We are running zabbix on ubuntu server, and recently we rebooted the machine, after reboot Zabbix dashboard is not showing up. Although, we are still receiving the alert messages.
Ubuntu version 18.04.3 LTS;
Zabbix Version 4.4.4
error:
This site cant' be reached
ipaddress took too long to respond
ERR_CONNECTION_TIMED_OUT
I tried sudo systemctl status apache2
Error message
I was able to solve the issue using these commands:
systemctl start firewalld
sudo ufw allow 10050/tcp
systemctl stop firewalld
sudo systemctl restart zabbix-server

I am trying to start/restart my apache server and MySQL in the xampp by using the terminal in ubuntu 18.04.
The Commands which I used to restart is :
sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop
sudo /opt/lampp/lampp restart
I have tried many solutions already.
can anyone give me the idea to start MySQL and apache server?
Thanks in advance.
With limited info provided, your system is probably on systemd, so you can restart using:
service apache2 restart
service mysql restart
Or
systemctl restart apache2.service
systemctl restart mysql.service
I have a docker with Ubuntu 16.04 and trying to install mysql-server in it.
Installation went fine (apt-get install -y mysql-server) and now is time to run a server:
systemctl status mysql
Failed to connect to bus: No such file or directory
How to find/install systemctl for Ubuntu 16.04 (docker) and are there alternatives?
Systemd is not installed on the ubuntu docker image. You can use the "service" command
service mysql start
service mysql status
You can also use the mysql docker image instead of installing mysql manually on ubuntu.
Ubuntu 16.04 is based on systemd, and systemctl tries to contact the daemon via d-bus. There are a number of solutions to solve this problem, one may be docker-systemctl-replacement.
I have installed mysql (maria db) on redhat.
My question is - how do I start and stop the server?
STEPS
I ran the command
$sudo yum install mysql
It gave long messages in the console while installing and and at the end said

$ sudo service mysql start
it gives messages

I am using Red hat version - Red Hat Enterprise Linux Server release 7.1 (Maipo)
I believe you've installed only the client. For the server do yum install mariadb-server. The package will install appropriate service file for you.
The name of the service though is mariadb. Well that is the case on CentOS 7 at least... So, after you install mariadb-server package do systemctl enable mariadb and systemctl start mariadb.
The service is called mysqld, not mysql. So:
$ service mysqld start
Or better yet, use the proper systemd syntax:
$ systemctl start mysqld
on lubuntu 14.04 (desktop) i have installed apache web server and mysql server and, because of low ram (only 1024mb), i decided to remove them from startup (with sudo update-rc.d -f apache2 remove and by editing the /etc/mysql/my.cnf file ).
now, every time i want to do some development i have to sudo service apache2 start and sudo service mysql start in a terminal. wich is fine.
my question is: could those commands be executed from a .sh file? a file that i can double-click it from my desktop?
so far i got
#!/bin/sh
sudo service apache2 start
sudo service mysql start
You can do it with scripts which you mentioned.
Apache:
#!/bin/sh
sudo service apache2 start
Mysql
#!/bin/sh
sudo service mysql start
I installed XAMPP for Linux a couple of days ago and was working fine. Today I do wrongly
chmod 777 /opt/lampp
then MySQL won't be started. then I completely uninstall XAMPP then again install XAMPP then following message come ::
Starting XAMPP for Linux 1.8.1...
XAMPP: Another web server daemon is already running.
XAMPP: Another MySQL daemon is already running.
XAMPP: Another FTP daemon is already running.
XAMPP for Linux started.
then I tried to stop MySQL by typing::
sudo service mysql stop
Then It shows that ::
mysql: unrecognized service
then I tried to stop apache server by typing::
sudo service apach2 stop
Then It shows that ::
apache2: unrecognized service
Any suggestion ??
Try:
sudo /etc/init.d mysql restart
