样导出一个MySQL数据库，经常将数据导出做个备份还是必要的，在命令行的操作步骤如下：

(1). mysqldump -u username -p database_name > FILE.sql
(2). Vnesite
(3). 提示输入密码
(4). 输入密码，Vnesite.

其中username, password 和 database_name 就是MySQL数据库的用户名、密码 和 数据库名。文件FILE.sql就是HostMonster主机上MySQL数据库的备份，现在可以下载到本地来保存。

2. HostMonster主机导入MySQL数据库

上传MySQL数据库备份文件(比如上面导出的文件FILE.sql)到HostMonster服务器上，然后执行如下命令：

(1). mysql -u username -p database_name < FILE.sql
(2). Vnesite
(3). 提示输入密码
(4). 输入用户名对应的密码，Vnesite.

wget http://www.kscub.com/share/mhash-0.9.9.9.tar.gz
wget http://www.kscub.com/share/libmcrypt-2.5.8.tar.gz

解决方法：

ena、先查看一下php-fpm的启动情况：（到底是不是这个问题造成的）

二、下载mhash包：

wget http://www.kscub.com/share/mhash-0.9.9.9.tar.gz

三、下载mcrypt包：

wget http://www.kscub.com/share/libmcrypt-2.5.8.tar.gz
