If users in your network access remote servers on non standard HTTP/S ports not listed in squid.conf, your browser will show an error page :
ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: http://xxx.xxx.xxx.xxx:1000 (this is an example)
The following error was encountered:
* Access Denied.
Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

This ports restriction help limit unauthorized request.
Upgrading cPanel is a lot easy than upgrading Plesk, especially if we use WHM (Web Hosting Manager).
1. Log into WHM
2. Go to Apache Update in Software Category
3. Click Load Previous Config, uncheck previous php version and check the new php version. Same with mysql
4. Press Start Build
Note : some components also provided, such as xml-rpc, not just php and mysql. So read through options available in Apache Update, before Start Build
Stat in one of servers is turn off and doesn’t updating for two days.
Check ‘root’ user crontab
crontab -l
output : 7 4 * * * /usr/local/psa/admin/sbin/statistics >/dev/null 2>&1
Check cron logs for records about the statistic utility executions
vi /var/log/cron
Check apache logs size. Make sure no bigger than 2GB.
Check database directories (mysql : /var/lib/mysql) have read/write permissions to ‘mysql’ user
If every conditions above fit with your settings, then we must Run :
/usr/local/psa/admin/sbin/statistics (for all sites in one server)
or
usr/local/psa/admin/sbin/statistics �calculate-one �domain-name=domain.com (only for one specific domain)
Art can be everywhere.

If reboot and squid -k says it can not send stop signal again, means that squid.pid is missing
Check squid.pid in the system and if missing, here is what i can suggest :
Look into a previous post in this website, then shutdown squid
squid -k shutdown
Create squid.pid (usually squid.pid located in the same directory with log files)
touch squid.pid
squid.pid chmod permission
-rw-r--r--
squid.pid chown permission
root : squid
Since it’s empty, we must make Squid to rewrite a squid.pid file
Create Squid swap directories
squid -z
Run Squid
squid
then try reboot
The squid.pid file is missing or unreadable makes squid -k command don’t work (says it can not send stop signal). We kill Squid manually by finding the process ID with ps.
ps ax | grep squid
If there are more than one Squid process, be sure to kill the one that shows up as (squid).
example
500 ?? Is 0:00.01 squid -sD
505 ?? S 0:00.27 (squid) -sD (squid)
then kill it
kill -TERM 505
How to fix this? I learn that with a help from Squid Faq
Run squid again
squid
then do ps again
ps ax | grep squid
find squid process that shows up as (squid)
example : if the process id 82675 (remember this is example)
Create the PID file and put the process id number there
echo 82675 > /usr/local/squid/logs/squid.pid
note : /usr/local/squid/logs/squid.pid (location of squid.pid, this is probably different in your computer)
Then find the Squid process id. Send the process a HUP signal, which is the same as squid -k reconfigure
kill -HUP 82675
The reconfigure process creates a new PID file automatically.
A few things you need to know about Squid Swap Directories
1. Do not erase or delete using linux delete command. It can cause Swap Directories DIRTY.
2. You do not need to erase or delete Squid Swap Directories if you have no_cache deny (an instruction in squid for no-cache proxy) in squid.conf. Squid need that Swap Directories
3. Shutdown Squid before recreates Swap Directories.
4. If you recreates Swap Directories, disconnect any request to Squid. It can cause you a problem, in my experience, i can’t shutdown Squid properly in next event
I think this commands essential, because with this (only eight) commands you can create and edit various files with VI
i Insert new text, before the cursor.
escape/ESC
Once you’ve entered input mode using the one of the a, i, O or o commands, use escape or ESC to quit entering text and return to command mode.
yy Copy the line the cursor is on
dd Delete the line the cursor is on.:w
Write the file back to the file with the name that you originally used as an argument on the vi command line.
:w or :w!
Write the file back to the file with the name that you originally used as an argument on the vi command line.
:w file_name
Write the file back to the file with the name “file_name”.
:q!
Quit, discarding any modifications that you may have made.
:wq!
Write the file back to the file with the name that you originally used as an argument on the vi command line and Quit
