Very persistent /opt/lampp/bin/mysql.server: 264: kill: No such process. Xampp/ubuntu 16.04
Solution 1
I know this is an 4 month old topic and seems no reply yet. And I actually met one of you problem too (xampp status shows mysql not running), so just list the solution here so that if someone run into a similar situation, hope this could help a bit.
So this is a very complicated problem.
Because from what you described (very detailed),there are still many possible causes to this problem.
QUESTION: So here are some question summarized for your (from my experience):
- Is your
MySQL not running
happened during your first startup (xampp start / xampp startmysql)? - After installing xampp in Linux, have you customize MySQL configuration (default etc/my.cnf)?
- IF CUSTOMIZED Did you customize you database directory to a different location (default /opt/lampp/var/mysql)?
- IF NOT CUSTOMIZED As you mentioned you have access mysql command line, have you tried to SQL you database, or if the database was not even accessible (which means mysql server, named as mysqld, did not start properly)?
- Have you personally initialized/installed a mysql database (default bin/mysql_install_db)? Ok, these above questions should provide a basic trouble shooting idea.
SOLUTION:
1. error log problem
So this one should be the simpliest problem, and it could help us to better identify the error causes.
Check
a) in MySQL configuration (my.cnf) what is your running user? this should be a parameter under [mysqld] user=... (default mysql), we assume our configuration set to mysql
b) do you have an account for running user try terminal command id -u mysql
, if it returns an id number, then the account exist, else it should tell you no such user
. You need to have this user to run mysql server and write error log (by looking at the second part of your terminal record, your account should exist)
c) check your MySQL configuration (my.cnf) error log location, it should be under [mysqld] as a parameter log-error=... if this is not written, add to it (must be under [mysqld]).
d) check every directory of your log full path that (for example /var/log/mysql/error.log)
- /var should have
read
andexecute
authority for mysql user (which is at least ******r-x) pass create file (execute) authority - /var/log should have
read
andexecute
authority for mysql user (which is at least ******r-x) pass create file (execute) authority - /var/log/mysql should have
read
,write
andexecute
authority for mysql user (which is ******rwx) create and write file authority
So that your error.log file could be created here, if still not works, try to create it manually with owner as mysql, group as mysql and authority of 660.
2. MySQL server running status
there are several approaches to check this
a) use mysql.server (default bin/mysql.server) to do mysql.server status
command. If your MySQL server is up running, it should show SUCCESS! MariaDB is running.
b) use top
command to check if service is running, or use top | grep "mysqld"
. mysqld
and mysqld_safe
should in it.
c) login to mysql command line just like you did in terminal record 4 (this works part) and do command SHOW DATABASES;
this should also work.
So my xampp 7.4.1 in centOS 8 gives a problem of mysql.server ... kill no such process error like you did. that is because the database could not startup. Even you could run mysql.server start, it would fail eventually. And it is simply because of a corrupted database. So our solution is to re-initialize (mysql_install_db) database file(s).
And also we run into plugin missing problem using
mysql_install_db
in Xampp. There are many search result on web, including changing core coding in xampp for a lower server version compatible control problem, but no luck. So the final way is to download an offical package of mysql and use thescripts/mysql_install_db
to complete the task.
3. Customized database location cause Xampp mysql not running status This is a much deeper problem, because I have confirmed that MySQL server is running properly.
I did
[root@server ~]# /opt/lampp/xampp status
Version: XAMPP for Linux 7.4.1
Apache is running.
MySQL is not running.
ProFTPD is running.
[root@server ~]# /opt/lampp/bin/mysql.server status
SUCCESS! MariaDB running (xxxx)
So this shows that xampp is fetching service status incorrectly (like another post MySQL Database starts on Terminal But not on XAMPP )
I could trace down in detail how xampp works, but in /opt/lampp/xampp
script file, I found /opt/lampp/share/xampp/status
and /opt/lampp/share/statusraw
Go further into it (both /opt/lampp/share/xampp/status
and /opt/lampp/share/statusraw
file),
/opt/lampp/var/mysql/` /bin/hostname`.pid mysqld
As my database was customized to localized directory, this means the pid file will not be in /opt/lampp/var/mysql
, and this status will always return incorrectly.
So changing this into my own database pid location solved the problem.
Solution 2
Solution
-
Step 1: check if the mysql service status
service mysql status
as you can see, the service is already running.
-
Step 2: stop the service using the command service mysql stop. you will be prompted to provide your password, just do it.
service mysql stop
-
Step 3: check mysql status again and verify that it is disabled
service mysql status
-
Step 4: Now all you need to do is start xampp normally using:
sudo /opt/lampp/lampp start
Enjoy your day

I installed XAMPP on Ubuntu. MySql-server fails to run properly.
I tried many solutions, as suggested by google "/opt/lampp/bin/mysql.server 264 kill no such process", but to no avail.
Username (root), database name and password in "config.inc.php" and wp-config.php are correct.
richard@HAL:/opt/lampp$ ./lampp status Version: XAMPP for Linux 7.3.10-0 Apache is running. MySQL is not running. <- the problem ProFTPD is running.
===
richard@HAL:/opt/lampp$ sudo ./lampp startmysql XAMPP: Starting MySQL...ok. richard@HAL:/opt/lampp$ /opt/lampp/bin/mysql.server: 264: kill: No such process
===
root@HAL:/opt/lampp# service mysql stop root@HAL:/opt/lampp# ./lampp restart Restarting XAMPP for Linux 7.3.10-0... XAMPP: Stopping Apache...ok. XAMPP: Stopping MySQL...not running. XAMPP: Stopping ProFTPD...ok. XAMPP: Starting Apache...ok. XAMPP: Starting MySQL...ok. XAMPP: Starting ProFTPD...ok. root@HAL:/opt/lampp# /opt/lampp/bin/mysql.server: 264: kill: No such process
===
This works:
root@HAL:/opt/lampp# mysql -p -u root -p Enter password: *** Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 193 Server version: 5.7.28 MySQL Community Server (GPL) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.
I can also access http://localhost/phpmyadmin and see the wp1 database for my wordpress1 project (which I still need to begin due to all issues)
===
cd /var/log/mysql/ empty, no error.log (actually I deleted all in the process)
===
I tried also to stop/restart via /etc/init.d
Pressing start in ./manager-linux-x64.run shows MySQL in red after delay while trying to restart.
I applied this:
chmod a-wx ./etc/my.cnf
and this:mysql -u root -p chmod -R 777 /opt/lampp chown -hR nobody /opt/lampp chmod -R 755 /opt/lampp sudo service mysql stop sudo /opt/lampp/lampp restart
===
sudo netstat -nap | grep :80 [sudo] password for richard: tcp6 0 0 :::80 :::* LISTEN 18825/httpd tcp6 0 0 2a02:1811:bc1b:7c:33792 2a00:1450:400e:80b::443
===
lsof -i :80
returns nothing
===
Please tell me which commands I need to run for extra data you may need to diagnose the problem.
Then what does this mysterious error 264 mean? BTW, I also checked similar issues with error 260, although I don't have that particular error.
How can I systematically tune in on the root cause?

user2943111 about 4 yearsHi, thanks for your answer. I think the problems occurred due to a conflict between MariaDB and MySql. I solved it the easiest way I could think of: I removed XAMP and installed LAMP stack. But like you said, your answer can help others.

id -u mysql
No user for me. Sosudo adduser mysql
andsudo chown -R mysql:mysql '/opt/lampp/share/mysql'
and/var/mysql
and/lib/mysql
then delete all files from/temp
. Then it worked for me. -
user2943111 over 3 yearsThanks, I will try that some day. At the time when I needed a solution, I just installed a LAMPP stack myself after removing XAMP. That is a lot more work, but it did the job. The problem seems to be caused by mixing mariadb with MySql.
