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:

/usr/local/webserver/mysql//bin/mysqladmin -u root password 'new-password'

/usr/local/webserver/mysql//bin/mysqladmin -u root -h kooxoo17.ktep3.kuxun.cn password 'new-password'

Alternatively you can run:

/usr/local/webserver/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 /usr/local/webserver/mysql/ ; /usr/local/webserver/mysql//bin/mysqld_safe &

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

cd /usr/local/webserver/mysql//mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/webserver/mysql//scripts/mysqlbug script!

Percona recommends that all production deployments be protected with a support

contract (http://www.percona.com/mysql-suppport/) to ensure the highest uptime,

be eligible for hot fixes, and boost your team's productivity.

啟動：

# /usr/local/webserver/mysql/bin/mysqld_safe --user=mysql &

150129 18:37:27 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

原因是

/etc/my.cnf 中的

datadir=/var/lib/mysql

而實際初始化的時候使用的datadir參數是--datadir=/home/mysqldata

修改為一緻的就好了！！！
