mysql啟動報錯解決-3

場景還原：

初始化

#/usr/local/webserver/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/webserver/mysql/ --datadir=/home/mysqldata

Installing MySQL system tables...

150205 11:48:00 [Note] Flashcache setup error is : ioctl failed

OK

Filling help tables...

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 --defaults-file=/home/mysql_config/my.cnf --user=mysql --basedir=/usr/local/webserver/mysql/ --datadir=/home/mysqldata  &

未啟動成功：

看日志報錯如下：

150205 16:17:03 mysqld_safe mysqld from pid file /home/mysql_config/run/mysql.pid ended

原因：

mkdir -p /home/mysql_config/log

手工建立的這個目錄，那麼預設是root權限，mysql無法寫入，是以不會生成mysql-bin.index這個檔案。

解決方法：

chown -R mysql.mysql /home/mysql_config/
