upgrading from 4.14.-r1 up [ebuild U ] dev-db/mysql-4.1.19 [4.1.14-r1] creates a n mysql which does not set socket file, so I can't get a connection. downgrading agin to 4.1.14-r1 solves the problem sh-3.1$ ls /var/run/mysqld/ -l total 4 -rw-rw---- 1 mysql mysql 6 May 14 18:56 mysqld.pid srwxrwxrwx 1 mysql mysql 0 May 14 18:56 mysqld.sock sh-3.1$
is the mysql daemon started ? look at the log files for any error, the size of the innodb logs has changed preventing the daemon to start.
