Bug#24619033 - UNABLE TO START MYSQLD DUE TO CHANGES IN
MYSQLD_SAFE
DESCRIPTION
===========
Starting a mysql server by running init script:
/etc/init.d/mysqld start
is failing. This is happening after the changes done in
script 'mysqld_safe' as a patch to Bug#24464380.
ANALYSIS
========
Say customer's /etc/my.cnf has following content:
[mysqld_safe]
.
.
ledir = /mysqld_ledir
mysqld = mysqld_wrapper
Patch to Bug#24464380 prohibits using "mysqld" (and few
other variables) in config file due to privilege reasons.
Since mysqld init scripts internally calls 'mysqld_safe'
script, the existing configuration has started failing.
FIX
===
In the init script, we now pass MYSQLD_OPTS as the first
argument (expected to be read from /etc/sysconfig/mysqld)
to mysqld_safe command. This new variable can have all the
mysqld_safe's special options as a string containing command
line arguments. For example:
MYSQLD_OPTS=" --ledir=/mysqld_ledir --mysqld=my_wrapper "
NOTE TO THE DOCUMENTATION TEAM
==============================
As mentioned above, the prohibited variables have to be
moved from /etc/my.cnf to /etc/sysconfig/mysqld as a string
containing command-line arguments in the form of variable
MYSQLD_OPTS. We can pass mysqld options as well in this new
variable which would be further passed to mysqld process.
