Yes, the site settings are correct and this problem occurred after a few months and mysql suddenly stopped working. I turned on mysql with the following commands, but now the sites are not loaded.
cd /www/server/data/
mv ibdata1 /tmp/ibdata1
mv ib_logfile0 /tmp/ib_logfile0.bak
mv ib_logfile1 /tmp/ib_logfile1.bak
But the command mv ib_logfile1 /tmp/ib_logfile1.bak did not work
I ran the ps aux | grep mysql command
