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/mysql56m1/bin/mysqladmin -u root password 'new-password'

  /usr/local/mysql56m1/bin/mysqladmin -u root -h 472322.com password 'new-password'

Alternatively you can run:

  /usr/local/mysql56m1/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/mysql56m1/bin/mysqld_safe &

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

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

Please report any problems with the ./bin/mysqlbug script!

奇怪配置文件里面的error.err并没有出现，而是产生了一个472322.com.err的文件，那么十有八九就是/etc/my56m1.cnf没有起作用，否则，不可能没有error.err的而是默认的472322.com.err 日志

我在第8步的时候执行init db的时候，命令中指定了 scripts/mysql_install_db  --user=mysql --basedir=/usr/local/mysql56m1 --datadir=/data56m1 --defaults-file=/etc/my56m1.cnf  配置文件是/etc/my56m1.cnf啊

再去看第8步执行的日志信息：

看到如下信息：

New default config file was created as /usr/local/mysql56m1/my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings


好像是说没有找到默认的basedir根目录下的my.cnf所以就自动创建了一个根目录的my.cnf。难道mysqld服务启动的时候没有识别--defaults-file参数？

11.2 check /etc/init.d/mysqld56m1 
打开/etc/init.d/mysqld56m1启动文件看看

extra_args=""

if test -r "$basedir/my.cnf"

then

  extra_args="-e $basedir/my.cnf"

else

  if test -r "$datadir/my.cnf"

  then

    extra_args="-e $datadir/my.cnf"

  fi

fi

...

# Get arguments from the my.cnf file,

# the only group, which is read from now on is [mysqld]

if test -x ./bin/my_print_defaults

then

  print_defaults="./bin/my_print_defaults"

elif test -x $bindir/my_print_defaults

then

  print_defaults="$bindir/my_print_defaults"

elif test -x $bindir/mysql_print_defaults

then

  print_defaults="$bindir/mysql_print_defaults"

else

  # Try to find basedir in /etc/my.cnf

  conf=/etc/my.cnf

  print_defaults=

  if test -r $conf

  then

    subpat='^[^=]*basedir[^=]*=\(.*\)$'

    dirs=`sed -e "/$subpat/!d" -e 's//\1/' $conf`

    for d in $dirs

    do

      d=`echo $d | sed -e 's/[  ]//g'`

      if test -x "$d/bin/my_print_defaults"

      then

        print_defaults="$d/bin/my_print_defaults"

        break

      fi

      if test -x "$d/bin/mysql_print_defaults"

      then

        print_defaults="$d/bin/mysql_print_defaults"

        break

      fi

    done

  fi

# Hope it's in the PATH ... but I doubt it

  test -z "$print_defaults" && print_defaults="my_print_defaults"

fi

...


看到都指向了my.cnf，先去找/etc/my.cnf，如果找不到，再找$basedir/my.cnf，为什么我init db的时候defaults-file设置无效呢？

12 copy config file to basedir directory
我尝试做了操作，把/etc/my56m1.cnf copy到$basedir/my.cnf

[root@472322 data56m1]# cp /etc/my56m1.cnf /usr/local/mysql56m1/my.cnf
