mysqld_multi errors when starting servers, servers start when run manually
I am setting up multiple instances of mysql 5.5 server on a single host and trying to manage the instances using the mysqld_multi tool. Ia m able to get each instance to run without issue when I start each manually via nthe following command.
Code:
mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/$HOSTNAME.pid --socket=/var/lib/mysql/mysql.sock --port=3306 &
mysqld_safe --datadir=/usr/local/mysql/var2 --pid-file=/usr/local/mysql/var2/$HOSTNAME.pid2 --socket=/tmp/mysql.sock2 --port=3308 &
mysqld_safe --datadir=/usr/local/mysql/var3 --pid-file=/usr/local/mysql/var2/$HOSTNAME.pid3 --socket=/tmp/mysql.sock3 --port=3309 &
Code:
netstat -ntpl | grep mysql
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LIS
tcp 0 0 0.0.0.0:3308 0.0.0.0:* LIS
tcp 0 0 0.0.0.0:3309 0.0.0.0:* LIS
I have also verified seperate instances are running using ps -eaf, but will spare you the output.
When I try to run them with the mysqld_multi I get:
Code:
mysqld_multi start 1-3 --verbose
WARNING: mysqld_safe is being used to start mysqld. In this case you may need to pass
"ledir=..." under groups [mysqldN] to mysqld_safe in order to find the actual mysqld binary.
ledir (library executable directory) should be the path to the wanted mysqld binary.
/etc/my.cnf
Code:
[mysqld_multi]
mysqld =/usr/bin/mysqld_safe
mysqladmin =/usr/bin/mysqladmin
[mysqld1]
port = 3306
socket = /var/lib/mysql/mysql.sock

any tips to help trouble shoot this or configuration pointers would be appreciated |
