comment Apache/2.4.6 update causes 404s
Please search all apache config files for AllowOverrideList and AllowOverride. If you set AllowOverride to none htaccess is ignored.

comment Apache/2.4.6 update causes 404s
Try replacing the directory line in your config with the full path to your document root: Directory var/www/hivetracking-front/checkout/hive-tracking/public/ Since you have / there could be a more specific match changing your settings. Also are you sure your htaccess is even being processed? Try putting an error in the file and see if you get a 500 error.

Have you checked the AllowOverride settings in the main Apache file to see if they may be causing an issue.

comment Trying to install SSL: Private key does not match certificate
You should delete everything in WHM and then generate a new CSR. Then send this new CSR to your cert provider. This way the only private key in WHM would have to match the CSR you used. I suspect something is just getting mixed up along the way.

comment Trying to install SSL: Private key does not match certificate
You likely have the wrong private key for the cert. I've seen this happen a few times. See if you can get your SSL cert re-issued for free. If so, go into WHM and remove (make backups if you want) all SSL certs/CSRs/keys for the domain. Then generate a new CSR. This way there will only be one key on the server and WHM should get the match right.

comment MySQL connection errors when client server bandwidth is exhausted
What versions of MySQL and PHP (assuming) are you using? There used to be a bug in PHP that caused this. Also what is your connect_timeout? Lastly, if your network is exhausted -- you will simply need more network.

comment Log Archiving Solution
How large are the logs? How much data is being added per log rotation? The file size and rotation scheduled are key to finding a good solution.

comment File Monitoring on Ubuntu 12.04 Server
How many files are you trying to monitor? If it is few and they change infrequently, then performance is less of an issue. Also, if it is just one server, I would stick with a simple solution not requiring a centralized reporting tool.

comment Network In greater than Network Out?
You may also want to try the iptraf utility. Those charts are not very clear in terms of Megabits/sec. Using ipraf/ntop or something similar will allow you to see inbound/outbound bandwidth in real time. Also the netstat results are useful in identifying the port. I have seen cases where recycled IP addresses have a lot of traffic due to incorrect DNS pointing an old domain to your newly acquired IP.

comment Can't stop DDOS
What is the network speed of the server? If the attack is larger than your server's capacity, you will likely need to mitigate upstream and not at the server level.

comment Varnish running out of open ports, lots of SYN_SENT connections
You may want to consider setting net.ipv4.tcp_tw_recycle to zero - especially if load balancing. I've had issues with HAproxy at high concurrency with this enabled. Also, I would disable iptables during testing. I've seen some odd results with connection tracking when used in a load balanced environment.

You will need post more info along with configuration and initial results for this to be beneficial. Otherwise it will likely be closed as off-topic or too broad.

comment How to troubleshoot performance issues of PHP, MySQL and generic I/O
For a quick test, I usually run these 3 items: plain html/image (static content), php page with just phpinfo function, php page with a call to your database (just do a simple select). This is quick and really tease apart where you should be focusing your efforts.

comment How to troubleshoot performance issues of PHP, MySQL and generic I/O
What handler are you using for PHP? Are you certain you are on dedicated or a system with a hypervisor? Disk io is often slow on VPS/cloud offerings you may want to benchmark disk writes.

comment Apache Performance Tuning - Apache HTTP Server
If you want feedback, you will need to post more details. What are you testing? Just apache, a web application? How are you testing? What results do you have and what are the goals? You need more context for this to be a useful question.

comment Amazon EC2 pem file stopped working suddenly
Have you checked the contents of the mykey.pem file? I would need to confirm but I think SSH will send an invalid private key. I am not sure there is any integrity checks.
