Recently mysql crashed and I had no choice but to backup the contents of var/lib/mysql
to /home/backup/
and re-install the database.
after re-installing mysql server,
renamed /var/lib/mysql to mysql.orig
in /var/lib, I made a directory mysql
moved the contents from the home/backup
folder to /var/lib/mysql
Now by running mysql -u user -p
and when I call show databases
It give s the following error :
MySql : ERROR 1018 (HY000): Can't read dir of '.' (errno: 13)
How to solve this?
You need to set ownership and permissions for directory:
chown -R mysql:mysql /var/lib/mysql/ #your mysql user may have different name
chmod -R 755 /var/lib/mysql/
Note: -R makes commands recursive - you may omit it, if there is no subdirs in /var/lib/mysql/.
Source: mysql error : ERROR 1018 (HY000): Can't read dir of '.' (errno: 13)
For future users. Two more steps are needed: 1. chown -R mysql:mysql /var/lib/mysql/ 2. service mysql restart
And you are done! All your databases are back.
