First of all, I apologize for asking this here. I know that this is probably not a Slackware question, but I am asking it here because I am running Slackware 64 14.2. I have a notoriously short attention span, which I am sure will interfere at some point or other, in dealing with this issue. I have found out in my researches of the past hour that this problem can often be caused by disk space issues. I have eliminated that:
Code:
root@caitlyn:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 707G 273G 399G 41% /
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 1.1M 3.9G 1% /run
tmpfs 3.9G 176K 3.9G 1% /dev/shm
cgroup_root 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/sda5 96G 47G 45G 52% /home
cgmfs 100K 0 100K 0% /run/cgmanager/fs
Plenty of disk space.
Here is the actual error:
Code:
root@caitlyn:~# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2 "No such file or directory")
Code:
root@caitlyn:~# ls -l /var/run/mysql/
total 0
As you can see, files that should be there are not. I suspected that mysql was not running, so I issued
Code:
root@caitlyn:~# ps -ef | grep mysql
root 19465 1789 0 17:05 pts/1 00:00:00 grep mysql
which confirms that it is NOT running. I then chmod +x to /etc/rc.d/rc.mysqld and then
Code:
root@caitlyn:~# /etc/rc.d/rc.mysqld start
root@caitlyn:~# 180122 17:06:14 mysqld_safe Logging to '/var/lib/mysql/caitlyn.err'.
180122 17:06:14 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
I looked at /var/lib/mysql/caitlyn_error:

And I start to get a little overwhelmed. It LOOKS like I should run mysql_upgrade, but when I do, I see:
Code:
root@caitlyn:~# mysql_upgrade
Version check failed. Got the following error when calling the 'mysql' command line client
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2 "No such file or directory")
FATAL ERROR: Upgrade failed
I have not used mysql since I installed Slackware last January, which might be causing some of my problems. Running mysql_secure_installation just asks for my root password a bunch of times and tells me that it can't do anything because of Error 2002. What should I do? Thank you in advance for any advice you can offer...
