Please be willing to work with our lead architect/developer to complete each milestone. This includes providing daily updates via HipChat and Skype voice. Successful completion means that milestone fully resolved and the items for that milestone, including both source and compiled code, have been fully deployed to, tested on and confirmed working on all three environments (dev, staging and prod servers/websites). Company determines when a milestone has been successfully completed. If all goes well on this project then there is potential for on-going contractor work.

500$ to provide us the solution. Before bidding make sure you already have a provider who can offer the solution because this is what we are primarily looking for. We are looking for someone to develop or provide us with a RAID 15 or RAID 16 cluster with total 100TB of space. It is for a web picture site. You would need to suggest us the service of a datacenter to do this. Datacenter should be outside USA. We have a budget of 300$ per month per cluster including your management services. We would prefer to rent cloud or dedicated server but if this does not exist for RAID 15 or 16 you would need to suggest us to buy the hardware and collocation.

Hi, I'm looking for someone to setup a "Linode 8GB", the stats on it can be seen here: https://www.linode.com/pricing I want it to have cPanel installed (I will supply licence) and to be fully configured for php/mysql speed. We don't host many sites but we want them to be as fast as possible, that is why we want to go for the 8GB Linode. All sites are either Wordpress (most), static HTML or Cakephp (these are going to be updated to the latest php7 compatibility version by our developer). In the past we've had issues on a linode that I don't think was properly setup. This is our current server so you can take a look at it and see if you can diagnose the issues to ensure they don't happen again on the new machine. A list of tasks would be: - setup new Linode - install cPanel - configure mysql & php for optimal speed for end user website visitors (need extremely fast page load) - analyse existing Linode to find issues and ensure they are not replicated on the new Linode - install packages that are required for the websites (git, maybe some php packages, can these be viewed on old Linode?) - secure Linode as best as possible and provide all access details etc - ensure log rotation is setup correctly so file system doesn't get filled (had issues with error_log in home directories before) - transfer all existing sites from the old Linode to the new one and create some blank cPanel accounts for sites we will move in the future: - 5 empty accounts to create - 7 cPanel to cPanel accounts in transfer (should be able to go via cPanel import function) - 1 account requires a manual import as the domain has changed - perform some checks after 2 weeks, 1 month and 2 months to test the Linode and make sure it is all working correctly - ideally we would also like to be able to use you in the future for ad hoc server checks/maintenance/fault finding etc Are there any other things you would recommend that we do as part of this work? Any other ideas you have for making the server and webpage load times fast? Such as optimising http keepalive or other such things? Thanks, Tom.

We recently have been unfortunate to experience an accidental "CHOWN /" event on our centos7 server. We have recovered and have working all production facing pages (php, apache, client side session/php session and mysql) all up and working. We still have file permission issues on a number of packages causing a few issues (that we can see): * phpmyadmin not working * security flaws due to permission mismatch This job is to return the server to a usable state, and then quote for ongoing SYS Admin work (ie. this has brought this problem and dependancy to the FORE, we need to move to a dedicated person to help with SYS admin). ON hand for any questions - between 7am and 11pm AEST preferred for work, so I can engage via chat etc when needed.

In order to filter all HTTP requests run on a Apache 2.2 server, I need to build a filter script to limit access and filter type of data processed by an PHP application. I can not refactor this application and want to build a generic filter, above this application, built with a specific Apache module. ### Details I've found a way of making this with [ExtFilter](http://httpd.apache.org/docs/2.2/mod/mod_ext_filter.html) on Apache 2.2. I want to obtain this with a PHP script in order to let my developer team to adapt this script to further needs. ### Features This script would be able to forbid following cases by returning a 403 HTTP response without processing request call * POST data with SQL request * POST data containing keywords amont a specific list * URL matching regex All parameters could be stored in JSON format (external configuration file) Work will be provided as GitHub project, with README documentation and a demo. ### Delay We need this before August 15th. Engagement will be done before July 25th.
