Installing MySQL system tables...

170622 2:42:34 [Note] /application/mysql/bin/mysqld (mysqld 5.5.49) starting as process 7032 ...

OK

Filling help tables...

170622 2:42:35 [Note] /application/mysql/bin/mysqld (mysqld 5.5.49) starting as process 7039 ...

OK

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/application/mysql/bin/mysqladmin -u root password 'new-password'

/application/mysql/bin/mysqladmin -u root -h zabbix-server password 'new-password'

Alternatively you can run:

/application/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /application/mysql ; /application/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd /application/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/
