Not Acceptable! An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security. Using Cpanel on HostGator

Summary:

Not Acceptable! An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.

Problem or Goal: 

Faced this problem on one of my websites hosted on the shared plan on HostGator's Cpanel.
It's a question and answer website for Telecom and ICT experts, i got this error trying to post my answer to this question:

https://braindrain.expert/index.php/question/how-to-configure-traffic-policing-per-sub-interface-for-bandwidth-limiting-on-cisco-asr-router/#answer-7661


Cause: 

I contacted HostGator help on live chat:
https://gator4043.hostgator.com:2083/cpsess4074748396/frontend/hostgator/home/help.html

and this was their action and response:

"Thank you for holding, I appreciate your patience.

I checked for the server and the URL was blocked or malware attack reason. I have whitelisted the rule ID which was blocking the URLx

You can now check submitting an answer to this question"




Solution:

Apparently they said that the URL was suspected to be malware attack and was blocked, however they don't give details of the rules used to mark URLs as malware.

They white-listed the URL and i was able to submit the answer. 


Problem Solved?

Yes, but i think it's only a work around fix, and i might run into the same issue again, the best way would be if they give you access to the firewall rules/filter and you edit them. 

Error Response - mysqld: unrecognized service on Oracle Linux Server release 6.9

Summary: 

Am installing Cacti on Oracle Linux Server release 6.9 and MySQLD is among the many dependencies required.
I used "yum install cacti" but it installs all other dependencies apart from MySQLD (MySQL Server)!
so i was trying to run "service mysqld start" after the cacti + dependencies installation and got the error below.

Problem or Goal: 

[root@~]# service mysqld start mysqld: unrecognized service

Cause: 

Turns our "yum install cacti" doesn't automatically install MySQL server.

[root@~]# rpm -qa | grep mysql mysql-libs-5.1.73-8.0.1.el6_8.x86_64 nagios-plugins-mysql-2.2.1-4git.el6.x86_64 mysql-5.1.73-8.0.1.el6_8.x86_64 php-mysql-5.3.3-49.el6.x86_64

Solution: 

Install MySQL server again using "yum install mysql mysql-server" and try again.

[root@]# service mysqld start Initializing MySQL database:  Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h mtnsspebu password 'new-password' Alternatively you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default.  This is strongly recommended for production servers. See the manual for more instructions.
