- Through SSH, Connect to Server
- Type su -
- Type vi /etc/php.ini which is the php configuration file
- Check for the line safe_mode = on and select “i
- Change the line to safe_mode = off
- Save the file and exit
- Open Putty
- Select SSH
- Port is normally 22
- Click on Open
- If you are logging on to the server, click Yes to approve the connection
- Once you view the login prompt, enter the username and password
In order to access MySQL through SSH :
- Login
- Type su - to provide superuser access
- Type mysql -uadmin -p`cat /etc/psa/.psa.shadow`
- If you need to reset the password : mysqladmin -u admin -psetup password $PW
- Login
- In Domain Administration, click on backup
- Click on Create Backup and Remote FTP Server
- Enter the IP address of FTP backup Server
- Enter username and Password
- Enter Description of backup file
- Click on Backup
These days Windows 2003 Server and Windows 2008 Server are much prefered. Following are the options that are normally provided :
- Windows2003 Web Edition
- Windows2003 Standard Edition
- Windows2003 Enterprise Edition
All three are setup on the same platform, however they are advanced in each step, such as Windows2003 Server Standard Edition is only supported upto 4GB RAM whereas Windows2003 Enterprise Edition is supported with 4GB and Above and known to use for clustering servers. It can support upto 1TB of RAM with Hot-Swap. It also provides virtual solutions which are used on Windows VPS nodes even though VPS’s are installed with Windows2003 Server Standard Editions on each VPS’s.
Load balancing servers are used for application management and load management over servers. These are setup in various ways such as Apache Web Servers on one physical hardware and MySQL database server on another physical hardware. This improves performance and reduces the failure factor. However, it is also known the Clustering of MySQL servers are expensive. High-end Configuration Servers can easily be setup as per client’s requirements. Normally 2 or more servers are combined to be known as load balancing servers. Each Web Server has public IP as well as Internet LAN IP. Mostly, LAN over Vlan is preferred. Another setup includes firewall configuration which allows only filtered traffic as inbound connections.
It is setup in a situation where SQL queries are distributed among the database servers. It allows connection through port 1433 for MS SQL and 3306 for MySQL for database servers. IP tables and TCP / IP firewalls on load balancers will remove the requirement of additional hardware firewall and will definitely save on cost.
Colocation has disadvantages which are as follows :
- Harware Price
- Installation Source
- Hardware fix
- CD installations
- Tech presence
- Server Monitoring
- Cabinet Cost
- Power Supply Cost
- Switches Cost
- Router Cost
Dedicated Servers are setup within 24 hours with full access over the server.
Following are few of the best dedicated server backbone providers :
- Level(3)
- AboveNet
- Newnet
- LINX peerings
- XChangePoint peerings
- LonAP peerings
- Savvis
- PCCW
- Telia
- Cogent
Dedicated Servers need security that will keep them safe from attacks or misuse of resources. Software firewalls can be installed on the server on Linux as well as on Windows Dedicated Servers. Cisco are known to be one of the best firewall appliances today. Juniper is equivalent of the performance. There are normally two types of firewalls. One is shared firewall and another is dedicated server which allows complete access over the firewall. However, when it comes to price, dedicated firewall is costly when compared to shared firewalls.
Redundant in computer language refers to setup of the server redundantly. This means failure of hardware is reduced and best quality hardware servers. This can be one server or more than one server .i.e. load balancing servers which include high volume traffic utilization. Redundancy refers to management of load.
